Roofers In Boston, MA.

If you own one floor of a three-decker, Boston will not let you pull your own roof permit. Most roofing pages never mention it. We put the permit rules, the license classes and the code dimensions on the page, then show you photos of your actual roof.

Not one page on the first screen of Google shows this formula

How Is a Boston Roof Permit Fee Calculated?

It is a formula, not a flat fee. Boston’s published building fee schedule sets a Short-Form permit at a $20 primary fee plus $10 for every $1,000 of the declared value of the work. A Long-Form permit is $50 plus the same $10 per $1,000. The city’s guidance on repairing a roof says you will need to apply for a Short-Form permit, and lists no exemption.

So the permit scales with the declared value on your scope. You can work it out yourself the moment a written estimate is in your hand, which means nobody gets to hand you a permit cost as a mystery line item.

$20

The Short-Form primary fee

Charged once, on application. It is the flat part of the formula and it does not move with the size of the job.

$10

Per $1,000 of declared value

The variable part. Take the declared value from your written scope, divide it by 1,000, multiply by 10, then add the primary fee. That is your permit.

$50

Long-Form, if the roof changes shape

Same $10 per $1,000 on top. Boston names a brand-new roof deck, or expanding an existing one, as Long-Form work.

Third-party guides quote a flat range for a Boston roof permit. The city publishes a formula. Those are different kinds of claim, and only one of them is checkable against a government document. Ask your roofer to show the permit line worked off your declared value rather than rounded to a guess.

A roofer who suggests skipping the permit is not saving you money. On a valuation-based schedule the fee is a small fraction of the work, and the permit is what puts a city inspector on your side of the job.

The Boston housing question nobody answers

Can You Pull Your Own Permit on a Three-Family?

Not you, if you own one floor of it. Boston limits homeowner self-permitting to a 1-2 family, owner-occupied home where you are doing the work yourself. The city’s roof page says it plainly: you must hire a contractor to perform the work if it is being done on a three-family or bigger dwelling. Its Long-Form guidance repeats it for anyone who owns a unit in a building with 3 or more dwellings, and uses one floor of a three-decker as the example.

That covers an enormous share of Boston. Dorchester, Southie, East Boston, Roxbury and Jamaica Plain are built out of wood-frame three-families, and a great many have been condo-ized into 3-unit trusts. 4 of the pages currently ranking for Boston roofing name the housing type. None of them connects it to the permitting rule, which is the part that changes what you are allowed to do this weekend.

There is a second reason not to self-permit even on a two-family where you legally could. Massachusetts regulation says payments from the Home Improvement Contractor Guaranty Fund may not be awarded to an owner who secured their own building permit for the work in dispute. One carve-out exists: the exclusion does not apply if the contractor failed to tell you about it, which the statute requires them to do in the contract.

1-2

Units, owner-occupied

The only case where a Boston homeowner can pull the permit and do the work. You take on the contractor’s role and full responsibility for meeting 780 CMR.

3+

Units, hire a contractor

Three-family and larger, and any condo in a building of 3 or more units. The contractor performing the work is the applicant. This is most of Dorchester.

$25k

What self-permitting can cost you

The Guaranty Fund pays actual loss up to $25,000 when a registered contractor leaves an unpaid judgment or award. Regulation excludes an owner who pulled their own permit. Older articles still say $10,000. The current figure is $25,000.

Eligibility needs several things lined up at once: a written contract, a contractor registered when you signed, which you can check on the MA Contractor Hub, work on a pre-existing owner-occupied home of 1 to 4 units, and the permit not in your name. Get most of it right and miss one and the fund is not there.

We file the Boston permit in our name, on every job. Ask us to write that into the contract and we will.

The number that should be in your contract and almost never is

The Boston Deck Problem Hiding in a License Code

Massachusetts has no standalone roofer license. It has 2 separate credentials from 2 separate agencies. HIC registration is consumer protection, run by the Office of Consumer Affairs and Business Regulation, and it is what opens arbitration and the Guaranty Fund to you. A Construction Supervisor License is the building-code credential, run by the Board of Building Regulations and Standards, and it is whose name goes on the ISD application. The state’s own guidance table lists new or replacement roofing as needing both, plus a building permit.

Here is the part that matters on a 1910 Boston house. There is a specialty CSL called Roof Covering, license code RF. The state’s published license table gives its scope as construction, reconstruction, alteration, repair or removal of roof covering, including repair and replacement of 25% of sheathing and 25% of sistering roof rafters.

Twenty-five percent. Boston’s older housing stock is board sheathing, often nailed up before the First World War, under roofs that have been quietly wetting the deck for a decade. A tear-off on a house like that does not politely stop rotting at 24 percent. If the license on your permit application is RF and the deck comes up worse than a quarter of the plane, the job has moved past the scope that license describes.

We are not going to dress that up as a rule the state publishes, because it does not. The table defines the scope; the conclusion is ours. What we will say is that it is a fair question to ask out loud, and the answer belongs in the contract next to the decking allowance.

RF

Roof Covering CSL

The specialty class. Fine for a covering replacement on a sound deck. Its published scope includes 25% of sheathing and 25% of sistering roof rafters.

2 lookups, same afternoon

HIC status and complaint history on the Contractor Hub. CSL number and class through the state license verification site run by the Office of Public Safety and Inspections. Ask whose license goes on the application, then look up that person.

Minor repair is a different row

The state table treats small roof repairs separately: HIC yes, CSL not ticked, permit a maybe. Worth knowing so you do not over-demand on a pipe-boot swap.

Powersol’s HIC and CSL numbers are not printed on this page yet. Our own rule is that we do not publish a license, insurance or certification claim until the exact number is confirmed in writing, and we would rather leave the line blank than fill it with something you cannot look up. Ask us on the call and we will read them out.

One paragraph, real money

What Is the Legal Limit on a Roofing Deposit?

No more than the greater of one third of the total contract price, or the actual cost of any materials or equipment of a special order or custom made nature. That is the wording in chapter 142A section 2, and it covers residential work over one thousand dollars on a pre-existing owner-occupied home of 1 to 4 units.

Architectural shingles pulled off a supplier’s shelf are not a special order. Quarried slate on a lead time can be, and the roofer has to be able to document the cost rather than assert it. A request for half the job in cash before the dumpster arrives sits outside the statute, and a 142A breach is also a chapter 93A problem.

1/3

The ceiling

Of the total contract price, before work starts, unless a documented special order costs more.

In writing, in dollars

Over one thousand dollars the agreement has to be written, with the payment schedule in dollar figures rather than percentages agreed on a doorstep.

Final payment

Not due until the work is complete to the satisfaction of both parties. Not when the truck pulls off your street.

Check the comp, not the paper

A certificate describes a policy. The Department of Industrial Accidents points the public at a proof-of-coverage database, and the DIA will confirm by phone. Ask to be named additional insured before the dumpster lands.

Boston is a row in a table, not a region

How Much Snow Must a Boston Roof Hold?

A 40 psf ground snow load and a 30 psf minimum flat-roof snow load. Those come from the municipal climatic table in the current Massachusetts Residential Code, which lists values town by town rather than by county. There is no Suffolk County figure to quote, which is a small tell when you see one on a roofing page.

The 10th edition of 780 CMR took effect on 11 October 2024 and has been the only code in force since 1 July 2025. If an estimator is quoting you figures from the 9th edition, they are reading an old brochure.

40

psf ground snow load

The Boston figure. It matters when somebody wants to swap heavy slate for asphalt, or add load to a deck nobody has looked at.

30

psf minimum flat-roof load

The number for the low-slope sections: three-decker rear roofs, additions, porch roofs, rear extensions.

2

layers is the ceiling

Massachusetts caps roof covering at 2 applications. A third means the roof comes off to the deck. On older Boston houses that turns an overlay quote into a tear-off, and it is a real line item rather than a day-1 surprise.

A measurement, not a brand name

Where Does the Ice Barrier Have to Stop?

From the lowest edges of all roof surfaces to a point not less than 24 inches inside the exterior wall line of the building. On roofs pitched 8:12 or steeper it also has to run not less than 36 inches measured along the roof slope from the eave edge. That is section R905.1.2 of the Massachusetts Residential Code, and the state publishes a plain-language FAQ on the requirement.

The code also says what the assembly has to be: not fewer than 2 layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet. Felt at the edge does not satisfy it. And Massachusetts does not treat any of this as conditional. The state climatic table marks ice barrier underlayment as required, with no qualifying footnote, which is why every roof in the city is inside the requirement.

Not one of the roofing pages ranking for Boston carries the dimension. Several say ice and water shield without a number. The word doing the work is inside: measured in from the exterior wall rather than up from the gutter, a typical Boston overhang puts the real run well past a single 3-foot roll, before you count valleys and penetrations. A crew treating it as a strip at the drip edge has not described an assembly an inspector can pass.

24

inches inside the wall line

Measured in from the exterior wall, not from the drip edge. That one word is why 2 quotes differ by rolls of membrane.

36

inches along the slope

The additional requirement on pitches of 8:12 and steeper, measured along the roof slope from the eave edge. 2 separate measurements, and a quote can meet one and miss the other.

0

dams stopped by membrane alone

The barrier is the backup, not the control. Heat leaking into the deck is what builds the dam. Air sealing, insulation and balanced ventilation are the fix, and they belong in the scope if ice is why you called.

Zero of the ranking pages explain the sequence

Why Landmarks Decides Before Inspectional Services Does

Boston will not issue your building permit until you hand the Building Department a Certificate of Appropriateness. You can file the permit application in parallel, which is a useful detail nobody publishes, but issuance waits on the certificate. There are 10 local historic districts in the city, and the trigger in most of them is exterior work visible from a public way.

Back Bay is stricter than that. All proposed exterior work is subject to the Back Bay Architectural Commission, with no visibility test at all. Beacon Hill counts views from the Common, the Public Garden, Storrow Drive, the Esplanade and the Longfellow Bridge, so a plane you think nobody sees may still be in scope.

The published standards are specific enough to end a kitchen-table argument. The South End says skylights are never allowed on mansard roofs, and that gutters, downspouts and flashing must be dark and non-reflective, with unfinished metal other than copper not approved. Beacon Hill requires roofing repair materials, flashing and gutters included, to duplicate the original or match appropriate existing materials, and treats roof decks visible from a public way as inappropriate to the district.

This is live practice, not theory. In November 2025 the Beacon Hill Architectural Commission approved a Chestnut Street re-roof specified as North Country Black slate, 20-ounce copper gutters kept to the same profile and dimensions, copper flashing throughout, ice and water shield over the entire roof, and an EPDM membrane on the flat section. Approved 4 to 0 by administrative review. That is the standard a visible Beacon Hill plane gets held to, and charcoal architectural shingles is not a conversation that ends well.

$50

The application tier for roofing

Boston’s Landmarks fee schedule puts a change to roofing materials, skylights or a roof deck in the $50 band. A new or raised dormer, or a roof headhouse, moves to $100.

15

business days to be judged complete

An application has to be complete 15 business days before the hearing to make the agenda. Commissions hear cases once a month, so missing the deadline costs 4 weeks, not 4 days.

Administrative review exists

Routine maintenance, repair and in-kind replacement can be approved by staff without you attending a hearing. That Chestnut Street slate roof went through this way. Ask whether your job qualifies before anyone books a hearing date.

If your address is outside the districts, none of this touches you, which is exactly why the top-10 lists leave it out. Check the address first. We will tell you which side of the line you are on before anyone talks about a start date.

The defining Boston roof, treated as an afterthought

Why One Three-Decker Needs 2 Roof Systems

Pitched at the street, low-slope or flat behind it. That means shingles and a membrane on the same job, joined by a transition detail, and that detail is where we find most of the water on these houses. 4 of the pages ranking for Boston roofing mention three-deckers. None of them explains one.

What an accurate three-decker scope has in it, and a single-family quote does not:

The rubber-to-shingle transition, detailed so the membrane runs up under the last course rather than being tarred to it. Parapet and party-wall flashing where 2 three-deckers abut, which is a shared-wall problem and often a shared-cost conversation. Stacked porch and piazza roofs, each a small low-slope roof with its own flashing into the main wall. Roof access through a scuttle hatch inside somebody’s third-floor unit, which means tenant notice, not just a ladder. And 3 sets of occupants whose week you are about to affect.

Our low-slope and flat roof work and our leak diagnosis are the same crew and the same estimate on these buildings, because splitting them is how the transition detail ends up belonging to nobody.

The transition

Where the pitched plane meets the membrane. Done as a lap and a bead of sealant it fails. Done as a proper termination it does not.

Party walls and parapets

2 buildings, one wall, and flashing that has to work for both. We photograph it and tell you if the neighbor’s side is the problem.

Access through a tenant’s unit

The scuttle is usually in the top-floor apartment. That is a scheduling and notice problem, and it goes in the plan rather than surfacing on the morning of the tear-off.

Absent from every page and every directory we checked

Who Files for Your Dumpster Space?

On a permit, if it is going in the street. Boston Public Works issues a street occupancy permit to restrict part of a street or sidewalk for a set time. The application asks how many dumpsters you are using and what size, and whether you will obstruct the sidewalk. You are meant to apply at least 7 business days before you need the space, and there is a base fee plus a daily charge by area, with metered spaces charged per space per day.

On a Dorchester street with no driveway, that is not a footnote. It sets your start date. It is also the single most common reason an urban roof job slips a week, and we have not found one roofing page in this market that mentions it.

The rest of the urban list, which we price rather than discover: staging on a lot with no side yard, hand-carrying material where a boom cannot reach, roof access over an abutting building and whose permission that needs, resident parking suspension for the crew, and a magnet sweep over a sidewalk and a tree pit rather than a lawn.

7

business days minimum

The lead time Boston asks for on a street occupancy application. Plan the roof around it rather than the other way round.

Dumpster or dump truck

On a tight street a dump truck that leaves each night can beat a container that needs a week of permitted space. We will tell you which one your street can take.

Ask before you sign

Any roofer quoting your Boston address should be able to say where the dumpster goes, who files for the space, and what it adds. A shrug is an answer.

Which Roofing Work Do We Take On in Boston?

Residential work, one point of contact from the first inspection to the final walkthrough. We install the full roofing system, because the roof is only as good as the deck, flashing, underlayment and ventilation under the shingles.

See All Roofing Services

From the roof, not the brochure

What Shows Up Under a Boston Roof

The problem is rarely the shingle. From the sidewalk a roof can look fine. Once you are on it you see lifted courses, granule loss, bad flashing, soft wood, nail pops, cracked pipe boots and water damage nobody notices until it is a much bigger number.

Rotted decking is the most common thing we find that was not in the first conversation. That is why a per-sheet allowance goes in writing before we start, rather than getting negotiated on your sidewalk with the roof already open.

Pipe boots

The rubber collar round a vent pipe. Costs a few dollars, cracks with age, and it is the most common slow leak we get called about. Plenty of quotes reuse them.

Flashing

Step flashing at walls and chimneys, and the counterflashing above it. Reused flashing is a leak with a delay on it.

Board sheathing

Pre-war Boston decks are planks, not plywood. Individual boards rot while the ones either side hold, which is why the percentage matters and why we photograph every sheet we pull.

Valleys

Where 2 planes meet, all the water goes. A valley detailed badly last time keeps leaking no matter how good the shingle above it is.

Ventilation

A hot attic cooks shingles from underneath and feeds ice dams from above. We check intake and exhaust on every inspection and write down what we find.

Nail placement

Nails driven high, overdriven or underdriven void shingle warranties and let wind lift the course above. Invisible once the next row goes on. We see it on tear-off.

What Belongs in a Boston Roofing Quote?

Put this in front of every roofer who quotes you, us included. 2 quotes are almost never the same roof, and the lower number is usually a smaller job wearing the same name.

  • Whose name goes on the ISD application, and the CSL class of that person. If the answer is your name, stop.

  • Short-Form or Long-Form, and the permit fee calculated off the declared value rather than guessed at.

  • What happens if the deck opens up worse than 25 percent, written down, with the license class that covers it.

  • Tear-off of how many layers, stated as a number, with the cost of pulling a second layer shown separately.

  • Ice barrier to 24 inches inside the wall line, plus the 36 inches along the slope if the pitch is 8:12 or steeper, with the distance on the page.

  • A decking allowance with a per-sheet price, so rotted board sheathing is a known number and not a sidewalk conversation.

  • Deposit as a dollar figure, and confirmation it is at or under one third of the contract price.

  • Does the address sit in one of the 10 historic districts? If yes, the Certificate of Appropriateness comes before the permit is issued.

  • Where the dumpster goes and who files the street occupancy permit, with the 7 business day lead time in the schedule.

  • On a multi-family, how roof access and tenant notice are handled, and who talks to the top-floor unit.

  • The pitched-to-low-slope transition detail, described, if the building has both. Not left between 2 trades.

  • HIC number and CSL number, both looked up the same afternoon, plus a current workers comp certificate with you named additional insured.

How it works

From First Call to Final Walkthrough

1

Inspection & photos

We inspect the roof and exterior, take photos, and explain what we see in plain English. On a multi-family we look at the low-slope section and the transition, not just the street plane. Free, with no pressure attached.

2

Written scope, not a number

Repair or replace, with photos behind it. Materials, layers, decking allowance per sheet, ice barrier distance, ventilation, permit type, street occupancy, timeline and cleanup. If it is not time yet, we say so.

3

Permits, then install

We file the ISD permit in our name, and the street occupancy permit if your address needs one. Historic district first if it applies. Then protect the property, tear off to the deck, replace bad boards at the agreed price, and install drip edge, leak barrier, underlayment, starter, flashing, new pipe boots, Timberline HDZ, ridge vent and ridge cap.

4

Cleanup & walkthrough

Magnetic sweep over sidewalk and tree pit as well as any lawn, debris haul-away, final photos, and a walkthrough with you. On a multi-family we hand the documentation in a form you can circulate to the other owners.

Most standard replacements go on in 1 to 2 days once material is on site and the weather holds. Our average install is about 1 day. Boston adds variables a suburban job does not have, and a Landmarks decision or a street occupancy lead time can move a start date by weeks. We will not guarantee a date that weather or a commission calendar can move.

Before you sign anything

8 Questions Worth Asking Before You Sign

Ask us these too. We would rather answer them than have you find out later.

1. Whose name goes on the ISD permit application, and what is that person’s CSL class?

2. Is this Short-Form or Long-Form, and what does the fee come to on my declared value?

3. What is your HIC number, and what does the Contractor Hub say about it today?

4. Show me the ice barrier detail to 24 inches inside the wall line on this eave.

5. How many layers are up there, and what if the boards come up worse than a quarter of the deck?

6. Deposit in dollars. Is it over one third of the contract price?

7. Is this address in a historic district, and who files the Certificate of Appropriateness?

8. Where does the dumpster go, and who applies for the street space?

Honest gaps

The Answers We Could Not Pin Down

5 things we went looking for and could not close from the public record. We would rather say so than publish a number we invented.

The 36-inch Boston ice barrier amendment. Several roofing sites say Boston, Brookline, Cambridge and Newton all locally amended the ice barrier from 24 inches to 36 inches inside the wall line. We looked on boston.gov, in the state code, and at the local amendment process in chapter 143 section 98. We found nothing. Until somebody shows us an approved amendment, 24 inches inside the wall line is the number we will write in your scope.

A median Boston roof permit valuation. The city’s approved building permits dataset carries a declared valuation and a permit type on every record, so this is computable. We have not computed it, and we are not going to quote somebody else’s guess in the meantime.

How long a Certificate of Appropriateness really takes end to end. The city publishes the 15 business day completeness deadline and a monthly hearing calendar. It does not publish a typical total. Do the arithmetic from your own submission date rather than trusting a blog’s estimate.

Whether a Boston roof job ever needs no permit at all. Not answerable from boston.gov. Inspectional Services can tell you for your specific scope.

Live HIC and CSL status for any named company. Ours included. Status changes. Look it up the morning you sign, not the week you searched.

Straight answers

Boston Roofing Questions, Answered

Do I need a permit to replace a roof in Boston?

Yes. Boston’s own guidance on repairing a roof says you will need to apply for a Short-Form permit, and it lists no exemption. A Short-Form permit covers work that does not change the building’s structure or use, which is what a straight replacement is. If the job adds a dormer, a new opening or a roof deck, that is Long-Form territory instead. Nobody should be re-roofing a Boston house without one of them.

How much is a roof permit in Boston?

Boston’s published building fee schedule sets a Short-Form permit at a $20 primary fee plus $10 per $1,000 of the declared value of the work. A Long-Form permit is $50 plus the same $10 per $1,000. So the permit scales with your scope rather than sitting at a fixed price. Take the declared value off your written estimate, divide by 1,000, multiply by 10, add the primary fee, and you have it. The fee is due when you apply. Third-party sites that publish a flat figure for a Boston roof permit are guessing at something the city states as a formula.

Can I pull my own roof permit in Boston?

Only if you own and live in a 1-2 family home and you are doing the work yourself. Boston’s Short-Form guidance limits homeowner self-permitting to a 1-2 family owner-occupied home. Its roof page is blunter: you must hire a contractor to perform the work if it is being done on a three-family or bigger dwelling. Own one floor of a three-decker, or a condo in any building of 3 or more units, and that rules you out. There is a second reason not to self-permit even where you can. Massachusetts regulation says the Guaranty Fund may not pay an owner who secured their own building permit.

What license does a Boston roofer actually need?

2 separate credentials from 2 separate agencies, plus the permit. HIC registration is consumer protection, it sits with the Office of Consumer Affairs and Business Regulation, and it is what gives you access to arbitration and the Guaranty Fund. A Construction Supervisor License is the building-code credential, it sits with the Board of Building Regulations and Standards, and it is whose name goes on the permit application. The state’s own guidance table puts new or replacement roofing down as needing both, plus a building permit. Massachusetts has no standalone roofer trade license, so a van that says licensed and insured has told you nothing you can look up.

What is a Roof Covering CSL and why does the 25 percent limit matter?

Roof Covering is a specialty Construction Supervisor License, code RF. The state’s published license table gives its scope as construction, reconstruction, alteration, repair or removal of roof covering, including repair and replacement of 25% of sheathing and 25% of sistering roof rafters. That percentage is the part worth knowing. Boston housing stock is largely pre-1940 board sheathing, and a tear-off on a house that has been leaking for years does not stop rotting at 24 percent of the deck. If the license on your permit is RF and the deck opens up worse than that, the scope of the job has moved past the scope of that license. Ask which class is on the application and what happens if the decking comes up worse than expected.

How much deposit can a roofer ask for in Massachusetts?

No more than the greater of one third of the total contract price, or the actual cost of any materials or equipment of a special order or custom made nature. That is the language in chapter 142A section 2, and it applies to residential work over one thousand dollars on a pre-existing owner-occupied home of 1 to 4 units. The contract has to be in writing, with the payment schedule stated in dollars. Architectural shingles off a supplier’s shelf are not a special order. Quarried slate on a lead time can be, and the roofer has to be able to document the cost.

How far does the ice barrier have to run under Massachusetts code?

From the lowest edges of all roof surfaces to a point not less than 24 inches inside the exterior wall line of the building. On roofs pitched 8:12 or steeper it must also run not less than 36 inches measured along the roof slope from the eave edge. It has to be not fewer than 2 layers of underlayment cemented together, or a self-adhering polymer-modified bitumen sheet. Massachusetts does not treat this as conditional: the state climatic table marks ice barrier underlayment as required, with no qualifying footnote. Measured inward from the wall rather than up from the gutter, a typical Boston overhang puts the real run well past a single 3-foot roll.

Does Boston require 36 inches of ice barrier inside the wall line?

We could not find any official source saying so. Several roofing sites claim Boston, Brookline, Cambridge and Newton have all locally amended the requirement from 24 inches to 36 inches inside the exterior wall line. We went looking on boston.gov, on the state code, and through the local amendment process in chapter 143 section 98, and found nothing. The state code applies statewide and local amendments need state approval after a public hearing. So the number we will put in your scope is the one we can defend: 24 inches inside the wall line, plus the 36 inches along the slope where the pitch is 8:12 or steeper. More membrane than that is a reasonable upgrade on a north-facing eave with a history of dams. It is not a code mandate, and we will not sell it to you as one.

Does my Boston roof need Landmarks approval before the permit?

If the property sits in one of Boston’s 10 local historic districts, yes. You can file the building permit application in parallel, but the city will not issue the permit until you hand the Building Department a Certificate of Appropriateness. In most districts the trigger is exterior work visible from a public way. Back Bay is broader: all proposed exterior work is subject to the Back Bay Architectural Commission regardless of visibility. Commissions hear cases once a month and an application has to be judged complete 15 business days before the hearing. Routine in-kind repair often clears by administrative review without a hearing at all.

What roofing materials get refused in a Boston historic district?

It depends on the district, and the published standards are specific enough to settle an argument. The South End standards say skylights are never allowed on mansard roofs, and that gutters, downspouts and flashing must be dark and non-reflective, with unfinished metal other than copper not approved. Original slate should be retained or repaired, and where a visible roof must be replaced, slate or a non-reflective look-alike may be allowed. Beacon Hill’s guidelines require roofing repair materials, including flashing and gutters, to duplicate the original or match appropriate existing materials, and treat roof decks visible from a public way as inappropriate to the district. Charcoal architectural shingles on a visible Beacon Hill plane is not a conversation that ends well.

What makes a three-decker roof different from a regular house roof?

It is usually 2 roofs on one building. A pitched plane at the street and a low-slope or flat section behind it, which means shingles and a membrane on the same job, joined by a transition detail. That transition, plus the parapet and party-wall flashing where 2 three-deckers abut, is where we find most of the water on these houses. Add stacked porch roofs, a scuttle hatch inside somebody’s third-floor unit, and 3 sets of tenants to coordinate. A quote written for a single-family ranch has not priced any of that.

Who decides on the roof when a three-decker is condo-ized?

The trust or association does, under its own documents, and the cost usually splits by beneficial interest percentage. That is a different decision path from a single owner saying yes, and it is worth starting early. We will put the scope and the photo documentation in a form you can circulate to the other unit owners, and we will hold pricing while that vote happens. The building permit still has to be applied for by the contractor performing the work, because the building has 3 or more units.

Where does the dumpster go on a Boston street?

On a permit, if it is going in the street. Boston Public Works issues a street occupancy permit to restrict part of a street or sidewalk, the application asks how many dumpsters you are using and what size, and you are meant to apply at least 7 business days before you need the space. On a tight lot with no driveway that permit is part of the job, not an afterthought, and it is one reason an urban roof takes more planning than a suburban one. We handle it. Ask any roofer quoting your street where the dumpster is going and who is filing for the space.

How long does a roof replacement take?

Most standard replacements go on in 1 to 2 days once material is on site and the weather holds. Our average install is about 1 day. Boston adds variables a suburban job does not have: staging on a narrow lot, street occupancy timing, tenant access on a multi-family, and a Landmarks decision if the property sits in a district. We will not guarantee a date that weather can move.

What happens if you find rotted wood after you tear the roof off?

It gets replaced at the per-sheet price already written into your scope. That is what a decking allowance is for. Rotted decking is the most common surprise on a tear-off, and on older Boston board sheathing it is closer to expected than surprising. A quote without an allowance moves that conversation to your sidewalk with the roof already open.
