Commercial roofing · Weymouth & the South Shore
Commercial Roofers In Weymouth, MA.
Weymouth charges $20 per $1,000 of construction value to permit a commercial roof. Single-family work is $10. Your building costs twice as much to permit as the house next door, and nobody selling roofs in this town prints either figure. Here is that number, the design loads your roof answers to, and the license question that disqualifies half a bid list.

Nobody Ranking For This Town Has a Weymouth Commercial Page
We measured the search results for commercial roofers in Weymouth. Roughly half are directory listings. Of the contractor pages that do rank, one is a homepage, one is a general city page where commercial is a single subheading, and one is a residential page with a commercial paragraph bolted on. Three roofing companies are headquartered in Weymouth itself. Between them they have no Weymouth page and no commercial page worth the name, and the top result for the biggest of them is its own directory profile.
Across every page in that set: zero design loads, zero permit figures, zero commercial prices, zero license-class explanations. One page cites a building code, once, and it is a residential code section on a residential page. So this page prints the numbers instead, names where each came from, and says plainly what we could not confirm. Powersol Roofing works Weymouth out of our shop at 100 Hancock St in Quincy, about four miles up the Fore River. Call (617) 631-5435 or request an assessment.

Weymouth Bills Commercial Roofing Permits At Double the Single-Family Rate
Twenty dollars per $1,000 of construction value, with a $100 minimum. That is the commercial and non-single-family rate on the Weymouth fee schedule effective 1 July 2024. Single-family work on the same schedule is $10 per $1,000 with a $50 minimum. The line the town draws is single-family against everything else, so a three-decker or a six-unit block sits on the commercial side of it. The town does not hide any of this. It publishes it. Not one roofing page competing for your building quotes it.
The rate is applied to the construction value written on the permit application. That makes the valuation a live number instead of paperwork. It decides the fee, and a valuation that does not match the work becomes a problem the building department finds long before your contractor absorbs it.
| Construction value on the application | Commercial at $20/$1,000 | Single-family at $10/$1,000 |
|---|---|---|
| $80,000 | $1,600 | $800 |
| $180,000 | $3,600 | $1,800 |
| $450,000 | $9,000 | $4,500 |
Run one comparison and the reason to care appears. A bidder who files your $180,000 reroof at an $80,000 valuation saves you $2,000 on the permit and tells the town your job is less than half the size it is. That gap surfaces at inspection, not at signing. Ask every bidder what construction value goes on the application, and ask before you pick one.
Then there is the part of Weymouth permitting that costs schedule instead of money. The town states it directly: for inspection requests, contact the inspector on weekdays between 7:30am and 9:00am, because inspectors leave promptly at 9am for their daily inspections. The department at 75 Middle Street in East Weymouth runs 7:30am to 3:30pm on 781-340-5004. A staged commercial reroof lives or dies on that 90-minute window, and a contractor promising to start Monday without having filed anything is describing a wish.
Your building is a row in a state table
Weymouth Is the Lighter Snow Town And the Windier One
A 35 psf ground snow load, a 30 psf minimum flat-roof snow load, and a 122 mph basic design wind speed at Risk Category II. That is Weymouth’s line in Table 1604.11 of 780 CMR Chapter 16, the municipality-by-municipality table the state actually uses.
Put it beside Quincy and the received wisdom inverts. Quincy carries 40 psf of ground snow against Weymouth’s 35, and 121 mph of wind against Weymouth’s 122. Four miles apart. The heavier snow sits north, the higher wind sits here. Anyone selling you a Weymouth roof on heavy New England snowfall is selling the wrong hazard.
| Value | Weymouth | Quincy |
|---|---|---|
| Ground snow load, Pg | 35 psf | 40 psf |
| Minimum flat-roof snow load, Pf | 30 psf | 30 psf |
| Wind V, Risk Category I | 112 mph | 111 mph |
| Wind V, Risk Category II | 122 mph | 121 mph |
| Wind V, Risk Category III | 130 mph | 130 mph |
| Wind V, Risk Category IV | 135 mph | 135 mph |
| Ss | 0.236 | 0.245 |
| S1 | 0.061 | 0.062 |
Wind being the governing hazard changes where the money goes on a Weymouth roof. Membrane attachment density has to rise at the perimeter and rise again at the corners, which is exactly where nobody walks and nobody inspects. Edge metal stops being trim and becomes the first thing the wind works on, because a roof that fails in uplift almost always starts at an edge and peels inward. A school or an assembly building is Risk Category III, which moves the figure to 130 mph and changes the fastening schedule across the whole field. After a wind event, the edge is also the first place to look: storm damage repair.
The question that disqualifies people
If Your Building Is Held In an LLC, You Cannot Be an HIC Customer
Home Improvement Contractor registration is the credential most roofers lead with, and it cannot cover your building. HIC is consumer protection for residential contracting on owner-occupied buildings of one to four dwelling units. 201 CMR 18.00 closes the door further: a corporation, partnership, business trust or charitable organization does not qualify as an owner. Most commercial property is held in exactly those structures. The registration is not weak for your job. It does not reach it.
What does reach it is the Construction Supervisor License, and the class on that license is the part that matters. Massachusetts licenses the supervisor rather than the company. The classes sit in 780 CMR 110.R5, and the Roof Covering specialty is quoted below word for word from the regulation.
| Credential | What it covers | Your building? |
|---|---|---|
| Unrestricted CSL | Buildings of any use containing less than 35,000 cubic feet of enclosed space | Yes |
| Restricted, 1 and 2 Family | One and two family dwellings and their accessory buildings | No |
| Roof Covering specialty, RF | Roof covering, plus repair and replacement of 25% of sheathing and 25% of sistering roof rafters | No |
| HIC registration | Owner-occupied residential, 1 to 4 dwelling units, and an entity does not qualify as an owner | No |
Now the part that is almost always described backwards, including by people who should know. 35,000 cubic feet is the ceiling of the whole license system, not a step up inside it. The Unrestricted class, the broadest one Massachusetts issues, covers buildings of any use containing less than 35,000 cubic feet. 780 CMR 107.6 exempts buildings under that same figure from construction control. One number, two provisions, interlocking: below it a licensed supervisor runs the job, above it a Massachusetts registered design professional has to provide construction control oversight. There is no larger license to upgrade to. If your building is over 35,000 cubic feet, the right question stops being which class and becomes who stamps the affidavit.
One date worth carrying. The Construction Supervisor examination moved to the 10th edition of the state building code on 1 January 2025, and the 9th edition stopped being accepted after 30 June 2025. Anyone sitting it since then tested on the code your job is being built under.
Two towns, two codes, one river between them
Weymouth Is Stretch. Hingham Is Specialized.
Weymouth runs the Stretch Energy Code. Hingham, across the Back River, adopted the Municipal Opt-in Specialized Code effective 1 January 2026. Weymouth has not. A specification written for one town is the wrong document in the other, and the roofing insulation line is where that difference lands.
Weymouth was designated a Massachusetts Green Community in December 2015, and its Stretch Code adoption took effect on 1 July 2016. That is a decade of Stretch Code history on buildings in this town, which is worth knowing before somebody pitches your reroof as a net-zero project or tells you the state has the strictest code in the country and leaves it there. The state has three layers. Weymouth sits on the middle one.
Where to settle it

Covering against assembly
Replacing the membrane alone and replacing the membrane plus the insulation are two different jobs to a building official. The second one is where an insulation requirement can attach. Which one your scope describes is worth settling before it is priced.
What we will not tell you
We are not printing an R-value for your job on this page. The commercial stretch code handles the prescriptive insulation table differently from the base code, and which path your building official applies decides the figure. Anyone quoting a confident R-value without settling that first is guessing with your money.

Both Federal Doors Closed This Year. Most Roofing Pages Have Not Noticed.
The two federal tax provisions a roofing salesperson might still mention are gone, and the Mass Save path is capped by building size. This is the section most likely to be out of date on every other page you read this week, so here is the position as of today with the dates attached.
The 25C Energy Efficient Home Improvement Credit is not allowed for property placed in service after 31 December 2025. It was a residential credit throughout, so it never applied to a commercial membrane roof, and it turns up in roofing copy anyway. The 179D energy efficient commercial buildings deduction, which is the commercial analogue and the one that would have mattered here, does not apply to property the construction of which begins after 30 June 2026. That date passed almost three months ago.
Mass Save still runs commercial weatherization incentives, and its own documentation sets the boundary: facilities undertaking weatherization improvements must be 20,000 square feet or less. Larger buildings, and hot roof conversions specifically, are routed to a custom review rather than the prescriptive path. If your Weymouth building is a 60,000 square foot industrial plate, the insulation is a construction cost and the custom conversation is a separate one.

Two things that changed under this town
New Flood Maps in 2025. A $65 Million Land Sale in 2026.
Weymouth’s floodplain ordinance now references the Norfolk County Flood Insurance Rate Map and Flood Insurance Study dated 8 July 2025. The town adopted it under Order No. 25-035 on 2 June 2025. Flood zone status does not change what membrane belongs on your roof. It changes permitting, insurance and what a substantial improvement triggers, and on the Fore River and the North Weymouth waterfront that is a live question rather than a theoretical one. Check your own panel on the current map instead of assuming the zone you remember still applies.
The commercial roof inventory in this town is quieter than the headlines suggest. Route 3 Industrial Park on Finnell Drive is five multi-tenant buildings at numbers 36, 50, 70, 86 and 106, roughly 247,000 square feet in total, developed between 1978 and 1986. Buildings of that vintage are exactly where original single-ply and built-up systems come due for replacement, recover or coating. That is the recurring commercial work in Weymouth, and it is the kind of building this page is written for.
The loud pipeline is Union Point, the former South Weymouth Naval Air Station. In July 2026 a $65 million land sale closed to a joint venture of Brookfield Properties and New England Development, covering more than 1,400 acres across Weymouth, Rockland and Abington. Worth separating what is built from what is drawn: more than 1,000 residential units have already been delivered there under previous developers. The 6,500 housing units and roughly 2 million square feet of commercial and retail space in current coverage are proposals, and every source reporting them says so. The MWRA water pipeline that gates much of it has been discussed at 2031 to 2032.
We do not treat Union Point as a 2026 bid list, and neither should anyone quoting you. It is the reason a Weymouth commercial specification written today should already assume solar-ready roof loading, Stretch Code performance paths and occupied-site staging, because that is the direction of this town’s commercial square footage even if the first large roofs land years out.
Three ways to work with us
From One Repair to a Roof Maintained on Schedule
Most owners meet us at a leak. The ones who spend least over a decade are on a schedule, because a problem found on a planned visit is a twenty-minute fix and the same problem found by a tenant is an insurance claim.
Repair
Leak tracing, seam and flashing repair, drain and scupper work, edge and coping repair, puncture patches and storm response, with the source photographed before and after.
Quoted line by line. No interior access needed for most membrane work.
Maintenance
Scheduled inspections, drains cleared, seams, flashings and perimeter attachment checked, small repairs done on the spot, and a dated photo report after every visit. The same method as a standalone roof inspection.
Spring and fall visits, plus a post-storm check.
Replacement
Core cut and moisture scan first, then a full system priced layer by layer, staged in sections so the building keeps operating and nothing is left open overnight.
Every layer specified and priced separately, with the manufacturer, thickness and attachment method named on each line.
Our Quincy page carries the building-type breakdown in more depth if your roof is a restaurant, a garage or a condo block: commercial roofing in Quincy. The membrane side of the same argument sits on our flat roofing page.

Six Questions, Including for Us
Put these in an email to every bidder. The one who will not answer in writing has told you something, and the question they dodge is the one worth writing down.
1. What construction value goes on the Weymouth permit application, and what does that make the fee at $20 per $1,000?
2. What Construction Supervisor License class will be on that application, and what is the number?
3. Is our building over 35,000 cubic feet, and if it is, who is the registered design professional providing construction control?
4. Is the wind uplift package worked to Weymouth’s 122 mph Risk Category II figure, with enhanced perimeter and corner zones, or to a national brochure?
5. Does the edge metal and coping in your number carry a tested uplift rating, and will you put that documentation in the closeout file?
6. How many coverings are on the roof now, what did the moisture scan show, and is this priced as a recover or a replacement?
Honest gaps
What We Could Not Confirm
Five things we went looking for and could not close from the public record. We would rather print the gap than a number we invented.
How many Weymouth properties the 2025 flood map actually moved. A property count was circulating. We checked both April 2025 Town Council meetings and neither discusses flood maps. The figure appears to belong to a different city. We are not repeating it.
The above-deck R-value your job will need. It depends on which code path the building official applies to your scope. One call settles it for your building and we have not made that call on your behalf.
A Weymouth-only commercial cost index. It does not exist. Published per-square-foot ranges for this market disagree with each other, and the disagreement is almost always about whether insulation, tear-off and cover board sit inside the number.
The MWRA pipeline schedule. Completion has been discussed at 2031 to 2032. We could not confirm a filing date beyond that from a primary source, so we are not putting one on this page.
Exact square footage at Route 3 Industrial Park. Listing aggregators say 247,625 square feet and the trade press at the time of sale said 246,625. We have written roughly 247,000 rather than pick a side.
Straight answers
Frequently Asked Questions
What does a commercial roofing permit cost in Weymouth?
Twenty dollars per $1,000 of construction value, with a $100 minimum. That is the commercial and non-single-family rate on the Weymouth fee schedule effective 1 July 2024. Single-family work is billed at $10 per $1,000 with a $50 minimum, so the same dollar of work costs twice as much to permit on a commercial building. A $180,000 reroof carries a $3,600 permit. The figure is calculated off the construction value written on the application, which means the valuation your contractor files is worth reading before it goes in.
What snow and wind load is a Weymouth commercial roof built to?
Table 1604.11 of 780 CMR puts Weymouth at a 35 psf ground snow load, a 30 psf minimum flat-roof snow load, and a basic design wind speed of 122 mph at Risk Category II, with 112, 130 and 135 mph at Risk Categories I, III and IV. Quincy, four miles up the road, carries 40 psf of ground snow and 121 mph of wind. Weymouth is the lighter snow town and the windier one. A quote written off coastal weather adjectives rather than that row is not answering the code.
Is a Home Improvement Contractor registration enough for commercial work?
No, and on most commercial buildings it is structurally impossible. HIC is a consumer-protection registration covering residential contracting on owner-occupied buildings of one to four dwelling units. 201 CMR 18.00 goes further and states that a corporation, partnership, business trust or charitable organization does not qualify as an owner. If your building is held in an LLC or a realty trust, you cannot be an HIC customer at all. A roofer answering the license question with an HIC number has answered a question about somebody else’s house.
What happens above 35,000 cubic feet of enclosed space?
The Construction Supervisor License system stops, and construction control begins. The Unrestricted class, the broadest one issued, covers buildings of any use containing less than 35,000 cubic feet. 780 CMR 107.6 exempts buildings under that same 35,000 cubic feet from construction control, so above it a Massachusetts registered design professional has to provide that oversight. It is one figure doing two jobs, and it is commonly described backwards as the point where you upgrade to a bigger license. There is no bigger license. Ask who the registered professional on your job is.
Which energy code applies to a Weymouth commercial reroof?
Weymouth is a Stretch Code town. It was designated a Green Community in December 2015 and its Stretch Code adoption took effect 1 July 2016. Weymouth has not adopted the Municipal Opt-in Specialized Code. Hingham, directly across the Back River, has, effective 1 January 2026. Two neighboring towns, two different energy code paths, and a specification written for one is the wrong document in the other. We are not printing an R-value for your job, because the commercial stretch code handles the prescriptive insulation table differently from the base code and your building official decides which path applies. Ask the Department of Municipal Licenses and Inspections before anyone prices the insulation line.
Are there still federal or Mass Save incentives for a commercial roof in 2026?
Both federal doors are shut and the Mass Save path is capped by building size. The 25C Energy Efficient Home Improvement Credit was not allowed for property placed in service after 31 December 2025, and it was a residential credit in any case. The 179D commercial buildings deduction does not apply to property the construction of which begins after 30 June 2026, a date that has already passed. Mass Save still runs prescriptive weatherization incentives, but its own documentation states that facilities undertaking weatherization improvements must be 20,000 square feet or less, with larger buildings and hot roof conversions routed to a custom review. Anyone subtracting a federal credit from a 2026 commercial roofing proposal is working from last year’s stack.
Did Weymouth’s flood maps change, and does it affect my roof?
Yes, on 8 July 2025. Weymouth’s floodplain ordinance now references the Norfolk County Flood Insurance Rate Map and Flood Insurance Study dated 8 July 2025, adopted by the town under Order No. 25-035 on 2 June 2025. Flood zone status does not change what membrane goes on a roof, and it does change permitting, insurance and what a substantial improvement triggers on a building near the Fore River or the North Weymouth waterfront. Check your own panel on the current map rather than assuming last decade’s zone still applies.
How do inspections actually get scheduled in Weymouth?
Early. The town publishes it plainly: for inspection requests, contact the inspector directly on weekdays between 7:30am and 9:00am, because inspectors leave promptly at 9am for their daily inspections. The department itself, at 75 Middle Street in East Weymouth, is open Monday to Friday from 7:30am to 3:30pm on 781-340-5004. That 90-minute window is the real scheduling constraint on a staged commercial reroof, and it is the reason a contractor who promises to be on your roof Monday without having filed anything is describing an intention rather than a schedule.
Request an assessment
Core Cut First, Then a Number
We open the roof before we price it. You get the layer count, the moisture reading, photographs of both, the permit valuation we intend to file, and a scope written layer by layer so it can be compared against anyone else’s. If a recover is the right answer on your building, we will say so.
