Our work in Thompson
Thompson is not yet on our completed-jobs list. It is 89 miles from our Bethel base, which is well inside the area we cover.
The town runs to 46.9 square miles, in Windham County.
Neighborhoods and villages here include East Thompson, Fabyan, Grosvenor Dale, Mechanicsville, North Grosvenor Dale, Quaddick, Quinebaug, West Thompson and Wilsonville. What is on the roofs differs across them, and so does what should go back on.
Design criteria for a Thompson roof
Appendix AY of the 2022 Connecticut State Building Code puts Thompson at an ultimate design wind speed of 120 mph, a nominal design wind speed of 93 mph. 148 of Connecticut's 169 municipalities are rated at or above that figure. Connecticut's amendment to R905.1.1 applies statewide, so a full tear-off here brings the sealed roof deck requirement with it.
Snow loading here is 40 psf at grade. At the state's maximum loading, structure is not an afterthought. Framing gets looked at here before anything is specified.
Connecticut amendments that apply here
Connecticut amends the international code on two points that touch nearly every roof we do. Ice barrier is required statewide under R905.1.2, running from the lowest roof edge to at least 24 inches inside the exterior wall line — measured along the slope, so a low-pitch roof needs more membrane than people expect. The sealed roof deck amendment, R905.1.1, carries an exception: it does not apply over lumber sheathing under 3 feet nominal width, which is what sits under the shingles on a great many pre-1950 Connecticut houses.
It matters here because 69.6% of Thompson homes predate 1980 - the median was built around 1967 - so plank decking and older fastening turn up regularly on tear-offs in this town.
The six-nail question comes up constantly. Code minimum in Connecticut is four nails per shingle. Manufacturers require six to honor their wind warranty. We install six. Both facts are true at the same time, and anyone presenting six as a code requirement has it wrong.
The weather a Thompson roof lives with
What does a roof here actually take? The closest thirty-year weather record is kept about 4 miles from the center of town, and NOAA's 1991-2020 normals are the honest answer.
Snow: 38 inches in an average year, which is about average for Connecticut. It falls across roughly 12 days that leave an inch or more, and 5 that leave three inches or more. The weight is not usually the problem. The problem is melt that refreezes at the cold edge of the roof and forces water back up under the courses, which is exactly what the ice barrier at the eaves is for.
Freeze-thaw: about 156 nights a year drop below freezing, and 29 days never climb above it. Each of those nights works on whatever is already loose - a lifted tab, a tired boot around a pipe, a nail that has backed out. Winter finds the weak spot and makes it bigger.
Rain: 50 inches a year, including about 13 days when an inch or more falls in a single day and 2 that top two inches. Volume like that finds a tired valley, an undersized gutter or a kick-out flashing that was never installed. Those are the three places we look first on an older roof here.
The town center is about 527 feet up - middling for Connecticut, where every few hundred feet of elevation adds snow and takes away melting days.

What has actually hit Thompson since 2015
There is a public record of severe weather, town by town. For the ten miles around Thompson, this is what NOAA confirmed across 2015-2026.
32 damaging-wind reports, the strongest put at 63 mph. In this part of the state wind is what takes roofs apart, and it does it quietly: lifted tabs reseal crookedly, seal strips fail, and the roof looks untouched from the street.
4 hail reports, the largest 1.75 inches across - about the size of a golf ball. Hail that big is not a cosmetic problem. It fractures the mat, punches through older shingles and dents everything soft on the roof, including vents, flashing and gutters.
Also on the record: 2 confirmed tornadoes touched down inside the same circle and the National Weather Service logged 24 winter-storm, heavy-snow or ice-storm events for Windham County over the same years.
After a storm like those, the sensible move is a look at the roof before anything leaks - we do that for free in Thompson, and you get the photographs either way. If there is damage, our storm damage report puts the photos, measurements and a written estimate in one place for your insurer.

Permits and inspections in Thompson
Thompson issues roofing permits through its building department. Jon Nolle is listed as the building official. Full-time staffing means inspections here rarely become the bottleneck. The published number is 860-923-9002. Written questions go to buildingofficial@thompsonct.org. We pull the permit as part of the job. No homeowner should be asked to pull their own roofing permit by a contractor working on their house.
A roof replacement permit in Connecticut is generally issued over the counter or online once the scope is submitted, with an inspection at completion. Where a house sits in a local historic district, or where zoning or health review applies, that approval comes first and can add real time. If your property is affected, we will tell you before the contract is signed rather than after the dumpster arrives.
Thompson's prewar share and what it asks of a roof
In Thompson, 27.6 percent of homes were built before 1940, according to the Census Bureau's 2019-2023 estimates. That is above the Northeastern Connecticut Planning Region, at 23.4 percent, and above Connecticut, at 20.4. New construction runs the other way: 9.8 percent of Thompson's housing dates from 2000 or later, where the regional share is 15.7 percent. Between those two ends, the town's median year built is 1967, level with the state, giving the typical house about 59 years of age in 2026.
Age changes what a re-roof is allowed to be. Under IRC R908.3.1.1, a roof that has soaked up water or deteriorated too far to serve as a base cannot simply be covered over, and the same section rules out a layover on slate or on a roof already holding two or more coverings. After many decades and possibly several re-roofs, a prewar house is likely to run into at least one of those limits, which makes a tear-off to the deck under R908.3 the likely route for older Thompson homes.
The chimney deserves attention during that work. IRC R1003.20 says a chimney needs a cricket when it runs wider than 30 inches along the ridge direction and does not intersect the ridgeline. With the old roofing off and the deck exposed, it becomes clear whether the chimney on an older house has one, and a missing cricket can be framed in before the new covering goes down.
Owners occupy 81.8 percent of Thompson's occupied homes, and 76.8 percent of its 4,269 housing units are single-family detached, both above the statewide 66.2 and 58.7 percent. Homes built before 1980 make up 69.6 percent of the stock. That group includes the pre-1978 target housing covered by EPA's Renovation, Repair and Painting rule, which applies to paid renovation that disturbs painted surfaces. A roof job that pulls painted trim or fascia on one of those houses falls under it unless an exception applies, such as the exterior minor-repair exclusion for 20 square feet of paint or less. The table below gives the rest of the estimates.
| Housing (ACS 2019–2023) | Thompson | Connecticut |
|---|---|---|
| Housing units | 4,269 | 1,536,049 |
| Owner-occupied homes | 3,277 | 939,912 |
| Share owner-occupied | 81.8% | 66.2% |
| Single-family detached | 76.8% | 58.7% |
| Median year built | 1967 | 1967 |
| Built before 1940 | 27.6% | 20.4% |
| Built 1940–1979 | 42.0% | 47.4% |
| Built 1980–1999 | 20.6% | 20.5% |
| Built 2000 or later | 9.8% | 11.8% |

How Thompson compares with the towns around it
Every town Thompson borders is rated for equal or stronger wind. Crossing the town line here means a heavier fastening schedule, not a lighter one.
| Bordering town | Design wind | vs. Thompson | Ground snow | County |
|---|---|---|---|---|
| Putnam | 125 mph | +5 | 40 psf | Windham |
| Woodstock | 120 mph | same | 40 psf | Windham |

Common questions about roofing in Thompson
Who is the building official in Thompson?
Jon Nolle is the building official on record for Thompson, per the State of Connecticut list of municipal building officials. Staffing changes — confirm with the town before relying on it.
How many nails per shingle should be used in Thompson?
Connecticut's code minimum is four. Shingle manufacturers require six to keep their wind warranty in force, and six is what we install. Six nails is a manufacturer requirement, not a code requirement.
Is ice barrier required on a Thompson roof?
Yes — Connecticut requires it statewide under code section R905.1.2, running from the lowest roof edge to at least 24 inches inside the exterior wall line. With a 40 psf ground snow load in Thompson, that detail is doing real work.
What wind speed does a roof in Thompson have to be designed for?
The 2022 Connecticut State Building Code assigns Thompson an ultimate design wind speed of 120 mph. That figure sets the fastener schedule and the manufacturer wind rating we specify.
Do I need a permit to replace a roof in Thompson?
Yes. A roof replacement in Thompson requires a building permit, and we pull it as part of the job. The building department's published number is 860-923-9002 if you want to confirm anything independently.
Does Thompson get hail?
Yes, and it is worth taking seriously. NOAA has 4 confirmed hail reports within ten miles of Thompson since 2015, the largest 1.75 inches across. That is destructive hail - it splits shingles and punctures the mat, and a roof caught by it usually needs replacing rather than patching.
Are ice dams a problem in Thompson?
They are the winter problem worth planning for. The nearest long-record station averages 38 inches of snow a year across about 12 days that leave an inch or more, and roughly 156 nights below freezing. That is the exact recipe for melt at the warm middle of a roof refreezing at the cold eave. Connecticut's code answer is an ice barrier at the eaves; the practical answer is that plus attic insulation and ventilation that keep the roof deck cold.
