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.
Neighbourhoods 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. 147 of Connecticut's 169 municipalities are rated at or above that figure. It also falls within the hurricane-prone region, 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 inches nominal width, which is what sits under the shingles on a great many pre-1950 Connecticut houses.
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.
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.
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.
