Our work in Wilton
We have completed 4 roofs in Wilton. That figure comes from our own job records rather than an estimate, and it moves as we work. The town is 12 miles from Bethel.
The town runs to 26.8 square miles, in Fairfield County.
Neighborhoods and villages here include Cannondale, Georgetown, Gilbert Corners, North Wilton, South Wilton and Wilton Center. What is on the roofs differs across them, and so does what should go back on.
Design criteria for a Wilton roof
Roofs in Wilton are designed to an ultimate wind speed of 120 mph, which the code expresses as 93 mph nominal. The source is Appendix AY of the 2022 Connecticut State Building Code. 148 of Connecticut's 169 municipalities are rated at or above that figure. Connecticut's amended R905.1.1 applies statewide, so the sealed roof deck requirement is triggered on a full tear-off here.
Ground snow load in Wilton is 30 psf. The state's floor figure. Ice at the eaves does more damage in towns like this one than weight ever does.
Connecticut amendments that apply here
The state changes the model code in two places worth knowing about. R905.1.2 requires ice barrier everywhere in Connecticut, extending at least 24 inches inside the exterior wall line as measured up the slope. And R905.1.1, the sealed roof deck amendment, does not apply over narrow lumber sheathing — under 3 feet nominal — which is exactly what many pre-1950 houses in this state have.
It matters here because 63.6% of Wilton homes predate 1980 - the median was built around 1971 - 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.
Wilton weather, measured
What does a roof here actually take? The closest thirty-year weather record is kept about 8 miles from the center of town at Stamford 5 N, and NOAA's 1991-2020 normals are the honest answer.
Snow: 34 inches in an average year, which is on the lighter side for Connecticut. It falls across roughly 10 days that leave an inch or more, and 4 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 119 nights a year drop below freezing, and 16 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: 52 inches a year, including about 16 days when an inch or more falls in a single day and 3 that top two inches. That is a lot of water to move off a roof, and it finds the same three places every time: valleys, gutters that cannot keep up, and wall junctions with no kick-out flashing.

The storms Wilton has had since 2015
There is a public record of severe weather, town by town. For the ten miles around Wilton, this is what NOAA confirmed across 2015-2026.
64 damaging-wind reports, the strongest put at 70 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.
1 hail report, the largest 1 inch across - about the size of a quarter. At that size hail dents and bruises rather than punctures, which is why hail damage gets missed until the roof starts leaking two or three winters later.
Also on the record: 2 confirmed tornadoes touched down inside the same circle and the National Weather Service logged 31 winter-storm, heavy-snow or ice-storm events for Fairfield County over the same years.
None of that means a roof is damaged. It means it is worth looking. An inspection in Wilton costs nothing, you get the photographs whatever we find, and the storm damage report collects the evidence in one document if you need it.

Permits and inspections in Wilton
Permits for roof work in Wilton go through the town building department. Mark Lawrence is listed as the building official. The office is staffed full-time, so inspections here are generally easy to schedule. The published number is 203-563-0177. Written questions go to building@wiltonct.gov. We pull the permit ourselves. If a roofer asks you to pull it in your own name, that is a reason to stop and ask why.
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.
Wilton's 1960-to-1979 houses and the roofs on them
Wilton's largest block of housing dates from 1960 to 1979. According to Census Bureau estimates for 2019-2023, that bracket holds 38.8 percent of the town's 6,474 housing units, far above the 26.7 percent Connecticut shows for the same years. Another 25.8 percent went up from 1980 to 1999. Prewar houses, by contrast, make up only 10.8 percent of the stock, against 20.4 percent statewide and 16.2 percent in the Western Connecticut Planning Region. The median year built, 1971, is the same as the region's and puts the typical Wilton house at about 55 years old in 2026.
A house built between 1960 and 1979 is very unlikely to still have its original asphalt roof. The InterNACHI life expectancy chart gives 3-tab shingles 20 years and architectural shingles 30, adjusted up or down for weather, design, material quality and maintenance. So the roof on a typical Wilton house of that era is probably its second or third, and the owner's real question is how the last replacement was done.
That history decides what the next job can be. If an earlier replacement was laid over the old roof instead of tearing it off, the house now carries two layers. R908.3.1.1 does not allow a recover over two or more existing applications, or over a roof that is water soaked or too deteriorated to serve as a base. Either condition means the next Wilton roof starts from bare deck, and many of the 25.8 percent built from 1980 to 1999 are now reaching the same point on their own first or second roofs.
Age also brings a federal rule into view. The 63.6 percent of Wilton units built before 1980 include every pre-1978 home in town, and EPA's Renovation, Repair and Painting rule covers paid renovation that disturbs painted surfaces in that housing, subject to exceptions. On a roof job, painted fascia and trim are where that can come up; exterior work disturbing 20 square feet of paint or less is excluded as a minor repair. Wilton is 87.8 percent owner-occupied, against the region's 66.2 percent, and 83.5 percent single-family detached. Stallion Ridge's workmanship warranty runs 25 years. The table below lists every bracket.

How Wilton compares with the towns around it
Wilton shares its design wind figure with all 6 of its neighbors, so specifications carry across these town lines cleanly. The permit process does not — each town runs its own.
| Bordering town | Design wind | vs. Wilton | Ground snow | County |
|---|---|---|---|---|
| New Canaan | 120 mph | same | 30 psf | Fairfield |
| Norwalk | 120 mph | same | 30 psf | Fairfield |
| Redding | 120 mph | same | 30 psf | Fairfield |
| Ridgefield | 120 mph | same | 30 psf | Fairfield |

Common questions about roofing in Wilton
How many nails per shingle should be used in Wilton?
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.
Who is the building official in Wilton?
Mark Lawrence is the building official on record for Wilton, per the State of Connecticut list of municipal building officials. Staffing changes — confirm with the town before relying on it.
Have you worked in Wilton before?
Yes. Our records show 4 completed roofs in Wilton. That count comes from our own job history.
Is ice barrier required on a Wilton 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 30 psf ground snow load in Wilton, that detail is doing real work.
Do I need a permit to replace a roof in Wilton?
Yes. A roof replacement in Wilton requires a building permit, and we pull it as part of the job. The building department's published number is 203-563-0177 if you want to confirm anything independently.
What wind speed does a roof in Wilton have to be designed for?
The 2022 Connecticut State Building Code assigns Wilton an ultimate design wind speed of 120 mph. That figure sets the fastener schedule and the manufacturer wind rating we specify.
Does Wilton get hail?
Yes, though it is not the main risk here. NOAA has 1 confirmed hail report within ten miles of Wilton since 2015, the largest 1 inch across. Hail that size bruises shingles and knocks granules loose rather than punching holes, so the damage is easy to miss from the ground and worth a proper look after a summer storm.
Are ice dams a problem in Wilton?
They are the winter problem worth planning for. The nearest long-record station averages 34 inches of snow a year across about 10 days that leave an inch or more, and roughly 119 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.
