Design criteria for a Harwinton roof
The state assigns Harwinton an ultimate design wind speed of 120 mph — 93 mph nominal — in Appendix AY of the 2022 Connecticut building code. 148 of Connecticut's 169 municipalities are rated at or above that figure. As in every Connecticut town, a tear-off here triggers the sealed roof deck rule.
The code assigns Harwinton a ground snow load of 35 psf. It is a middle figure for Connecticut, and the practical effect is concentrated at the details rather than the field.
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 67.7% of Harwinton homes predate 1980 - the median was built around 1965 - so plank decking and older fastening turn up regularly on tear-offs in this town.
On nailing, be careful who you believe. Connecticut's code minimum is four nails per shingle. Six is what the shingle manufacturers require to keep a wind warranty in force, and six is what we install — but that is a manufacturer requirement, not a code requirement. A contractor telling you the code demands six is either mistaken or selling.
What the weather does to roofs in Harwinton
Roofs are worn out by weather, not by time. The measured picture for Harwinton comes from the long-record station about 6 miles from the center of town at Bakersville, over the thirty years behind NOAA's 1991-2020 normals.
Snow: 59 inches in an average year, which is a heavy-snow town by Connecticut standards. It falls across roughly 15 days that leave an inch or more, and 7 that leave three inches or more. Weight is seldom the issue on a roof that is sound. Meltwater is: it runs to the cold overhang, freezes there, and the next thaw has nowhere to go but sideways, under the shingles.
Freeze-thaw: about 158 nights a year drop below freezing, and 35 days never climb above it. Freezing water expands with enough force to widen any gap it is sitting in. Do that on most nights of the winter and the sealant around a chimney or a vent pipe gives up years before the shingles do.
Rain: 54 inches a year, including about 15 days when an inch or more falls in a single day and 3 that top two inches. Water at that rate does not soak in, it runs, and where it runs is the test of the valleys, the gutters and the flashing where the roof meets a wall.
Harwinton sits around 685 feet above sea level, which matters because snow totals and freeze-thaw counts both climb with elevation in Connecticut.

Harwinton's storm record, from the National Weather Service
What has Harwinton actually been hit by? NOAA's Storm Events Database, 2015-2026, within ten miles of the center of town, says this.
90 damaging-wind reports, the strongest put at 90 mph. That is the number that matters most here. Wind damage starts at the edges and the ridge, and it rarely shows itself from the driveway.
6 hail reports, the largest 1.25 inches across - about the size of a half dollar. That is past the bruising range. Hail of that size splits the mat under the granules, and a split mat lets water into the shingle itself.
Also on the record: 1 confirmed tornado touched down inside the same circle and the National Weather Service logged 22 winter-storm, heavy-snow or ice-storm events for Litchfield County over the same years.
A storm record is not a damage report. The only way to know is to look, which costs nothing in Harwinton - and you keep the photographs whether or not there is anything to find. If there is, the storm damage report puts the evidence in one place.

Permits and inspections in Harwinton
Roofing work in Harwinton is permitted through the town's building department. The building official on record is Nicholas Canny. It is a part-time office. That is not a criticism, it is a scheduling fact: we confirm inspection availability before we open a roof here. The published number is 860-485-3892. Written questions go to building@harwinton.us. 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.
Harwinton's houses, their owners, and their age
Nearly every occupied home in Harwinton is lived in by its owner: 91.5 percent, according to the Census Bureau's 2019–2023 estimates, against 66.2 percent across Connecticut and 75.9 percent in the Northwest Hills Planning Region. Single-family detached houses make up 94.4 percent of the town's 2,309 units.
So roof decisions here are mostly made by the people who live under the roof, and the houses are old enough that many of those decisions are replacements. Harwinton's median year built is 1965, putting the typical house at about 61 years old in 2026. The estimates place 30.1 percent of units in the years 1940 to 1959, against 20.7 percent statewide, and 67.7 percent before 1980, the same share as Connecticut's. Only 10.5 percent were built in 2000 or later. The region is older at the far end, with 27.8 percent of units built before 1940 against Harwinton's 13.6, but the town's median sits close to the region's 1966.
At that age the first roof is very likely long gone; InterNACHI puts 3-tab asphalt at 20 years and architectural at 30. When a Harwinton roof is replaced, IRC R908.3 as adopted in Connecticut calls for taking the existing layers off down to the roof deck, so the condition of a deck that has likely sat under more than one roof becomes part of the job. Smaller work is treated differently: under the state's amended R105.2, repairs limited to 25 percent of the roof covering in a calendar year need no permit. The 21.8 percent of houses from 1980 to 1999 carry a different risk: if their second roof went over the first, IRC R908.3.1.1 bars a third layer, and the next job is a tear-off whatever the shingles look like.
The pre-1980 majority also takes in the pre-1978 houses that EPA counts as target housing. The agency's Renovation, Repair and Painting rule covers paid jobs that disturb painted surfaces on them, with a minor-repair exclusion for exterior work disturbing 20 square feet or less of paint; window replacement and demolition of painted surfaces do not qualify for that exclusion.

Common questions about roofing in Harwinton
Is ice barrier required on a Harwinton 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 35 psf ground snow load in Harwinton, that detail is doing real work.
Have you worked in Harwinton before?
Yes. Our records show 2 completed roofs in Harwinton. That count comes from our own job history.
Who is the building official in Harwinton?
Nicholas Canny is the building official on record for Harwinton, 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 Harwinton?
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.
What wind speed does a roof in Harwinton have to be designed for?
The 2022 Connecticut State Building Code assigns Harwinton 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 Harwinton?
Yes. A roof replacement in Harwinton requires a building permit, and we pull it as part of the job. The building department's published number is 860-485-3892 if you want to confirm anything independently.
Does Harwinton get hail?
Yes, though it is not the main risk here. NOAA has 6 confirmed hail reports within ten miles of Harwinton since 2015, the largest 1.25 inches across. Stones that size crack the mat under the granules rather than just bruising it, so the damage is real even when the roof looks sound from the driveway.
Are ice dams a problem in Harwinton?
They are the winter problem worth planning for. The nearest long-record station averages 59 inches of snow a year across about 15 days that leave an inch or more, and roughly 158 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.
