Our work in Ansonia
We have completed one roof in Ansonia. One job, not a portfolio — we would rather say so than dress it up. The town is 17 miles from our base in Bethel.
Ansonia covers 6.0 square miles in New Haven County.
Design criteria for an Ansonia roof
Roofs in Ansonia 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 amendment to R905.1.1 applies statewide, so a full tear-off here brings the sealed roof deck requirement with it.
Ground snow load in Ansonia 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
Two Connecticut amendments matter on almost every job. The first is statewide ice barrier, R905.1.2: from the lowest edge of the roof to a point 24 inches or more inside the exterior wall line, measured on the slope. On a shallow pitch that is a surprising amount of membrane. The second is R905.1.1, the sealed roof deck rule, which has an exception for lumber sheathing of less than 3 feet nominal width — common on older housing stock here.
That decking exception is not a footnote in Ansonia: 85% of the housing here went up before 1980 and 34.9% before 1940, so plank decking under the shingles is the rule rather than the exception.
Four is code, six is warranty. Connecticut's minimum is four nails per shingle; the shingle manufacturers want six before they will stand behind a wind claim. We use six. What we will not do is tell you the state requires it, because it does not.
The climate a roof in Ansonia has to take
Thirty years of readings from the nearest long-record station, about 13 miles from the center of town at Igor I Sikorsky Mem Ap, say more about what an Ansonia roof faces than any brochure does. These are NOAA's 1991-2020 normals.
Snow: that station averages 34 inches a year, which is on the lighter side for this part of the state. It falls across roughly 9 days that leave an inch or more, and 4 that leave three inches or more. None of it matters on a roof that is vented with its eaves protected. On one that is not, the thaw is what gets inside - water backing up under the courses from a dam of ice at the gutter line.
Freeze-thaw: the station records about 92 nights a year below freezing, and 18 days never climb above it. Every one of those nights is a cycle for any water sitting in a lifted seam, an open flashing joint or a nail hole. Water expands as it freezes, the gap widens, and next time it holds more water. That cycle, not sunlight, is what finishes off flashing and old sealant in Connecticut.
Rain: 44 inches a year there, including about 10 days when an inch or more falls in a single day and 2 that top two inches. That much water finds every shortcut: valleys that were never properly lined, gutters too small for the roof above them, and the missing kick-out flashing where a roof edge meets a wall.

What the storm record says about Ansonia
There is a public record of severe weather, town by town. For the ten miles around Ansonia, this is what NOAA confirmed across 2015-2026.
66 damaging-wind reports, the strongest put at 81 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.
4 hail reports, the largest 1 inch across - about the size of a quarter. Stones in that range knock granules loose and bruise the mat below. Nothing looks broken, but the clock on the roof speeds up.
Also on the record: 3 confirmed tornadoes touched down inside the same circle and the National Weather Service logged 30 winter-storm, heavy-snow or ice-storm events for New Haven 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 Ansonia - 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 Ansonia
Permits for roof work in Ansonia go through the town building department. Nick Behun is listed as the building official. Staffing is part-time, so inspection slots are limited. We book around them rather than hoping. The published number is 203-736-5960. Written questions go to kfranco@ansoniact.org. Permitting is on us, not on you. A contractor asking a homeowner to pull the roofing permit is shifting liability, and you should treat it that way.
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.
Ansonia's houses are older, and more often multi-family, than Connecticut's
Census Bureau estimates for 2019-2023 put the median year built in Ansonia at 1954. Connecticut's median is 1967 and the Naugatuck Valley Planning Region's is 1969, so the typical Ansonia home is about 72 years old in 2026, where the typical Connecticut home is about 59. The breakdown by era says the same thing: 34.9 percent of the town's 8,389 housing units went up before 1940, another 27.5 percent between 1940 and 1959, and only 6.5 percent since 2000. In all, 85 percent predate 1980, against 67.7 percent statewide.
The buildings differ as well. Single-family detached houses are 47.2 percent of units here and 58.7 percent across the state, while buildings of two to four units hold 37.3 percent, against 16 percent statewide. Owners occupy 58.6 percent of occupied homes and renters 41.4 percent, so a good number of Ansonia roofs keep tenants dry as well as the people who pay for them.
On the roof, age drives nearly everything else. InterNACHI's life expectancy chart gives 3-tab asphalt about 20 years and architectural shingles about 30, so a house of the median age has probably worn through more than one covering already. That history shows up at tear-off. If an earlier roofer laid new shingles over old ones, the house may now carry two layers, and IRC R908.3.1.1 does not allow a third to go on top; the same section bars covering an existing slate roof at all. Metal gets the same scrutiny. Under R908.5, flashings, edgings and vents that are rusted, damaged or deteriorated are replaced, not reused, which on an older house can mean new chimney and wall flashing along with the shingles.
Painted wood is the last consideration. Built before 1980, the bracket that holds 85 percent of Ansonia's units, is the nearest Census cutoff to 1978, the line for target housing in EPA's Renovation, Repair and Painting rule, which reaches housing built before that year, with some exceptions. Paid work on pre-1978 homes that disturbs painted fascia, soffit or trim falls under the rule once it passes 20 square feet on the exterior, and window replacement or demolition of painted surfaces gets no small-job exclusion at all.

How Ansonia compares with the towns around it
Ansonia shares its design wind figure with all 3 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. Ansonia | Ground snow | County |
|---|---|---|---|---|
| Derby | 120 mph | same | 30 psf | New Haven |
| Seymour | 120 mph | same | 30 psf | New Haven |
| Woodbridge | 120 mph | same | 30 psf | New Haven |

Common questions about roofing in Ansonia
Who is the building official in Ansonia?
Nick Behun is the building official on record for Ansonia, per the State of Connecticut list of municipal building officials. Staffing changes — confirm with the town before relying on it.
Have you worked in Ansonia before?
Yes. Our records show 1 completed roof in Ansonia. That count comes from our own job history.
Is ice barrier required on an Ansonia 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 Ansonia, that detail is doing real work.
Do I need a permit to replace a roof in Ansonia?
Yes. A roof replacement in Ansonia requires a building permit, and we pull it as part of the job. The building department's published number is 203-736-5960 if you want to confirm anything independently.
How many nails per shingle should be used in Ansonia?
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 Ansonia have to be designed for?
The 2022 Connecticut State Building Code assigns Ansonia an ultimate design wind speed of 120 mph. That figure sets the fastener schedule and the manufacturer wind rating we specify.
Does Ansonia get hail?
Yes, though it is not the main risk here. NOAA has 4 confirmed hail reports within ten miles of Ansonia 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 Ansonia?
They are the winter problem worth planning for. The nearest long-record station averages 34 inches of snow a year across about 9 days that leave an inch or more, and roughly 92 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.
