Our work in Westport

Our records show 11 roofs finished in Westport. It is 18 miles from Bethel.

Westport is a 20.0-square-mile municipality in Fairfield County. It is one of Connecticut's 24 shoreline municipalities. Salt air is hard on fasteners and on the metal at valleys, drip edge and flashing, which is why we specify stainless or heavier coatings nearer the water than we would inland.

Neighborhoods and villages here include Coley Town, Coleytown, Compo, Greens Farms, Hale Court, Old Hill, Owenoke, Poplar Plains, Saugatuck, Saugatuck Shores, Staples and Westport Village. What is on the roofs differs across them, and so does what should go back on.

Design criteria for a Westport roof

Roofs in Westport 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. Statewide, 147 municipalities carry an equal or higher rating. Connecticut's amended R905.1.1 applies statewide, so the sealed roof deck requirement is triggered on a full tear-off here.

The code assigns Westport a ground snow load of 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.

It matters here because 61.4% of Westport homes predate 1980 - the median was built around 1968 - 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.

The weather a Westport roof lives with

Roofs are worn out by weather, not by time. The measured picture for Westport comes from the long-record station about 11 miles from the center of town at Stamford 5 N, over the thirty years behind 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 10 days that leave an inch or more, and 4 that leave three inches or more. A sound roof carries the weight without complaint. The damage comes from melt-and-refreeze at the eaves, where backed-up water gets under the shingles. The eave detail is where a re-roof here is won or lost.

Freeze-thaw: the station records about 119 nights a year below freezing, and 16 days never climb above it. That is a hundred-odd chances a year for trapped water to freeze, expand and open a joint a little wider. It is why flashing and sealant age faster here than the shingles above them do.

Rain: 52 inches a year there, including about 16 days when an inch or more falls in a single day and 3 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 has actually hit Westport since 2015

What has Westport actually been hit by? NOAA's Storm Events Database, 2015-2026, within ten miles of the center of town, says this.

61 damaging-wind reports, the strongest put at 70 mph. Wind is the everyday roof risk in this part of Connecticut. It lifts shingle tabs along the rakes and ridge, strips the oldest courses first, and leaves a roof that looks fine from the street.

2 hail reports, 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.

A storm record is not a damage report. The only way to know is to look, which costs nothing in Westport - 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 Westport

Westport issues roofing permits through its building department. That office is headed by Peter Howard. It is a full-time department, which usually makes inspection scheduling simple. The published number is 203-341-5025. Written questions go to phoward@westportct.gov. 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.

Westport's housing stock and what it asks of a roof

Westport is mostly a town of owner-occupied, detached houses. Census estimates put single-family detached homes at 86.8 percent of units, where the Western Connecticut Planning Region is at 57.7 percent and the state at 58.7, and 87.1 percent of occupied homes are owner-occupied. The age profile is unusual too. A full 23.1 percent of Westport's housing was built in 2000 or later, compared with 17.6 percent in the region and 11.8 percent statewide, yet the median year built is 1968, about 58 years ago, because most of the rest is older: 61.4 percent predates 1980.

What is thin is the middle. The estimates put 18.6 percent of homes before 1940, 20.8 percent from 1940 to 1959 and 22 percent from 1960 to 1979, but only 15.5 percent of Westport homes date from 1980 to 1999, below the state's 20.5 percent, so the town's roofs fall largely into two camps: houses from before 1980, most of which have likely been re-roofed at least once, and houses from 2000 on, many still on their first roof.

For the older camp, IRC R908.3 decides the scope of the next job. Connecticut adopted it as written, and it defines a roof replacement as removing the existing layers down to the roof deck, so any earlier layover comes off with the current roof. Those houses also carry a paint question. Housing built before 1978 is target housing, with some exceptions, under EPA's Renovation, Repair and Painting rule, which covers paid work that disturbs painted surfaces such as fascia and trim. Exterior work disturbing 20 square feet or less of paint is excluded, except for window replacement or demolition of painted surfaces.

For the newer camp, the first replacement is the decision point. The oldest of those original roofs have passed the 20 years that InterNACHI's life expectancy chart gives 3-tab shingles, and it lists architectural asphalt at 30, wood at 25, metal at 40 to 80 and slate at 60 to 150. Those ranges are worth having in hand when a first roof comes due, since the material chosen then sets the calendar for the decades after. Stallion Ridge backs its roofs with a 25-year workmanship warranty.

How Westport compares with the towns around it

Westport shares its design wind figure with all 4 of its neighbors, so specifications carry across these town lines cleanly. The permit process does not — each town runs its own.

Common questions about roofing in Westport

Have you worked in Westport before?

Yes. Our records show 11 completed roofs in Westport. That count comes from our own job history.

Who is the building official in Westport?

Peter Howard is the building official on record for Westport, per the State of Connecticut list of municipal building officials. Staffing changes — confirm with the town before relying on it.

Is ice barrier required on a Westport 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 Westport, that detail is doing real work.

Do I need a permit to replace a roof in Westport?

Yes. A roof replacement in Westport requires a building permit, and we pull it as part of the job. The building department's published number is 203-341-5025 if you want to confirm anything independently.

What wind speed does a roof in Westport have to be designed for?

The 2022 Connecticut State Building Code assigns Westport an ultimate design wind speed of 120 mph. That figure sets the fastener schedule and the manufacturer wind rating we specify.

How many nails per shingle should be used in Westport?

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.

Does Westport get hail?

Yes, though it is not the main risk here. NOAA has 2 confirmed hail reports within ten miles of Westport 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 Westport?

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.
