Our work in Durham
We have completed one roof in Durham. One job, not a portfolio — we would rather say so than dress it up. The town is 37 miles from our base in Bethel.
The town runs to 23.7 square miles, in Middlesex County.
Durham takes in Durham Center. Age and construction of the housing changes between them, which is why we look before quoting.
Design criteria for a Durham roof
Appendix AY of the 2022 Connecticut State Building Code puts Durham at an ultimate design wind speed of 120 mph, a nominal design wind speed of 93 mph. Statewide, 147 municipalities carry an equal or higher rating. As in every Connecticut town, a tear-off here triggers the sealed roof deck rule.
The code assigns Durham 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 57.7% of Durham homes predate 1980 - the median was built around 1976 - so plank decking and older fastening turn up regularly on tear-offs in this town.
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.
Durham weather, measured
Weather is what wears a roof out, so the local numbers are worth knowing. NOAA's 1991-2020 normals, taken about 26 miles from the center of town at Burlington, are the closest measured picture there is.
Snow: that station averages 39 inches a year, which is about average for this part of the state. It falls across roughly 10 days that leave an inch or more, and 5 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 142 nights a year below freezing, and 27 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: 54 inches a year there, including about 15 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.

The storms Durham has had since 2015
Rather than talk about storms in general, here is the count of confirmed severe-weather reports within ten miles of Durham across 2015-2026, straight from NOAA's Storm Events Database.
25 damaging-wind reports, the strongest put at 70 mph. Wind damage is cumulative. Each gust that lifts a tab breaks a little more of the seal underneath, and the roof that survives five storms can fail in the sixth.
7 hail reports, the largest 1.5 inches across - about the size of a ping-pong ball. Stones that big do more than bruise. They crack tabs and drive the granules off in patches, and the damage is often visible from the ground once you know the pattern.
Also on the record: the National Weather Service logged 29 winter-storm, heavy-snow or ice-storm events for Middlesex County over the same years.
After a storm like those, the sensible move is a look at the roof before anything leaks - we do that for free in Durham, and you get the photographs either way. If there is damage, our storm damage report puts the photos, measurements and a written estimate in one place for your insurer.

Permits and inspections in Durham
Durham issues roofing permits through its building department. The building official on record is Matthew Meeker. The office is staffed part-time, which is worth planning around — inspection windows are narrower than in a full-time department, and a tear-off scheduled without checking availability can sit open longer than anyone wants. The published number is 860-349-8253. Written questions go to mmeeker@townofdurhamct.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.
When Durham's houses were built
Two brackets account for most of Durham's housing. By the Census Bureau's 2019-2023 estimates, 35.6 percent of the town's 3,080 units were built between 1960 and 1979 and 33 percent between 1980 and 1999, both above Connecticut's 26.7 and 20.5 percent. The oldest and newest housing are thin by comparison: 9.3 percent before 1940, and the same 9.3 percent since 2000. The median year built is 1976, a little later than the 1972 median for the Lower Connecticut River Valley Planning Region, and the typical Durham home is about 50 years old. Nearly all of it is detached and owner-occupied. Single-family detached houses make up 93.7 percent of units, and of 3,038 occupied homes, 2,788 are lived in by their owners, a rate of 91.8 percent. For the state the same two figures are 58.7 and 66.2 percent, and for the planning region 71.8 and 75.2.
A house that age has likely outlasted any asphalt roof it was built with. InterNACHI's chart puts 3-tab shingles at 20 years and architectural shingles at 30, so the houses from 1960 to 1979 have probably been through at least one replacement, and many from 1980 to 1999 are on their second roof or close to needing one. For owners who plan to stay put, the gap between those two figures is worth weighing when the next roof is chosen.
That history makes the layer count the first thing to establish on a Durham job. A house re-roofed once by overlay already carries two applications, and R908.3.1.1 prohibits a third; every layer comes off to the deck instead. The limit counts applications of any type of covering, so a second layer of a different material still counts as a second layer.
Tear-off is also when a chimney can be dealt with properly. Under R1003.20, a chimney whose side parallel to the ridgeline measures more than 30 inches, and which does not intersect the ridgeline, needs a cricket. If an older roof went on without one, a full replacement with the deck exposed is the sensible moment to build it, rather than working around the chimney one more time.

How Durham compares with the towns around it
Every town Durham borders is rated for equal or stronger wind. Crossing the town line here means a heavier fastening schedule, not a lighter one.

Common questions about roofing in Durham
What wind speed does a roof in Durham have to be designed for?
The 2022 Connecticut State Building Code assigns Durham 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 Durham?
Yes. A roof replacement in Durham requires a building permit, and we pull it as part of the job. The building department's published number is 860-349-8253 if you want to confirm anything independently.
How many nails per shingle should be used in Durham?
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 Durham?
Matthew Meeker is the building official on record for Durham, 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 Durham 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 Durham, that detail is doing real work.
Have you worked in Durham before?
Yes. Our records show 1 completed roof in Durham. That count comes from our own job history.
Does Durham get hail?
Yes, and it is worth taking seriously. NOAA has 7 confirmed hail reports within ten miles of Durham since 2015, the largest 1.5 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 Durham?
They are the winter problem worth planning for. The nearest long-record station averages 39 inches of snow a year across about 10 days that leave an inch or more, and roughly 142 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.
