Our work in Derby
We have completed 2 roofs in Derby. That figure comes from our own job records rather than an estimate, and it moves as we work. The town is 16 miles from Bethel.
Derby covers 5.1 square miles in New Haven County.
Neighbourhoods and villages here include East Derby. What is on the roofs differs across them, and so does what should go back on.
Design criteria for a Derby roof
For Derby, the governing figure is an ultimate design wind speed of 120 mph (93 mph nominal), straight out of Appendix AY of the 2022 state code. Statewide, 147 municipalities carry an equal or higher rating. It also falls within the hurricane-prone region, so a full tear-off here brings the sealed roof deck requirement with it.
The code assigns Derby a ground snow load of 30 psf. Baseline loading for the state, which puts the emphasis on eave detailing rather than on structure.
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 inches nominal — which is exactly what many pre-1950 houses in this state have.
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.
Permits and inspections in Derby
Permits for roof work in Derby go through the town building department. Joe Ballaro is listed as the building official. Full-time staffing means inspections here rarely become the bottleneck. The published number is 203-736-1450. Written questions go to jballaro@derbyct.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.
How Derby compares with the towns around it
Derby shares its design wind figure with all 5 of its neighbours, so specifications carry across these town lines cleanly. The permit process does not — each town runs its own.

Common questions about roofing in Derby
What wind speed does a roof in Derby have to be designed for?
The 2022 Connecticut State Building Code assigns Derby 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 Derby?
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.
Is ice barrier required on a Derby 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 Derby, that detail is doing real work.
