Roof replacement means tearing off the old roofing material down to the deck (or in some cases overlaying it, though tear-offs are the more durable choice) and installing new underlayment, flashing, and a new roof surface, most often asphalt shingles in New Haven's housing stock, but also standing-seam metal, slate on older homes near the historic districts, or flat/rubber membrane (EPDM or TPO) on additions and low-slope sections common on triple-deckers. It's a bigger job than a repair: expect a crew on site for one to three days for a typical single-family home, dumpster or trailer for tear-off debris, and a permit pulled with the City of New Haven's building department. We've identified 14 roof replacement and installation contractors serving the area, ranging from small local crews to larger regional outfits.
Before hiring, ask for proof of Connecticut contractor registration and current liability and workers' comp insurance, a written estimate that spells out materials (shingle brand and class, underlayment type, ice-and-water shield at eaves and valleys), and a manufacturer-backed warranty in addition to the contractor's own labor warranty. Get at least two or three bids, since pricing and scope can vary widely for what sounds like the same job, and ask how they handle unexpected deck rot found during tear-off, since that's the most common source of change orders.
Our scores weigh verified licensing and insurance, customer feedback, responsiveness, and consistency of work over time, so you can compare these 14 businesses on more than just price.
