A full roof replacement means stripping the existing shingles or roofing material down to the deck, checking that plywood or OSB sheathing for rot or soft spots, replacing what's damaged, installing new underlayment and flashing around chimneys, vents and valleys, then laying the new roof covering. For most West Haven homes that's asphalt shingles, though some contractors also handle metal, slate repair-matching, or flat roofing on additions and porches. It's a bigger job than a patch repair: expect a crew on site for one to three days depending on roof size and complexity, plus dumpster delivery for the tear-off debris.
We list 13 roof replacement and installation contractors serving West Haven. Before hiring, look for a written estimate that breaks out materials, labor, disposal and any deck repair as a separate line item, proof of Connecticut licensing and liability insurance, and a clear warranty on both materials and workmanship. Ask whether they pull the required town permit themselves, since a permitted job means an inspector signs off on the work.
Our scoring weighs verified reviews, how consistently a contractor shows up and follows through, and signals like licensing and business longevity, so you're not just going on star ratings alone.
