A full roof replacement means stripping the old roofing material down to the deck, repairing or replacing any damaged sheathing, installing new underlayment and flashing, and laying new shingles, metal, tile, or another roofing system on top. It's a bigger job than a repair or a recover: crews typically work on it for one to three days depending on the size and pitch of the house, and it touches nearly every part of the roof system at once, including vents, valleys, and edge details around chimneys and skylights. In West Haven, that also means dealing with coastal humidity and salt air, which is why flashing quality and ventilation matter as much as the shingle brand.
What to look for in a roofer
Price matters, but it shouldn't be the only thing you compare. Before you sign a contract, check that the contractor is licensed and insured in Connecticut, ask whether they pull a building permit (a re-roof almost always requires one here), and get the manufacturer certification level if they're installing a brand-name shingle system, since that affects your warranty coverage. A written estimate should break out tear-off, disposal, decking repair (often billed separately if rot is found), underlayment, flashing, and labor, not just a lump sum. Ask how they handle unexpected deck damage and whether ice-and-water shield is included at eaves and valleys, since that detail matters a lot for New England winters.
