The moment a nor'easter peels back an asphalt shingle or a limb punches through the roof deck, water works along the underlayment and into the attic. We tarp first, photograph everything, and only then talk through the permanent fix.
Replacement shingles have to match the slope you already own, whether that's three-tab, architectural shingle, wood shake, or cedar shake. On slate, clay tile, and concrete tile roofs, the repair is usually flashing and sealant work rather than a full tear-off.
Flat sections get a membrane — TPO, EPDM, or a PVC membrane — while older buildings with a built-up roof or modified bitumen need a patch sized to the existing lap. Felt, tar paper, and synthetic underlayment all wick differently, so we check before sealing.
