Flat roofs in San Francisco usually leak at seams, parapet walls, drains and scuppers, and ponding water makes every weak point worse. Water that sits on a roof for days after rain stresses seams, feeds algae and finds pinholes. The lasting fix is to restore drainage, with tapered insulation, crickets or better drains, and repair or replace the membrane.

Architectural shingles are thicker, laminated, multi-layer shingles with a dimensional look; 3-tab shingles are a single flat layer cut into three tabs. Architectural shingles generally carry higher wind ratings and longer manufacturer warranties, and they hide minor deck unevenness better. For most Bay Area reroofs today, architectural is the default choice.

Roof valleys leak because they carry water from two roof planes at once, so any weakness shows up first there. Common causes are debris dams, worn shingles in the valley center, nails driven too close to the valley, missing valley underlayment and corroded metal. Small damage can be repaired; a worn-out valley should be rebuilt.

A leaking skylight is usually failing in one of three places: the flashing where it meets the roof, the seal between the glass or dome and the frame, or a cracked lens. Condensation can look like a leak too. Flashing problems call for reflashing; a failed seal or cracked unit on an older skylight usually means replacement.

Synthetic underlayment is a woven or spun polymer sheet that replaces traditional asphalt felt under shingles, tile, or metal. It is lighter, much stronger against tearing, more slip-resistant to walk on, and handles a few days of weather exposure better. For most Bay Area reroofs it is the better choice, paired with self-adhered membrane at valleys and penetrations.

A reroof final inspection confirms the finished roof matches the permit. The inspector typically checks the roofing product and its fire or cool-roof rating where required, flashing at walls, chimneys and valleys, drip edge, ventilation, fastening, and that the permit card and paperwork are on site. Passing it closes the permit on record.

Most chimney leaks come from failed flashing where the roof meets the brick: step flashing and counter flashing that have pulled loose, rusted, or were only sealed with caulk. Cracked crowns, porous brick and missing crickets on wide chimneys cause the rest. A lasting fix replaces the flashing system, not just the sealant.

A quality roof system has seven working layers: a sound wood deck, underlayment, self-adhered membrane at eaves, valleys and penetrations, metal drip edge, a starter course, the shingles or other covering, and flashing plus ventilation. Most leaks start where one of these hidden parts was skipped, not in the visible shingles.
