Step flashing at chimney walls is the number one leak source we see in American Canyon. Improper step flashing causes roof leaks. It's that simple. We install new step flashing with a chimney cricket for proper water diversion, sealed with Geocel tripolymer sealant. Fix it once, fix it right.

Wind damage doesn't always look obvious from the ground. Lifted shingles, broken seals, exposed nail heads. You can't see any of that without getting on the roof. Our American Canyon inspector does a full 27-point inspection, free of charge.

New construction roof installation following IRC Section R905 and local American Canyon building code amendments. We calculate ventilation per IRC R806 (1:150 ratio reduced to 1:300 when 50% is within 3ft of ridge. Synthetic underlayment per ASTM D226, ice barrier per ASTM D1970 at eaves in freeze-thaw climate zones. Manufacturer-certified installation locks in the full system warranty.

Standard 5" K-style handles 5,520 sq ft of effective roof area. Bigger roofs or steeper pitches need 6" gutters with 3x4" downspouts. We hang with hidden hangers screwed into rafter tails every 24".

Emergency tarping is the first priority. We cover the exposed area to stop water entry, then schedule the permanent repair once conditions allow. We don't charge extra for emergency tarp jobs. It's part of the repair cost.

A skylight installed wrong will leak. The flashing has to integrate with the shingle courses. Step flashing on the sides, headwall flashing on top, and a sill pan underneath. We use manufacturer flashing kits because they're engineered to work with the skylight frame.
