Roof installation means stripping the old covering down to the sheathing, replacing rotted plywood or OSB decking, and rebuilding the roof system from the substrate up. The old felt, tar paper, and three-tab shingle come off in a tear-off before anything new goes down.
Materials matter in this climate. We install GAF, Owens Corning, and CertainTeed architectural shingles built for hot, dry summers with occasional fire season winds, and we back the work with a 10-year workmanship warranty plus up to 50-year manufacturer coverage.
A correct install also covers what you never see: step flashing and counter-flashing at sidewalls, chimney flashing, pipe boots at every penetration, a drip edge along the eave and rake, and ridge vents that let the attic breathe. Skip those and water wicks into the roof deck fast.
