Clearlake Roofing & Maintenance has been installing asphalt shingle roofs across Clearlake for 16 years. GAF Timberline HDZ, Owens Corning Duration, CertainTeed Landmark — we carry the top shingle lines and we're certified by the manufacturers to install them.
We install every shingle roof to manufacturer specifications. That means 4-6 nails per shingle in the designated nailing zone, proper offset between courses, starter strips along the eave, and ridge cap shingles at every hip and ridge. When the manufacturer inspector shows up, your roof passes.
Our Shingle Roofing Process
Shingle Selection
Free on-site inspection. We measure, assess your roof deck condition, and walk you through architectural vs. three-tab shingles with realistic pricing. No pressure, just facts.
Old Roof Removal
We strip the old shingles, underlayment, and damaged flashing down to the roof deck. Every square foot of OSB or plywood sheathing inspected for rot, water damage, and soft spots. Compromised decking replaced before new materials go down.
Waterproofing Layer
Synthetic underlayment across the full roof deck. Ice-and-water shield in valleys, along eaves, and around chimney flashing, pipe boots, and vent boots. New drip edge installed at every eave and rake. Step flashing and counter-flashing at all wall transitions.
Shingle Installation
Starter strips along the eave, then field courses of architectural shingles with manufacturer-specified offset and overlap. Each shingle nailed in the designated zone with 4-6 fasteners. Ridge cap shingles hand-nailed at every hip and ridge for a finished, watertight top.
