Tomales Roofing & Maintenance has been installing asphalt shingle roofs across Tomales for 23 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
Free Roof Estimate
Our estimator examines your current roofline, checks the condition of the underlayment and flashing, and presents shingle options with honest pricing. GAF, Owens Corning, CertainTeed — you pick.
Strip & Inspect
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.
Ice Shield & Drip Edge
The waterproofing layer is what protects your home if a shingle ever fails. We install ice-and-water shield at every vulnerable point — valleys, eaves, penetrations — then roll synthetic underlayment over the entire deck. Drip edge directs water into gutters, not behind fascia boards.
Shingle Courses
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.
