Monterey Roofing & Maintenance has been installing asphalt shingle roofs across Monterey 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.
Architectural shingles are heavier and more wind-resistant than three-tab because of their laminated, multi-layer construction. The fiberglass mat provides the structural base, asphalt makes it waterproof, and the granulated ceramic surface protects against UV radiation and provides fire resistance. We install them over synthetic underlayment with ice-and-water shield at valleys and eaves.
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
Full tear-off to the deck. Old shingles, deteriorated felt, and corroded flashing removed and hauled to the dumpster. Deck inspection catches hidden damage — rotted sheathing, water-stained OSB, nail pops — before it's buried under new shingles.
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.
Nailing & Overlap
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.
