If you need a new shingle roof in Port Costa, here's what matters: fiberglass mat construction with ceramic granulated coating for UV protection and fire rating. Architectural shingles carry a Class A fire rating and wind resistance ratings up to 130 mph. Port Costa Roofing & Maintenance helps you pick the right shingle for your home and budget.
The difference between a 15-year roof and a 30-year roof isn't the shingle — it's the installation. Proper nail placement in the manufacturer's nailing zone, correct overlap between courses, ice-and-water shield at all vulnerable areas, and flashing that's sealed at every transition. Port Costa Roofing & Maintenance follows the exact specs that keep the manufacturer warranty valid.
Our Shingle Roofing Process
Free Roof Estimate
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.
Underlayment & Flashing
Ice-and-water shield bonded at valleys and eave lines. Synthetic underlayment over the full deck. New aluminum drip edge at every eave and rake. All flashing — chimney, pipe, vent, wall — sealed and secured before a single shingle goes down.
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.
