South San Francisco Roofing & Maintenance has been installing asphalt shingle roofs across South San Francisco for 15 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.
Every shingle roof starts with the layers beneath the shingles. Synthetic underlayment rolls across the entire roof deck as the primary waterproof barrier. Ice-and-water shield goes down in the valleys, along the eaves, and around every penetration — chimney flashing, pipe boots, vent boots. Drip edge along every eave and rake directs water into the gutters instead of behind the fascia.
Our Shingle Roofing Process
Free Roof Estimate
We inspect your existing roof deck and sheathing, measure the area, and help you choose between architectural and three-tab asphalt shingles. Color samples brought to your South San Francisco home.
Tear-Off & Deck Prep
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.
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.
Nailing & Overlap
Field shingles installed with proper exposure and overlap. Nailed per manufacturer specs — 4 nails standard, 6 in high-wind zones. Starter strips at the eave prevent wind uplift. Ridge cap shingles finish every peak with integrated ridge vent for ventilation.
