Roofing Services in San Francisco
The Mission District packs more rooflines per block than almost anywhere in San Francisco. Edwardian homes from the 1900–1920 rebuild crowd against post-1906 survivors, mid-century apartment infill, and the occasional Victorian holdout. That mix means no two jobs look alike, and the steep slopes and bay windows demand a roofer who reads a roofline like a local.
San Ramon Roof Repair works throughout San Francisco, but the Mission is where our crew feels most at home. The dense grid, the fog rolling over Liberty Hill, the way Dolores Park catches the afternoon sun—we know how these conditions beat on a roof. Frequent marine-layer moisture seeps into aging flashing. Strong Pacific storms test every exposed fastener. And those bay window dormer valleys? They leak when the waterproofing fails, and on these classic rowhouses, it often has.
Our approach starts with a tear-off when the old layers have reached end-of-life wear. We've seen original cedar shingles suffering granule loss and wind uplift, composition shingles curling and splitting, and flat sections over garages that pond water because the drainage was never right. We fix that with self-adhered underlayment, ring-shank nails, and proper starter course and field course installation. Staggered courses keep water moving downhill, not into your living room.
We also respect the Mission Dolores Neighborhood Conservation District. If your roof is visible from the street, we'll help you navigate the review process before we start. No surprises, no fines—just a roof that passes inspection and looks right on the block.
Whether it's a full roof replacement on a steep Edwardian slope or a membrane repair on a low-slope addition, we mend, restore, and maintain with the same straightforward care. Call 9257239025 for a free estimate, or check out our roof repair services to see what we handle.
Common Roof Problems in San Francisco
Steep-slope roofs on Mission District Edwardians often still carry original cedar shingles or early composition shingles. After decades of fog and sun, they suffer granule loss, curl, and split. Then a strong Pacific storm hits, and wind uplift peels shingles off the starter course like paper. That's when water finds its way in.
Bay windows and dormer valleys on these rowhouses are another trouble spot. Aging flashing and inadequate waterproofing let rain seep behind the siding, wick along the decking, and rot the framing from the inside out. You might not notice until the ceiling stains or the paint starts to peel.
Flat or low-slope sections over additions and garages are common too. Old membranes blister, flake, and eventually crack. Without proper drainage, water ponds and erodes the substrate. We replace those membranes with modern self-adhered systems that handle the marine-layer moisture and heavy rain years.
And if your home sits in the Mission Dolores Neighborhood Conservation District, any visible exterior change needs review. We'll flag that before we start, so your roof repair doesn't stall on a permit issue.
