Roofing in Cupertino, CA

Serving Cupertino and Surrounding Areas

Cupertino roofs fail in predictable ways. The summer sun bakes asphalt shingles until they curl and crack, letting water seep through the granules. Then winter storms hit—sometimes dumping inches of rain in a day—and that water wicks along the decking, rotting the wood from underneath. We see the same end-of-life wear on homes near Stevens Creek Reservoir and in the hills above Vallco: sagging rooflines, peeling flashing, and shingles that flake apart in your hand.

Moss and algae don’t thrive here like they do in wetter climates, but the fog keeps the north side of many roofs damp enough for growth. That moisture erodes the granules faster and can spall the surface of concrete tiles. If you’ve noticed a drip in your attic after rain, or a stain spreading on your ceiling, don’t wait. The longer water sits, the more it decays the structure. We’ll inspect, find the source, and fix it before it becomes a replacement job.
