Free Estimate (925) 503-1377

Roof replacement in Walnut Creek starts with a full tear-off down to the deck. We don't overlay over damaged layers—that hides rot and shortens the new roof's life. Once the deck is bare, we inspect for sag, decay, and water intrusion, replacing any compromised plywood before laying down self-adhered ice and water shield in the valleys and eaves. Then come the starter course and field course, with ring-shank nails and staggered courses for wind resistance. Most homes here are 1960s–1980s ranches and two-stories, so we're used to steep pitches and tricky rooflines that face Mount Diablo's afternoon winds. The cost depends on square footage, pitch, and material—architectural asphalt runs $8–$12 per square foot installed; metal and synthetic slate run higher. If your roof is under 15 years old with isolated leaks, repair might do. But when shingles are curling, buckling, or losing granules in the gutters, replacement is the honest answer.
