Roof Replacement in San Jose, CA

A full roof replacement starts with a complete tear-off. We remove every shingle, nail, and piece of debris down to the roof deck—the structural layer of OSB or plywood that holds everything together. Once exposed, we inspect the deck for rot, sag, or structural damage. If the sheathing is compromised, we replace damaged sections before moving forward. This step catches problems that patch jobs miss.

Next comes the underlayment—a synthetic barrier that sits between the deck and your new shingles. We install ice-and-water shield in valleys and along the eaves, where snow melt and rain penetration happen first. The drip edge—a metal trim—guides water away from fascia and soffit. Ridge vents run along the peak to exhale heat and moisture; proper ventilation extends shingle life by years. We install architectural shingles using a nail gun, setting each fastener at the manufacturer's specification—one mistake per shingle costs you leaks later. Flashing seals pipes, valleys, and transitions. Ridge cap shingles finish the peak. A dumpster hauls debris. The whole job typically takes 2 to 3 days, depending on roof size and complexity.

Cost ranges from $8,000 to $18,000 for a typical San Jose home, depending on square footage, pitch, and material choice. GAF Timberline, Owens Corning Duration, and CertainTeed Landmark are solid mid-range picks. Your new roof comes with a manufacturer warranty—often 20 to 30 years—and we handle the registration. Building code compliance is non-negotiable; every roof must meet current standards for wind resistance and load capacity.
