Storm Damage Repair
Wind damage and hail damage look different and require different documentation. Our HAAG-trained inspectors know what adjusters look for: granule displacement patterns, fractures in the shingle mat, seal failures, cracked ridge caps. Proper documentation is why our claims get approved.

New Roof Installation
New construction roofing in San Jose starts with getting the design details right before materials arrive. Roof pitch, attic ventilation needs, snow load requirements, and local code amendments all affect material selection and installation methods. We coordinate with your general contractor or architect to ensure the roof system matches the building specifications.

Metal Roofing
Corrugated metal and R-panel (exposed fastener) at $5-$8/sq ft installed for agricultural buildings, shops, carports, and covered patios in San Jose. 29-gauge is budget, 26-gauge is standard. For residential, we recommend 24-gauge standing seam at $12-$22/sq ft. The aesthetics and longevity justify the premium. DaVinci composite shake and slate profiles offer the look of natural materials with metal's performance. Perfect for San Jose HOA neighborhoods that restrict metal roofing appearance.

Shingle Roofing
Asphalt shingles cover more homes in America than every other roofing material combined. There's a reason. They're affordable, they look good, they last 25-50 years depending on the grade, and they come in dozens of colors and profiles. Our San Jose crews have installed thousands of shingle roofs and we know the product better than most roofers in the state.

Flat Roofing
Flat roofs don't actually drain themselves. That's the challenge. Water ponds, UV breaks down the membrane, and eventually it leaks. We install and repair TPO, PVC, EPDM, modified bitumen, and built-up roofing systems designed for zero-slope conditions in San Jose.

Commercial Roofing
Multi-family properties in San Jose need roofing contractors who understand occupied buildings. We schedule around tenants, contain debris, and minimize noise during reasonable hours. Emergency leak repairs get priority. Water in someone's apartment is an emergency.

Gutter Installation
Seamless aluminum in 5" K-style is the standard for San Jose residential. We use 6" K-style on larger homes, steeper pitches, or roof areas with high water volume. Downspouts are 2x3" on 5" gutters and 3x4" on 6" gutters. Matched to handle the flow.

Roof Inspection
We don't inspect roofs from the ground with binoculars. We get on the roof. Every inspection includes a full walkthrough: shingle condition, flashing integrity, pipe boots, ridge vent, soffit ventilation, gutter function, and visible attic moisture signs. You get photos and a written report.

Skylight Installation
Replacing an old leaking skylight is often cheaper than trying to repair it. New units from VELUX have Low-E laminated glass, argon fill, and No Leak guarantees when installed with the manufacturer's flashing system. Our San Jose crews replace skylights in a single day.
