What Alviso Customers Say

★★★★★

"Their crew showed up at 7 AM, tore off the old roof, replaced eight sheets of plywood, and had new shingles down before dinner. Jobsite was cleaner when they left than when they arrived."

— Ashley S., Alviso

★★★★★

"Our flat roof on the garage had been patched five times by other companies. Castella Roofing & Maintenance stripped it and put on a proper TPO membrane. No leaks in two years. Should have called them first."

— Thomas M., Alviso

Why Alviso Residents Choose Castella Roofing & Maintenance

Manufacturer-Certified Installation

We hold certifications from GAF, Owens Corning, and CertainTeed. That means the manufacturers have trained and vetted our crews and will back our installations with their strongest warranties. Your Alviso roof gets factory-level quality control.

Licensed, Bonded & Insured

Castella Roofing & Maintenance carries full liability insurance and workers' compensation for every crew member. We're licensed across CA and pull local permits for all Alviso projects. Your property and your investment are protected.

Storm Damage Specialists

Hail, wind, and monsoon damage are common in CA. Our team includes HAAG Certified inspectors who document damage the way adjusters expect it. We handle the entire insurance claim process so you don't have to.

GAF Master Elite Certified

Only 2% of roofing contractors in the country hold GAF Master Elite certification. That gives Alviso homeowners access to the Golden Pledge warranty: 25 years on workmanship, 50 years on materials. It's the strongest warranty in the industry.

Alviso Roofing FAQ

Most residential roofs are completed in a single day. We stage materials the day before and our crew arrives at 7 AM. Larger homes, steep pitches, or multi-layer tear-offs may take two days. We never leave a roof uncovered overnight.

Most inspections are scheduled within 48 hours. For storm damage or active leaks, we prioritize and can usually get a crew out same-day or next-day. Call (877) 586-1316 and we'll give you a specific timeframe.

Often, yes. Not every roof problem requires a full replacement. If the damage is isolated (a few missing shingles, a flashing leak, a small area of hail damage), a repair may be the right call. We'll inspect and give you an honest recommendation.
