shingle roofing
INSURED

Shingle Roofing

Asphalt shingle roofing is the most common and cost-effective roofing system in San Quentin. Our crews install 15-20 shingle roofs a month. We know the product inside and out. Nailing patterns, exposure measurements, hip and ridge details.

flat roofing
FREE ESTIMATE

Flat Roofing

Commercial flat roof replacement in San Quentin starts with a core sample to check the existing insulation. If it's waterlogged, everything comes off. If it's dry, we can sometimes overlay. Saves you $2-$4 per square foot.

SAME-DAY

Commercial Roofing

We install Carlisle SynTec TPO and EPDM membrane systems with full Carlisle manufacturer warranties. Our San Quentin commercial roofing crews are factory-trained and authorized. TPO seams are hot-air welded at 900+ degrees. The weld is stronger than the membrane itself. Ponding water? We install tapered ISO insulation to create positive drainage per NRCA guidelines.

gutter installation
LICENSED

Gutter Installation

Half-round copper gutters with round downspouts. That's the premium install. We solder joints on-site using 50/50 tin-lead solder. Copper develops a natural patina in California's climate within 5-7 years. For aluminum, we use Spectra Metals .027 gauge seamless with Raytec hidden hangers rated to hold 25 lbs per linear foot of ice and debris load.

roof inspection
TOP RATED

Roof Inspection

Our 27-point roof inspection covers: shingle condition, granule loss, nail pops, lifting tabs, ridge cap integrity, valley flashing, step flashing at walls, drip edge, pipe boot seals, vent function, soffit ventilation, gutter pitch, downspout capacity, fascia condition, decking (from attic if accessible), and visible signs of moisture in the attic. Written report with photos emailed same day.

emergency roof repair
GUARANTEED

Emergency Roof Repair

Fallen tree limb damage requires structural assessment before repair. We check rafter integrity, decking condition, and whether the ceiling joists below were impacted. If structural members are cracked or displaced, you need a framing carpenter before we re-roof. We coordinate with trusted San Quentin contractors for structural work. Insurance carriers require separate line items for structural vs. roofing repairs. We document both.

skylight installation
INSURED

Skylight Installation

Skylight replacement is often better than repair on units over 15 years old. VELUX FCM curb-mount replacement skylights install on the existing curb frame. No structural modification needed. Low-E laminated glass with argon fill for energy efficiency. Solar-powered blinds available for light control. VELUX No Leak guarantee when installed with the complete flashing system. Your San Quentin home gets more light, better insulation, and a proper warranty.

"Had a huge oak branch go through the roof during a storm. San Quentin Roofing & Maintenance tarped it the same night and had the repair done two days later. Insurance covered everything and they handled the whole claim."

FAQ

Frequently Asked Questions

Common signs: curling or cracking shingles, missing shingles after wind events, granule loss (look in your gutters), daylight visible through the attic, sagging roof deck, and age. Most asphalt roofs last 20-30 years in California. If you see any of these, call (877) 586-1316 for a free inspection. We'll be honest about whether you need a replacement or just a repair.

We install GAF Timberline HDZ, Owens Corning Duration, and CertainTeed Landmark. The three most popular architectural shingles in the country. All three are solid choices. GAF gives us access to the Golden Pledge warranty (25-year workmanship). Owens Corning Duration has SureNail technology for wind resistance. CertainTeed Landmark is a reliable mid-range option. We help you choose based on budget, color preference, and warranty goals.

You get two warranties: one from the manufacturer on the materials and one from us on the workmanship. As a GAF Master Elite contractor, we can offer the Golden Pledge. That's 25 years on workmanship plus 50 years on the shingle. Owens Corning and CertainTeed have similar programs. Our own workmanship warranty is in writing and covers installation defects.

Here's the process: we inspect your roof for free, document any storm damage with photos, and help you file the claim. Your insurance company sends an adjuster. We meet them on-site and walk the roof together. If approved, we do the work at the agreed price. If the estimate seems low, we supplement it with additional documentation.

Most residential roofs in San Quentin are done in one day. We show up at 7 AM, tear off the old roof, install the new system, and clean up by end of day. Two-story homes, steep pitches, or large roofs might take two days. We never leave a house uncovered overnight.
