Residential & Commercial Roofing in Castro Valley
Everything we do is roofing. That focus means our Castro Valley crews install more roofs per year than companies that try to do siding, windows, and remodeling on the side.
Roof Replacement
Owens Corning Duration with SureNail technology or CertainTeed Landmark with NailTrak for reliable fastening in high-wind zones. Both meet ASTM D3462 and carry Class A fire ratings per UL 790. In California, we recommend the high-wind versions rated to ASTM D7158 Class H, which is 130 mph wind warranty. Full system install qualifies for Owens Corning Preferred Protection or CertainTeed SureStart Plus warranty.

Our roof repair process: inspect the issue, identify the root cause, quote the fix, do the work, warranty the repair. Simple. If the root cause is widespread (poor ventilation causes ice dams, for example), we'll recommend addressing that too. But the choice is always yours.

Wind speeds above 60 mph cause shingle tab lift and adhesive seal failure per ASTM D7158 testing protocols. Our Castro Valley inspectors check the entire windward exposure. Not just the obvious damage. Poor ventilation causes ice dams which cause water intrusion under the shingle field during freeze-thaw cycles. We document all contributing factors so your insurance claim covers root-cause repairs, not just surface patches.

We install new roofs on new homes, additions, detached garages, carports, and covered patios. Material options include asphalt architectural shingles, metal standing seam, metal corrugated, and flat membrane systems. We help you choose based on your budget, aesthetic preference, and the specific demands of your Castro Valley climate.

Metal roofing works on pitches as low as 3:12 for standing seam and as low as 1:12 with specific underlayment and sealant requirements. Steep pitches look incredible in metal. We help you choose the right panel profile, material, and color for your Castro Valley home.

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 Castro Valley crews have installed thousands of shingle roofs and we know the product better than most roofers in the state.

Clogged gutters cause fascia rot, soffit damage, and foundation erosion from concentrated water runoff. That's not a marketing scare tactic. We see the damage on every other gutter replacement in Castro Valley. Properly sized gutters with adequate downspout capacity move water away from the house. We calculate capacity using rainfall intensity data for Castro Valley: roof area x pitch factor x rainfall rate in inches per hour. Standard 5" K-style handles 5,520 square feet of effective roof area.

After we secure the tarp and stop the leak, we photograph and document everything while the damage is fresh. This documentation is critical for insurance claims. Adjusters want to see the damage before any repairs are made.
