Installing a roof on new construction or an addition is the one time you get to do everything right — no compromises from existing conditions. We start from the roof deck and build up with proper ice and water shield, synthetic underlayment, drip edge, and ventilation before a single shingle goes on.
Complete System Design
Underlayment, flashing, ventilation, and materials selected as an integrated system — not afterthoughts bolted on.
GAF Master Elite Certified
Top 2% of roofers nationally. Unlocks manufacturer warranties up to 50 years with full system coverage.
Ventilation Engineering
Balanced intake and exhaust ventilation sized to your attic volume. Prevents condensation, ice dams, and premature aging.
Permit Management
We pull permits, schedule inspections, and handle every code requirement. You deal with zero paperwork.


How We Build Your Roof
Roof Deck Preparation — Every installation starts with inspecting the decking substrate. We verify structural integrity, replace any damaged sheathing, and ensure proper nailing patterns. The deck is the foundation — skip this step and everything above it fails.
Underlayment System — We install synthetic underlayment across the entire roof deck, with ice and water shield membrane in valleys, at eaves, around penetrations, and along wall junctions. This secondary water barrier is your insurance against wind-driven rain.
Flashing & Drip Edge — Aluminum drip edge at eaves and rakes, step flashing at walls, counter-flashing at chimneys, and custom-fabricated pieces for complex intersections. Flashing is where most roofs fail — we don't cut corners here.
Ventilation — Ridge vents paired with soffit intake vents, sized to provide 1 sq ft of net free area per 150 sq ft of attic space. Proper ventilation extends shingle life by 20-30% and prevents moisture damage to insulation and framing.
Material Installation — Whether architectural shingles, standing seam metal, clay tile, or composite slate, every material has specific manufacturer requirements for fastener type, spacing, and overlap. We follow them exactly — that's what makes the warranty valid.
Materials We Install
Asphalt Shingles — The most popular choice in the East Bay. Architectural (laminate) shingles offer better wind resistance and aesthetics than 3-tab. GAF Timberline HDZ rated for 130 mph winds. 25-50 year warranties available.
Metal Roofing — Standing seam or corrugated panels. Energy-efficient, fire-resistant (Class A), and rated for 40-70 years. Higher upfront cost, lowest lifetime cost. Ideal for the East Bay's fire-prone hillside neighborhoods.
Tile Roofing — Clay and concrete tile is common in older East Bay homes. Heavy — requires engineered trusses. But lasts 50-100 years with proper installation. We verify structural capacity before quoting tile.
Composite & Synthetic — Modern composites mimic slate or wood shake at half the weight and a third of the cost. Impact-resistant, Class A fire rated, and 50-year warranties. Growing fast in the East Bay market.
East Bay Installation Considerations
The East Bay's diverse microclimates affect material selection. Hillside homes in the Oakland and Berkeley hills face higher fire risk and wind exposure — Class A fire-resistant materials with enhanced wind ratings are essential. Homes in Walnut Creek and Concord deal with extreme summer heat — cool roof coatings and reflective materials reduce energy costs. Coastal-adjacent areas like Fremont and Hayward need corrosion-resistant flashing and fasteners.
Our installers are licensed, bonded, and insured in California. We carry $2M general liability and workers' comp on every crew member. Your property is protected from day one.

Frequently Asked Questions
How long does a new roof installation take?
Most residential installations take 2-5 days depending on roof size, pitch, and material. A standard 2,000 sq ft asphalt shingle roof typically takes 2-3 days. Tile and slate installations take longer due to the weight and precision required.
Do I need a permit for a new roof in the East Bay?
Yes. Contra Costa and Alameda counties require building permits for new roof installations. We handle the entire permit process — application, inspections, and final sign-off. The permit cost ($200-$500) is included in our estimates.
What's the difference between installation and replacement?
Installation is for new construction or additions where no roof existed before. Replacement involves tearing off the existing roof first. Installation is typically faster and less expensive since there's no tear-off labor or disposal costs.
Can I install a different material than what my neighbors have?
In most East Bay neighborhoods, yes. Some HOAs have material and color restrictions. We'll check your CC&Rs and local building codes before recommending materials. Fire-resistant Class A materials are required in California WUI zones.

If your new construction has unusual geometry — multiple dormers, steep pitches over 8:12, or limited access — costs go up significantly. We'll quote it honestly. Also, if you're adding a room and trying to tie into an aging existing roof, you may be better off replacing the whole thing rather than dealing with mismatched materials and seams that will fail first.
