Roofing in Berkeley, CA

Serving Berkeley and Surrounding Areas

What Roofing Includes

A roof inspection starts with a full walk of the rooftop — ridge to eave, valley to rake. We check every penetration.

• Deck condition: rotted plywood or osb, soft spots near valleys, sagging between rafters
• Flashing: step flashing at walls, counter-flashing at chimneys, pipe flashing and boot flashing at vents
• Drainage: gutter, downspout, and scupper function; ponding water on flat sections
• Ventilation: ridge vent, soffit vent, attic fan, and intake balance
• Surface: granulated loss, blistering, uv degradation, cracked sealant

Repairs use primer and mastic or roof cement at seams. A torch applies modified bitumen on flat sections. Every fastener — nail, screw, or anchor — gets set to depth with a nail gun.

Cleanup means dumpster placement, magnetic nail sweep, and debris haul-off. Tarp goes up same-day if rain is coming.

Quality & Materials Standards

Material choice follows roof pitch and structure. Steep gable and hip roofs handle asphalt shingle well, from three-tab shingle to heavier architectural shingle. Cedar shake suits Berkeley's Craftsmans but needs annual attention. Concrete tile and clay tile last decades — if the truss and joist system was built for the load.

Flat and low-slope sections call for membrane systems: tpo, epdm, pvc membrane, or a built-up roof over a proper substrate. Standing-seam panel and corrugated panel work on modern additions and canopies. Every assembly needs underlayment — synthetic underlayment or roofing felt — plus ice-and-water shield at eaves and valleys. Ice dam risk is real in the hills.

Building code in Berkeley requires permit for full tear-off and some repairs. We document conditions with photos before work starts, which matters for an insurance claim.

If storm damage is involved, we help with claim documentation for the adjuster. We can't promise a payout — that's between you and policy coverage. We can separate storm damage from wear, price replacement cost versus depreciation, and file a supplement if the scope of work grows. Deductible and proof of loss are yours to handle.

Coatings extend life on flat roofs. Elastomeric coating, acrylic coating, and silicone coating each have a cure time and coverage rate we state upfront. Reflective polyurethane coating cuts heat load. Primer first — always.
