Herlong Roofing Experts. Licensed & Insured

Owens Corning Duration shingles with SureNail technology rated to ASTM D3462 and D7158 Class H wind resistance. Our Herlong crews install TruDefinition Duration in a full Owens Corning system. ProArmor synthetic underlayment, VentSure ridge vent, and Starter+ starter strip. Preferred Protection warranty included.

Not every problem needs a full replacement. Sometimes it's a blown-off shingle, a cracked pipe boot, or deteriorated valley flashing. We diagnose the actual issue and fix that. We don't upsell you into a new roof you don't need.

Hail, wind, fallen branches. California storms do real damage to roofs. We respond within 24 hours, tarp exposed areas to prevent further damage, and start your insurance claim with a detailed inspection report.

New construction or an addition? We install new roofing systems from scratch. Decking inspection, ice and water shield, synthetic underlayment, ventilation calculations, and whatever material you want on top. Shingles, metal, or flat.

Corrugated metal and R-panel are cost-effective options for barns, detached shops, and covered patios in Herlong. We install 29-gauge and 26-gauge corrugated with exposed fasteners using neoprene washer screws. For homes, we recommend 24-gauge standing seam with concealed fasteners. Cleaner look, no exposed fastener maintenance. DaVinci composite shake and slate profiles give you the metal longevity with a traditional California aesthetic.

We install asphalt shingles from every major manufacturer. GAF, Owens Corning, CertainTeed, Atlas, Tamko, Malarkey, IKO. Each has different warranty tiers and price points. We walk you through the comparison without pushing one brand.

Flat roofs need special attention. Water doesn't run off, it sits. We install TPO, PVC, EPDM, and modified bitumen systems designed to handle ponding water in California's climate.

Modified bitumen (mod-bit) is still the best choice for high-traffic commercial roofs in Herlong. We torch-apply SBS-modified base and cap sheets over properly primed concrete or approved decking. Two-ply mod-bit systems carry 20-year NDL (No Dollar Limit) warranties through GAF, Firestone, or Johns Manville. NRCA member. We follow the manual.

We install 5" and 6" seamless aluminum gutters in Herlong. Standard homes get 5", high-volume areas and steeper pitches get 6". Downspouts every 30-40 ft of gutter run with splash blocks or underground drains.

Roof inspections after a storm are free. Always. We document hail hits, wind damage, and any pre-existing issues so your insurance claim is accurate and complete.

Emergency roof repairs for active water intrusion follow a strict protocol: tarping with reinforced polyethylene sheeting secured to the roof deck, interior water extraction guidance, and temporary flashing at penetrations. Our Herlong emergency crews carry 20x30 tarps, 2x4 nailer boards, and masonry anchors for various deck types. Permanent repairs are scheduled within 48-72 hours once materials are sourced.

A skylight installed wrong will leak. The flashing has to integrate with the shingle courses. Step flashing on the sides, headwall flashing on top, and a sill pan underneath. We use manufacturer flashing kits because they're engineered to work with the skylight frame.
