GAF Roofing in Santa Monica, CA | Orange County Roofing Co
We provide independent GAF roofing repair and replacement across Santa Monica, from leak diagnostics on Timberline shingle systems to full EverGuard TPO re-covers on flat apartment roofs. The one thing that makes our GAF work different here is simple: we install and service these systems with coastal salt, onshore wind, and Santa Monica’s historic-district constraints in mind from the first inspection. If you’re looking for roofers who understand how GAF materials actually perform three blocks from the Pacific, call us at (866) 942-4187 for a free estimate.
Why Santa Monica Residents Choose Us for GAF Service
Our crews work on GAF systems up and down the coast, from GAF repair in Venice to Santa Monica, so we know how Timberline shingles and EverGuard membrane behave when marine air gets aggressive. That’s the difference between a roofer who installs GAF products and one who knows how they fail in 90402 versus inland. We use genuine GAF components on every repair or replacement: Timberline HDZ and UHDZ shingles, GAF ridge vent, starter strip, and Liberty self-adhering underlayment. No mismatched aftermarket shingles that void the system warranty and leave you holding a cross-manufacturer gap.
Kurt Hensley, our owner, grew up watching crews work tile roofs in the hills and has spent the better part of two decades on California roofs before launching Orange County Roofing Co. He’s built the business on straight answers: we repair when a repair makes sense, and we recommend replacement when the deck or fasteners are compromised. A roof shouldn’t be a mystery, as Kurt puts it, let’s just look at what you’ve got and go from there.
We also carry seven major shingle brands, including GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That means our GAF recommendation comes from matching the right product to your Santa Monica roof, not from a manufacturer’s incentive program.

Common GAF Roofing Problems We Solve in Santa Monica
- Fastener rust-through on beachside GAF shingle systems. Salt-laden marine air chews through standard steel nails and drip edge quickly. On homes in 90402 and Ocean Park, we regularly find fastener heads rusted flush within a decade while the Timberline shingles still look serviceable from the curb. The deck is compromised beneath a roof that looks fine.
- Wind-driven rain wicking under Timberline field shingles. Steady onshore gusts push moisture under shingles at hip and ridge terminations on low-slope transitional roofs. We see this on the post-war stucco tracts and hillside moderns where roof geometry creates wind channels that inland homes never experience.
- Cracked and brittle GAF underlayment beneath intact barrel tile. On 1920s and 1930s Spanish-revival bungalows in 90401 and 90404, fog-driven moisture cycling breaks down the underlayment mat while the tile on top looks untouched. Homeowners see interior ceiling stains and assume the tile failed. Usually it’s the waterproofing layer beneath.
- EverGuard TPO seam failures and ponding at scuppers. Older courtyard apartments and flat-roof buildings along Ocean Park trap fog moisture at TPO seams, leading to recurring leaks that tenants report as shingle problems. The fix is membrane-level, not shingle-level.
- Landmarks Commission hold-ups on visible roof changes. If your Spanish-revival bungalow sits in a designated historic district, Santa Monica’s Landmarks Commission reviews the visible shingle or tile profile before any bundle goes up. We’ve walked homeowners through that approval process more times than we can count.
GAF Service in Santa Monica: What Local Conditions Mean for Your Equipment
Here’s something you won’t read on a generic GAF page: Santa Monica’s Landmarks Commission reviews roof changes on designated historic properties, and a large share of the Spanish-revival bungalows in 90401 and 90404 sit inside those districts. That means a GAF reroof here can require approval of the visible shingle or tile profile before we order the first bundle. On a GAF in Culver City reroof, that step simply doesn’t exist. What it means in practice: we help Santa Monica homeowners identify whether their property is landmarked, prepare the material and color documentation the Commission wants to see, and sequence the work so the review doesn’t stall the job. It’s a permitting and coastal-durability job as much as an installation job. If you’re on a flat roof off Ocean Park, the issue is different: EverGuard TPO seams trap fog moisture and fail at the welds, so we focus on seam integrity and scupper drainage during every inspection.
GAF Models & Products We Service in Santa Monica
We service and install the full GAF residential and commercial roofing range you’d find on Santa Monica homes and apartment buildings. The list includes Timberline HDZ architectural shingles for pitched roofs, Timberline UHDZ for premium architectural profiles, EverGuard TPO for flat and low-slope apartment stock, and Liberty Self-Adhering Underlayment for the coastal moisture and wind conditions that drive so many local failures. We stock genuine GAF ridge vent, starter strip, and Liberty underlayment so typical Santa Monica repairs move fast without waiting on special orders. On the parts side, we use OEM components almost exclusively: a GAF system’s warranty and coastal performance depend on matched materials, and we won’t cut that corner.

GAF repair in Beverly Hills and Santa Monica typically runs $350 to $900 for leaks, flashing, and vent boot work, while a full Timberline replacement on a standard Smith-Corcoran-era pitched roof lands between $12,000 and $25,000 depending on square footage, tear-off requirements, and whether Landmarks review applies. EverGuard TPO re-covers on flat apartment roofs range $9,000 to $18,000. Tile underlayment replacement on a Spanish-revival bungalow, where we pull and reset the original tile, usually costs $18,000 to $32,000. Those are real Santa Monica numbers, not national averages.

FAQs – GAF Roofing in Santa Monica
Yes, if your property sits in a designated historic district or is individually landmarked, Santa Monica’s Landmarks Commission typically reviews the visible roof material and profile before you can proceed with a reroof. We help you determine the property’s status, prepare the required documentation, and choose GAF materials that satisfy the Commission’s compatibility standards. Call (866) 942-4187 if you’re unsure whether your home is affected.
Salt-laden marine air from the Pacific accelerates corrosion of standard steel fasteners and flashing on beachside homes. Within a decade, fastener heads can rust through while the Timberline shingles still look presentable, leaving your deck compromised under a roof that appears sound. We identify these failures during inspection and replace with corrosion-resistant fasteners and flashing on coastal jobs.
On flat and low-slope roofs along Ocean Park, recurring seam leaks are almost always the EverGuard TPO membrane, not shingles. Weld failures at the TPO seams trap fog moisture and let water through, and ponding at scuppers makes it worse. Our repair focuses on re-welding seams, correcting scupper drainage, and inspecting the membrane field for hidden punctures. Call (866) 942-4187 for an inspection and exact repair quote.
We repair when the shingle field is sound and the failure is localized to flashing, vent boots, or a small section of shingles. We recommend full replacement when the fasteners or underlayment are corroded through, especially on beachside homes where patching a compromised GAF system just moves the leak to the next weak spot. Our inspection tells you which situation you’re in.
Yes. Coastal fog drives moisture cycling that breaks down the underlayment mat beneath intact barrel tile. On 1920s Spanish-revival homes, the tile stays put while the GAF underlayment beneath becomes brittle and cracked, letting water through to the decking. We replace the underlayment, re-flash the valleys, and reset the original tile. Call (866) 942-4187 for a free inspection and line-item quote.
