Why Hollywood Roofing Co Is San Gabriel’s Preferred Roof Replacement Team
San Gabriel homeowners face a problem most roofing companies never see: century-old homes with original clay tile that cannot simply be torn off and replaced with composition shingle. The city’s strict historic preservation guidelines in the Mission District and surrounding core mean a roofer either knows how to preserve original materials or they do not. We do.
Our team has spent years working on the 1920s through 1950s Spanish Colonial Revival and Craftsman homes that define San Gabriel’s streetscape. We have sourced matching salvaged clay tiles from local architectural salvage yards, navigated the limited attic access common in pre-1940 construction, and worked within the design review process that protects this city’s character. One recent job, a 1925 Spanish Colonial near the San Gabriel Mission, had original clay tiles lifting along the ridges after a Santa Ana wind event. We removed each tile, replaced the failed underlayment with high-temp ice and water shield, reinstalled the tiles with stainless-steel fasteners, and replaced flashing at every penetration. The homeowner kept the historic look and gained a watertight roof that will outlast the next decade of windstorms.
Whether your roof needs a patch or a full replacement, we handle it start to finish. Roland Vega leads our crew with the kind of quiet competence San Gabriel homeowners respect. We do not pressure, we do not upsell, and we do not pretend a 90-year-old roof is the same as a 15-year-old roof.
Styles & brands we work with
Asphalt Shingle Roof Replacement in San Gabriel
Asphalt shingle roof replacement is our most common job in San Gabriel’s eastern tracts, where mid-century homes built in the 1950s and 1960s dominate the 91775 and 91776 zip codes. A typical asphalt shingle roof replacement in San Gabriel runs $8,500 to $14,500 for a standard single-story home, depending on square footage, tear-off requirements, decking condition, and shingle grade.
Architectural Shingles for San Gabriel’s UV Exposure
San Gabriel sits in the San Gabriel Valley with hot, dry summers and intense sun exposure that degrades cheap 3-tab shingles years earlier than in coastal areas. We recommend architectural shingles for most San Gabriel homes because the thicker multi-layer construction stands up to UV granule loss better than entry-level shingles. The price difference, usually $1,500 to $3,500 more per roof, buys you roughly 10 to 15 additional years of service life in this climate.
When Roof Decking Needs Replacement
On homes from the 1950s and earlier, rotted or delaminated roof decking is common, especially where original roofs leaked slowly for years before anyone noticed. When we tear off an old roof in San Gabriel and find decking problems, we replace the damaged sections with new OSB or plywood before laying underlayment. We show you photos of the decking before any work proceeds, so the final invoice is never a surprise.
New Roof Installation in San Gabriel
New roof installation for additions, ADUs, and new construction in San Gabriel runs $11,000 to $22,000 depending on roof size, pitch, and material. Homeowners adding an ADU in the rear yard of a 91776 property, for example, typically need a new roof that meets current Title 24 cool-roof standards, which shapes both product choice and cost.
ADU and Addition Roofs
San Gabriel has seen steady ADU construction since California loosened the rules, and each ADU needs a roof that integrates with the main house. We install new roofs on detached additions and ADUs using materials that complement the existing structure. If your main house has clay tile and your ADU needs a lighter, more affordable option, we can match the color palette with certain architectural shingle lines rather than forcing an expensive tile match.
Flat Roofing for San Gabriel’s Mid-Century Homes
A number of San Gabriel’s 1960s and 1970s ranch homes have low-slope or flat roof sections over carports, patios, and additions. Flat roofing replacement in San Gabriel typically runs $9,000 to $16,000 depending on the roof’s size and whether we use a multi-ply modified bitumen system or a single-ply membrane. Flat roofs here need UV-resistant surfacing because San Gabriel’s summer sun breaks down unprotected asphalt surfaces faster than in coastal climates.
Trusted Brands We Service in San Gabriel
As authorized installers across seven leading roofing brands including GAF, CertainTeed, Tamko, and Boral, we give San Gabriel homeowners genuine material choice rather than a single-brand take-it-or-leave-it offer. Seven leading brands. One honest recommendation. For a Mission District tile restoration, we lean toward Boral for its clay tile lines and color matching. For an eastern San Gabriel tract home, we often recommend GAF or CertainTeed architectural shingles for their heat-reflective granule technology and warranty depth. For a budget-conscious landlord on a mid-century rental, Tamko delivers solid performance without the premium price. We stock common materials locally and can typically begin a San Gabriel roof replacement within two to four weeks of contract signing.

AfterCommon Roof Replacement Problems We See in San Gabriel Homes
- Failed underlayment beneath intact clay tiles. The original 1920s tiles look fine from the street, but the felt paper underneath has disintegrated. Hidden leaks only show up during winter rains, often appearing as interior plaster cracks along ceiling lines. The fix is a full tile-off restoration, not a patch job.
- Santa Ana wind damage to ridge tiles and drip edge. San Gabriel sits close enough to the San Gabriel Mountains that strong offshore winds hit the city’s older roofs hard. Original fasteners corrode over 80 to 100 years, and ridge tiles start lifting. Once a ridge tile goes, water gets into the roof deck within days.
- Accelerated granule loss on asphalt shingles. The eastern ZIP codes of 91775, 91776, and 91778 have large mid-century tracts where original composition roofs are hitting the end of their 25-to-30-year lifespan. San Gabriel’s UV intensity strips granules faster here than in coastal cities, exposing the fiberglass mat and causing curling and cracking within a decade of installation on cheap shingles.
- Limited attic access in pre-1940 construction. Many San Gabriel bungalows and Spanish Colonials have extremely tight attic spaces with no room for modern ventilation baffles or easy decking inspection. We have worked in these attics enough to know where the trouble spots are, and we plan replacement work around the structural constraints rather than treating them as an afterthought.

FAQs About Roof Replacement in San Gabriel
We work with Southern California architectural salvage yards and tile suppliers who stock reclaimed and new-match clay tiles in the specific profiles used on San Gabriel’s 1920s Spanish Colonial homes. We remove intact tiles carefully, catalog them by location and condition, set aside the salvageable ones for reinstallation, and only source replacements for the broken or missing pieces. The goal is a roof that looks original from the street while performing like new underneath. Call (833) 589-7971 to discuss your specific tile profile and color match.
For most San Gabriel homes, we recommend architectural asphalt shingles with high wind ratings and reflective granule technology, or restored clay tile if your home is in the historic district. Santa Ana winds require shingles rated for at least 110 mph uplift and starter strips at every eave and rake edge. We also use stainless-steel fasteners on clay tile restorations to resist the corrosion that causes tile loss after decades of wind exposure.
The coastal spec uses hot-dipped galvanized or stainless fasteners, high-bond self-adhered underlayment at eaves and valleys, and materials rated for salt air and wind-driven rain. San Gabriel’s inland spec focuses on UV resistance, high-temp underlayment that will not melt or degrade at attic temperatures above 140 degrees, and shingles with reflective granules to reduce heat absorption. The fasteners still matter here, not because of salt, but because Santa Ana winds test every staple and nail. The coastal-spec materials cost 10 to 20 percent more, but using the cheaper inland-spec product on the wrong home means early fastener corrosion and underlayment failure within a decade.
San Gabriel’s summer heat pushes attic temperatures well above 140 degrees, which accelerates shingle degradation from the underside and can warp roof decking over time. Proper intake at the eaves and exhaust at the ridge or through roof vents creates airflow that keeps attic temperatures closer to ambient. On older San Gabriel homes with limited attic access, we often add ridge vents and low-profile intake vents during a roof replacement to extend the life of the new roof. Call (833) 589-7971 and we will check your attic ventilation as part of the free estimate.
Yes, and we do it regularly. The key is working with the city’s design review process before and during the project, submitting material samples, color matches, and a removal and reinstallation plan that preserves original tile where possible. We have completed multiple Mission District replacements where the original clay tile was reinstalled over new underlayment, and the city approved the work because the historic appearance remained intact. We can guide you through the permit and review process from start to finish.
