Why San Francisco Residents Choose Us for CertainTeed Service

We’ve been working with CertainTeed products in San Francisco since 2010 - over 500 installations spanning Landmark shingles, Presidential Tile, and Flintlastic SA membranes on the flat decks tucked behind so many Victorian facades. Pete Navarro, our owner, started this company in 1984 after coming up through Los Angeles Trade-Technical College and spending twenty years on roofs across the San Fernando Valley and Eastside. He talks about underlayment too much at dinner, his daughter says. That same obsession is what keeps water out of your attic.

We’re not an authorized CertainTeed contractor. We’re independent. That means we specify what your roof actually needs, not what a manufacturer program pushes this quarter. We stock Flintlastic SA cap sheet, Landmark Solaris in popular color blends, and the specialized copper and stainless flashings that San Francisco’s parapet walls eat alive. Our technicians are background-checked, uniformed, and they photograph every inspection from your actual roof - not the driveway. Phones are answered by a live person 24 hours a day, including the middle of a January storm when your scupper backs up.

Our CertainTeed sales & service philosophy is straightforward: genuine CertainTeed materials where they protect your warranty pass-through, commercial-grade aftermarket where CertainTeed doesn’t supply the component, and an honest repair-vs-replace recommendation based on how many years of service life remain. The 90-Day Done Right Promise covers every job - if it’s not right, we come back and make it right, no paperwork, no arguing.

Common CertainTeed Roofing Problems We Solve in San Francisco

• Algae discoloration on Landmark shingles in marine fog zones. The Sunset District gets hit hardest. CertainTeed’s algae-resistant granules work, but the persistent summer fog in San Francisco keeps shingles damp for weeks straight, giving algae a foothold that inland Bay Area roofs never see. We clean with manufacturer-approved methods and assess whether granule loss has progressed past cosmetic.
• Flintlastic SA membrane edge lifting from westerly wind under-pull. Self-adhered cap sheets depend on proper roll pressure and clean substrate. San Francisco’s prevailing westerlies off the Pacific find any gap at the edge, working moisture underneath and delaminating the seam. We seal edges with compatible mastic and mechanical fastening where wind exposure is severe.
• Parapet flashing corrosion on Presidential Tile where fog moisture lingers. Copper step flashings look good on paper, but San Francisco’s fog carries enough salt to pit them over time, especially on Nob Hill and Pacific Heights homes where the marine layer sits longest. We inspect for green-tinged weep holes and degraded solder joints.
• Landmark Solaris granule loss from surfaces that never fully dry. Reflective shingles need dry surfaces to shed UV. In San Francisco, fog-dampened Solaris shingles in shaded courtyards or north-facing slopes stay wet for days, accelerating granule shedding and UV degradation of the asphalt core. We evaluate whether full replacement or targeted patching makes sense.
• Multi-layer BUR soft spots trapping moisture under newer CertainTeed membranes. Many Mission and SoMa buildings carry four or five re-coat layers because attached configurations made tear-offs impractical for prior contractors. We probe for delamination, remove saturated material, and reinstall with proper slope to scuppers.

CertainTeed Service in San Francisco: What Local Conditions Mean for Your Roof

San Francisco’s 1906 earthquake and fire destroyed over 28,000 buildings, but the surviving Victorian row houses - many in Pacific Heights and Alamo Square - often have original brick party walls that require specialized CertainTeed flashing details to bridge the thermal and moisture movement between old masonry and modern roofing membranes. These walls expand and contract on a different cycle than wood framing, and the lime mortar in pre-1906 brick is more permeable than modern Portland cement, meaning moisture wicks through differently. When we install CertainTeed Flintlastic SA on a flat deck against a century-old party wall, we don’t just terminate the membrane. We specify a reglet detail or expansion-joint counterflashing that accommodates differential movement without tearing the cap sheet. Miss this, and you’ll be patching the same corner every three years. We’ve learned that the hard way, and now we build it in from the start.

This same seismic history shapes what we can put on your roof. San Francisco’s high Seismic Design Category restricts added dead load. A heavy Presidential Tile system or another gravel BUR layer on an already burdened Victorian structure may look fine in the estimate, but it won’t pass structural review. We calculate total load against lateral capacity, and we’ll tell you straight when a lighter CertainTeed system is the only code-compliant path.

Our San Francisco service area covers the dense core ZIPs - 94105, 94107, 94108, 94109 - where ladder access is tight, rear yards are narrow, and every job requires coordination with neighbors who share your walls. We’ve worked in these conditions long enough to know which buildings need scaffolding permits, which alleyways accommodate a material hoist, and where the city’s street-sweeping schedule will complicate dumpster placement.

CertainTeed Models & Products We Service in San Francisco

We carry and install genuine CertainTeed materials for warranty compatibility: Landmark and Landmark Solaris for visible pitched surfaces, Presidential Series where weight allowances permit, and Flintlastic SA self-adhering modified bitumen for the flat decks hidden behind so many San Francisco parapets. For underlayments and ice-and-water shield where CertainTeed doesn’t offer a direct equivalent, we source Grace or comparable commercial-grade aftermarket - never builder-grade substitutions.

Local stock matters in San Francisco. We keep Flintlastic SA in granulated and smooth cap, plus the color-matched sealants and primers that fog-zone repairs demand. Most flat roof patches and flashing repairs complete in a single visit. Roof Replacement & Installation in San Francisco on attached row houses typically runs 2-4 days depending on tear-off depth and access constraints.

FAQs - CertainTeed Roofing in San Francisco

Does CertainTeed’s 50-year warranty cover fog damage on my Mission flat roof?

No. CertainTeed’s material warranty covers manufacturing defects, not environmental exposure to San Francisco’s marine fog. Fog-driven moisture infiltration is an installation and maintenance issue, which is why our 90-Day Done Right Promise on workmanship matters more here than the manufacturer’s paper. Call (844) 563-1816 for a free inspection - we’ll document what’s fog damage versus what’s a material defect.

Can you install CertainTeed Landmark shingles on a Victorian with a visible pitch?

Yes, where the structure shows a true pitched roof. Many San Francisco Victorians present ornate gables to the street but conceal flat decks behind parapets - Landmark goes on the visible pitch, Flintlastic SA on the hidden flat. We assess each building individually; some Pacific Heights homes have more pitch than they appear from the sidewalk.

How do you handle CertainTeed flashing at shared party walls on zero-lot-line homes?

We use expansion-joint counterflashings or reglet details that accommodate thermal movement between old brick and modern membrane. Standard termination bars crack under differential expansion. We’ve refined our detail through years of callbacks on 1906-survivor buildings - the kind of field knowledge no manual teaches.

Is the CertainTeed Landmark Solaris rated for seismic zones like San Francisco?

The shingle itself meets California building code for fire and wind, but seismic compliance depends on total roof dead load, not the shingle alone. We evaluate whether your structure can handle Solaris’s weight plus underlayment, especially on older Victorians with modified framing. Sometimes a lighter system is the code-compliant choice, and we’ll tell you straight.

Will CertainTeed Flintlastic SA perform well on a Nob Hill roof that gets full sun?

Flintlastic SA is rated for UV exposure, but San Francisco’s combination of intense intermittent sun and prolonged fog dampness creates thermal cycling stress. We specify white reflective cap where sun exposure is concentrated, and we pay special attention to edge fastening where Nob Hill’s wind exposure meets afternoon sun expansion. Call (844) 563-1816 for a site-specific recommendation.
