Why Los Angeles Residents Choose Us for CertainTeed Service
We’ve been on Los Angeles roofs since 1984. Cole Drummond, our owner, grew up in the Crenshaw district and spent summers on flat-tar rooftops before picking up the trade at Los Angeles Trade-Technical College. That background matters when we’re looking at a 1930s Spanish Colonial Revival in Highland Park or a post-war stucco flat-roof in Van Nuys - we understand the framing, the load paths, and the ways this city’s particular combination of heat, UV, and Santa Ana winds punish roofing materials.
Our crew averages 18+ years working CertainTeed systems across Los Angeles County. We stay current on specification details for every product line, from Landmark shingles to Monogram tile, but we’re clear about our position: CertainTeed sales & service from Ridgeline means independent expertise, not a manufacturer-authorized shop. We use OEM CertainTeed shingles and tiles for color match and warranty consistency. For underlayment and flat-roof membranes, we evaluate job-by-job - CertainTeed’s Flintlastic or Base Gard, or a premium aftermarket equivalent, whichever handles Los Angeles heat and wind best.
Every inspection gets photo-documented from your actual roof. Our technicians are background-checked, uniformed, and trained to explain what they found without a sales pitch. The 90-Day Done Right Promise applies to every job: if it’s not right, we come back and make it right. No paperwork battle. No runaround.
A roof doesn’t lie. Sooner or later it tells you exactly what it’s made of.
Common CertainTeed Roofing Problems We Solve in Los Angeles
- Landmark granule loss and tab curling in San Fernando Valley UV zones. Year-round sun and Valley heat exceeding 100°F strip granules and embrittle asphalt. We see Landmark shingles curl at the tabs after 10-12 years here, well short of the 25-year warranty timeline. The fix depends on extent: spot repair with matching OEM shingles, or full replacement if the field is compromised.
- Hidden underlayment failure beneath Monogram tile. On Los Angeles’s enormous inventory of Spanish-style homes, clay or concrete tiles routinely outlast the felt beneath them by 10-15 years. A 20-year-old tile roof often looks intact from the street while #30 felt has cracked from UV and heat cycling. We lead with underlayment inspection, not tile replacement - the real failure is invisible from the curb.
- Flintlastic alligatoring on exposed flat roofs. CertainTeed’s modified-bitumen membranes installed without reflective coating show accelerated surface cracking in Los Angeles’s intense sun. Life drops to 8-10 years on unprotected flat roofs. We evaluate whether a coating restoration buys time or if membrane replacement with proper surfacing is the honest call.
- Carriage House wind damage on steep Hollywood Hills pitches. Santa Ana gusts exceeding 60 mph tear starter strips and hip/ridge pieces when installers used standard four-nail patterns instead of the six-nail reinforced fastening wind maps require. We see this every October through January in hillside neighborhoods.
- Fire-code assembly failures in Very High Fire Hazard Severity Zones. A third of Los Angeles sits in these state-designated zones. Landmark shingles carry Class A rating only with specific substrate assemblies, and LA building inspectors routinely flag permits where the rated assembly isn’t explicitly noted. We handle the compliance documentation so your job doesn’t stall at inspection.
CertainTeed Service in Los Angeles: What Local Conditions Mean for Your Roof
Los Angeles Municipal Code requires Class A fire-rated roofing assemblies across all Very High Fire Hazard Severity Zones - roughly a third of the city’s land area, including Hollywood Hills, Bel Air, Topanga, and Sunland-Tujunga. CertainTeed Landmark shingles meet that rating, but only when installed over the correct substrate: typically #30 felt plus a cap sheet or other approved underlayment combination, fastened per the assembly tested for that rating. LA’s building department inspectors check the permit application against the assembly listed on the manufacturer’s classification report. We’ve seen jobs delayed two weeks because the prior contractor wrote “Landmark shingles” on the permit without specifying the substrate assembly that earns the Class A label.
This matters for CertainTeed owners specifically because the national product literature lists multiple installation options, but only certain combinations satisfy Los Angeles’s dual compliance burden of fire code plus municipal inspection. We handle that specificity on every hillside job. Los Angeles service area coverage means we know which inspector desks ask more questions and which permit applications move fastest.

Full replacements range from $8,500 for a straightforward single-story asphalt shingle job to $22,000 for larger homes with tile or complex flat-roof sections.

FAQs - CertainTeed Roofing in Los Angeles
Not necessarily. In Los Angeles, eight months of dry weather lets small failures hide until December storms hit. We start with a photo-documented inspection of valleys, penetrations, and the shingle field. Often we find isolated wind-lifted tabs or cracked flashing that repairs for $300-$600. If the shingles are brittle throughout and granule loss is severe, we’ll say so and price replacement. Call (877) 367-1429 - we’ll look before we quote.
Heavy clay tile on original 1920s-1940s framing does raise seismic load concerns under current California Building Code requirements. We evaluate the roof structure before recommending tile replacement or overlay. Sometimes a lighter concrete Monogram tile or switching to a composite alternative is the honest recommendation for an older Los Angeles home. We don’t sell you a roof your walls can’t hold.
Mastic over a leaking valley is a temporary bandage that cracks in Los Angeles heat within two seasons. A proper valley repair removes the damaged shingles, installs new ice-and-water shield (or upgraded underlayment in fire zones), and replaces the shingles with correct overlap and fastening. Done right, it lasts the remaining life of the roof. We warranty our valley repairs under the 90-Day Done Right Promise.
Landmark shingles require minimum slope per manufacturer specification - typically 2:12 or steeper with proper underlayment. True flat or low-slope sections need modified-bitumen membrane like Flintlastic, not shingles. We’ve handled many Silver Lake duplexes and courtyard buildings where the main roof is pitched shingle but attached decks or additions are flat. We match the right CertainTeed system to each surface. Call (877) 367-1429 and we’ll assess the slope and recommend accordingly.
We source OEM CertainTeed Carriage House shingles through authorized distribution for exact color match. For discontinued colors, we check manufacturer overstock and regional warehouse transfers before recommending a full-slope replacement. We document the HOA requirement and the color match on every estimate. If your HOA has a specific installation spec (nailing pattern, exposure, etc.), we follow it to avoid rejection.
