CertainTeed Roofing in Los Angeles, CA | Mercer Roofing Co Los Angeles
We provide independent CertainTeed roofing service across Los Angeles, from shingle replacement in the Valley to clay tile repair in the Hollywood Hills. What makes our work different here is that we know exactly how CertainTeed products age under LA’s specific conditions: salt air near the coast, brutal UV inland, and Santa Ana winds that find every weak nail line. Call (213) 521-8272 for a written estimate before any work starts. We’re not a CertainTeed affiliate or authorized dealer. We’re an independent Los Angeles Roofing Company that works on CertainTeed systems daily and sources OEM parts whenever repairs are the right call.
Why Los Angeles Residents Choose Us for CertainTeed Service
CertainTeed makes a lot of different roofing products, and they behave differently depending on where in Los Angeles your house sits. A Landmark shingle in Reseda is fighting a different battle than a Landmark shingle in Venice. We’ve spent enough years on roofs across this city to know the difference, and we stock the replacement parts that make sense for each area. We always use CertainTeed-manufactured replacement shingles and flashing components when they’re available, because color-match and wind-rating integrity actually matter. For discontinued lines, we’ll tell you straight: patching with mismatched aftermarket shingles usually costs more in the long run than a ridge-to-eave replacement with a current CertainTeed system. Grant Whitlock, our owner, grew up in Eagle Rock and trained at Los Angeles Trade-Technical College before spending nearly two decades roofing across the LA basin. He’d rather talk you out of a repair that won’t hold than sell you one. For broader CertainTeed sales & service, we cover the full product line.

Common CertainTeed Roofing Problems We Solve in Los Angeles
- Landmark shingles losing granule adhesion and curling after prolonged UV exposure. The San Fernando Valley sees more than its share of 90-degree days, and CertainTeed Landmark shingles in Rancho Cucamonga heat can start shedding granules years before their rated life. We inspect for bare spots and replace individual shingles when the decking underneath is still sound.
- Presidential Shake tabs snapping at nail lines during high-wind Santa Ana events. Ridge-exposed homes get hammered when the winds come through the passes in October and November. CertainTeed Presidential Shake is a heavy shingle, but wind-driven uplift can still snap tabs if the original install over-drove nails or missed the nailing strip.
- CertainTeed membrane seams delaminating on flat roofs where standing water sits. Marine-layer drizzle in West Hollywood and the beach cities leaves water ponding on flat built-up roofs for days at a time. Seam delamination is the classic failure, and we see it most on older CertainTeed membrane systems that were installed before LA’s cool roof codes pushed better reflective surfaces.
- Chimney flashing separation on older clay-tile Spanish-style homes. Earthquake movement shifts chimney stacks, and the flashing that once sealed against the tile pulls away. We replace the flashing and reset the surrounding tiles rather than tarring over the gap, which never holds.
- Cracked original clay tiles on 1920s Spanish Colonial homes. In neighborhoods like Hollywood Hills, Hancock Park, and West Adams, those original kiln-batch tiles are irreplaceable. When one cracks from earthquake settlement or a falling branch, a modern color-matched replacement from CertainTeed’s current clay tile line is the closest you’ll get to seamless.
CertainTeed Service in Los Angeles: What Local Conditions Mean for Your Equipment
In the Hollywood Hills, many 1920s Spanish-style homes still carry their original 2-piece clay tile roofs, and those tiles are not coming back into production. When an earthquake shifts a stack or a eucalyptus branch drops onto the roof and cracks a barrel tile, we have to color-match a modern replacement because the original kiln-batch is gone. CertainTeed’s current clay tile line gives us the closest match for those older glazes and profiles. A quick story: our tech was up on a 1926 Spanish Revival on Outpost Drive after a Santa Ana snapped a clay tile and exposed the underlayment. The original 1920s tile was beyond salvage, so we sourced a close match from CertainTeed’s current line, pulled the broken piece, and reset the surrounding tiles with fresh underlayment beneath. The roof looked seamless, and the owner avoided a full replacement. That’s the kind of situation where you want someone who’s worked on hundred-year-old tile before, not someone seeing it for the first time.
CertainTeed Models & Products We Service in Los Angeles
We work on every major CertainTeed line installed in Los Angeles. That includes Presidential Shake, Grand Manor, Landmark, and Carriage House shingles, plus CertainTeed flat-roof membranes and clay tile systems. When a repair calls for replacement parts, we use CertainTeed-manufactured shingles and flashing components wherever they’re available. We keep common Landmark colors and flashing stock on hand for fast turnaround across the city, and we can order Grand Manor or Presidential Shake without delaying the job more than a day or two. For older discontinued CertainTeed lines, we’ll show you what a patch would look like next to the existing roof and give you an honest recommendation, which is often a full replacement with a current CertainTeed system rather than a mismatched repair.

AfterCertainTeed Service Pricing in Los Angeles

Flashing repair around a chimney is usually $700 to $1,800 depending on how much lead and counterflashing needs replacing.

FAQs – CertainTeed Roofing in Los Angeles
Landmark shingles hold up well in most of Los Angeles, but prolonged UV exposure in the Valley can cause granule adhesion to fail years before the shingle core breaks down. The granule loss shows up as bare spots or excessive granules in your gutters. If you’re seeing that, repair now before the fiberglass mat starts degrading. Call (213) 521-8272 for a free inspection and written estimate.
Yes, if the damage is limited to a few tabs and the rest of the roof is still sound. We replace snapped Presidential Shake shingles individually using CertainTeed-manufactured replacements so the color and wind rating match. If you’ve lost tabs across multiple sections of the roof, that signals a systemic install or uplift problem, and we’ll tell you straight rather than nickel-and-diming you. Call (213) 521-8272 and we’ll assess it honestly.
We repair individual cracked tiles whenever possible. The original kiln-batch tiles from the 1920s are gone, so we color-match a modern replacement from CertainTeed’s current clay tile line, pull the broken piece, and reset the surrounding tiles with new underlayment beneath. A full replacement is only the right call if the underlayment has failed across the whole roof or the tile count is so high that repair costs approach replacement. Call (213) 521-8272 for an exact quote on your specific roof.
Yes, standing water is the number one enemy of flat roof membranes, and marine-layer drizzle in West Hollywood and the beach cities can leave water sitting for days. The failure begins at the seams, where constant moisture weakens the adhesive bond and causes delamination. If you see ponding that doesn’t drain within 48 hours, get the seams inspected now. Call (213) 521-8272 for a free seam inspection and written estimate.
Yes, CertainTeed’s Landmark Solaris line and several lighter Landmark colors meet Los Angeles cool roof reflectivity standards. LA’s cool roof code applies to new construction and re-roofs of certain building types, and your contractor should confirm compliance before the job starts. We can walk you through which CertainTeed colors qualify. Call (213) 521-8272 for guidance specific to your roof.
