How CertainTeed Products Fail - and How We Fix Them

CertainTeed makes a solid product, but every shingle has its weak points. Here’s what we see on Los Angeles roofs, neighborhood by neighborhood, and what we do about it.

• Landmark shingle granule loss after heat cycles. Los Angeles summers bake roofs in ways the Midwest never does. The Landmark line, the most common CertainTeed shingle we see in L.A., holds up well but can shed granules faster when a roof gets direct afternoon sun with no tree cover. We see it constantly in the San Fernando Valley. Losing granules isn’t cosmetic, it exposes the asphalt layer and shortens the roof’s life. The fix is usually sectional replacement with color-matched Landmark shingles before the underlayment takes damage.
• Presidential shake lifting at the butt edge. CertainTeed’s Presidential shake line is heavy and beautiful, but on older Los Angeles homes we sometimes find the butt edges lifting after years of thermal expansion. The original seal strips lose their bond. When that happens, water gets under the shingle and the decking starts to rot. We re-seal with a proper adhesive rated for L.A. temperatures, and if decking is compromised, we replace that section before reinstalling.
• High-wind uplift on certain ridge caps. Santa Ana winds aren’t kind to ridge caps, especially on CertainTeed roofs where the original installer used fewer nails than the high-wind spec calls for. We find this in the foothill areas, Eagle Rock, Mount Washington, places where wind funnels through. The fix is removing the old ridge cap, checking the underlayment underneath, and reinstalling with the correct nail pattern for Los Angeles wind zones.
• Membrane shrinkage on Flintlastic flat sections. A lot of L.A. homes have flat roof portions, and CertainTeed’s Flintlastic rolls are common there. The failure we see is shrinkage at the seams over ten to fifteen years, which opens small gaps. Water intrusion on a flat roof in Los Angeles is slow and sneaky, nobody notices until a ceiling stain appears. We address it by cleaning the seam area, applying a compatible patching system, and checking the drainage to make sure water isn’t pooling.
• Improper underlayment from the original install. This one isn’t CertainTeed’s fault, but it kills their shingles anyway. In older Los Angeles neighborhoods, we tear off shingles and find the original underlayment was either the wrong type or installed with exposed fasteners that rusted through. If the underlayment fails, the shingles above it fail soon after. When we open a roof and find this, we replace the underlayment to current CertainTeed installation standards before putting anything back.

Our CertainTeed Roofing Company Process

Every CertainTeed job we do in Los Angeles follows the same sequence. You’ll know the price before the first tile moves. Here’s how it works:

1. 1
   You call and describe what you’re seeing. A live person answers, asks the right questions, and schedules a visit. No voicemail, no callback queue.
2. 2
   We inspect in the window we gave you. Our tech walks the roof, checks the decking, the flashing, the ridge cap, and the underlayment. We look for the failure pattern specific to your CertainTeed line, whether that’s Landmark, Presidential, or Flintlastic.
3. 3
   You get a written price before anything is touched. The quote is line-item, and it’s the number. No change orders, no “we found more once we opened it up” games.
4. 4
   We decide on parts together. For CertainTeed shingles, we use color-matched CertainTeed product whenever possible because the color codes matter. For underlayment and accessories, we’ll offer options from the seven manufacturers we stock: CertainTeed, GAF, Owens Corning, IKO, Atlas, Tamko, and Boral. You get a real choice, not whatever is in the truck.
5. 5
   The repair or replacement is completed and tested. We run water over the repair before we leave. We don’t trust our work until we’ve watched it perform.
6. 6
   You get a written guarantee in your hand before the crew leaves. Not emailed a week later. Printed, signed, and left on your kitchen counter. If the repair fails inside the guarantee period, we come back free.

What CertainTeed Roofing Company Costs in Los Angeles

Here’s what CertainTeed work costs in Los Angeles right now, in real dollars:

• Shingle repair (a few Landmark or Presidential shingles): $450-$850
• Ridge cap replacement: $600-$1,200 depending on linear feet
• Flashing repair around chimney or skylight: $500-$1,100
• Flat roof seam repair (Flintlastic): $700-$1,800
• Full CertainTeed roof replacement: $11,000-$24,000 depending on square footage, pitch, and tear-off

What moves the price: the pitch of your roof, how many layers need tearing off, whether decking needs replacement, and which CertainTeed line is going back on. Landmark is the most affordable. Presidential costs more because the shingles themselves are heavier and take more labor. You’ll know your exact number before any work starts. Call (945) 303-9821 for a free estimate.

Why Los Angeles Homeowners Call Tilehurst Roofing for CertainTeed Work

Most of our CertainTeed customers in Los Angeles have already been burned once. They hired someone who didn’t show, or quoted one number and invoiced another. That’s why Tilehurst operates the way it does. Every job gets a written price before work starts, every repair comes with a written guarantee delivered before the crew leaves, and if that repair fails inside the guarantee period, we return at no charge under our 365-Day Done Right Promise. That’s a full year of documented accountability.

Our techs know CertainTeed product lines because they work on them every week, not once a season. And if a repair doesn’t make sense, if the roof is too far gone to justify patching, we’ll tell you straight. We won’t sell you a repair that won’t last. We also aren’t locked into one brand. If a GAF or Owens Corning product is the better answer for your home, we’ll say so. The product fits the home, not our inventory.
