AfterCertainTeed Roofing: The Los Angeles Owner’s Guide
If you’ve got a CertainTeed roof that’s starting to show its age in Los Angeles, the repair or replacement usually runs between $470 and $2,125 for a repair, and $9,440 to $23,600 for a full replacement. We stock CertainTeed-compatible shingles, underlayment, and flashing on our trucks, and most repairs get done in one visit. The way most homeowners find us is the same way you probably got here: a leak after a Santa Ana windstorm, granule loss showing up in the gutters, or a shingle that’s cracked and curling at the eaves where the afternoon sun hits hardest.
Barrett & Sons Construction is an independent roofing contractor. We’re not affiliated with CertainTeed, but we install and repair their products every week, and we can match your existing roof without guesswork.
Which CertainTeed Models This Applies To
CertainTeed makes several shingle lines, and the parts are not always interchangeable. The Landmark series is the most common roof we see in Los Angeles, and Landmark shingles have a specific thickness and exposure. A Presidential Shake shingle is a different animal entirely: heavier, laminated in three layers, and it needs a steeper roof pitch to shed water the way it’s designed to. If someone slaps a Landmark shingle onto a Presidential roof to patch a small section, it’ll look wrong from the street and it won’t seal properly. We’ve fixed that mistake more than once.
Your best move is to check the original packaging or the contractor’s paperwork if you still have it. No paperwork? Look at the shingle edge. Landmark shingles have a clean, straight edge with a slight taper, while Presidential Shake has an irregular, rough-hewn edge meant to mimic cedar. We bring samples to every estimate so we can match the line, the color, and the weathering pattern. Aftermarket equivalents exist and can save you money, but on a roof that still has ten good years in it, we usually recommend staying with the CertainTeed OEM part so the warranty math stays simple.
Signs Your CertainTeed Roofing Is Failing
- Granules in the gutters or at the downspout elbows. CertainTeed shingles shed granules as the asphalt binder breaks down under Los Angeles UV. A tablespoon or two after a storm is normal; a steady accumulation means the shingle surface is degrading faster than it should.
- Curling at the shingle corners. The south and west faces of Los Angeles roofs curl first because they take the afternoon heat for hours. Once the corner lifts, wind can get under it, and the next Santa Ana event tears it off.
- Water stains on the ceiling or attic rafters, especially near valleys. CertainTeed’s valley flashing fails when the underlayment beneath it has been exposed to too much heat cycling, and a valley leak can travel several feet before it shows up inside.
- Shingles that feel brittle when inspected. If a shingle cracks when you lift it during a visual check, the asphalt is done. Brittle shingles don’t reseal after wind, and you’ll lose more with every storm season.
- Popped nails or exposed nail heads. This happens when the roof deck expands and contracts with temperature swings, and a popped nail becomes a direct water path into your attic. It’s a small fix if caught early, and a big problem if ignored.
Replacement Cost & What’s Included
For a roof repair in Los Angeles, you’re looking at $470 to $2,125. A full CertainTeed roof replacement lands between $9,440 and $23,600 depending on square footage, pitch, and whether we need to replace the underlayment or any decking. Steep roofs and two-story homes cost more because they take longer and require more safety setup. The price includes the shingles, underlayment, flashing, labor, haul-away of the old material, and every nail. We don’t line-item the parts and then add surprise labor at the end.
Every Barrett & Sons roof job gets a written scope before we start, written change orders if anything changes, and the 90-Day Done Right Promise in writing on the contract. If it’s not right, one call brings Tom back. No fine print, no voicemail roulette.
DIY or Call Us?
You can safely check your own roof from the ground or with a ladder: look for missing granules, curling edges, and visible flashing damage. But walking a Los Angeles roof to repair a CertainTeed shingle is where smart homeowners stop. The shingles get slick in the morning fog, the sun bakes them into a brittle surface by noon, and a fall from a one-story roof is a broken hip or worse. If your repair involves the area around a skylight, chimney, or valley, you’re into flashing work where a small mistake leaks for years before you catch it.
If you want us to come take a look, we answer the phone at (877) 610-1318. A live person picks up. No call center, no third-party answering service.
FAQs
Most CertainTeed asphalt shingles in Los Angeles last 18 to 25 years, depending on the line, the pitch, and how much direct sun the roof takes. The south and west faces degrade faster than the north and east, and a roof with poor attic ventilation can lose five years off its lifespan. Call (877) 610-1318 and we’ll give you an honest read on where your roof stands.
Yes, a single damaged shingle or a small section can usually be repaired without re-roofing, as long as the surrounding shingles are still sealing and the underlayment is intact. Repairs run $470 to $2,125 in Los Angeles. If the granule loss is widespread, patching becomes a temporary fix and you’re better off planning a full replacement.
Most single-shine or small-section repairs are done in one visit, usually two to four hours including setup and cleanup. If we need to remove and replace valley flashing or underlayment, it can run into the next morning. We’ll tell you the timeline before we start, in writing.
We keep common CertainTeed Landmark colors, underlayment, and flashing on hand, and we bring samples to match the exact shingle and weathering. If your roof uses a less common line like Grand Manor or Carriage House, we’ll order the OEM part and schedule the repair as soon as it arrives.
If your CertainTeed roof is showing any of the signs above, or if you just want a straight answer about what you’re looking at, call Tom and the crew at (877) 610-1318. We’ll walk the roof, show you what we see, and hand you a written estimate. And if you’ve got a second opinion from another contractor, bring it to us. We’ll take a look at no charge inside the county. Permits pulled, inspections signed, and every price change on paper before it touches the job.
