CertainTeed Roof Replacement Nationwide

CertainTeed Roof Replacement in Los Angeles: What to Know First

Full CertainTeed roof replacement in Los Angeles typically runs between $11,000 and $28,000 for an average single-family home, depending on the shingle line, the roof’s pitch, and what the decking looks like once we open it up. We are an independent CertainTeed service provider, not a manufacturer-authorized dealer, and we typically complete a full tear-off and replacement in five to eight working days, weather permitting. This page is for homeowners who already have CertainTeed on the roof and want to know whether the replacement should be model-for-model, an upgrade, or something else entirely. Call (945) 303-9821 and we’ll talk you through what makes sense for your house, no charge for the conversation.

If your CertainTeed roof is at the end of its service life, this is the resource for you. Not a brand brochure. Not a generic roofing pitch. The real details, from someone who has torn off more CertainTeed shingles in Los Angeles than we can count.

How CertainTeed Products Fail - and How We Fix Them

CertainTeed makes solid roofing products across the board, but every manufacturer has patterns. Here’s what we see on Los Angeles roofs, by line where it matters, and what we do about it.

• Landmark and Landmark Pro granule loss on south-facing slopes. Los Angeles sun is brutal on the side of the roof that faces Exposition Park or Inglewood. The granules that protect the asphalt from UV radiation start sloughing off after year twelve or thirteen on Landmark shingles faster than on some competitors. Once the granule layer thins, the mat underneath bakes and the shingles crack. We replace with a product matched to the slope’s exposure, sometimes moving a homeowner from standard Landmark to Landmark Pro for its heavier mat, which handles prolonged sun better on the most exposed pitches.
• Presidential Shake TL curling at the butt edge. The luxury shaker look is gorgeous, but in the dry heat around the San Fernando Valley, we see the lower edge of Presidential Shakes begin to cup and lift, especially where attic ventilation is weak. Once the butt edge curls, wind gets underneath and the tear-off risk rises. That’s not a patch job. We pull the affected slopes and re-lay with proper ridge and soffit venting so the replacement doesn’t repeat the same failure in six years.
• XT 30 and CT 20 (discontinued lines) reaching end of life. Both are still on hundreds of Los Angeles roofs built in the 1990s and early 2000s. CertainTeed stopped making them years ago, and any repair now means color-matching to whatever a supply house has in a dusty corner. When these start failing, replacement is almost always the right call, because patching a discontinued shingle is throwing money at a problem that’s already decided.
• Flashing failures at transitions, regardless of shingle line. This one is on the original installer more than CertainTeed, but we see it constantly in older Los Angeles homes: step flashing at the chimney and sidewalls was never replaced when the roof was re-done, so the new shingles get blamed for a leak that’s actually coming from the metal. On every certainteed replacement we inspect and replace all flashing as a matter of course, never as an optional add-on. A roof is a system, and the manufacturer’s shingle warranty doesn’t cover seams that weren’t properly lapped.
• Dry rot in the decking uncovered only after tear-off. We can’t see the plywood or OSB sheet underneath until the old shingles come off. On CertainTeed roofs in older Los Angeles neighborhoods like Eagle Rock or Highland Park, the decking has often absorbed decades of small, slow leaks that never showed on the ceiling. We quote the decking repair cost in writing up front, before we start, so the price doesn’t change when we find rot. That’s how Greg Holloway works: know the price before the first tile moves.

Our CertainTeed Roof Replacement Process

Here’s how a full replacement works with our crew, step by step.

1. 1
   Assessment and written price. We inspect the existing roof, the attic ventilation, and the decking condition where accessible. Then we put a line-item price in your hands before any work starts. No bait number. No revised number at the door.
2. 2
   Product selection. We show you CertainTeed options that match your home’s pitch, exposure, and architectural style, and we also show you comparable lines from GAF and Owens Corning if you want a real comparison. Seven manufacturers available, not just one.
3. 3
   Tear-off and decking inspection. The old roof comes off down to the decking. Any rot or soft sheathing gets replaced, priced as quoted. We don’t bury bad wood under new shingles.
4. 4
   Underlayment and flashing. We lay synthetic underlayment, then install new drip edge at the eaves, new step flashing at sidewalls, new pipe boots, and new valley metal. All of that is part of the job, not a surprise upcharge.
5. 5
   Shingle installation. The CertainTeed line you selected goes down according to the manufacturer’s published installation specs, which keeps the warranty intact. Ridge cap shingles finish the hips and ridges.
6. 6
   Cleanup and written guarantee. We magnet-sweep for nails and haul all debris. Then we hand you the written guarantee before the crew leaves, not mailed weeks later. The 365-Day Done Right Promise covers the work for a full year.
