We’re an independent Owens Corning service provider, so we’re not tied to a single product line and we don’t have to push one shingle over another. What we do is replace Owens Corning roofs the right way: full teardown, honest decking inspection, and a written price in your hands before the first tile moves.

Call (945) 303-9821

If you own a home with Owens Corning shingles and you’re seeing granule loss, curling, or leaks that keep coming back, this page tells you what’s actually happening up there and what a honest replacement should cost. Call (945) 303-9821 and you’ll get a live person, not a voicemail.

How Owens Corning Products Fail - and How We Fix Them

• Duration Series granule loss and premature balding. We see this most on homes in the San Fernando Valley and the flats, where sun exposure runs 300-plus days a year. Owens Corning Duration shingles have a heavy granule embed, but when installation wasn’t done with the right nail placement or the decking wasn’t prepped, the shingles can shed granules early. Once the asphalt is exposed, the shingle cooks from the inside. The fix is a full replacement, because you can’t re-embed granules once they’re gone.
• Oakridge series cracking at the nail line. This shows up on roofs that got nailed too high on the shingle, a common shortcut we find when we tear off older Owens Corning installs. The crack runs right along the nail line and water follows it into the decking. On a replacement job, we pull the whole roof, replace any soft decking, and install with the nail pattern Owens Corning actually specifies.
• Decking rot under older Owens Corning 3-tab roofs. L.A. doesn’t get rain nine months a year, but when it does, it comes hard. Older 3-tab Owens Corning shingles with worn sealant strips let water sit against the decking, and by the time the homeowner sees a ceiling stain, the plywood underneath is often gone. We don’t patch over rotten decking. We cut it out, replace it, and the price for that is in the estimate before we start.
• Hip and ridge cap failure on Duration installations. The hip and ridge caps take the most wind and sun on any Los Angeles roof, and when they’re installed with standard shingles instead of Owens Corning’s own ridge cap product, they fail years early. We replace hips and ridges with the proper cap shingles, not cut-up field shingles.
• Attic ventilation problems that shorten the life of any Owens Corning roof. This one’s less about the shingle and more about how the roof breathes. L.A. attics get brutally hot, and a roof with poor intake or exhaust ventilation will curl Owens Corning shingles long before their rated life. When we replace a roof, we check and, when needed, correct the ventilation so the new Owens Corning product actually lasts.

Our Owens Corning Roof Replacement Process

1. 1
   Call and talk to a person. You call (945) 303-9821, a live person answers, and we schedule a time that works. We show up in the window we gave you.
2. 2
   Full roof inspection, including the attic. Greg Holloway or one of our senior techs walks the roof and goes into the attic. We’re looking at decking, ventilation, flashing, and how the Owens Corning shingles have been wearing. You get photos and a plain-language explanation of what we found.
3. 3
   Written price before the first nail. We hand you a line-item estimate. It includes tear-off, decking replacement (if needed), underlayment, shingles, flashing, ridge cap, cleanup, and the permit. If the decking is fine, the price doesn’t change when we open the roof. We don’t do change orders on hidden surprises.
4. 4
   Tear-off and decking inspection. The old Owens Corning roof comes off down to the sheathing. If we find rot, we replace it at the per-sheet price already in your estimate. Then we lay new underlayment and install the new Owens Corning system.
5. 5
   Installation with the manufacturer’s nail pattern and our own quality checks. We follow Owens Corning’s installation specs and then add our own checks at the end of each day. Ridge caps, drip edge, valley flashing: every piece gets looked at twice.
6. 6
   Cleanup and the written guarantee. We magnet-sweep the yard for nails, haul everything away, and hand you a written guarantee before the crew leaves. Under the 365-Day Done Right Promise, if it isn’t done right, we make it right for a full year.

What Owens Corning Roof Replacement Costs in Los Angeles

Most Owens Corning roof replacements in Los Angeles land between $11,000 and $22,000, depending on roof size, pitch, decking condition, and which Owens Corning line you choose. Here’s the real breakdown:

• Owens Corning Oakridge architectural shingles: $11,000 to $16,000 for a typical 1,500 to 2,000 sq ft roof, full tear-off included.
• Owens Corning Duration architectural shingles: $13,000 to $18,500. The step up in price gets you a thicker shingle with better wind and impact ratings.
• Owens Corning Duration Designer (like the shake-look lines): $16,000 to $22,000, depending on style and roof complexity.
• Decking replacement: $90 to $120 per sheet when rot is found beneath the old roof.

What moves the price is decking condition, roof pitch (two-story and steep roofs cost more), and whether we need to correct ventilation. What doesn’t move it: our estimate is a fixed number, not a starting point. Call (945) 303-9821 and we’ll give you a written price for your specific roof. The estimate is free.
