Owens Corning Specialty Roofing in Los Angeles: What to Know First
We provide independent Owens Corning specialty roofing service across Los Angeles, with most diagnostic calls completed same-day and repairs typically finished within 48 hours. Our estimates are upfront - the number we quote is the number you pay - and every job carries our written 90-Day Done Right Promise. This page is for homeowners who already have Owens Corning specialty roofing materials in place, whether it’s a TPO membrane on a Mid-City commercial building, a Solar Ready roof in the Valley, or modified bitumen aging on a Hancock Park flat roof. If you’re seeing cracks, pooling, or interior staining, call us at (844) 563-1816. A real person answers, 24 hours a day.
How Owens Corning Products Fail - and How We Fix Them
- Owens Corning TPO on low-slope Valley roofs: The 60-mil and 80-mil TPO membranes we see in North Hollywood and Studio City often develop seam separation where the heat-reflective white surface contracts against Los Angeles’s 100°F summer days and 45°F winter nights. We cut back to sound substrate, weld new membrane with hot-air equipment, and test every seam with a probe - not a visual guess.
- Solar Ready Roofing (SBS-modified base) with premature granular loss: This system was designed to accept panel mounts, but we’ve found the granule-surfaced cap sheet sheds prematurely when installers walk it repeatedly without protection pads. We source matching Owens Corning SBS cap sheets or compatible alternatives, then install walkway pads in high-traffic zones so the repair holds.
- EPDM rubber roofing on Eastside duplexes: The black membrane absorbs heat, accelerating adhesive failure at membrane-to-flashing joints in Eagle Rock and Highland Park. We strip the failed lap, prime with EPDM-specific bonding adhesive, and install reinforced termination bars - never generic caulk that’ll harden and crack by next summer.
- Modified bitumen (torch-applied) with alligatoring: Common on 1990s-era flat roofs in Koreatown and Westlake, the APP-modified cap sheet develops surface cracking when attic ventilation is poor and summer roof temperatures exceed 160°F. We assess whether a full cap-sheet replacement is warranted or if a compatible SBS overlay with proper venting solves it - we don’t sell more than the roof needs.
- Built-up roofing (BUR) with blisters between plies: The multi-ply asphalt-and-felt systems we encounter in older Los Angeles commercial buildings trap moisture from our occasional heavy winter rains. We core-cut to identify the ply depth, dry the cavity with heat, and patch with compatible asphalt and reinforcing fabric - never just surface-sealing, which traps the problem inside.
Our Owens Corning Specialty Roofing Process
- 1
Call and schedule: A live person answers, day or night. We book your inspection, usually within 24 hours in Los Angeles.
- 2
Photo-documented inspection: Our background-checked, uniformed technician walks your roof, shoots every detail, and shows you the actual problem - not a diagram from a sales binder.
- 3
Parts decision: We source OEM Owens Corning materials when available and cost-justified. When lead times stretch or the line is discontinued, we specify quality aftermarket alternatives that won’t void your remaining system warranty.
- 4
Repair execution: We complete most specialty roofing repairs in a single visit. Pete Navarro still reviews every Owens Corning job sheet before the crew heads out - old habit from when we were a three-man operation.
- 5
Testing and documentation: Seams get probed, laps get flood-tested where accessible, and you receive photos of the completed work.
- 6
The Promise: Your 90-Day Done Right Promise is active the moment we finish. If it’s not right, we make it right - no paperwork, no arguing.

FAQs
Proper repairs by a qualified professional typically do not void your warranty, but using non-compatible materials or unapproved installation methods can. We use OEM or warranty-compatible aftermarket parts and document our work so you have a record if a future claim arises. Call (844) 563-1816 if you’d like us to review your warranty documents before we start.
Common TPO, EPDM, and modified bitumen components are usually in stock at Los Angeles-area distributors within 24-48 hours. Discontinued Owens Corning lines may take 3-5 business days or require us to source compatible alternatives. We’ll tell you the real timeline before you commit - not after.
Repair is almost always cheaper short-term, but replacement becomes the better value when repairs exceed 30-40% of replacement cost or when the same area has been fixed more than twice. We’ll show you both numbers honestly and let you decide. Call (844) 563-1816 for a free assessment.
We match granule colors from current Owens Corning stock as closely as possible, but sun fading on Los Angeles roofs means a perfect match is rare on repairs over five years old. We always show you the sample before we install it.
Yes. A live person answers our phones 24 hours a day, seven days a week, including holidays. For active leaks, we dispatch to tarp and stabilize immediately, then schedule permanent repair during daylight. Call (844) 563-1816 - we’ll pick up.
A roof doesn’t lie - it just waits until the rain to tell you the truth.
