Why Trust Tilehurst Roofing for Your Owens Corning Roofing?

Owens Corning shingles behave differently in Los Angeles than they do in Seattle or Chicago. The sun here bakes sealant strips until they lose their grip. The Santa Anas test every fastener. And the marine layer near the coast keeps some roofs damp for months while inland valleys cook them dry. Our crews have pulled apart enough failed Owens Corning roofs across this city, from Owens Corning service in Glendale to the coast, to know what holds up and what doesn’t.

Greg Holloway grew up in Eagle Rock, right where the 134 meets the hills, and he still lives ten minutes from where he went to school. His instructors at LATTC were working roofers who treated a sloppy flashing job the way a surgeon treats a bad stitch. That standard carries through every Owens Corning job we run. We show up in the window we gave, put the written price in your hands before any work starts, and leave the property cleaner than we found it. That’s the Kingswell Way, and it’s been the foundation of our company since 2000.

Key takeaways:

• Independent Owens Corning service provider, not factory-authorized
• Written price before any shingle comes off
• Written guarantee on every Owens Corning repair, delivered before the crew leaves
• Free second visit if a repair fails inside the guarantee period

Common Owens Corning Roofing Problems We Fix in Los Angeles

• Blown-off Duration shingles from Santa Ana winds. Duration shingles carry a SureNail strip, and when it fails, you lose the seal. We see this most often on homes in the foothill corridors where 60-to-80 mph gusts hit hardest. The fix is usually straightforward: replace the lifted shingles, re-secure the course, and check the surrounding sealant for dry rot that looks fine from the ground but won’t survive the next wind event.
• Sun-baked Supreme 3-tab roofs in the San Fernando Valley. Owens Corning Supreme is a solid entry-level shingle, but on a low-slope Valley roof with zero shade, two decades of UV breaks the asphalt down. Granules wash off, edges curl, and the shingles split at the nail line. Patch jobs buy a season or two at most. When we pull these roofs, the mat underneath is usually brittle enough to snap by hand.
• Dried-out sealant on Duration and Oakridge architectural shingles. Los Angeles summers push roof surfaces past 150 degrees. The factory sealant on architectural shingles can bake out completely, which lets wind get underneath the tabs. The shingles look fine from the street, but they lift with a finger. This is why we inspect the sealant, not just the shingle surface, when a homeowner says the roof “looks okay” but leaks at the edges.
• Failed WeatherLock or WeatherGuard underlayment at valleys and parapets. On flat and low-slope sections, the underlayment does the real waterproofing, and the shingles are just the top layer. Wind-driven rain pushes water sideways here, and if the underlayment was lapped short or torn at a valley, the leak starts underneath a shingle that looks perfectly fine. We see this constantly on Spanish Colonial homes with parapet walls.
• Wood decking rot hidden under Owens Corning shingles. A roof that looks tired usually has decking problems underneath. On older Los Angeles homes, the original skip-sheathing or plywood has been absorbing moisture through failed underlayment for years. You can’t know the full repair scope until the old shingles come off. That’s exactly why we give a written price, but also explain exactly what we’ll do if the decking underneath is soft when we open it up.

Owens Corning Parts & Our Repair-vs-Replace Approach

We use genuine Owens Corning shingles, underlayments, and accessories whenever they’re the right match for the existing roof. That matters because color lots and granule blends shift between production runs, and a mismatched patch looks bad and ages unevenly. When a roof is near the end of its service life, we’ll tell you honestly that a partial repair is a short-term fix, not a solution. We won’t push a full replacement on a roof with five good years left, and we won’t patch a roof that’s already failing in three places. Call (945) 303-9821 and we’ll give you the straight answer after looking at the roof.

Our Owens Corning Service Process - Step by Step

1. 1
   Diagnosis. We inspect the shingle surface, sealant strips, flashing points, and underlayment condition. On Owens Corning architectural systems, we check the SureNail strip integrity, not just what’s visible from the ground.
2. 2
   Written price. You get the full number in writing before any work begins. If we find hidden decking rot or unexpected substrate problems, we stop and talk to you before spending another dollar.
3. 3
   Repair or install. We match genuine Owens Corning products to the existing roof. Every removed shingle is replaced with correct nailing and sealant, not whatever was in the truck.
4. 4
   Test and document. We run water checks on repaired valleys and flashing points, then walk the roof with you if you want. The written guarantee is in your hands before the crew leaves, not mailed three weeks later.
