Why Los Angeles Homeowners Choose Owens Corning Construction
We provide independent Owens Corning repair in Los Angeles, specializing in roof replacement, roof repair, and metal roofing installations using Owens Corning shingle systems. Penhallow Remodeling Los Angeles is not an Owens Corning factory store and we are not authorized by Owens Corning. We are a licensed general contractor whose crews work on these roofs and insulation systems every week, from Santa Monica bungalows to Silver Lake hillsides, and that daily exposure gives us a repair-or-replace instinct generic roofing companies do not have. Call (213) 277-6578 for a written estimate.
Why Trust Penhallow Remodeling Los Angeles for Your Owens Corning Construction?
Trevor Nash, Owner at Penhallow Remodeling Los Angeles, spent the better part of two decades working residential and light commercial jobs across the Basin before starting this company. He studied construction technology at Los Angeles Trade-Technical College, and he still lives a few miles from where he grew up in the Crenshaw district. What that means for your Owens Corning roof is simple. We know what these shingles do under Los Angeles sun, what Santa Ana winds do to starter strips, and what compressed EcoTouch batts look like after ten years in a tight attic. When we open a roof, we are not guessing.
Our technicians train on Owens Corning product lines specifically. We know the nailing zones on TruDefinition Duration FLEX. We know how Oakridge shingles from the mid-2010s fail at the eaves. We also know when an aftermarket synthetic underlayment will outperform a discontinued Owens Corning product. Every job follows the Kingswell standard: written price before any work starts, a defined arrival window, a clean job site, and a 365-Day Done Right Promise in writing. If the work fails inside the guarantee period, we come back and fix it at no charge.

Common Owens Corning Construction Problems We Fix in Los Angeles
- Granule loss and blistering on older Oakridge shingles. We see this regularly on homes within five miles of the coast, where salt air and intense UV work together. The asphalt dries out, the granules shed into gutters, and small blisters form on the shingle face. It is rarely a manufacturing defect. It is what a good shingle does after fifteen years in Santa Monica air. We strip and replace the damaged field, match the color, and check the underlayment while we are in there.
- Nail pull-through and wind uplift on Duration FLEX roofs. This one is almost always an installation problem, not a shingle problem. If the original crew missed the reinforced nailing zone or skipped the starter strip, the shingles lift at the eaves during Santa Ana wind events. We re-secure with correct nails in the right placement, replace torn shingles, and if the starter strip is missing or failed, we pull the first course and do it properly.
- Visible ridges under metal standing seam panels. A metal roof is only as flat as the deck beneath it. When the synthetic underlayment or the existing decking has warped from moisture, the panels telegraph those defects as visible ridges. We remove the panels, repair or replace the deck, install a fresh underlayment, and re-lay the panel. It is a longer repair, but anything less just moves the wave around.
- Air leaks and mold around compressed EcoTouch insulation. In Los Angeles attics, space is tight, and well-meaning contractors stuff EcoTouch batting into corners to hit an R-value number. Compressing fiberglass kills its R-value. If moisture has been trapped, you get mold on the backside of the drywall. We pull the compressed batts, air-seal the ceiling plane, and re-install to the manufacturer’s loft specification. Then we test with a thermal camera.
- Warped decking from failed underlayment on older Berkshire roofs. Berkshire is a discontinued Owens Corning line, and many of those roofs in central Los Angeles are now twenty-plus years old. When the underlayment fails, water gets to the plywood, the deck swells, and the shingle surface starts to look uneven. If the deck is sound in most spots, we can do a targeted repair. If it is widespread, an honest repair-vs-replace quote is what we hand you, not a patch job.
Owens Corning Parts & Our Repair-vs-Replace Approach
We use genuine Owens Corning components when we are matching an existing roof. That means real Duration FLEX or Oakridge shingles from the same color lot where possible, Owens Corning ridge caps, and their starter strip. But we will not sell you a discontinued Owens Corning underlayment at a markup when a current aftermarket synthetic equals or exceeds it. On metal roofs, we typically recommend a high-quality aftermarket synthetic underlayment, because Owens Corning’s current underlayment lineup is built for shingle systems, not standing seam applications.
Our repair-vs-replace call always starts with an attic inspection. We do not quote a re-roof from a drone photo. We get into the attic, look at the decking from underneath, check for water stains, and measure ventilation. On a roof with five to seven years of life left and local damage, repair makes sense. On a roof with widespread granule loss, curled shingles, and deck questions, replacement is cheaper over the next decade. Call (213) 277-6578 and we will tell you which one yours is.
Our Owens Corning Service Process – Step by Step
- 1
Attic-first diagnosis. Before we touch a shingle, we go into the attic. We check deck condition, ventilation, and insulation. On an Owens Corning roof, the attic tells us more than the surface does. We photograph everything and show you what we found.
- 2
Written line-item repair or replacement plan. You get a written price before any work starts. Not a range, not a verbal ballpark. The number on day one is the number on the invoice. If we find hidden deck damage after tear-off, we stop, show you photos, and get your sign-off on any change. No surprises at the door.
- 3
Repair or installation with Owens Corning components. We install to Owens Corning fastener patterns and nailing zones. Starter strip, shingle field, ridge cap, and ventilation all go in per manufacturer spec. If we are replacing an old Oakridge or Berkshire roof, we typically recommend Duration FLEX in a current colorway.
- 4
Test and walk-through. After the job, we water-test repaired areas, check fastening, and walk the roof with you if it is safe to do so. We show you what we did and why. Then we clean the site. The Kingswell standard is to leave the place cleaner than we found it.
- 5
Written 365-Day Done Right Promise. Every job gets the guarantee in writing. If the repair fails inside a year, we come back and fix it at no charge. No service call, no re-inspection fee. That is the whole point of putting it on paper.

AfterOwens Corning Products We Service & Install in Los Angeles
We work on the full Owens Corning shingle lineup that Burbank Owens Corning service customers and other Los Angeles homeowners actually have on their roofs. That includes TruDefinition Duration FLEX, the current premium architectural line with the reinforced nailing zone, and older Oakridge and Berkshire shingles that are now discontinued but still on thousands of roofs in the Basin. We also install and service EcoTouch Insulation in attics and walls. On metal roofing projects, we install standing seam systems and pair them with appropriate underlayment. We keep common colorways of Duration FLEX in local stock, so a repair on a recent roof does not wait on a freight order.
We Also Service These Brands
Owens Corning is not the only line we work with. Penhallow Remodeling Los Angeles also installs and services KraftMaid and Wellborn cabinetry, Cambria, Silestone, and Caesarstone countertops, and Kohler and Moen fixtures. If your project touches more than the roof, we can handle the whole scope under one written price and one guarantee.
FAQs – Owens Corning Construction Service in Los Angeles
No. We are an independent Owens Corning service provider. We do not represent the manufacturer, and we do not claim any authorization from them. What we offer is hands-on experience with their product lines across Los Angeles, and a written guarantee on our work that Owens Corning does not write for you.
Yes, when matching an existing roof. We use genuine Owens Corning shingles, ridge caps, and starter strips from the same color lot where available. For underlayments and flashings where the Owens Corning equivalent is discontinued or not the best fit, we install high-quality aftermarket components and tell you exactly why. Call (213) 277-6578 for a written estimate.
Most repairs take a single day. A full roof replacement on a typical Los Angeles home runs three to five working days, depending on deck condition, roof complexity, and whether we are pulling multiple layers. Hillside homes in Silver Lake or Echo Park with complex roof geometry can add a day or two. We give you a written arrival window before work starts and we hold to it.
We service TruDefinition Duration FLEX, Oakridge, and Berkshire shingle lines, plus EcoTouch Insulation. Oakridge and Berkshire are discontinued but still on many Los Angeles roofs. If you have any of those lines, we can repair or replace them. If you are not sure which line is on your roof, we can identify it during the estimate visit.
Owens Corning’s manufacturer warranty covers material defects and is separate from our workmanship guarantee. A repair by an independent contractor does not automatically void the material warranty, but improper installation can. That is why we install to Owens Corning’s published fastener patterns and nailing zones. If a material defect is the issue, we will tell you, and we will document it so you have what you need for a manufacturer claim.
