Owens Corning Construction in Van Nuys, CA | Mason Remodeling Co Los Angeles
We provide independent Owens Corning roofing and construction service throughout Van Nuys. We’re not a factory branch or an authorized dealer, and we don’t pretend to be. What we are is a local crew that tears off and re-roofs 1940s and 1950s ranchers every week, so we know exactly how Owens Corning shingles, underlayment, and ridge accessories behave on the specific houses that fill this valley. If you’re wondering whether your Owens Corning roof can be repaired or needs replacement, call (213) 632-5711 for a straight answer and a free estimate.
Why Van Nuys Residents Choose Us for Owens Corning Service
Most roofing companies in Van Nuys can nail down a shingle. Few can tell you why your Owens Corning Supreme shingles are losing granules faster on the south slope than the north, or whether that wrinkle near the ridge is a seal-strip failure or a decking problem underneath. That depth comes from repetition. We’ve worked on hundreds of Van Nuys homes built between 1945 and 1965, which means we’ve seen every failure mode Owens Corning products can produce in this climate. Isaac Pruett grew up in the San Fernando Valley and spent his weekends as a kid watching his uncle tear out and rebuild houses on Roscoe Boulevard. That practical education, plus training in construction technology at Los Angeles Trade-Technical College and nearly twenty years of residential work across Los Angeles County, is what he brings to every roof inspection. We treat your Owens Corning roof as a system, not a surface. Decking, underlayment, flashing, ventilation, and shingles all have to work together, especially on Van Nuys homes with original raised foundations and aging framing. We deliver a written price before any work starts, and every job carries a 365-Day Done Right Promise in writing. Call (213) 632-5711 and you’ll reach a live person, not a phone tree.

Common Owens Corning Construction Problems We Solve in Van Nuys
- Granule loss on older Owens Corning Supreme shingles. Van Nuys summers push roof temperatures past 140°F on south-facing slopes, and Supreme shingles from the 1990s and early 2000s shed granules faster under that kind of sustained heat. You’ll see bald gray patches where the asphalt is starting to oxidize. Left alone, those spots let UV light chew through the mat, and the next rain finds its way in.
- Wind-lift and broken seal strips on Owens Corning Duration shingles. Santa Ana winds hit Van Nuys in fall and early winter with gusts that can exceed 50 mph. Duration shingles use an engineered sealant strip, but on shallow-pitch 1950s ranchers the wind gets under the shingle edge and snaps that seal. The shingle doesn’t tear off; it lifts and slaps, which breaks more seals down the row.
- Cracked ridge lines where Owens Corning ProEdge hip and ridge was installed over old underlayment. We see this on Van Nuys homes where a previous contractor put new ridge shingles over brittle, sun-baked underlayment from the original build. The ridge flexes with decades of thermal cycling, the underlayment can’t move with it, and cracks open up that funnel water straight into the attic.
- Moisture telegraphing around original raised-foundation vents. Many Van Nuys ranchers have crawl-space vents cut into the roofline or gable ends. When the underlayment around those vents fails, Owens Corning shingles above them start to telegraph moisture into the decking. You won’t always see a ceiling stain; you’ll smell it first, or notice the shingles cupping.
- Compressed attic insulation under Owens Corning roofs. This one shows up when we tear off a roof,not before. Original Owens Corning fiberglass insulation in 1950s Van Nuys attics is often compressed to less than half its labeled R-value by decades of heat, rodent activity, and owners shoving boxes on top of it. That means your new Owens Corning roof is working harder than it should, and your cooling bills show it.
Owens Corning Service in Van Nuys: What Local Conditions Mean for Your Equipment
Here’s something you won’t read on a generic Owens Corning page. Van Nuys sits on flat, sandy-loam lots that were developed fast during the post-war boom, and the building codes of that era didn’t anticipate the additions and remodels that came later. Many homes still have their original Owens Corning fiberglass insulation, never upgraded for the square footage that got tacked on during Van Nuys bathroom remodeling and additions in the 1970s and 1980s. When we tear off a roof on a Van Nuys rancher, we routinely find attic insulation compressed to less than half its rated R-value, packed down by decades of heat and the kind of rodent traffic that loves a warm valley attic. That’s not a roofing problem in isolation. It changes how we spec the underlayment, how we position attic ventilation, and whether we recommend adding insulation before the new Owens Corning shingles go down. On a 1954 rancher off Vanowen Street, our tech found Owens Corning Supreme shingles with sealant strips melted into the underlayment from years of summer heat, causing a 12-foot wrinkle that leaked into the living room. We tore off the old roof, replaced the rotted decking around the original raised-foundation vent, and installed Owens Corning Duration shingles with a high-temperature underlayment rated for this valley’s dry heat. That’s the kind of job you can’t plan for from a brochure.
Owens Corning Models & Products We Service in Van Nuys
We work on all the major Owens Corning shingle lines you’ll find on Van Nuys roofs: Owens Corning Duration® Series, Owens Corning Oakridge®, Owens Corning Supreme®, and Owens Corning ProEdge® hip & ridge. When we’re restoring a roof to original spec, we use genuine Owens Corning shingles and accessories sourced from local suppliers in the San Fernando Valley. But we don’t default to OEM for everything. Van Nuys’s expansion-contraction cycles, with summer heat followed by cold snaps and Santa Ana wind events, demand underlayment and flashing that can move. When an aftermarket high-temperature underlayment or a wider flashing profile will outlast the original spec, we say so and explain why. We also install gutters and accessories that integrate with Owens Corning roof systems, and we’re honest when something is beyond repair. If the decking or insulation is water-damaged, we replace only what’s needed. We don’t sell full tear-offs on homes that need a targeted fix.

AfterOwens Corning Service Pricing in Van Nuys

What you’ll pay depends on the size of the roof, the Owens Corning line you choose, the condition of the decking and underlayment, and whether we’re repairing or replacing. Here are the ranges you should expect for Van Nuys work:
| Service | Typical Van Nuys Price Range |
|---|---|
| Roof Replacement (Owens Corning Duration shingles) | $8,000 – $20,000 |
| Roof Repair (Owens Corning shingle replacement) | $400 – $1,800 |
| Gutter replacement with Owens Corning-compatible flashing | $3,500 – $9,000 |
The biggest cost driver is the decking. On 1950s Van Nuys ranchers, we often find rotted sections around vents and eaves that have to be replaced before new Owens Corning shingles go on. That’s real material and labor, and you’ll see it itemized in the written estimate. What you won’t see is a surprise invoice at the end. The written price you get before work starts is the price you pay, unless you ask us to add scope. Call (213) 632-5711 for an exact quote on your Owens Corning roof, free of charge.

FAQs – Owens Corning Construction in Van Nuys
Duration shingles are engineered for high-heat climates and do not warp under normal Van Nuys summer conditions. The failure we see isn’t warping; it’s seal-strip separation after repeated Santa Ana wind events. The shingle itself holds its shape, but the wind gets under the edge and breaks the adhesive bond. Proper installation with the right nail pattern and a high-temperature underlayment makes a measurable difference. Call (213) 632-5711 if you suspect seal failure on your roof.
Color matching a 60-year-old shingle is hard, and we won’t pretend otherwise. Owens Corning Supreme is still made in several colors, but decades of sun fade the original shingles lighter than any new bundle. We’ll bring samples to your Van Nuys home and show you the closest current match before we touch anything. Sometimes the honest answer is that a partial repair will be visible, and a full replacement of that roof plane is the better call. Call (213) 632-5711 and we’ll tell you straight.
Santa Ana winds hit Van Nuys from the northeast at high speed, which is the opposite direction of our normal weather. That pushes rain and debris under shingle edges, gable vents, and ridge lines in ways a standard rainstorm never does. If your Owens Corning roof leaks only during wind events, you likely have broken seal strips or cracking along the ridge and eaves. It’s a repairable problem if caught early. Call (213) 632-5711 to schedule an inspection.
Yes, with a caveat. Shingles don’t care about your foundation type, but the way your house moves during and after a seismic retrofit does. Raised foundations on Van Nuys’s sandy-loam lots flex more than slab foundations, and that flexing travels up through the walls to the roof deck. We’ve seen retrofit projects crack ridge lines and pop seal strips on otherwise sound Owens Corning roofs. When we know a retrofit is planned, we factor that movement into how we spec underlayment and attachment. Call (213) 632-5711 and tell us what’s going on with your foundation.
Owens Corning Duration is our usual recommendation for low-pitch Van Nuys roofs, because its SureNail strip and reinforced nailing area hold better under wind lift than Supreme on shallow slopes. Heavy tree debris, which is common on Van Nuys streets with mature ficus and magnolia, means you also want a wider drip edge and clean gutters, because debris dams force water back under the shingle edge. We’ll spec the full system when we inspect. Call (213) 632-5711 for a free estimate.
