Owens Corning Construction in Colma, CA | Gold Star Contractors
Gold Star Contractors provides independent Owens Corning roofing installation and repair across Colma, CA 94015. We’re not a manufacturer-affiliated or authorized dealer, and we’ve never claimed to be. What we do bring is years of hands-on experience with Owens Corning shingles and underlayments on the exact kinds of buildings Colma actually has: mausoleums, columbaria, dealership showrooms, and cemetery support structures along Junipero Serra Boulevard. If you need a roof that holds up to Colma’s fog and wind-driven moisture, call us at (833) 382-8544 for a free estimate.
Why Colma Residents Choose Us for Owens Corning Service
Owens Corning makes a genuinely good shingle. But a shingle is only as good as the deck, underlayment, and flashing beneath it. In Colma, where damp air rolls in off the Pacific nearly every afternoon, the details matter more than the product name on the wrapper, which is why we offer Owens Corning service in South San Francisco and surrounding areas. Our crews have torn off enough failed roofs here to know exactly where Owens Corning systems break down first: eave edges, valleys, and penetration boots where wind-driven rain finds every gap.
Noel Carranza, our owner and our General Contractor in Colma, started in concrete and finish carpentry before moving into full-scope contracting. He’s seen the same pattern on Colma commercial buildings for years: someone installs a decent Owens Corning shingle over bargain flashing and standard fasteners, and the fog does the rest. We don’t do that. We match Owens Corning shingles and underlayments with corrosion-resistant flashing and fasteners rated for coastal conditions. One call, done right, that’s the only way we know how to run a job.

Common Owens Corning Construction Problems We Solve in Colma
- Granule loss and mat deterioration on south- and west-facing slopes. Persistent summer fog and damp air accelerate granule shedding when attic ventilation is inadequate. We see this constantly on older dealership roofs along Junipero Serra Boulevard. The shingle surface looks thin, the gutters fill with granules, and streaks appear on the wall below.
- Rusted fasteners and flashing at eave edges and valleys. Colma’s wind-driven rain is relentless, especially on cemetery buildings with low-slope sections and multiple penetrations. Standard galvanized flashing corrodes quickly here. Rust streaks run down from the roof line, and shingles uplift at the corners.
- Sealant failure at terminations and penetration boots. Mausoleum and columbarium roofs often have low-slope sections tied into shingle courses. The transition points are where sealant fails first, letting moisture track back under Owens Corning shingle courses and into the conditioned space below.
- Shingle cracking and nail pops from flexing decking. On older Colma structures, original decking is often spaced boards or thin sheathing. It flexes under foot traffic and thermal movement, causing Owens Corning shingles to crack and nails to pop even when the shingle itself is sound.
- Improper low-slope application. Owens Corning shingles are not designed for flat or near-flat roof sections. We regularly find shingles laid on low-slope mausoleum sections where they should have been a membrane system or at minimum a specialized low-slope detail. The result is chronic leaking at the transition.
Owens Corning Service in Colma: What Local Conditions Mean for Your Equipment
Here’s what makes Colma different from every other town we work in, and it’s not subtle. Colma’s building department focuses almost exclusively on the BART corridor and the Junipero Serra Boulevard commercial frontage. That means nearly every Owens Corning roof we permit here is for a dealership, mausoleum, or cemetery support building rather than a house. The inspection sequence is built around commercial tenant-improvement timelines, not residential re-roofs. If you own or manage one of these buildings in Colma, your Owens Corning roof work will be permitted and inspected differently than Owens Corning in Pacifica, Daly City, or Broadmoor. We know the Colma city building department’s commercial process, we know which inspection points they’ll hit, and we can sequence the work so you’re not left with an open roof waiting on a Tuesday afternoon inspection slot. That’s the kind of thing you only learn by doing this work in Colma, not by reading a shingle brochure.
Owens Corning Models & Products We Service in Colma
We install and repair the full range of Owens Corning architectural and traditional shingles, including Oakridge® architectural shingles, Duration® Series architectural shingles, and Supreme® traditional 3-tab shingles for buildings where that profile matches existing work. We also stock and apply WeatherLock® self-adhering underlayment, which we strongly recommend on Colma’s damp, fog-prone roof decks. When it comes to parts, we use manufacturer-specified or equal-quality accessories: corrosion-resistant flashing, stainless fasteners, and proper ventilation. If a roof is repairable within warranty-compatible Owens Corning components, we repair it. If the decking or flashing is broadly compromised, we recommend replacement rather than layering new shingles over failing layers. That’s not upselling. That’s protecting the Owens Corning product from early failure.

FAQs — Owens Corning Construction in Colma
No, and we’ll tell you that before you spend a dime. Owens Corning shingles are not rated for flat or near-flat roof sections. On Colma mausoleum and columbarium buildings with low-slope sections, we either tie into a proper membrane system or recommend an appropriate low-slope detail that keeps the Owens Corning shingles on the sloped portions and a compatible membrane on the flat sections. Forcing shingles onto a flat roof is how you get chronic leaks. Call (833) 382-8544 and we’ll tell you honestly what your roof needs.
Colma’s fog belt means persistent moisture, damp decking, and wind-driven rain that shortens the life of standard flashing and fasteners. Owens Corning shingles themselves hold up well when installed correctly, but the accessories matter more here. In Colma, we use corrosion-resistant fasteners and flashing at every eave, valley, and penetration because that’s where fog-driven moisture does its damage first. Inland, standard galvanized flashing might last twenty years. In Colma, it’s a rust streak waiting to happen.
Yes, and Colma’s permit process for commercial buildings runs differently than a homeowner re-roof. The city building department focuses on the BART corridor and Junipero Serra Boulevard commercial frontage, so your Owens Corning roof replacement on a dealership or cemetery building will go through commercial review and inspection timelines. We handle the permit application, pull the permit when approved, and schedule inspections so your roof isn’t left open longer than necessary. Call (833) 382-8544 for details specific to your building.
We use WeatherLock® self-adhering underlayment on Colma roofs whenever possible. Its self-adhering membrane seals around fasteners and provides a waterproof barrier at the eaves, valleys, and penetrations where wind-driven rain does the most damage in Colma. On older buildings with gapped decking, it’s essentially a second line of defense under the Owens Corning shingles. For a deck that’s been exposed to years of fog, it’s the difference between a roof that lasts and a roof that leaks at the first winter storm.
Yes, in most cases. Owens Corning maintains consistent color lines across their architectural and traditional shingle families. If we know the shingle line (Oakridge®, Duration®, or Supreme®) and the color name, we can typically match it. If the roof is old enough that the shingle has faded or the line has been discontinued, we’ll bring samples to the site and match as close as the Owens Corning range allows. For Colma cemetery buildings where aesthetics matter to district boards, we’ll document the match before ordering. Call (833) 382-8544 to schedule a match review.
