Owens Corning Construction in Broadmoor, CA | Ashford Contractors
We provide independent Owens Corning repair in Colma and across Broadmoor, and the one thing that sets our work apart here is this: we detail every Owens Corning shingle and FOAMULAR insulation install to survive Broadmoor’s marine fog corridor and San Andreas fault-zone permitting, not just to meet the manufacturer’s generic spec. Broadmoor’s 1940s and 1950s stucco-over-wood-frame homes fail differently than newer construction, and we’ve opened enough fog-soaked attics and unpermitted additions to know exactly what fails and why. Call (877) 752-3868 for a free Owens Corning roof or insulation estimate in Broadmoor.
Why Broadmoor Residents Choose Us for Owens Corning Service
There is no shortage of contractors who can install an Owens Corning Oakridge shingle. But there is a short list of contractors who can tell you why that shingle is lifting at the hips on a 1952 Broadmoor ranch while the same shingle sits fine on a Foster City track home three miles east. The difference is fog, attic ventilation, and seismic flex in the roof plane. Glen Mossier, our owner, started his construction career learning materials science at Skyline College in San Bruno and has spent two decades pulling apart the specific ways Bay Area weather chews through roofing and insulation assemblies. That background shows up on every Broadmoor job we take.
We are an independent Owens Corning service provider, not a manufacturer-authorized distributor. That means when Owens Corning products are the right call, we source them and detail them to fit your existing structure. And when a different brand or an aftermarket component does a better job for your exact exposure, we tell you that too. For more on our broader material sourcing and service scope, see our Owens Corning sales & service page.

Common Owens Corning Construction Problems We Solve in Broadmoor
- Wind-driven fog lifting Oakridge and Duration shingle laps. Persistent summer fog off the San Bruno Gap pushes moisture sideways, not just downward. A poorly ventilated roof deck holds that moisture against the shingle underlayment, and laps start lifting within a few seasons. We see this most often where a prior re-roof was layered over old felt and trapped the damp in the deck.
- FOAMULAR insulation found waterlogged or moldy inside stucco walls. Broadmoor’s original stucco-over-wood-frame construction lets marine damp wick into wall cavities year-round. Improperly installed FOAMULAR without proper moisture seals and dew-point detailing absorbs that damp and stops performing. We open walls on nearly every Broadmoor remodel and find this more than half the time.
- Seismic flex popping nail heads and loosening granules. Broadmoor sits near the San Andreas Fault zone, and the older soft-story framing common in the tract homes here flexes the roof plane more than people realize. That flex opens nail heads at hips and dormers and causes granule loss you cannot fix by re-nailing alone. The deck movement has to be addressed first.
- Attic ventilation never upgraded to the existing roof pitch. Many Broadmoor homes have original 1950s venting that was barely adequate when the home was built. Today, with added insulation and tighter envelopes, that attic heat bakes Owens Corning shingles from below all summer, which shortens the serviceable life and magnifies fog-season condensation once the marine air returns.
- Stucco-wall flashing failures at roof transitions. Broadmoor roofs meet stucco walls at dozens of transitions on the original tract layouts. When those flashed transitions were never rebuilt properly, the first fog season pushes water behind the stucco and into the deck. We rebuild these transitions on most Owens Corning roof replacements we handle in Broadmoor.
Owens Corning Service in Broadmoor: What Local Conditions Mean for Your Equipment
Every Broadmoor project is permitted through San Mateo County rather than Daly City, and because Broadmoor sits in the San Andreas Fault zone, the County’s seismic plan check applies to roof and wall work. That is the detail no generic Owens Corning page ever mentions, and it changes how we approach a simple re-roof. A like-for-like shingle replacement across the Daly City line would not face the same seismic mandate. In Broadmoor, opening a wall or stripping to the deck routinely triggers the County’s requirement for cripple-wall bracing and foundation bolting. So a re-roof here is not just a shingle swap: it often becomes a partial structural upgrade, and the smart move is to plan for it from day one instead of letting a County inspector flag it mid-job. That is why we include a seismic assessment in every Owens Corning roof estimate we write for Broadmoor homes. Our service area for this work spans the full Broadmoor service area, including the tight infill parcels where access and staging require extra planning.
On a 1950s stucco ranch off the Daly City border near our South San Francisco Owens Corning service area, a homeowner’s Owens Corning Oakridge roof was losing granules and lifting at the hip. Our crew traced it to a fog-soaked, under-ventilated attic sealed over decades-old felt. We stripped to the deck, corrected the ventilation, rebuilt the flashed transitions at the stucco walls, and installed a fresh Oakridge assembly while bracing the cripple walls per San Mateo County seismic requirements. The homeowner got a dry attic and a roof that sheds the summer fog instead of drinking it.
Owens Corning Models & Products We Service in Broadmoor
We install and service the Owens Corning product lines that actually fit Broadmoor’s housing stock and climate: Oakridge and Oakridge Pro shingle roofing, Duration and Duration Premium shingle roofing, the Berkshire Collection for homeowners who want a more architectural profile, and Pink Fiberglas plus FOAMULAR rigid foam insulation for wall and attic upgrades. On parts, we use genuine Owens Corning shingles and insulation where the product line and warranty documentation matter, and quality aftermarket underlayment, edge metal, and flashing where they outperform the commodity version. The assembly’s water-shedding and ventilation details decide performance, not the brand stamp on the shingle.

It is the substrate work the home already needs: deck repairs from years of fog-driven moisture, ventilation upgrades, seismic bracing if the County plan check requires it, and rebuilt stucco-wall flashing. Our free estimate walks every Broadmoor client through these line items before any contract is signed, so there are no surprises when the first wall comes open. Call (877) 752-3868 to schedule yours.

FAQs – Owens Corning Construction in Broadmoor
Usually, yes. Because Broadmoor permits run through San Mateo County and the home sits in the San Andreas Fault zone, the County’s seismic plan check applies to roof and wall work that would not trigger the same review across the Daly City line. Re-roofing or opening a wall here routinely pulls in cripple-wall bracing and foundation bolting requirements. We build that assessment into every Owens Corning estimate in Broadmoor so you know before work starts. Call (877) 752-3868 for an exact scope on your home.
Fog. Broadmoor gets persistent summer fog, wind, and damp marine air off the San Bruno Gap, and that moisture pushes sideways into roof assemblies rather than just sitting on top. When attic ventilation was never upgraded to match the existing roof pitch, that moisture gets trapped against the underlayment and the underside of the shingle, and the roof degrades from both directions. Homes three miles east in Foster City do not get the same fog loading. That is why our Broadmoor roof work always corrects ventilation before the new Owens Corning shingles go on.
Yes, when the deck is sound and the damage is isolated. We repair rather than replace whenever possible, especially on Broadmoor homes where a full replacement may also trigger seismic requirements. But once a shingle roof is failing at the hips, valleys, or beneath a stucco wall that keeps leaking, full replacement is the honest call. Call (877) 752-3868 and we will give you a straight answer on which path your roof actually needs.
We install Oakridge and Oakridge Pro shingles, Duration and Duration Premium shingles, the Berkshire Collection, and Pink Fiberglas plus FOAMULAR rigid foam insulation. For Broadmoor specifically, we lean toward the Oakridge and Duration lines because they handle the fog-corridor moisture loads better when paired with proper ventilation, and FOAMULAR because it performs well in stucco wall cavities when detailed with correct moisture seals and dew-point placement.
A roof repair in Broadmoor runs $400 to $1,800, a full Owens Corning replacement runs $8,000 to $20,000, and a standing seam metal roof runs $15,000 to $40,000. Your exact number depends on deck condition, ventilation upgrades, seismic work, and how many stucco-wall flashed transitions need rebuilding. Call (877) 752-3868 for a free line-item estimate.
