GAF Construction in Colma, CA | Daly City Construction
GAF construction service in Colma means roofing work built around fog, damp, and drainage, not just shingles. We’re Daly City Construction, and we repair and replace GAF Timberline and EverGuard systems across Colma’s 94015 ZIP, from small residential homes to the cemetery and mortuary buildings that define this town. We also offer Daly City GAF service for nearby properties. The one thing that sets our GAF work here apart: we coordinate every roof and gutter job with the site’s actual drainage and plot reality, because in Colma, runoff has nowhere casual to go. Call (866) 505-5254 for a free estimate.
Why Colma Residents Choose Us for GAF Service
Noel Cabrera, our owner, grew up in the Westlake district of Daly City and trained in construction technology at City College of San Francisco before putting in years on residential and light commercial jobs across San Mateo and San Francisco counties. That background matters in Colma because he knows what persistent coastal fog does to a roof deck, a flashing seam, and a gutter run. We’re an independent contractor, not a GAF-authorized dealer, and that independence lets us match the repair to the roof rather than to a sales target. When a GAF Timberline field in Colma shows granule loss on the north slope, we tell you whether a targeted repair holds or whether the mat is too far gone and replacement makes more sense. Our GAF sales & service work covers the full scope: roof repair, roof replacement and installation, and gutters and accessories, with factory GAF ridge cap, starter, and underlayment used wherever the existing field is GAF.

Common GAF Construction Problems We Solve in Colma
Here’s what we see repeatedly on GAF roofs across Colma, and why the local conditions make each one worse.
- Fog-belt moss and biological growth on Timberline fields. Colma sits in the fog belt just inland of Daly City, with damp conditions most of the year. North-facing shingle fields that rarely dry out grow moss that lifts granules and holds moisture directly against the mat. We remove the growth carefully and repair the affected courses before the mat itself starts breaking down.
- Granule loss and algae streaking from year-round damp. Older Timberline shingles in Colma lose granules faster than the same shingles would in a drier climate. Once the fiberglass mat shows through, the shingle is done. We inspect for this specifically because it’s the difference between a $600 repair and full replacement.
- Wind-lifted and creased shingle tabs after coastal storms. Storms off the Pacific push wind and driving fog-mist under shingle tabs at ridges and eaves. Failed sealant strips let tabs lift, then crease. We re-secure what’s sound and replace what isn’t, using GAF accessories that match the field.
- Flashing and penetration failures at roof transitions. Chapel, columbarium, and mortuary roofs in Colma have scuppers, wall transitions, and equipment penetrations where water ponds. Sealant and step flashing fail under constant moisture, and we re-flash those areas before the leak reaches the structure.
- Gutter runs that don’t tie into landscape drainage. Cemetery and mortuary buildings sit on landscaped grounds with their own drainage systems. A gutter that dumps runoff at the wrong spot undermines monuments, saturates soil, or floods vault areas. We reset runs so water feeds the grounds’ system, not the foundation or a burial plot.
GAF Service in Colma: What Local Conditions Mean for Your Equipment
Colma is a town of just over 1,500 living residents, but more than 1.5 million burials across roughly 17 cemeteries. That means most construction here is cemetery or mortuary infrastructure: columbaria, mausoleums, chapels, utility buildings, and the drainage systems that keep landscaped grounds from turning into a marsh. For a GAF roof, that changes the whole job. The buildings are low-rise, often flat or low-slope, which pushes the choice toward GAF EverGuard TPO or Liberty SBS rather than Timberline architectural shingles. And because grave plots, vaults, and burial records are effectively permanent, any digging for gutter runs, downspout tie-ins, or drainage work has to be coordinated with the individual cemetery operator and their plot maps, not just the city. You don’t stage materials or trench a downspout line without knowing what’s under the soil. We’ve done this enough to walk the plot map before we unload a single bundle.
GAF Models & Products We Service in Colma
We service GAF Timberline HDZ architectural shingles, Timberline Natural Shadow, EverGuard TPO single-ply for low-slope and flat roofs, and Liberty SBS self-adhered membrane. On Colma’s residential streets, Timberline is the common field, and we match repairs with factory GAF ridge cap, starter, and underlayment so the system stays consistent. On the low-rise chapel and mortuary buildings, EverGuard TPO is what we install and repair most often. We keep standard GAF accessories and compatible aftermarket components stocked for fast turnaround across the 94015 ZIP, and we only use aftermarket parts where they meet or exceed spec. If the roof is GAF, the repair stays GAF.

AfterGAF Service Pricing in Colma
Here’s what GAF work in Colma typically runs. Costs shift with slope, access, the condition of the deck, and whether we’re coordinating with a cemetery operator on drainage.
| Service | Price Range |
|---|---|
| Roof Repair | $400 – $1800 |
| Roof Replacement & Installation | $8000 – $20000 |
| Metal Roof Installation | $15000 – $40000 |
| Tile Roof Repair | $600 – $2500 |
Repair cost depends on how far the fog damage has spread and whether we’re re-flashing penetrations or replacing field shingles. Replacement cost depends on roof size, tear-off work, and deck repairs once we see what’s underneath. Every estimate is a written line-item quote, and we walk the roof with you before we put numbers on paper. Call (866) 505-5254 to schedule a free estimate.

FAQs – GAF Construction in Colma
Fog and damp. Colma sits in the fog belt just inland of Daly City, and north-facing shingle fields rarely dry out enough to stop moss and algae from establishing. The same conditions drive GAF repair in Broadmoor and other nearby fog-belt communities. The growth holds moisture against the granule layer, which accelerates granule loss and shortens the life of the mat. We remove moss carefully and repair the affected courses so the roof sheds water cleanly again. Call (866) 505-5254 if you’re seeing green on the north slope.
Yes, and we do it regularly. The difference is coordination. Cemetery and mortuary grounds have their own drainage and irrigation systems, and any roof or gutter work has to tie into that and be cleared with the cemetery operator, not just the city. Runoff needs to feed the landscape drainage, not pool at a vault wall or undermine monuments. We walk the plot map before staging.
GAF’s material warranty covers manufacturing defects in the shingles themselves, not the labor or installation. An independent contractor doing repairs doesn’t void the material warranty, but GAF’s enhanced warranties, like wind or workmanship coverage, only apply when an authorized GAF contractor installs the full system. We’re not GAF-authorized, and we don’t claim to be. We tell you plainly what your warranty covers and what it doesn’t. Call (866) 505-5254 and we’ll help you sort it out.
For a flat or low-slope roof, EverGuard TPO or Liberty SBS self-adhered membrane is the right call. Timberline architectural shingles are built for sloped residential fields. Many of Colma’s chapel, mortuary, and utility buildings are low-slope, so ponding water is the real enemy, and that’s what EverGuard is designed to handle. We’ll look at the roof’s slope and drainage and recommend the GAF product that actually fits.
Look for granule loss, exposed fiberglass mat, moss that’s lifting shingle courses, and sealant failure at ridges and eaves. If the mat is exposed across large areas or the shingles are creased and lifting, replacement is usually the honest answer. If damage is isolated to a few courses or a flashing detail, a targeted repair holds. We inspect and tell you straight, even when repair is the cheaper option.
