CertainTeed Roofing: The San Francisco Owner’s Guide
Most CertainTeed roofing issues in San Francisco come down to one of three things: a failed seal on a shingle, a cracked flashing point, or moisture that found its way under the underlayment near a roof penetration. Installed repair costs typically run $470 to $2,125 depending on what failed and how much of the surrounding field needs to come up. If you’re seeing water stains on a ceiling, granule grit in a gutter, or a shingle in the yard after a wind event, you’re probably looking at a repair, not a full replacement, and we can match OEM or equivalent parts to your exact CertainTeed line.
At Bradford Remodeling Co San Francisco, we work with CertainTeed product lines regularly. We’re an independent service provider, not a CertainTeed affiliate, but our crews carry the common CertainTeed-compatible repair components on the truck so most residential repairs are done in a single visit. The first step is knowing which CertainTeed product you have, so let’s sort that out before you spend money.
Which CertainTeed Models This Applies To
CertainTeed has several active shingle and accessory lines, and each uses slightly different fastening and seal-strip specs. The main residential lines we see in San Francisco:
- Landmark series – the workhorse architectural shingle. Landmark, Landmark Pro, and Landmark Premium all use the same basic exposure dimensions but the Premium is thicker and carries a heavier wind rating. If your roof is older, it’s usually Landmark or Landmark Pro.
- Presidential Shake – the thick, dimensional shake-look product. Repairs on this line require matching the specific color lot more carefully because the shadow bands make mismatches obvious.
- X T 25 / X T 30 – the 3-tab line, now less common on newer roofs but still on thousands of San Francisco homes built in the 1990s and early 2000s.
- Highland Slate – a premium slate-look product seen more often on higher-end remodels in neighborhoods like Presidio Heights and St. Francis Wood.
To identify exactly what you have, check the underside of a leftover shingle bundle in the garage, or look at the original roofing permit if it’s still in your records. The bundle wrapper carries a product code and color name. If you don’t have a bundle, we can identify most CertainTeed lines from a clear photo of the exposed shingle course and the butted edge. The compatibility gotcha most homeowners don’t know: CertainTeed color lots drift slightly between production runs, so a patch done with the same color name but from a different lot can be visible under certain light. We order from the current production run and, where exact match matters, we’ll say so before we start.

Signs Your CertainTeed Roofing Is Failing
- Granule loss collecting in gutters or downspout elbows. Every asphalt shingle sheds some granules early in life, but heavy accumulation after year five usually means the shingle surface is oxidizing faster than it should. In San Francisco’s fog belt, that means moisture is holding on the shingle longer than the manufacturer’s dry-cycle assumptions.
- Curling or lifting shingle corners. This is usually a sign the seal strip has failed and wind is getting under the edge. Once a corner lifts, the next wind event works a bigger section loose. On exposed roofs in the Outer Sunset or Twin Peaks, one lifted corner becomes a torn shingle inside a season.
- Water staining on ceiling drywall, usually near a chimney, vent pipe, or valley. Roof leaks rarely show up directly under the roof damage. Water travels along sheathing and trusses before it finds a drywall seam to darken. The real breach is often six to twelve feet upslope from the stain.
- Dark streaks or moss at the eaves on shaded roof planes. San Francisco properties with big trees or north-facing roof slopes hold moisture long enough for moss to anchor into the granule surface. Moss roots work into the shingle mat and freeze-thaw cycles don’t help. We don’t power-wash shingles; we treat and remove mechanically where the shingle itself is still sound.
- Missing shingles after a storm. This is the obvious one, and the one where delay costs real money. An exposed section of underlayment is water-permeable and every day of exposure in San Francisco fog shortens the life of the sheathing under it.

AfterReplacement Cost & What’s Included
For a typical CertainTeed shingle repair in San Francisco, expect $470 to $2,125 installed. Here’s how that range breaks down:
| Scope | Typical Installed Range | What’s Included |
|---|---|---|
| Single shingle replacement, easy access, single story | $470 – $710 | Matching shingle, sealant, labor, disposal |
| Multi-shingle repair around a penetration (vent, pipe, skylight) | $710 – $1,180 | Shingles, flashing inspection, sealant, labor, disposal |
| Flashing replacement at chimney or valley | $1,180 – $2,125 | New metal flashing, removed and reinstalled shingles, sealant, labor, disposal |
The range is driven by roof pitch, story height, and how far into the field the damaged area sits. A repair on a walkable low-pitch roof at the first story costs less than the same repair on a steep second-story plane. Every Bradford Remodeling Co San Francisco job gets a written price before work starts, and that number doesn’t move at the door. Parts and labor are itemized on the quote. The work is covered by the 365-Day Done Right Promise: if it fails inside a year, we come back and correct it at no charge.
DIY or Call Us?
You can safely do a few things before you call anyone. Walk the perimeter of the house with your phone camera and photograph the damaged area from the ground. Note how many shingles look affected, whether the damage is near a penetration or a valley, and which roof plane it’s on. Check the ceiling inside for staining and mark the spot with painter’s tape. That information makes our first conversation shorter and tells us what to bring.
What you shouldn’t do is get on the roof. CertainTeed shingles become extremely slippery when wet, which in San Francisco is most mornings. Falls from single-story roofs break bones; falls from upper stories kill. A professional crew works with fall protection, roof jacks, and proper anchors. We see more damaged shingles from homeowners walking on a roof to “just look” than from actual storms. Call (831) 610-5598 and we’ll come put eyes on it from the right position.
FAQs
Landmark architectural shingles typically carry a lifetime limited warranty that in real terms means 30 to 50 years depending on roof orientation and fog exposure. West-facing and fog-saturated slopes in the Outer Richmond and Outer Sunset often show meaningful wear in 20 to 25 years. The warranty covers manufacturing defects; it does not cover San Francisco’s damp-air oxidation pattern, which is an environmental wear issue, not a product failure. That’s why most of our work is repair of specific failed areas rather than full replacement.
Yes, if the shingle itself is intact and the issue is a broken seal strip, we can often re-adhere the shingle with a compatible sealant and move on. If the shingle has torn, cracked through, or lost its granule surface, it gets replaced. Patching over a fractured shingle just hides the problem under another layer of material. Call (831) 610-5598 and we’ll tell you which category yours falls into.
Most single-area repairs take two to four hours from setup to cleanup. Repairs around chimneys or valleys with flashing replacement can stretch into a full day. We schedule a specific arrival window, and the crew leaves the site clean with the damaged material hauled away. You won’t find shingle fragments in your landscaping when we’re done.
We keep common CertainTeed repair components on the truck: sealants, flashing stock, fasteners, and a rotating stock of the most common Landmark colors. Specific color lots for older roofs or Presidential Shake repairs usually require a supply-house order, which adds a day or two. We’ll tell you on the first call whether your repair is a truck-stock job or an order job, so you’re not waiting on a surprise.
