How CertainTeed Products Fail – and How We Fix Them

CertainTeed makes solid roofing products, but every product line has its failure patterns. We see the same issues repeat across San Francisco neighborhoods, from the Sunset to Noe Valley. Here’s what actually fails and what we do about it.

• Landmark shingle delamination in fog-heavy zones. The Landmark line is the most common CertainTeed shingle we service in San Francisco. In the Richmond and Sunset districts, persistent marine fog keeps shingles damp for hours each morning. That moisture works into the adhesive seal strip over time, and shingles start to curl or lift. We find the lifted tabs, replace the compromised shingles, and verify the underlayment hasn’t started wicking water. If the decking shows dark staining, we cut it out and patch with fresh plywood before re-shingling.
• Presidential Shake TL cupping from trapped heat. This triple-laminate line is thick and attractive, but it’s heavy. On older San Francisco homes with limited attic ventilation, heat gets trapped under the decking and bakes the shingles from below. The result is cupping at the shingle edges. We check ridge and soffit venting first. If airflow is poor, we recommend adding ventilation before replacing the cupped sections. Patching cupped Presidential Shake without fixing ventilation just means the new shingles cup too.
• Flashing failures at curb skylights and dormer walls. San Francisco has thousands of older homes with dormers and curb-mounted skylights. The step flashing and counter-flashing around these transitions is where CertainTeed roofs leak most often. The flashing itself isn’t always CertainTeed-branded; it’s whatever the original installer used. We strip back the shingles, inspect the flashing for rust-through and broken sealant, and replace it with new metal. Then we re-seat the shingles and check the water channel before we call it done.
• Field shingle cracking on steep Victorian pitches. Homes near Alamo Square and Pacific Heights often have steep roof planes. CertainTeed Landmark and Grand Manor shingles on these pitches can develop small stress cracks at the nail line. The fix is usually localized replacement, but we inspect the nail pattern underneath. If the original installer drove nails too high or used fewer nails than CertainTeed requires, the repair needs to account for that, or the same cracking returns next season.
• Granule loss that signals the end of service life. Granule loss on CertainTeed shingles doesn’t mean immediate failure, but it means the shingle’s UV protection is thinning. We see this on San Francisco roofs that are 18 to 22 years old. The telltale sign is asphalt-colored streaks on a roof that was originally charcoal or weatherwood. If granule loss is widespread, we tell you honestly: patching buys time, but a re-roof is the real fix. We’ll give you the price for both and let you decide with the numbers in hand.

Our CertainTeed Roofing Company Process

When you call Brennan Roofing Co San Francisco for CertainTeed work, here’s how the job runs, start to finish.

1. 1
   Call and schedule. A live person answers at (831) 318-8819. We book a time for a uniformed, background-checked technician to come out. You’ll know who’s coming before they arrive.
2. 2
   Rooftop inspection and diagnosis. Travis Oakley or one of our senior techs walks the roof, takes photos, and identifies the exact failure point. We check the shingles, flashing, underlayment, and decking in the affected area. We’ll tell you what needs fixing now, what can wait, and what doesn’t need any work. That’s the honest read.
3. 3
   Written price before any work starts. You get a line-item price on paper. No work begins until you’ve seen that number. If we think CertainTeed OEM shingles are the right call for color and texture match, we use them. If an aftermarket part does the job without any warranty impact, we’ll tell you that too and show you the cost difference.
4. 4
   The repair or replacement. We strip back the affected area, replace or repair the decking if needed, install new underlayment and shingles to CertainTeed’s installation spec, and re-seat all flashing. The job site gets cleaned up before we leave.
5. 5
   Water test and visual confirmation. We check the repair for proper drainage, nail placement, and seal strip contact. If we can water-test the area, we do.
6. 6
   Written guarantee. Every job is covered by the 365-Day Done Right Promise in writing. If the repair fails within one year, we come back and fix it at no charge.
