If you’ve got a leak, curling shingles, or just a roof past its tenth birthday, call (669) 238-2101 and we’ll schedule an inspection that tells you what’s actually going on up there.

How CertainTeed Products Fail – and How We Fix Them

CertainTeed builds solid roofing, but like every manufacturer, they’ve got known weak points that show up in San Jose’s specific climate. We’ve been on enough CertainTeed roofs across the South Bay to recognize these failure patterns before they become full-blown leaks. Here’s what we actually see:

• Landmark series granule loss at the 12-year mark. CertainTeed’s Landmark architectural shingles carry a strong reputation, but on San Jose homes with direct southern exposure, we routinely see accelerated granule loss starting around year ten to twelve. The asphalt oxidizes under long dry summers, the granules loosen, and bald spots form where the fiberglass mat starts showing. Our fix: we document the extent during inspection, map the affected slopes, and give you a repair-vs-replace comparison with real numbers before you spend a dollar. Some Landmark roofs are patchable. Many at this stage are not, and we’ll tell you straight.
• Presidential Shake/TL sealant breakdown at the keyways. Presidential Shake and Presidential Shake TL are thick, heavy shingles that look great on the larger San Jose lots, especially around Silver Creek and Evergreen. But they rely on asphalt sealant strips to lock down correctly, and after ten-plus years of heat cycling, those sealant strips dry out. We find shingles that have lifted at the corners but haven’t fully detached, which means wind can get under them during winter storms off the Santa Cruz Mountains. During inspection, we physically lift a sample of shingles at the keyways to test sealant adhesion. If they’re failing, we re-seal or replace the affected shingles using CertainTeed-compatible sealant, which preserves your warranty position.
• Grand Manor XT tear-out complexity on steep pitches. Grand Manor XT is a slate-look shingle we see on higher-end San Jose homes, particularly in the hills around Los Gatos and Saratoga. The problem isn’t the shingle itself, it’s the repair. Because of the heavy two-layer construction, matching a Grand Manor XT roof for a partial repair requires exact color-lot matching and careful layering, or the patch stands out like a bad haircut. Our inspection records the color lot and production batch if legible on the bundle labels in your attic or garage, so if we do need to source replacement pieces, we’re ordering the right lot from the start.
• Flintlastic SA membrane splitting at parapet transitions. On flat and low-slope portions of San Jose homes, certainteed’s Flintlastic SA system is common. Our inspectors watch specifically for splitting at the parapet wall transition, where the membrane bends ninety degrees. San Jose’s temperature swings cause thermal movement, and over time, the membrane at that corner cracks. You won’t see it from the ground. We’ll find it during inspection because we’re up there with a moisture meter and we’re checking every transition by hand. Small splits get a proper CertainTeed-compatible repair. Large splits mean the membrane has reached the end of its service life.
• WinterGuard underlayment failures beneath older certainteed installs. CertainTeed’s WinterGuard is a good ice-and-water shield product, but we’ve torn off enough San Jose roofs to see what happens when it’s not installed properly. In the flat sections near drains and scuppers on certainteed low-slope systems, incorrectly-lapped WinterGuard lets water track sideways. The symptom is a ceiling stain that appears nowhere near the actual leak, often showing up in the garage or a bedroom corner. During inspection, we trace the water path using infrared moisture detection, which is why our inspection reports include both the symptom and the source. The fix is almost always flashing correction plus a targeted membrane patch.

All these failure modes are specific to certainteed products. We’re not guessing. Travis Oakley learned the trade at Los Angeles Trade-Technical College and has spent years on San Jose roofs, enough to know that a certainteed inspection isn’t a check-the-box exercise. Tell me what you’re seeing and I’ll tell you what it actually means.

Our CertainTeed Roof Inspection Process

Here’s what happens from the moment you call, step by step. No surprises. No price changes at the door.

1. 1
   You call (669) 238-2101. A live person answers, around the clock, every single time. We ask what you’re seeing and schedule the inspection.
2. 2
   We show up inside the promised window. Background-checked, uniformed technician. You know exactly who’s on your roof. Before we set a ladder, we walk the interior looking for ceiling stains, attic moisture, and any sign that water has already found its way in.
3. 3
   We inspect the roof surface systematically, certainteed product by certainteed product. Shingle condition, sealant adhesion, flashing at penetrations and valleys, pipe boot seals, chimney counterflashing, and the underlayment at eaves where WinterGuard belongs. We test with a moisture meter where necessary, not just our eyes.
4. 4
   We identify every issue and photograph it. Each finding goes into a written report with photos, measurements, and a straight diagnosis: this fails now, this fails in two years, this is cosmetic. We don’t manufacture problems to inflate the invoice.
5. 5
   The written price goes on paper before any work starts. If the inspection finds repairs are needed, we give you a line-item quote that says exactly what we’ll do, what parts we’ll use, OEM vs quality aftermarket options where relevant, and what it costs. That number does not move at the door.
6. 6
   We make the repair, test it, and you get the 365-Day Done Right Promise in writing. Every repair and installation is guaranteed in writing for one full year, and if it fails within that period, we come back at no charge and make it right. Then we clean up and leave your property looking like we were never there, except the roof is squared away.

What CertainTeed Roof Inspection Costs in San Jose

Here are real numbers for the certainteed inspection and common follow-up repairs we perform in San Jose. These ranges cover most homes we inspect from Blossom Valley to Berryessa. Prices vary by roof size, pitch, accessibility, and which certainteed product is on the roof.

What moves the price on a certainteed job: roof pitch (anything steep adds setup time and safety rigging), multi-story access, and whether we need to color-lot match an older Grand Manor or Presidential roof. The inspection itself is priced honestly, and if you approve repairs on the spot, we credit a portion of the inspection fee toward the work. Call (669) 238-2101 for a free estimate and a written price before any work starts.
