How Tamko Products Fail – and How We Fix Them

• Tamko Heritage shingle granule loss from Santa Ana wind cycles. Heritage is the line we see most often on San Diego homes built between 2005 and 2018. After repeated dry Santa Ana events followed by marine-layer moisture, the granule-to-asphalt bond weakens faster than it does in inland climates. You’ll notice dark streaks at the drip edge and excess granules in gutters. We fix this by replacing the affected slopes and checking the decking beneath, because granule loss here is usually an early warning, not just a cosmetic issue.
• Tamko StormFighter nail pull-through at the eaves. StormFighter is Tamko’s higher-wind line, and in Clairemont Mesa and Tierrasanta, we regularly see nails backing out at the low edge of the roof where uplift pressure is highest. The symptom is a wavy line of shingles near the gutter line. The fix is renailing with the correct fastener length and pattern, then sealing any exposed nail heads. We’ve done enough of these to know it’s a pattern, not bad luck.
• Tamko 3-tab (Elite) cracking in hard sun exposure. Older 3-tab Tamko roofs, especially south-facing planes in Chula Vista and El Cajon, crack along the cutout lines after 12 to 15 years of UV. Once a 3-tab cracks, water gets under the next course. We walk the roof to map every cracked shingle, then decide with you whether the repair should be shingle-scoped or whether a full reroof with a laminated Tamko line makes more sense on planes that far gone.
• Valley flashing corrosion near the coast. Any asphalt shingle roof in Ocean Beach, Point Loma, or Coronado is up against marine air. But Tamko’s valley metal, when paired with cheaper fasteners, can corrode at the nail point within a decade. The symptom is a rusty streak running down the valley into the gutter. We replace the valley with corrosion-resistant metal, not a paint-over, and we inspect the underlayment below because rusty valleys leak slowly for years before anyone notices a ceiling stain.
• Ridge cap detachment on older Tamko installations using non-Tamko caps. A lot of San Diego homes got Tamko field shingles with off-the-shelf ridge caps from whatever supplier was cheapest that week. Those mismatched caps don’t seal with the same thermal bonding, and wind peels them back. The fix is straightforward: strip the old caps, install Tamko-compatible or properly matched ridge caps, and seal the hips. It’s a small repair that prevents a much larger leak.

Our Tamko Roofing Company Process

1. 1
   You call, a person answers. No voicemail tree. We take your address, the age of the roof if you know it, and what you’re seeing.
2. 2
   We send you the technician’s name and photo before the visit. When they arrive, they badging in with a photo ID. No guessing who’s at the door.
3. 3
   We diagnose on the roof, not from the driveway. Our tech walks every slope, checks the flashing and underlayment in the problem area, and documents what they found with photos you get to see.
4. 4
   You get a written price before any work. That price covers the parts decision too. We’ll tell you whether OEM Tamko stock or a quality aftermarket equivalent makes sense for your roof’s age and your warranty goals. No surprises on the invoice.
5. 5
   We do the repair or replacement, then test it. Water test on the repaired section, fastener check on surrounding courses, and a cleanup pass with a magnet for stray nails.
6. 6
   You get the 365-day guarantee in writing. If the repair fails within a year, the second visit is free. Grant Whitlock walks every job before we call it done.
