How CertainTeed Products Fail – and How We Fix Them

CertainTeed makes solid material, but San Diego’s particular combination of UV exposure, marine air, and zero-frost winters creates failure patterns we see over and over. Here’s what actually happens on CertainTeed roofs in this city, and what we do about it on a replacement.

• Landmark and Landmark Pro granule loss on south-facing slopes. San Diego sun is relentless on the southern exposure. After 12 to 15 years, we regularly see Landmark shingles shedding granules faster than the manufacturer’s typical wear curve, especially on homes in Clairemont and El Cajon where there’s little tree cover. The asphalt underneath oxidizes, the shingle gets brittle, and leaks follow. On replacement, we upgrade to Landmark Pro or move to Presidential for better UV resistance, and we inspect decking under the granule-bare zones carefully.
• Presidential Shake shingle curling at the eaves. Presidential Shake is a thick triple-laminate shingle, but its weight and stiffness make it prone to lifting at eave edges when the original installer skipped starter-strip replacement or used the wrong drip edge profile. In coastal neighborhoods like Ocean Beach and Point Loma, the daily marine moisture cycle accelerates this. We pull the eave rows, check the drip edge and starter course, and reset the profile so the new shingles lay flat the day they go on.
• CertainTeed flat-roof membranes shrinking at parapet walls. CertainTeed’s Flintlastic modified bitumen lines are common on San Diego flat roofs, especially the post-war bungalows around North Park and Normal Heights. After several years of direct sun, the membrane can shrink and pull away from parapet flashings, opening a seam at exactly the spot where water ponds. When we re-roof a flat section, we always install new cant strips and a taller base flashing than what was there before, because the old detail usually wasn’t built for San Diego heat.
• Ventilation-related failure on Landmark and XT 25 roofs. San Diego attics get hot, and under-ventilated CertainTeed roofs age faster than they should. We see XT 25 and older Landmark roofs in Santee and Lakeside where the shingles have cooked from the underside, leading to premature cracking and tear strength loss. Before we ever lay new shingles, we calculate intake and exhaust ventilation with a simple visual equation: 1 square foot of vent per 150 square feet of attic floor. Most older San Diego homes need more ridge or soffit ventilation, not less.
• Flashing failures around skylights and chimneys on XT 30 roofs. The XT 30 line was a budget-friendly CertainTeed shingle widely used on 1990s tract housing in Mira Mesa and Rancho Peñasquitos. The shingles themselves usually hold up, but the step flashing and counter-flashing installed alongside them was often bare galvanized metal that corrodes in coastal air. We replace these flashings with aluminum or stainless step flashing and proper counter-flashing on every CertainTeed roof replacement, regardless of how the original was done.

Our CertainTeed Roof Replacement Process

Here’s how a CertainTeed replacement works when you call Tilehurst Roofing San Diego.

1. 1
   Call and get a real person. You call (619) 393-3877 and one of us answers, day or night, weekends included. We schedule a roof inspection at a time that works for you, and we show up in the window we promised.
2. 2
   We inspect the roof and write the price. Greg Holloway or one of our senior techs walks the roof, takes attic photos, checks the decking, the underlayment condition, the existing ventilation, and every flashing point. Then we write a line-item price and hand it to you before any ladder work begins.
3. 3
   We decide on materials with you. For a CertainTeed replacement, we talk through Landmark versus Landmark Pro versus Presidential Shake versus Grand Manor, and what each costs per square installed. We also compare against GAF Timberline HDZ and Owens Corning Duration if you want a side-by-side. The product fits the home, not just what happens to be on our truck.
4. 4
   We tear off, inspect decking, and replace rotted sections. Every CertainTeed replacement includes a full decking inspection. In San Diego, we frequently find water-stained or delaminated OSB around valleys and eaves that the previous contractor covered instead of replacing. We show you photos before we deck over any bad section, and the cost of replacement decking is on the written estimate, not a surprise change order.
5. 5
   We install the new CertainTeed roof by the book. New underlayment, new drip edge, correct starter strip, nails in the right zones, ridge cap cut and set properly. We use CertainTeed’s installation specifications as our baseline, never our gut shortcuts. If there’s a warranty-required detail, it’s done.
6. 6
   Cleanup, final check, written guarantee. We run a magnet roller across the yard for old nails, blow out the gutters, and walk the roof with you one final time. Before the crew leaves, you’ve got a written guarantee on the replacement under our 365-Day Done Right Promise, plus the manufacturer warranty registration paperwork.

What CertainTeed Roof Replacement Costs in San Diego

Here’s what we quote on CertainTeed replacements in San Diego, in real dollars. These ranges reflect the typical home we see in this market, 1,500 to 2,400 square feet of roof area.

• CertainTeed Landmark (architectural shingle, full tear-off): $14,000 to $19,000
• CertainTeed Landmark Pro (full tear-off): $16,500 to $22,000
• CertainTeed Presidential Shake (premium, full tear-off): $22,000 to $30,000
• CertainTeed Flintlastic flat roof replacement (per square, installed): $850 to $1,200

What moves the price: roof pitch, number of existing layers being torn off, decking condition, skylight count, chimney and parapet flashing details, and whether you need new gutters. Steep roofs above a 7/12 pitch add labor because the crew works from brackets, not flat decks. If you want an exact number for your CertainTeed roof in San Diego, call (619) 393-3877 and we’ll walk the roof with you and write the price before any work starts. Estimates are free.
