Why San Fernando Residents Choose Us for CertainTeed Service
Ron Thibodeau, our owner, learned roofing the hard way, starting with his uncle’s contracting operation in Burbank and later studying building construction technology at Los Angeles Valley College. That background matters when you’re dealing with CertainTeed products on San Fernando homes. We’ve torn off enough cracked XT 25 shingles and sun-baked Flintlastic membranes in this city to know exactly what we’re looking at before we even climb the ladder.
We’re not a manufacturer-authorized CertainTeed dealer, and we’re upfront about that. What we are is an independent service provider with deep hands-on experience installing and repairing CertainTeed shingle and low-slope systems across the San Fernando Valley. We work for the homeowner, not the manufacturer. That means when we tell you a CertainTeed Landmark roof still has years left in it, or that a Flintlastic patch has failed for the third time and replacement makes more sense, you’re getting an honest assessment, not a warranty pitch. Fast response matters when you’ve got a leak, and we treat every San Fernando call with the urgency it deserves.

Common CertainTeed Roofing Problems We Solve in San Fernando
- Thermal cracking and brittleness in CertainTeed XT 25 three-tab shingles. San Fernando’s summer rooftop surfaces get brutally hot, and those post-war tract homes bake all day. Aged XT 25 shingles lose their flexibility, crack at the edges, and start breaking off in pieces. We see this constantly in the older blocks around the civic core.
- Granule loss and blistering on CertainTeed Landmark architectural shingles. When attic ventilation is inadequate, which is common in 1950s and 1960s San Fernando homes, rooftop temperatures spike even higher. Landmark shingles shed granules and blister faster under that kind of heat load. The shingles look thin and patchy, and you’ll find granules piling up in gutters.
- Seam separation and alligatoring in CertainTeed Flintlastic modified bitumen. Flat and low-slope roofs dominate San Fernando’s older housing stock. Flintlastic membranes that have been patched repeatedly and baked by the east Valley sun develop the classic alligator-skin cracking pattern. Seams pull apart, and ponding water finds every weak point.
- Flashing pull-away and fastener back-out over original skip sheathing. Many San Fernando homes still have their original skip sheathing under the shingles. Thermal expansion cycles work fasteners loose, and flashing pulls away from chimneys and walls. A leak in one spot is usually a warning sign of movement across the whole plane.
- Failed patches on layered flat roofs. We regularly find two or three layers of old roofing on San Fernando flat roofs, each patched by a different contractor at a different time. The patches fail at the seams, and the layers trap heat, accelerating the breakdown of whatever CertainTeed membrane is underneath.
CertainTeed Service in San Fernando: What Local Conditions Mean for Your Roof
Every San Fernando roofing job done by a contractor from outside the city starts with a learning curve. The city’s building department handles reroofing permits and inspections differently than neighboring jurisdictions, and here’s the crux: older flat and low-pitch roofs often trigger Title 24 cool-roof and seismic retrofit requirements during reroof. Even a modest CertainTeed Flintlastic patch can pull the whole assembly into a compliance review that an out-of-town roofer will miss. We’ve seen jobs stall at inspection because nobody flagged the cool-roof requirement before work started. If you own a home with a flat or low-slope roof in San Fernando, that changes the way you should think about repairs. A patch that ignores the compliance question can become an expensive do-over. Our team knows the city’s process, we know when the review gets triggered, and we factor that into every estimate so you’re not blindsided at the permit counter.
Last year, on a 1950s stucco bungalow near the civic core, we tore off three layers of failing CertainTeed XT 25 shingles that had cracked and curled from decades of valley sun. The decking showed heat damage and loose flashing at the chimney, so we replaced the rotted sheathing, installed CertainTeed RoofRunner underlayment, and finished with CertainTeed Landmark architectural shingles. The homeowner also qualified for a Title 24 cool-roof rebate through the city, which we helped document. That job is what San Fernando roofing actually looks like: layers of history, heat damage, and city requirements all colliding on one roof.

- Flashing repair: $300 – $700 depending on the number of penetrations and access difficulty

FAQs – CertainTeed Roofing in San Fernando
Heat failure in CertainTeed Landmark shingles shows up as blistering, which are small raised bumps where trapped moisture or volatile compounds expanded under extreme rooftop temperatures, plus granule loss concentrated along the sun-exposed slopes. Age-related failure looks more like uniform wear and curling at the edges. In San Fernando, where attic ventilation is often inadequate, heat-driven blistering appears years before age-related breakdown would normally set in. If your granules are piling up in gutters and the shingles look scalded on the south and west slopes, heat is the likely culprit. Call (866) 705-2978 and we’ll confirm it from the rooftop.
In San Fernando, a full reroof on a flat or low-slope roof generally triggers Title 24 cool-roof requirements, and yes, the city inspects for compliance. Even a large patch can pull the assembly into review depending on scope. Contractors who don’t work in San Fernando regularly miss this, and the result is a failed inspection and a redo. We factor compliance into every flat-roof estimate so the first inspection is the one that passes. Call (866) 705-2978 to get a compliant scope on paper before work begins.
Yes, if the XT 25 shingles are still flexible and the leak is isolated to a specific area, like flashing pull-away or a few cracked shingles, a targeted repair is usually the right call. But if the shingles are 15 to 20 years old and brittle from San Fernando heat, patching is often throwing money at a falling system. We’ll give you an honest repair-versus-replace assessment before we touch anything. Call (866) 705-2978 and we’ll put eyes on it.
For low-slope San Fernando roofs, CertainTeed RoofRunner underlayment works well as a secondary barrier under shingles, but for true flat or very low-slope applications, CertainTeed Flintlastic membranes are the appropriate primary surface. The distinction matters: underlayment is not a roofing membrane, and using it as one on a ponding-prone flat roof is a failure waiting to happen. We match the product to the pitch and the city’s compliance requirements, not to what’s left on the truck.
Original CertainTeed shingles from the 1960s are almost certainly discontinued, and after six decades they’ve outlived their design life several times over. We can match the profile and color closely with current CertainTeed products, but the honest answer is that a roof that old in San Fernando’s heat is a candidate for replacement, not patching. If you’re set on a repair, we’ll assess the structural condition of the skip sheathing first, because that often determines whether a repair is even safe to attempt. Call (866) 705-2978 for a straight answer.
