We provide independent CertainTeed shingle and membrane service across Van Nuys, from the 91406 tracts near the airport to the older apartment stock along Vanowen and Victory. The one thing that sets our CertainTeed work apart here is that we diagnose for Valley heat first. A roof in Van Nuys doesn’t age the way a roof in Santa Monica ages, and if the repair doesn’t account for that, it won’t last. Call (844) 966-3891 for a free estimate across Van Nuys, including 91470, 91482, 91496, and 91499.
Why Van Nuys Residents Choose Us for CertainTeed Service
We work on CertainTeed roofs across the San Fernando Valley every week, so we know how Landmark shingles and Flintlastic membranes actually behave under 100°F-plus heat, not just how they read in a product sheet. Noel Carrasco, our owner, learned roofing through the construction technology program at Santiago Canyon College and spent years on every roof type Southern California throws at a crew. That background shapes how we approach a CertainTeed roof in Van Nuys: we read the deck, the ventilation, and the existing material before we touch anything.
We are an independent CertainTeed service provider. We have no affiliation with, authorization from, or warranty relationship with CertainTeed. That independence matters, because we don’t have a brand quota to hit. If your Landmark field is sound and only the windward edge needs work, that’s what we’ll tell you. CertainTeed sales & service on our end means repair first, replacement when the numbers justify it.

Common CertainTeed Roofing Problems We Solve in Van Nuys
- Heat-baked Landmark tabs that won’t re-seal. West- and south-facing slopes in Van Nuys take direct afternoon sun for months at a stretch. The seal strips on CertainTeed Landmark architectural shingles lose adhesion as the asphalt oxidizes, so tabs lift at the first strong gust. We reset and re-seal where the field is still viable, or replace the windward course with matching Landmark when it isn’t.
- Flintlastic SA seam failures on flat and shallow-pitch additions. The 1950s tract homes all over Van Nuys have rear additions with almost no slope. CertainTeed Flintlastic SA is the right product for those sections, but when attic ventilation is undersized, heat builds under the membrane and blisters the seams. We pull and re-torch or re-set the failed laps and fix the ventilation so the patch doesn’t fail the same way next summer.
- XT 25 and XT 30 granule loss and thermal cracking. The original single-layer roofs on 1940s and 1960s homes around Van Nuys are often CertainTeed three-tab that has been baking for five or six decades. The granules are gone, the surface is cracked, and the felt underneath is often dust. We show owners what’s happening and give an honest answer on whether spot repair still makes sense.
- Wind-scoured ridge caps and lifted rakes west of the 405. After a Santa Ana event, homes in the older tracts west of the 405 often lose ridge caps and see lifted shingles along the rake edges, especially on roofs that were already brittle. We replace ridge caps with matching CertainTeed material and re-detail the eave and rake edges so the next wind event doesn’t peel the roof further.
- Ponding at scuppers on flat apartment roofs. Van Nuys has a lot of low-rise apartment buildings with flat or near-flat CertainTeed membrane roofs. When the scupper drains clog or the membrane laps pull apart, water ponds and finds the seam. We re-seal laps, clear and re-flash the scupper, and patch the membrane with Flintlastic rather than overlaying what doesn’t need it.
CertainTeed Service in Van Nuys: What Local Conditions Mean for Your Roof
Van Nuys sits in the San Fernando Valley, where summer temperatures routinely exceed 100°F. That heat bakes roofs from the top down and, on low-slope sections, from the underside up. Something specific follows from that. The shallow-pitch and flat roofs common in the 1940s through 1960s tract and apartment stock around Van Nuys fail from heat-driven seam and ponding problems far more often than from storm damage. When we get called to a CertainTeed Flintlastic roof in Van Nuys, it’s usually a seam pulling apart at a scupper, or membrane blistered where ventilation was never adequate. A coastal crew might see the same roof and think storm. In Van Nuys, it’s the heat. That changes the repair: we don’t just patch the visible split, we address why the membrane got hot enough to fail in the first place. If the roof can’t breathe, the next seam will open the same way.
After a Santa Ana wind event, it’s a different call. Homeowners west of the 405, especially in the older tract pockets, find lifted tabs and missing ridge caps on roofs that were already heat-fried. We were called to a 1950s tract home near the Van Nuys Airport side of 91406 after one of those events. The west-facing CertainTeed Landmark field had lifted tabs and missing ridge caps on a roof baked brittle by years of Valley heat. We pulled and reset the windward course, replaced the ridge caps with matching Landmark, and re-nailed the loose eave edge. The owner didn’t need a full replacement. The roof needed its edge detailed. That’s the kind of call we make here constantly.
CertainTeed Models & Products We Service in Van Nuys
We repair and replace the CertainTeed lines most common on Van Nuys homes: Landmark architectural shingles, XT 25 and XT 30 three-tab shingles, Flintlastic SA self-adhered modified bitumen for low-slope sections, and Presidio and Symphony concrete tile profiles on the older Spanish-style homes scattered through the neighborhood. Our parts approach is simple: match to the existing line and color wherever the field is sound. We use CertainTeed Flintlastic on low-slope work instead of forcing a shingle below its minimum pitch. For partial repairs on Landmark and XT roofs, we match the existing shingle so the repair preserves the roof’s appearance and whatever manufacturer warranty the owner still holds. CertainTeed sales & service across Van Nuys means we keep the common profiles and accessory parts on hand so we’re not waiting on a distributor for a standard ridge cap or eave detail.

AfterCertainTeed Service Pricing in Van Nuys
CertainTeed roof repair in Van Nuys typically runs $325 to $680 for shingle replacement, depending on how many courses are involved and whether we’re re-setting the underlayment. Flat roof patches on Flintlastic sections usually fall between $450 and $950, with the higher end covering seam repairs that need re-torching across a larger area. Flashing repair around chimneys and scuppers generally lands between $280 and $600. A full replacement is a different conversation entirely, and we’ll walk you through the square-footage math, the deck condition, and the ventilation before we ever put a number on it. Heat-baked roofs with failed felt underneath cost more to fix properly, and we’ll tell you why in plain language. Call (844) 966-3891 for a line-item written estimate, free, no obligation.

FAQs – CertainTeed Roofing in Van Nuys
In Van Nuys, the seal strips on heat-aged Landmark or XT shingles often let go long before the tabs look bad from the ground. Rain driven by a Santa Ana wind gets under the lifted tabs and finds the nail line or the baked-out felt beneath. The roof looks fine from the curb because the damage is at the laps, not the surface. We find these leaks by testing the field, not just eyeballing it. Call (844) 966-3891 and we’ll trace it for you.
Sometimes, but on Van Nuys homes with original single-layer roofs from the 1950s or 60s, the felt underneath is usually baked to dust. Nailing new shingles over failed felt buys a few seasons at most, and it traps the heat problem that killed the first roof. We’ll inspect the deck and felt, then tell you straight whether a re-shingle makes sense or whether a tear-off and re-deck is the honest answer.
Not usually a product defect. In Van Nuys, Flintlastic seams pull apart most often where attic ventilation is undersized and heat builds under the membrane, especially on the shallow-pitch rear additions common to 1950s tract homes. The seam is the symptom. We fix the lap and address the ventilation so the next seam doesn’t open the same way.
Because the shingles and caps on your roof were already heat-baked brittle before the wind arrived. Van Nuys summers exceed 100°F routinely, and that oxidizes the asphalt and weakens the adhesive. When a Santa Ana gust hits a roof west of the 405, the caps and lifted tabs can’t re-seal. We replace the caps, re-set the windward shingles, and re-detail the rake edges so the wind has less to grab next time.
Yes. Van Nuys has a lot of low-rise apartment buildings with CertainTeed shingle fields on the pitched front sections and Flintlastic membranes on the flat rear sections. We repair both, and we’re comfortable working with property owners and managers on scupper repairs, membrane laps, and wind-damaged shingle courses. Call (844) 966-3891 to schedule a roof inspection.
