CertainTeed Roofing in La Crescenta-Montrose, CA | Orange County Roofing Co
We provide independent CertainTeed roofing service across La Crescenta-Montrose, from repairs on older Landmark installations to full tear-offs and Class A re-roofs. What makes our work here different is simple: we know how CertainTeed systems actually perform in the Crescenta Valley wind funnel and the foothill fire corridor above Foothill Boulevard. That local knowledge changes what we recommend. Call (866) 942-4187 for a free estimate on any CertainTeed roof.
Why La Crescenta-Montrose Residents Choose Us for CertainTeed Service
CertainTeed makes a lot of different roofing products, and the right one for a 1950s ranch on a terraced foothill lot isn’t necessarily the right one for a post-1960s addition lower on the slope. We work with CertainTeed’s full residential lineup, so we’re not stuck pushing one product on every house. Kurt Hensley, our owner, grew up watching crews work tile roofs on hillside homes in Orange, and that’s the lens he brings to La Crescenta-Montrose: read the roof, read the slope, read the brush exposure, then recommend. We’re an independent CertainTeed roofing contractor. We are not authorized, sponsored, or warranty-endorsed by CertainTeed, and that independence matters when the honest answer is that only a partial slope repair makes sense this year.
We inspect, repair, and replace roofs. One call covers a loose ridge cap, a full tear-off, or an evaluation after a Santa Ana event. If you’re not sure whether your roof needs work at all, our inspection service stands on its own. Our inspection tells you exactly what your roof needs, nothing more. From a single damaged shingle to a full tear-off and replacement, one call covers it. GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral: we install them all, so we can recommend honestly.

Common CertainTeed Roofing Problems We Solve in La Crescenta-Montrose
- Ridge caps and starter strips lifting on the windward slope. Santa Ana events accelerate through the Crescenta Valley and funnel along the Verdugo foothill slopes. We regularly see CertainTeed ridge caps peeled back on north- and east-facing ridges while the field shingles stay put. The fix is mechanical fastening and proper starter detailing, not just more sealant.
- Brittle, granule-starved shingles on south- and west-facing planes. Warm summers and concentrated winter rain mean sealant strips bake for months, then get hit with water. On CertainTeed installations that are 15-plus years old, we see granule loss and cracked tabs on the sun side long before the shaded slopes show wear. A partial slope replacement can buy years if the underlayment is still sound.
- Felt and flashing failures under original tile or shake on rear rooflines. Homes backing up to open Verdugo brush often have originalCertainTeed concrete tile or wood shake assemblies where the underlayment was never built for ember exposure. The ceiling stain shows up long after the flashing failed.
- Dry-rotted or split sheathing revealed at tear-off. Mid-century La Crescenta-Montrose homes frequently have wood shake laid over skip sheathing, or lower-slope composition on mixed-pitch framing. We’ve opened up roofs where the decking under an old CertainTeed system was splitting at the seams. That’s not a repair conversation; that’s a decking replacement conversation.
- Flat or low-slope section leaks on ranch additions. Post-1960s additions often have flat sections that were roofed with whatever was on hand. We service CertainTeed Flintlastic low-slope membrane systems when the addition leaks and the main roof is fine, so you’re not paying for a full re-roof over a 200-square-foot problem.
CertainTeed Service in La Crescenta-Montrose: What Local Conditions Mean for Your Equipment
La Crescenta-Montrose sits at the base of the Verdugo Mountains, inside the San Gabriel Mountains foothill fire corridor. That’s not a zoning footnote; it’s the single most important factor in how we spec a CertainTeed roof here. A re-roof on a home where the rear roofline faces open brush is judged on Class A assembly and ember-resistant vents, not just shingle warranty. Wood-shake replacement on those slopes often triggers brush-clearance requirements that a homeowner in a valley-floor neighborhood would never encounter. We’ve torn off original shake roofs on mid-century ranches off Foothill Boulevard where the rear slope had been flagged for brush clearance, and the real work was re-decking split skip sheathing and adding ember-resistant detailing before the first shingle went down. That’s the difference between a roof that looks good from the street and one that actually passes inspection and holds against the wind funnel. CertainTeed Landmark architectural shingles, properly installed with Class A assembly details, are a solid fit for those rear slopes. But the assembly matters more than the shingle.
CertainTeed Models & Products We Service in La Crescenta-Montrose
We work on CertainTeed Landmark architectural shingles, Presidential Shake and Presidential TL, XT 25 and other 3-tab shingles found on older ranch re-roofs, concrete tile and tile underlayment systems, and Flintlastic low-slope membrane on flat additions. When a repair calls for matching components, we use CertainTeed accessory products: ridge cap, starter, underlayment. Where the OEM detail is the weak point on a foothill roof, we use quality aftermarket flashing and ember-resistant vents instead, and we’ll tell you why. The right material for your roof, backed by the manufacturer’s own warranty, not whatever we happen to stock deepest. We carry seven major brands so you choose the roof that fits your home and budget, not ours.

FAQs – CertainTeed Roofing in La Crescenta-Montrose
Yes. La Crescenta-Montrose sits inside the San Gabriel Mountains foothill fire corridor, and many homes on slopes backing the Verdugos fall under local fire-safety requirements that mandate Class A assemblies and ember-resistant vents. We spec La Cañada Flintridge CertainTeed service with Landmark and Presidential systems accordingly. Call (866) 942-4187 to have us check your roof’s current assembly.
Santa Ana events funnel through the Crescenta Valley and concentrate wind uplift along the foothill slopes, and ridge caps on the windward side get hit hardest. The original install was often done with sealant only, and after enough dry heat the sealant fails. We refasten with mechanical attachments and proper starter detailing for CertainTeed repair in Sunland and nearby foothill areas. Call (866) 942-4187 for a repair quote.
The tile itself is probably not the problem. Underlayment and flashing under CertainTeed concrete tile degrade long before the tile shows wear, so CertainTeed repair in Burbank and Crescenta Valley homes follows the same pattern: especially on rear slopes facing open brush where the original assembly predates ember-resistant standards. We inspect underneath the tile and replace only what’s failing. Call (866) 942-4187 to schedule an inspection.
In most La Crescenta-Montrose cases, no. Shake roofs here are often laid over skip sheathing, and the brush-clearance and fire-rating requirements on foothill slopes mean the whole assembly needs to be re-decked and brought up to current Class A standards. Overlaying hides the problem and usually fails inspection. We’ll tell you straight what your roof actually needs. Call (866) 942-4187 for a free estimate.
Yes. Many La Crescenta-Montrose ranch homes have flat additions or carport sections with low-slope roofs. We service CertainTeed in Tujunga with Flintlastic membrane systems on those areas, so a leak over the patio doesn’t force you to re-roof the entire house. Call (866) 942-4187 to schedule a low-slope roof inspection.
