CertainTeed Roofing in Sunland, CA | Ridge Cap Roof Repair
We service and install CertainTeed roofing systems across Sunland’s foothill streets and flatland tracts, from full replacements to targeted ridge cap and flashing repairs. What makes our CertainTeed work different here is simple: Sunland sits where Big Tujunga Canyon opens into the Verdugo foothills, and that canyon mouth changes how shingles fail. Call (866) 361-0798 for a free estimate on your CertainTeed roof.
Why Sunland Residents Choose Us for CertainTeed Service
We’ve built our CertainTeed repair and replacement work around the specific way Sunland’s canyon-mouth exposure attacks shingles: wind-scoured ridges, UV-brittled field tabs, and flashing details that have to hold at the wildland-urban interface. We’re an independent CertainTeed service provider, not authorized or sponsored by CertainTeed, so our recommendations are based on what we find on the roof, not a dealer program.
Our team knows the CertainTeed product lines well because we work with seven manufacturers, not one. That’s not a sales pitch; it’s how we ended up noticing the failure patterns that repeat on Sunland roofs. CertainTeed Landmark architectural shingles, for example, hold up differently on a west-facing foothill slope than they do on CertainTeed in Burbank flatland roofs ten miles south. Noel Cardenas, our owner, learned roofing through the construction trades program at San Bernardino Valley College and spent over two decades working Inland Empire roofs before bringing that eye to Sunland’s hillside homes. He’ll look at a wind-lifted ridge cap and tell you what the rest of the roof is already saying.
Inspection, repair, and replacement all stay under our crew. No scope hand-offs to outside subs, no findings lost between a separate inspector and a separate installer. The same person who walks your roof writes the fix.

Common CertainTeed Roofing Problems We Solve in Sunland
- Santa Ana wind uplift on ridge caps and field tabs. West-facing slopes in Sunland catch the brunt of dry wind funneling through Big Tujunga wash. CertainTeed ridge caps peel loose and field tabs lift while the leeward plane on the same roof looks untouched. We re-secure with high-wind nailing patterns and replace caps that have lost their sealant bond.
- UV-brittled shingle mats on exposed slopes. Canyon-mouth summer sun in Sunland bakes roofs. Granules strip faster than on flatland roofs of the same age, and the shingle mat dries from the underside up. A CertainTeed roof that looks tired from the ground often has brittle mats underneath, which is why we inspect before we recommend replacement.
- Leaks at valleys and dormer flashings on steep-pitch homes. Sunland’s foothill streets climbing out of the canyon are full of multi-level homes with complex valleys and dormers. The first leak point is rarely the shingle field; it’s where a patio addition meets the main roof at a low slope, or where valley metal has worked loose over time.
- Missing ember-resistant venting and edge detail at the WUI edge. A Class A shingle alone doesn’t hold up a fire defense when embers get pulled through attic vents. Older Sunland assemblies often lack ember-resistant vents and proper edge metal. Even roof repairs here should address those details.
- Failed Flintlastic underlayment at valleys and eaves. CertainTeed Flintlastic is a solid self-adhered underlayment, but the dryness and heat cycles in Sunland age it. We’ve pulled back shingles to find brittle underlayment at valleys and eave edges where water had an easy path underneath.
CertainTeed Service in Sunland: What Local Conditions Mean for Your Roof
Sunland’s foothill streets climbing out of Big Tujunga Canyon put roofs in a degree of Santa Ana wind and ember exposure that CertainTeed repair in Tujunga and flatland Burbank and North Hollywood roofs never face. We routinely spec ember-resistant vents and Class A assemblies alongside shingle work on the same street where a downslope neighbor’s roof needs only UV-driven replacement. The geography does that. The canyon mouth channels wind, and the same dryness that desiccates shingles turns the surrounding hillsides into ember sources during fire season. A CertainTeed roof in Sunland isn’t just a shingle assembly; it’s a wind-secured, fire-rated defense system, and the detailing around the edges and penetrations carries as much weight as the shingle field itself. If the ridge cap is failing, the rest of the roof is already telling you something. You just have to know where to look.
On a steep-pitch hillside ranch up in the foothill streets near the canyon, a west-facing slope came back from a Santa Ana event with CertainTeed ridge caps scoured loose and field tabs lifted while the east slope was intact. We re-secured the ridge and edge metal with a high-wind nailing pattern, replaced brittle Flintlastic underlayment at the valley where it had gone weak, and fitted ember-resistant vents so the roof met the Class A assembly detailing the homeowner’s carrier wanted documented. Repair when it makes sense. Replace when it doesn’t.
CertainTeed Models & Products We Service in Sunland
Our crews handle the full CertainTeed roofing range: Landmark architectural shingles, Presidential Shake, XT25 three-tab, and Flintlastic self-adhered underlayment and accessories. For Sunland work, we keep CertainTeed-branded shingles, ridge caps, and underlayment stocked locally for fast turnaround, plus quality aftermarket flashing and vent components where they outperform at the detail level. We don’t make fake OEM claims. When a system match matters, we use CertainTeed-branded materials. When a detail needs better flashing than the original spec, we say so and install accordingly. From the ridge cap down, it’s all inspected and installed by CertainTeed sales & service work we stand behind.

FAQs – CertainTeed Roofing in Sunland
Ridge caps blow off because wind channeled through Big Tujunga Canyon hits west-facing slopes at full force and the caps lose their sealant bond. We re-secure them with a high-wind nailing pattern rather than relying on adhesive alone, and we replace any cap whose underside has lost its grip. Call (866) 361-0798 and we’ll walk your ridge line before the next wind event.
No. A Class A shingle is one layer of the fire defense, but embers get pulled through attic vents and under open edges. If your roof lacks ember-resistant venting and proper edge metal, the assembly doesn’t perform as Class A even if the shingle itself is rated for it. We inspect the whole assembly, not just the shingle field.
Get on the roof or have us inspect it. Wind uplift shows up as lifted tabs, loose ridge caps, and nail pops along rakes and eaves long before the roof looks damaged from the street. We document what we find in a written report you can send to your carrier.
Very common in Sunland. Steep-pitch foothill homes with patio additions have complex valleys and low-slope transitions, and those are the first places water finds a path. It’s usually a flashing or underlayment problem, not a shingle problem, and it’s often repairable without touching the shingle field. Call (866) 361-0798 for an inspection that pinpoints the entry point.
Look for granule loss in gutters, curling at the edges, and any shingle that feels brittle under hand pressure. But the real answer comes from the underside of the mat and the condition of the underlayment. We inspect those layers before we recommend anything. Repair when it makes sense. Replace when it doesn’t. Estimates are free.
