CertainTeed Roofing in Sunland, CA | Gable Roof Repair
We provide independent CertainTeed roofing service across Sunland, CA, from shingle replacement to full re-roofs on Landmark, Presidential, and older three-tab systems. What sets our CertainTeed work apart here: we understand how these shingles actually behave in Sunland’s Very High Fire Hazard Severity Zone, where Santa Ana gusts and ember exposure punish roofs in ways valley-floor cities never see. Call (866) 650-8319 for a free estimate.
We’re the crew Sunland homeowners call when a CertainTeed roof starts showing its age or takes wind damage. Our relationship with CertainTeed is straightforward: we install, repair, and inspect their products as an independent contractor, not as a manufacturer affiliate. That means our recommendations are based on what the roof needs, not what a brand program tells us to push. For a deeper look at our CertainTeed sales & service approach across Southern California, we’ve outlined how we work with this product line.
Why Sunland Residents Choose Us for CertainTeed Service
Most of Sunland’s housing stock is mid-century ranch and Spanish-style stucco, built between the 1940s and 1970s. Many of those original roofs are long gone, but plenty still carry second-generation CertainTeed shingles that are now 15 to 25 years old. We know exactly how those roofs were put together, and what fails first when the wind and sun get after them.
Neil Drummond, our owner, has spent the better part of three decades diagnosing roof failures across Southern California. He learned roofing fundamentals at Saddleback College’s construction technology program and has worked roofs from the coast to the foothills ever since. The roof doesn’t lie, the materials tell you exactly what went wrong and when. That’s the standard we bring to every CertainTeed inspection and repair in Sunland.
We use CertainTeed-branded shingles when matching the existing roof makes sense, and quality matching underlayments, ridge products, and flashing otherwise. The shingle field is rarely the whole story on a Sunland roof. For the broader picture of where we work, see our Sunland service area page.

Common CertainTeed Roofing Problems We Solve in Sunland
- Wind-scoured ridge caps and lifted shingle tabs. Santa Ana gusts funnel through the Crescenta Valley corridor and hit west- and north-facing roof planes hard. On CertainTeed Landmark and three-tab roofs, the seal strips shear free rather than the shingle wearing out. We see this on nearly every hillside street after a serious wind event.
- Sun-baked, brittle seal strips on south-facing slopes. Sunland runs hot and dry with intense summer UV. After 15-plus years, the adhesive strip on CertainTeed shingles can turn brittle and release, so the first strong offshore wind peels whole courses off the deck.
- Failed underlayment on low-slope addition sections and detached garages. Many Sunland homes have flat or low-slope sections over additions and detached garages, where CertainTeed shingles were laid over minimal or aged felt. Leaks show up at the flat-to-pitched transition, not in the open field where you’d expect them.
- Ember- and wind-vulnerable detailing at vents, valleys, and eave edges. Sunland sits in a Very High Fire Hazard Severity Zone. Older CertainTeed installs often have open vents and detailing that doesn’t meet Class A assembly expectations, letting embers and driven rain past otherwise sound shingles.
- Hail and debris impact on aging three-tab roofs. The older XT 25 and XT 30 shingles still on Sunland’s tract and garage roofs have thinner mats than modern architectural shingles. Once the granule surface is compromised by UV, even minor impact can crack tabs and expose the mat.
CertainTeed Service in Sunland: What Local Conditions Mean for Your Roof
Sunland’s hillside streets climbing toward the Verdugos sit inside a Very High Fire Hazard Severity Zone. That’s a legal designation, not a marketing phrase. It means a CertainTeed shingle re-roof here isn’t just about wind rating or curb appeal. Inspectors want to see a Class A assembly with ember-resistant vents and edge detailing, a standard that Sunland roofs carry but valley-floor homes in CertainTeed in Burbank and Glendale generally don’t. This changes the conversation on every re-roof we quote in 91040 and 91041. Underlayment choice, vent selection, valley metal, eave edge detailing: each decision has to answer to the fire code before it answers to aesthetics. A roof that passes in Burbank may not pass in Sunland, and we’ve seen homeowners get burned on that difference more than once.
Here’s a field example. After a fall Santa Ana event, our crew was called out to a 1950s ranch on a side street off Foothill Blvd in 91040 where a north-facing Landmark slope had shed a run of ridge caps and several tabs at the gable edge. When we pulled the damaged shingles, the original felt underneath was dried and torn. We replaced the ridge and field shingles with matching CertainTeed Landmark, upgraded the underlayment at the exposed section, and re-fastened the edge metal with a wind-rated nailing pattern. We also swapped the old open vent for an ember-resistant vent to bring that section closer to Class A detailing. That’s the difference between a patch job and an actual fix for a Sunland roof.
CertainTeed Models & Products We Service in Sunland
We work on the full CertainTeed residential lineup common across Sunland:
- CertainTeed Landmark and Landmark Pro architectural shingles. The most common shingle on Sunland re-roofs from the last 15 to 20 years. We stock matching Landmark colors for fast plane-by-plane repairs.
- CertainTeed Presidential Shake and Presidential TL luxury shingles. Found on higher-end Sunland hillside homes. These are thicker, heavier units that need specific fastening patterns for wind uplift resistance.
- CertainTeed XT 25 and XT 30 three-tab shingles. The original or second-generation roof on many 1950s and 1960s Sunland tract homes and detached garages. We keep a limited stock of matching colors for spot repairs.
- CertainTeed DiamondDeck and RoofRunner synthetic underlayments. Used under tile and shingle assemblies. We specify these on Sunland re-roofs where fire rating and UV exposure demand a synthetic over felt.
We use CertainTeed-branded shingles when matching the existing roof matters, and quality matching underlayments, ridge products, and flashing otherwise. We’re not tied to one brand’s system for every component, because a Sunland roof with CertainTeed shingles may still need a different underlayment or vent spec to meet local fire code.

AfterCertainTeed Service Pricing in Sunland
CertainTeed roof repair and replacement costs in Sunland depend on the roof’s condition, access, and what the fire code requires. Here’s what homeowners in 91040 and 91041 can expect as of 2026:
- Shingle replacement (spot repair, 1 to 10 shingles): $280 to $550 per repair, depending on roof pitch, access, and shingle type
- Slope repair (wind-damaged section, 50 to 200 sq ft): $850 to $2,400, including underlayment repair and re-fastening edge metal
- Full re-roof with CertainTeed Landmark architectural shingles: $8,500 to $16,500 for a typical 1,200 to 2,000 sq ft Sunland ranch, including tear-off, underlayment, and Class A detailing
- Roof inspection with written findings: $150 to $350, credited toward any repair or replacement we do
What drives the cost in Sunland specifically is the fire-zone detailing: ember-resistant vents, Class A-compatible edge metal, and synthetic underlayment add $1,200 to $2,800 to a re-roof over a standard valley-floor job. We quote that work up front. Call (866) 650-8319 for a free, written line-item estimate, no change orders down the line.

FAQs – CertainTeed Roofing in Sunland
Lifted shingles have intact seal strips and can often be re-sealed or re-fastened. Failed shingles have torn seal strips, cracked tabs, or exposed fasteners, which means they’ll keep lifting every time the wind blows. We inspect the slope and tell you which situation you have before recommending any work. Call (866) 650-8319 to schedule a post-wind inspection.
If your home is inside Sunland’s Very High Fire Hazard Severity Zone, which covers most hillside streets climbing toward the Verdugos, then yes. Inspectors will want to see Class A-compatible shingles, ember-resistant vents, and proper edge detailing on any re-roof. Repair work on existing slopes can proceed without a full assembly upgrade, but new replacement sections should move toward code compliance.
CertainTeed shingles are rated for slopes of 2:12 and above. Sections below that threshold need a low-slope system, and the transition between flat and pitched is where we see the most leaks on Sunland homes. We’ll assess each section separately and spec the right product for each plane rather than forcing shingles everywhere. Call (866) 650-8319 for a free assessment of your roof’s flat-to-pitched transitions.
If the underlayment is intact and the shingles have useful life left, a plane-by-plane repair holds up fine. If the underlayment is dried, torn, or the shingles are near the end of their service life, replacing one slope just delays the full job by a year or two while costs rise. We’ll show you the condition under the shingles before you decide.
We specify synthetic underlayment like CertainTeed DiamondDeck on Sunland re-roofs because it holds up to UV exposure during install and provides a better nail-seal than felt, which matters in high-wind corridors. In fire-hazard zones, synthetic is also the preferred base for Class A assemblies. The added material cost is modest next to the protection it buys. Call (866) 650-8319 for a quote on your specific roof.
