CertainTeed Roofing in Sunland, CA | Crown Line Roof Repair
We provide independent CertainTeed roofing service across Sunland, CA. If your CertainTeed roof has lost shingle tabs after a Santa Ana wind event, or your concrete tile looks fine but the ceiling stains say otherwise, we diagnose it and fix what’s actually failing. Our CertainTeed work here is built around one thing: Sunland’s wind and fire zone demand a different assembly than flatland roofs a few miles south. Call (844) 966-3891 for a straight answer.
Why Sunland Residents Choose Us for CertainTeed Service
We work on CertainTeed roofs across the Verdugo foothills every season, so we know how Landmark architectural shingles, Presidio/XT concrete tile, and Flintlastic low-slope membranes actually behave under Sunland’s Santa Ana gusts and inland heat. As an independent contractor we install and repair CertainTeed systems on their merits. No dealer agreement, no manufacturer authorization. Just a crew that’s torn into these assemblies enough times to know exactly where they fail first.
Noel Carrasco, our owner, grew up a few blocks from the Euclid Street corridor in Garden Grove and has been reading Southern California rooflines for most of his life. He picked up the fundamentals through the construction technology program at Santiago Canyon College in Orange, then spent years working every roof type this region throws at you: flat torch-down membranes, clay tile on older Spanish-style homes, and the full range of asphalt shingles from three-tab up through impact-resistant architectural grades. He runs our CertainTeed sales & service work the same way he’d assess any roof: by what the material and the site are telling us, not by what’s easiest to sell.
When a Sunland homeowner calls us about a CertainTeed roof, they get a repair-first assessment. If a flashing or vent boot has failed, we fix that and leave good shingles alone. If the deck or underlayment is the real failure, we say so and scope the tear-off. The roof tells you what it needs. You just have to know how to read it.

Common CertainTeed Roofing Problems We Solve in Sunland
These are the failure patterns we see most on CertainTeed roofs in this part of the Verdugo foothills. Each one ties directly to what Sunland throws at a roof.
- Wind-uplift and seal-strip failure on Landmark shingle fields and ridge caps. After a Santa Ana push through the canyons, tabs lift on the windward slope before they ever leak. We find it most often on the rake and ridge edges where wind pressure concentrates. The fix is resealing or replacing the affected courses with matching CertainTeed shingles, not just nailing down what’s loose.
- Baked-out underlayment beneath concrete tile on low-pitch ranchers. Many 1950s and 1960s tract homes in Sunland have original tile that still looks fine from the street, but the felt underneath has dried to dust after decades of inland heat. The first winter storm with wind-driven rain finds the ceiling. Tile looks intact; the CertainTeed underlayment is gone. This is a tile underlayment replacement, not a tile replacement.
- Flashing and vent-boot fatigue at penetrations and chimneys. Thermal cycling in Sunland’s hot summers loosens seals around pipes, vents, and chimneys. Ember exposure in the high fire severity zone accelerates it. On a CertainTeed roof, the first leak point is often the flashing, not the field. We replace the boots and reseal the flashing before the shingle field gives out.
- Lifted or cracked tile and popped fasteners at hip and ridge lines on hillside custom homes. Steep hillside rooflines concentrate wind pressure at the edges, and the pressure changes across a single plane. CertainTeed Presidio and XT tile handles it well when it’s fastened correctly. When original fasteners pop, we reset the tile with proper clips and match the profile.
- Skip-sheathing discovered under original roofs. A lot of older Sunland homes still have original skip sheathing under the shingles or tile. It was fine in 1965. It doesn’t meet current code, and a re-roof won’t pass inspection until it’s addressed. We re-deck to solid plywood before laying new CertainTeed material.
CertainTeed Service in Sunland: What Local Conditions Mean for Your Roof
Sunland sits in a high fire severity zone, and that changes what a certain CertainTeed assembly should look like here. A Class A fire-rated shingle field, ember-resistant vents, and closed eave and ridge detail are a different spec than a flatland CertainTeed re-roof a few miles south. That’s the reason a wind-damage repair on a Sunland roof often becomes a fire-hardening upgrade. The two stressors aren’t separate. Santa Ana winds carry embers, and the same gust that peels a ridge cap also drives a burning branch into your eave.
After a hard Santa Ana push through the canyons, we were called to a 1960s rancher off Sunland Blvd where the windward slope had lost shingle tabs at the rake and a couple of ridge caps were peeled back. Pulling the course exposed the original skip sheathing the homeowner didn’t know was there. We re-decked to solid plywood, set a new Class A fire-rated CertainTeed Landmark field with properly sealed caps, and resealed the chimney flashing before the next storm. The result is a roof that meets WUI fire expectations for the hills, not just a patched slope. That’s the Sunland difference, and it’s not something a generic roofer from down the hill is going to catch.
CertainTeed Models & Products We Service in Sunland
We service the full CertainTeed residential range across our Sunland service area, including Landmark architectural shingles, XT and Presidio concrete tile, Flintlastic SA low-slope membrane for flat patio sections, and Cedar Impressions or Symphony profiles where historical looks are involved. On repairs, we match the CertainTeed system that’s already on the roof: same shingle line, tile profile, or Flintlastic membrane. We use OEM or regionally matched components rather than mixing incompatible layers. For flat and low-slope sections on Sunland’s ranchers, we keep Flintlastic materials in our regular supply set so we’re not waiting on a distributor order to start a repair.

AfterCertainTeed Service Pricing in Sunland
Here’s what to expect when you’re pricing CertainTeed roof work in Sunland.
- Roof inspection: $150 – $350 as a standalone service, credited toward any repair or replacement we do after that inspection.
- Minor CertainTeed repair (flashing, vent boots, small shingle replacement): $250 – $800 depending on access and extent.
- Tile underlayment replacement: $4,500 – $9,000 for a typical 1,500 – 2,500 sq ft Sunland rancher, depending on pitch, tile removal complexity, and deck condition.
- Full CertainTeed re-roof: $11,000 – $26,000 depending on roof size, pitch, tear-off layers, and whether skip sheathing replacement is required.
- Skip sheathing re-deck: $2 – $4 per sq ft of affected area added to the project scope.
What drives cost here more than anything is what’s under the surface. An original 1960s roof with skip sheathing and baked-out underlayment is a different job than a 2005 architectural shingle roof with a failed flashing. Our (844) 966-3891 estimates are free and written line-by-line, so you see exactly what’s included and what is not a problem worth touching. Call us for an exact quote on your CertainTeed roof.

FAQs – CertainTeed Roofing in Sunland
Canyon-funneled wind hits the windward slope harder than the leeward side, and the seal strips on older CertainTeed Landmark shingles lose their grip after enough thermal cycling. The tabs lift at the rake and ridge first, which is where wind pressure concentrates. What you’re seeing isn’t random. It’s a wind-uplift failure pattern that’s specific to your roof’s orientation in the Verdugo foothills. The fix is resealing or replacing the affected courses with matching CertainTeed shingles. Call (844) 966-3891 if you want us to look at the windward slope before the next Santa Ana event.
If the tile looks fine, the leak is almost always the underlayment underneath it. On Sunland’s low-pitch 1950s – 70s ranchers, decades of inland heat bake the felt under concrete tile until it dries to dust. The tile still sheds water, but any wind-driven rain that gets under it goes straight to your decking and ceiling. We scope a tile underlayment replacement: lift the intact tile, remove the failed felt, install a new high-temp synthetic or SA membrane, and reset the same tile. Call (844) 966-3891 for an assessment of what’s actually under your tile.
Yes. Sunland’s fire zone means the assembly matters as much as the shingle itself. A proper CertainTeed re-roof here includes Class A fire-rated shingles, ember-resistant vents, and closed eave and ridge detail. If your chase is old skip sheathing, that gets re-decked so embers can’t collect in the gaps. The shingle is one layer of a fire-hardening system, not the whole system.
No, skip sheathing won’t pass inspection under a new CertainTeed roof in Sunland, and it’s not something you want under any fire-rated assembly. We remove it and re-deck to solid plywood. The cost is $2 – $4 per sq ft of affected area, and it’s a line item you’ll see on the estimate, not a surprise change order. Most older Sunland homes need this once we open the roof up.
We repair what’s repairable and replace what isn’t. If the flashing around a chimney or vent has failed, we reseal or replace it and leave the good shingles alone. If the decking underneath is rotted or was skip-sheathed, we scope that section for replacement. The numbers on the estimate tell you what’s fair. Call (844) 966-3891 to get a line-by-line quote.
