CertainTeed Roofing in Citrus, CA | Millstone Roofing
We provide independent CertainTeed roofing service across Citrus, CA, from targeted shingle repair to full replacement of Landmark, Presidential Shake, and Flintlastic systems. What makes our CertainTeed work different here is straightforward: Citrus’s 100°F+ summers and Santa Ana winds expose specific failure points in these products that coastal roofers rarely see, and we’ve spent years learning exactly where those failures show up first. Call (855) 341-6021 for a free estimate. We inspect first, then recommend what the roof actually needs.
Why Citrus Residents Choose Us for CertainTeed Service
We’ve been installing and repairing CertainTeed roofing systems across the San Gabriel Valley for over two decades, and we know exactly how their shingle and low-slope lines behave under Citrus’s extreme thermal cycling. Our crew is independent and factory-trained on CertainTeed products. We’re not a manufacturer rep pushing one product line. We carry the specialized underlayments and fasteners their systems require, and we keep common CertainTeed accessories in local stock so repairs don’t stall waiting on parts. For broader CertainTeed sales & service, our team handles everything from single-shake replacement to complete tear-offs.
Nelson Ibarra, our owner, grew up in the Pomona Valley and spent two decades working roofs across the Inland Valley before starting Millstone. He’s known for honest material recommendations. If a repair will hold, he’ll say so before he ever mentions a replacement. That’s the approach we take on every CertainTeed roof in Citrus.

Common CertainTeed Roofing Problems We Solve in Citrus
- Landmark granule loss on east-facing slopes. Repeated 100°F+ summers bake the asphalt layer, then Santa Ana winds abrade the loosened granules. East-facing slopes get the worst of it because they catch the morning sun and the wind. We often find bare patches on shingles that are only 10-12 years old in Citrus, not the 20+ years the product should deliver.
- Presidential Shake thermal cracking at the sealant strip. The thicker profile looks great but holds more heat. When temperatures swing from 105°F days to cooler nights, the sealant strip expands and contracts. Cracks form. The first strong Santa Ana event after a dry summer lifts those cracked tabs and peels them back. We see this pattern every October and November in Citrus.
- Split and cracked wood-shake on older homes. Citrus has a lot of 1950s-70s tract homes still carrying original CertainTeed wood-shake roofs. Those shakes were never designed for this heat. They split along the grain, especially on west-facing slopes with intense afternoon sun. By the time we’re called, fastener fatigue has usually set in too.
- Flintlastic SA membrane blisters and seam separation. Mid-century built-up roofs in Citrus trap attic heat when ventilation is poor. That heat pushes up from underneath, creating blisters in the cap sheet and stress at the seams. Once a seam opens, water gets in fast during the winter rains.
- Ventilation-related premature wear. Attic heat buildup accelerates every failure mode above. Many Citrus homes still have original passive vents that don’t move nearly enough air for a 105°F summer day. We address ventilation as part of any CertainTeed repair or replacement because it’s the difference between a roof that lasts 20 years and one that fails in 12.
CertainTeed Service in Citrus: What Local Conditions Mean for Your Equipment
Here’s the thing about Citrus that changes how we approach CertainTeed work: the city sits in a low spot in the San Gabriel Valley’s hot interior, where summer highs routinely exceed 100°F and the dry Santa Ana winds strip moisture from roofing materials faster than in foothill cities like Glendora or Azusa. But the bigger issue is the housing stock. Much of Citrus was built in the 1950s-70s, and many of those mid-century tract homes still carry their original wood-shake and low-slope built-up roofs. Those roofs were designed for a cooler California that no longer exists here. Thermal cycling from 40°F winter nights to 105°F summer days causes expansion and contraction that fatigues fasteners, cracks sealant strips, and accelerates granule loss. After a dry summer, the first strong Santa Ana wind event often peels back aged shingles and shakes on east-facing slopes, which is why roofers in Citrus get a rush of emergency calls in October and November, not just during the rainy season. For CertainTeed owners specifically, this means Landmark shingles in Citrus will show granule loss years earlier than the same product in a coastal city like Long Beach. It’s not a product defect. It’s the environment. We plan for it.
CertainTeed Models & Products We Service in Citrus
We work on the full CertainTeed roofing line that’s common in Citrus and the surrounding 91702 area. This includes Landmark architectural shingles, which are the most popular certainteed product on local tract homes, Presidential Shake TL and Solaris for thicker, high-profile looks, XtraWear and Horizon shingles for budget-conscious replacements, and Flintlastic SA capped sheet for low-slope and flat roof applications. We use CertainTeed OEM accessories like their Shadow Ridge vents and SwiftStart starter strips whenever they improve system performance, but we also trust quality aftermarket underlayments and fasteners that meet or exceed manufacturer specs. That mix keeps repairs cost-effective without cutting corners on the parts that matter.

FAQs – CertainTeed Roofing in Citrus
Yes, it’s unfortunately common here. Citrus’s 100°F+ summers soften the asphalt and loosen granule adhesion, and the Santa Ana winds finish the job by blasting those granules off the east and west-facing slopes. In coastal areas, 12 years of wear might be unusual. In Citrus, we see it regularly on Landmark roofs that haven’t had proper ventilation. The fix depends on how widespread the granule loss is. Isolated patches can be addressed, but if you’re seeing bare asphalt across a full slope, replacement is the honest recommendation. Call (855) 341-6021 for a free inspection and we’ll tell you which way to go.
It depends on the condition of the shakes themselves. Many Citrus homes still have original CertainTeed wood-shake from the 1960s. If the shakes are splitting along the grain and fasteners are pulling out, patching becomes a temporary fix that costs you more over time. Isolated damage from a storm or a fallen branch can be repaired with matching Presidential Shake materials. Widespread dry-rot and fastener fatigue across multiple slopes means replacement is the honest call. We’ll inspect and show you photos of what we find before we quote anything.
For most Citrus homes, we recommend Landmark architectural shingles in a lighter color with a high-reflectivity granule. They offer a good balance of heat resistance, wind rating, and cost. If you want stronger aesthetic presence on a ranch-style home, Presidential Shake TL works well, but the thicker profile holds more heat, so we pair it with upgraded ridge ventilation. The key isn’t just the shingle; it’s the ventilation design underneath. A quality CertainTeed shingle with poor attic airflow will still fail early in Citrus. Call (855) 341-6021 for product recommendations matched to your specific roof pitch and orientation.
If your flat or low-slope roof has a black granulated rolled membrane, it may be Flintlastic SA or a similar cap sheet. You can often identify it by checking for a manufacturer stamp on an exposed edge or by checking your original build documents. The better way is to have us look. Flintlastic can be patched for isolated blisters or seam separation, but if the membrane is 20+ years old and blistering across wide areas of a mid-century Citrus built-up roof, patching becomes a losing game. We’ll tell you which situation you have. Estimates are free.
Yes. October and November bring wind damage calls to Citrus every year, and we prioritize homes with active leaks or exposed decking. If your CertainTeed shingles or shakes have been peeled back by a Santa Ana event, call (855) 341-6021 and we’ll get out to tarp and secure the roof, then schedule the permanent repair. The quicker you call, the less water damage you’ll be dealing with.
