CertainTeed Roofing in Monrovia, CA | Suncrest Roof Repair
We provide independent CertainTeed roofing service across Monrovia, from leak diagnostics on Landmark shingles to full Presidio metal replacements. What makes our CertainTeed work different here is how we account for the foothill wind patterns and older housing stock that define Monrovia roofs. Call (866) 538-0713 for a free inspection and a straight answer about what your roof actually needs.
We know CertainTeed’s product line the way a mechanic knows a specific engine family: Landmark architectural shingles, Presidio metal, Hatteras, Symphony Slate. We’ve installed, repaired, and replaced all of them on homes throughout Monrovia’s 91016 and 91017 ZIP codes. If you’re researching whether to repair or replace a CertainTeed roof that’s aging in this specific climate, or you need Arcadia CertainTeed service, you’ve landed in the right place.
Why Monrovia Residents Choose Us for CertainTeed Service
Most roofing crews in the San Gabriel Valley work with one or two shingle brands, but we also bring Mayflower Village CertainTeed service experience to the table. We work with seven: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That matters when you own a CertainTeed roof because we’re not trying to sell you a switch to whatever’s in the warehouse. We’re recommending what fits your home and your budget. If CertainTeed Landmark has served your Monrovia house well for twenty years, we can keep it in the CertainTeed family. If Presidio metal makes more sense for your exposure, we’ll tell you that too.
Roland Cifuentes, our owner, grew up helping his uncle patch roofs along Foothill Boulevard in Rancho Cucamonga, and he’s been diagnosing roofing problems for going on two decades. He’s the kind of contractor who will tell you when a repair buys you five more years and when a replacement is the honest call. That’s the repair-first philosophy we bring to every CertainTeed inspection in Monrovia.

Common CertainTeed Roofing Problems We Solve in Monrovia
- Wind-lifted Landmark shingles along ridges and edges. Monrovia’s Santa Ana winds hit roofs on the north side of town hardest, and Landmark shingles on exposed ridge lines are the first to lift and crease. Once a shingle seal breaks, wind gets underneath and the problem spreads fast.
- Presidio metal fastener back-out and sealant failure. Monrovia’s hot, dry summers create serious thermal cycling on metal panels. Fasteners slowly work loose, and the sealant around roof penetrations degrades. We see this leak pattern most often on south-facing Presidio roofs with full sun exposure.
- Hatteras shingle granule loss on unshaded slopes. The intense UV that Monrovia’s foothill elevation brings accelerates granule shedding and cracking on older Hatteras installations. Once granules go, the asphalt layer is exposed and the clock starts ticking.
- Symphony Slate chipping and impact damage. Winter atmospheric rivers bring debris down from the San Gabriels, and homes with mature tree canopy, like those near Canyon Park, see cracked and chipped slate tiles after big storms.
- Critter damage to vents and fascia. Raccoons and squirrels are a real problem in Monrovia’s foothill neighborhoods. They chew through vent boots, nest in attics, and tear up fascia boards, which then lets water in around the roofline.
CertainTeed Service in Monrovia: What Local Conditions Mean for Your Equipment
Here’s the specific Monrovia factor most outside roofers miss: many original CertainTeed installations on homes built before the 1970s sit over skip sheathing, which is gapped wood boards rather than a solid deck. Current code requires a solid deck before any re-roof, which means a tear-off on an older Monrovia bungalow is a bigger scope than a tear-off on a 1990s tract home in a flatland city. If your home is off Foothill Boulevard or tucked into the tree-lined streets near Myrtle Avenue, there’s a real chance your CertainTeed shingles are sitting on skip sheathing right now. That changes the price, the timeline, and the materials list. We inspect for it before we quote, and we explain exactly what we find before we touch a thing.
On a 1920s bungalow near Canyon Park, we found original CertainTeed Landmark shingles lifting along the ridge after a Santa Ana wind event, and raccoons had chewed through two vent boots. We replaced the damaged shingles, upgraded the flashing and vent boots, and added a ridge vent to improve attic ventilation, solving both the wind damage and the critter entry in one pass. That’s the kind of combined problem Monrovia throws at a roof, and it’s why generic advice doesn’t hold up here.
CertainTeed Models & Products We Service in Monrovia
We install, repair, and replace the full CertainTeed residential line that’s common on Monrovia homes: Landmark Architectural Shingles, Presidio Metal Roofing, Hatteras Shingles, and Symphony Slate. For replacements and new installations, we use CertainTeed OEM shingles, underlayments, and accessories so your material warranty stays intact. For Presidio metal repairs where OEM panel availability is slow or overpriced, we source quality aftermarket panels and fasteners that match the profile. We stock the most common CertainTeed repair materials locally, which means faster turnarounds around Monrovia, though we never promise a timeline before we’ve seen the roof.
Our CertainTeed sales & service experience covers everything from single shingle swaps to full tear-offs with manufacturer-spec underlayment.

AfterCertainTeed Service Pricing in Monrovia
What you’ll pay for Duarte CertainTeed service or Monrovia work depends on a few things: whether we’re repairing a few shingles or replacing an entire slope, whether your home has skip sheathing, and which product line you have. Minor repairs, like replacing a handful of lifted Landmark shingles or resealing a Presidio penetration, typically run a few hundred dollars. Full roof replacements with CertainTeed materials range from roughly $12,000 to $35,000 depending on size, pitch, and decking work. A skip-sheathing upgrade over the whole roof adds real scope, which we explain in writing before any work begins.
One thing we can commit to: you’ll get a line-item quote, not a round number pulled from the air. Call (866) 538-0713 to schedule a free inspection and we’ll walk you through what your roof needs, what it costs, and what can wait.

FAQs – CertainTeed Roofing in Monrovia
Yes, we repair wind-lifted Landmark shingles regularly in Monrovia. We remove the damaged shingles, check the seal strips on surrounding rows, and replace what’s compromised with matching CertainTeed Landmark shingles. If the lift is isolated to a ridge line or an exposed edge, a repair is usually the right call. If wind damage is widespread, we’ll tell you honestly and quote a partial or full replacement instead. Call (866) 538-0713 for an exact assessment, the estimate’s free.
Skip sheathing is a roof deck made of spaced wood boards rather than a solid plywood or OSB surface. Many pre-1970s Monrovia homes, especially Craftsman bungalows and mid-century builds, have it under their original CertainTeed shingles. Current code requires a solid deck before re-roofing, so if you have skip sheathing, a full replacement includes sheathing the entire roof. We can identify it during inspection, usually by checking the attic or a shingle edge. Call (866) 538-0713 and we’ll take a look.
Monrovia sits at the base of the San Gabriel Mountains, which means hotter afternoon exposure on south-facing and west-facing slopes than flatland cities like El Monte or Baldwin Park or even CertainTeed in Bradbury see. That heat accelerates granule loss and UV cracking on CertainTeed asphalt shingles, especially Hatteras on unshaded slopes. Thermal cycling between hot days and cooler mountain nights also stresses the adhesive seals on Landmark shingles. It’s not dramatic in any single year, but over a decade it’s measurable.
Yes, Presidio metal roofing handles Monrovia’s heat and Santa Ana winds well, which is why we recommend it for many foothill homes. The main issue we see is fastener back-out and sealant degradation at penetrations over time, which is more about maintenance than the product failing. Metal reflects heat better than asphalt, so it often extends roof life in hot climates like Monrovia’s. Plan on re-sealing penetrations every seven to ten years. Call (866) 538-0713 if you want us to inspect your Presidio roof before the next rainy season.
No, and you shouldn’t let anyone do that on your Monrovia home. Building code requires a solid, properly fastened deck before new CertainTeed shingles go on, and installing over skip sheathing will fail inspection and void your material warranty. We include deck replacement in any quote where skip sheathing is present, and we explain the added scope before we start. Call (866) 538-0713 for a quote that covers the deck work, not one that hides it until mid-project.
