CertainTeed Roofing in Monrovia, CA | Tilecraft Roofing
We provide independent CertainTeed roofing service across Monrovia, from the 91016 flats up into the foothill streets north of Foothill Boulevard. That independence matters: we’re not tied to a manufacturer’s sales quota, so our inspections tell you what your CertainTeed roof actually needs, not what we need to sell. Call (833) 467-4846 for a free estimate from Ruben Castellano and the Tilecraft Roofing crew.
Why Monrovia Residents Choose Us for CertainTeed Service
We’ve torn off and re-roofed decades of CertainTeed Landmark and XT shingles across Monrovia’s foothill streets, so we know how their sealants, mat construction, and fire-rated assemblies actually age under San Gabriel sun and Santa Ana wind. For homeowners needing Roof Repair – Monrovia, we bring that same field knowledge to every call. Ruben Castellano grew up a few blocks from Hollydale Regional Park and has spent his entire working life within a few miles of where he was raised. He learned the trade at East Los Angeles College and spent years on residential and commercial roofs across the Southeast LA corridor before building Tilecraft Roofing. When a Landmark field fails in Monrovia, we know whether it’s a sealant issue, a decking problem, or just time. We look before we quote. That’s the whole approach.
We are an independent CertainTeed service provider, not authorized, sponsored, or warranty-backed by CertainTeed. What we bring is field experience with their product lines and the freedom to recommend repair when repair is right and replacement when it’s not. Seven leading brands, one crew, but this page is about CertainTeed because that’s what many Monrovia roofs are already wearing. We’ve also handled CertainTeed in Bradbury and neighboring foothill communities with the same independent approach.

Common CertainTeed Roofing Problems We Solve in Monrovia
- Wind-lifted Landmark shingles along ridge and rake edges. Santa Ana winds hit Monrovia hard in October and November. When Landmark shingles were installed in low temps or over-driven at the nail line, the sealant strips release and the shingles crease or lift. We see this most on the exposed south and east exposures in the 91016 flats.
- UV degradation and granule loss on XT 25 three-tab fields. The south and west facing slopes of Monrovia homes take intense summer sun. XT 25 three-tabs on original or second-layer roofs past 20 years lose granules fast here. Once the mat shows through, spot repair stops making sense; the field is done.
- Moss and dry rot on north-slope Landmark roofs. North of Foothill Blvd, north-slope roofs stay shaded and damp far longer than valley roofs. Moss gathers at valley and chimney flashing, and dry rot follows. A valley roofer would never check these spots; we do, because Monrovia’s foothill microclimate makes it a local necessity.
- Failed Flintlastic SA underlayment at WUI-critical eaves and valleys. Canyon-edge homes and parcels in the wildland-urban interface carry code and insurance demands for ember-resistant detailing. When Flintlastic SA underlayment wasn’t maintained, wind-driven rain finds the decking through the same gaps embers would use.
- Skip-sheathing and dry-rotted fascia under older roofs. Much of Monrovia’s housing stock dates from the 1900s to 1950s. Tear-offs on original Craftsman bungalows often reveal skip-sheathing, dry-rotted fascia, and decking that has to be quoted before new CertainTeed shingles go down.
CertainTeed Service in Monrovia: What Local Conditions Mean for Your Roof
Here’s what actually separates CertainTeed work in Monrovia from the same brand in Arcadia, Pasadena, or anywhere else: the same CertainTeed Landmark job can be two completely different scopes depending on which side of Foothill Blvd you live on. North of Foothill, in the foothill streets around North Myrtle Avenue and Canyon Crest, north-slope roofs stay shaded and damp long enough that moss and dry rot hide at valley and flashing details a valley roofer never checks. Just blocks away, canyon-edge homes get WUI inspection and insurance scrutiny that pushes Class A assemblies and ember-resistant vents. The shingle brand is the same; the failure profile is not. We quote the roof we’re standing on, not the roof we assume from a satellite photo. Whether it’s Mayflower Village CertainTeed service or work right here in Monrovia, we assess what’s actually in front of us.
On a 1920s Craftsman bungalow off North Myrtle Avenue, our crew pulled three layers of old roofing and found skip-sheathing and dry-rotted fascia under a Landmark field that had been moss-covered for years on the shaded north slope. We replaced the decking, rebuilt the fascia, and re-roofed with CertainTeed Landmark and Flintlastic SA underlayment, adding ember-resistant vents to satisfy the WUI detail the owner’s insurer flagged. That’s Monrovia roofing, and we’ve done it enough to quote it accurately the first time. This is the kind of local specificity you won’t find on a generic CertainTeed sales & service page.
CertainTeed Models & Products We Service in Monrovia
We service and install the CertainTeed lines most common on Monrovia rooftops: Landmark architectural shingles, XT 25 three-tabs, NorthGate SBS-modified asphalt shingles for lower-slope Craftsman porches, and Flintlastic SA self-adhered underlayment for WUI-classified assemblies. We use CertainTeed OEM shingles, Flintlastic underlayment, and matching ridge caps on partial repairs because color and sealant compatibility matter. If a repair needs aftermarket vents or fasteners, we use quality parts that meet WUI code. Our van carries the common CertainTeed profiles and accessories, which keeps Monrovia turnaround tight without a warehouse run to Irwindale every time.

AfterCertainTeed Service Pricing in Monrovia
CertainTeed roofing costs in Monrovia depend on the scope, not the brand name alone. Here’s what drives the price:
- Shingle replacement (spot repair): A single wind-creased Landmark shingle or a small granule-loss patch typically runs $200 to $500 in Monrovia, depending on the slope, access, and whether we’re also repairing flashing or underlayment.
- Full CertainTeed Landmark re-roof: Most Monrovia homes land between $9,000 and $16,000 for a complete tear-off and Landmark installation with Flintlastic SA underlayment. Foothill parcels with steep slopes, skip-sheathing repairs, or WUI upgrades run higher.
- Roof decking replacement: If tear-off reveals rotted decking, we quote it separately. Monrovia’s older homes often need $800 to $2,500 in decking and fascia work before new shingles go down.
Every free estimate includes a written line-item quote with the exact CertainTeed products we propose, so you know where the money goes. Call (833) 467-4846 for a Monrovia quote. It takes about an hour, and you get a number you can hold us to.

FAQs – CertainTeed Roofing in Monrovia
Yes, if the crease is isolated and the surrounding field still has sealant integrity and granule coverage. We’ll lift the damaged shingle, check the nail line and underlayment beneath it, and install a matching CertainTeed OEM replacement. If the crease signals broader sealant failure from a bad install or age, we’ll tell you that instead. Call (833) 467-4846 for an inspection and a repair-versus-replace recommendation.
CertainTeed Landmark shingles carry a Class A fire rating, which is the shingle component of a WUI-compliant roof assembly. But Monrovia’s wildland-urban interface zones also require fire-rated underlayment and ember-resistant vents at eaves and gable ends. If your insurer flagged your roof, we’ll inspect the whole assembly, not just the shingles. Call (833) 467-4846 to schedule an inspection.
It’s the shade. North of Foothill Blvd, north-slope roofs in Monrovia stay damp well into the afternoon, especially in winter. That shade holds moisture long enough for moss to colonize Landmark shingles at the valleys and chimney flashing. Your neighbor on a south-facing slope gets full sun by mid-morning, which dries the roof and prevents moss. We remove moss mechanically and treat the roof, then check for the dry rot that always follows. Call (833) 467-4846 for an assessment.
You should expect the tear-off to uncover more than shingles. Monrovia’s Craftsman bungalows and 1950s ranches were often built with skip-sheathing, which leaves gaps between boards. Modern CertainTeed shingles need solid decking underneath, so we’ll quote sheathing replacement as part of the re-roof. We also expect dry-rotted fascia and rafter tails on many of these homes. We’ll show you what we find before we install the new roof. Call (833) 467-4846 to schedule a free estimate.
For most Monrovia homes, especially those in the foothill and canyon zones, yes. Flintlastic SA is a self-adhered underlayment that seals around fasteners and resists wind-driven rain better than standard felt or synthetic underlayment. It’s also a fire-rated component many Monrovia insurers want to see. On a shaded north-slope roof, it adds a second line of defense against the damp that causes decking rot. Call (833) 467-4846 and we’ll walk you through the cost difference on your specific roof.
