CertainTeed Roofing in Westmont, CA | Tilecraft Roofing
We provide independent CertainTeed roofing service across Westmont and nearby communities like View Park-Windsor Hills, from Landmark shingle repairs to flat-roof membrane patching on mid-century stucco homes and low-rise apartments. What makes our CertainTeed work here different is straightforward: we’ve spent years watching how these specific products fail under Westmont’s dry, hot summers and first-rain leak patterns. If you need a CertainTeed roof inspected, patched, or replaced, call (833) 467-4846 for a free estimate.
Tilecraft Roofing works with seven major roofing brands, including CertainTeed. That matters because we’re not a one-brand shop trying to sell you whatever we stock. We’re an independent CertainTeed sales & service provider, not authorized or sponsored by CertainTeed. We look before we quote. When a patch is the right fix, we patch. When the field is gone, we tell you that too.
Why Westmont Residents Choose Us for CertainTeed Service
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’s construction technology program before spending years on residential and commercial roofs across the Southeast LA corridor, including CertainTeed in West Athens. That background means something specific when you call about a CertainTeed roof in Westmont: we know what these roofs looked like when they were installed in the 1950s and 60s, and we know what they look like now.
Most Westmont homes sit on post-war stucco frames with flat or low-slope roofs. CertainTeed’s rolled roofing and built-up membranes were standard on many of those original installs. We still match them today with like-for-like CertainTeed products where they’re available, and quality equivalents where they’re not. Seven leading brands, one crew. The right material for your roof, not whatever’s left in the truck.

Common CertainTeed Roofing Problems We Solve in Westmont
- Brittle Landmark shingles on sun-baked slopes. South and west-facing roof planes in Westmont take relentless UV for eight months a year. CertainTeed Landmark architectural shingles on those exposures lose granules early and go brittle long before the warranty window closes. We see it constantly on pitched townhome roofs.
- Curling X(T)-series organic shingles on 1950s-60s stucco homes. The older organic-mat CertainTeed shingles dry-crack and curl under thermal cycling. Sealed tabs pop open, and wind-driven rain finds the deck. These homes aren’t leaking because the roofer was sloppy; they’re leaking because the material is 60 years old.
- Alligatored flat membranes on low-rise apartment buildings. CertainTeed rolled roofing and modified bitumen expand and contract through every hot summer day. Over decades, the surface alligators and seams split. Apartment owners in Westmont know the pattern: a dry roof all summer, then a ceiling stain in January.
- Hardened flashing and vent boots around skylights and rooftop vents. Original CertainTeed flashing details on 1960s homes harden in the heat and pull away. The leak stays hidden during the dry season because there’s no water to find it. After the first real winter rain, the calls start.
- Failed patches from mismatched brands. We regularly see Westmont roofs where a previous contractor patched a CertainTeed field with a different manufacturer’s shingle or membrane. The color’s off, the granule profile’s wrong, and the patch fails early because the materials expand at different rates. We match like-for-like.
CertainTeed Service in Westmont: What Local Conditions Mean for Your Equipment
Westmont’s flat and low-slope CertainTeed rolled roofs sit through long, dry summers, so the leaking only shows up after the first significant winter rain. That means our busiest CertainTeed patch-and-flashing calls cluster in the week the rains return, not during the dry season. Here’s what that looks like on the ground: after the first winter storm this season we got called to a 1960s single-story stucco home in the Westmont area off 90047 where a rooftop vent had been quietly leaking into the ceiling all dry season. The original CertainTeed rolled membrane had alligatored at the seams and the vent boot had hardened and pulled loose, so we patched the split flat sections, reset the flashing, and replaced the boot. The ceiling stayed dry through the next downpour. The roof either does its job or it doesn’t. Let’s make sure it does.
That timing matters for Westmont homeowners. You won’t see the leak in August. You’ll see it the week after the first storm in November or December. If you wait until then, we’ll be on a roof somewhere else in the 90047 ZIP with the same problem. The best time to have a CertainTeed flat roof inspected in Westmont is September or October, before the rains return.
CertainTeed Models & Products We Service in Westmont
We service the CertainTeed product lines most common in Westmont: Landmark architectural shingles, X(T) 25 and X(T) 30 organic-mat shingles on older homes, CertainTeed rolled roofing and modified bitumen membranes on flat and low-slope structures, and NorthGate and Patriot colonial-slate style shingles on later townhomes. When we repair a CertainTeed roof, we match like-for-like rather than forcing a mismatched brand onto a repairable field. We use underlayments and flashing that meet or exceed the original spec.
For Westmont turnaround, we keep common CertainTeed repair materials on hand: matching Landmark colors, rolled membrane patch stock, vent boots, and flashing profiles. That means a flat roof patch or vent boot replacement doesn’t sit waiting on a special order.

AfterCertainTeed Service Pricing in Westmont
What you’ll pay depends on what we find. A vent boot replacement on a Westmont stucco home is a smaller job than seam-splitting across a low-rise apartment membrane. That said, here’s what most CertainTeed service falls into:
- Vent boot repair or replacement: $250 – $500 per boot, depending on access and the condition of surrounding flashing.
- Flat roof patch (CertainTeed rolled or mod-bit): $450 – $900 per section, including seam prep and surface primer.
- Landmark partial shingle repair: $350 – $800, depending on slope, field size, and whether we need to open and reseal surrounding tabs.
- Full CertainTeed replacement (pitched townhome, Landmark): $9,500 – $16,000, per roof. We’ll scope it only when the field is genuinely past service life.
- Full CertainTeed flat roof replacement (small apartment or single-story): $12,000 – $22,000, depending on deck condition and membrane system selected.
Every estimate includes a written line-item scope. We look before we quote. That’s the whole point. Call (833) 467-4846 and we’ll schedule a free inspection and estimate in Westmont.

FAQs – CertainTeed Roofing in Westmont
The leak exists all summer, but there’s no water to expose it. Westmont’s dry season hides seam splits, alligatored membrane, and pulled flashing because nothing tests them. When the first storm arrives, water finally enters wherever the roof has opened up. That’s why we recommend a pre-rain inspection in September or October. Call (833) 467-4846 to schedule one before the clouds do.
Depends on the membrane’s condition. If the alligatoring is surface-level and seams are intact, a patch buys you time. If seams are splitting across multiple sections and the surface is cracking through to the reinforcing mat, patching becomes a recurring bill. We’ll tell you honestly which situation you’re in. The estimate is free at (833) 467-4846.
Usually, yes. CertainTeed Landmark colors are still readily available, and we keep common Westmont colorways in stock. For older or discontinued color lots, we’ll match as closely as the market allows and tell you up front if the repair will be visible. You deserve to know before we start.
Most often it’s the flashing. On 1960s Westmont homes with original skylights and rooftop vents, the CertainTeed membrane may be fine while the flashing has hardened, cracked, or pulled away from the curb. We always assess both. Sometimes it’s a $400 flashing reset. Sometimes the membrane around it has alligatored and needs a patch too. We’ll show you photos before quoting anything.
We work on the full range of CertainTeed roofing products, including metal panel systems and concrete tile lines where they’re installed in Westmont. Boral’s in our material portfolio as well, which means tile and specialty work isn’t foreign to us. If you have something unusual, call (833) 467-4846 and describe it. We’ll tell you if we’re the right crew for it.
