CertainTeed Roofing: The Los Angeles Owner’s Guide
We stock and install CertainTeed-compatible roofing across Los Angeles, with most accessory and component swaps running $470 – $2,125 installed depending on what failed and where. If you’re seeing water stains on the ceiling that trace back to a cracked vent boot or failed flashing, you’ll usually find us on site within a couple of days with the right part in hand. You generally discover a failed CertainTeed part not from climbing a ladder, but from a drip that starts small and shows up indoors first, often weeks after the actual crack happened.
Trevor Nash has pulled apart enough CertainTeed systems in his two decades working residential jobs across the Basin to know one thing: the shingle rarely fails first. It’s the parts around it. The pipe collar, the ridge vent, the valley metal, the starter strip. Those are the pieces that crack, lift, or corrode while the shingle itself still has years in it.
Which CertainTeed Models This Applies To

CertainTeed organizes its roofing lines into three families that matter for matching parts: the Landmark series (asphalt laminate shingles), the Presidential Shake series (the heavy, multi-layered look), and their metal and membrane lines used on low-slope Los Angeles roofs. Within Landmark, the Pro, Premium, and Solaris grades share the same accessory ecosystem, so a ridge cap or vent boot rated for Landmark Pro also works on Landmark Premium. The Presidential line uses a thicker profile, which means its hip and ridge accessories are not interchangeable with standard Landmark pieces.
The practical gotcha we see in Los Angeles: CertainTeed’s Integrity Roof System is a warranty package, not a physical spec. If you install a mix of aftermarket flashing with CertainTeed shingles, you don’t get the system warranty, only the shingle material warranty. For some homeowners that matters, for others the savings on quality aftermarket accessories makes more sense. We’ll walk through that trade-off in plain numbers before you commit to anything.
To identify your exact part, look at the shingle’s underside or the packaging label for the series name and color code. CertainTeed prints the color lot on the wrapper, and that number matters if we’re blending a repair into an existing roof rather than replacing a full run.
Styles & brands we work with







Signs Your CertainTeed Roofing Is Failing
- Water staining on ceilings or walls, especially after a week of Santa Anas or heavy coastal fog. This is almost always a failed pipe boot or vent collar, not a shingle. The rubber gasket around the pipe dries and cracks in LA’s UV and heat, then splits where you can’t see it from the ground.
- Granules collecting in gutters or at the base of a downspout. CertainTeed asphalt shingles shed granules as they age, but a sudden heavy deposit usually means an impact hit or a section that’s delaminating. In neighborhoods like Northridge or Granada Hills where oak branches overhang roofs, we find this often.
- Curling at shingle edges or lifted tabs after a heat spell. The tile-roofed homes of the Valley hold up, but asphalt laminate in the San Fernando Valley can curl when attic ventilation isn’t moving heat out. The shingle isn’t defective; the ridge vent is underperforming and the whole roof is cooking from underneath.
- Flashing that’s pulling away from walls, skylights, or chimneys. In older Los Angeles neighborhoods like West Adams or Echo Park, the original metal step flashing corrodes and separates. CertainTeed’s warranty covers shingles, not the metal around them, so this is a fix we handle frequently.
- Interior musty odor with no visible drip. That’s moisture trapped in the decking (the plywood layer under the shingles). It usually traces back to a slow leak at a nail penetration or a valley that’s catching debris and holding water against the underlayment.

AfterReplacement Cost & What’s Included

For Los Angeles homeowners, a component-level CertainTeed repair, meaning flashing, boots, vents, or isolated shingle replacement, runs $470 – $2,125 installed. A full roof replacement with CertainTeed product lands between $9,440 and $23,600, driven by roof size, pitch, tear-off depth, and whether you’re on the Landmark or Presidential line.
What moves the number on a repair: access (a two-story home in Highland Park costs more in labor than a ranch in Torrance), layers underneath (if we’re cutting through three layers of old roofing to reach the decking, that’s more time), and part type (aftermarket flashing runs less than CertainTeed OEM, but may affect the system warranty). We give you that breakdown in writing before we start, so you know exactly what’s parts, what’s labor, and what the guarantee covers.
Every repair includes our 365-Day Done Right Promise: if the fix fails inside a year, we return and make it right at no charge. That’s in writing on every job, not a verbal handshake.

DIY or Call Us?
If you want to know what you’re dealing with before calling, you can safely do this: from the ground or a ladder (never on the roof itself), look for lifted shingle tabs, visible cracks in pipe boots, or flashing that’s separating from a wall. A pair of binoculars works, and keeps you off a Los Angeles roof that’s been baking in the sun and can be slick with coastal residue.
What we don’t recommend: climbing onto a two-story roof to peel back shingles. Steep-pitch Los Angeles roofs aren’t worth a fall, and the moment you start pulling nails or prying flashing, you’ve got a bigger repair than you started with. Roof work, especially anything involving the decking or the underlayment, is genuinely dangerous without training and fall protection. If you’ve spotted the problem, call us at (213) 277-6578 and we’ll put eyes on it, give you a written price, then pick up the tools.
FAQs

Landmark asphalt shingles typically hold up 20 to 28 years in Los Angeles, but our UV exposure, heat, and the dry-then-rain cycle mean the accessories around them often need attention at year 12 to 15. The shingle itself may still be sound while the pipe boot or ridge vent has already failed. Call (213) 277-6578 and we’ll tell you what’s still got life in it and what doesn’t.
Yes, most component failures (flashing, boots, individual shingles) can be repaired without touching the rest of the roof, and that’s usually the $470 to $2,125 range we mentioned. What can’t be repaired is a shingle that’s delaminated through its mat or decking that’s rotted from a long-running leak; those need section replacement. We give you the repair-versus-replace trade-off in writing before any work starts.
Most component repairs take a half day, including getting the old part out, checking the decking underneath, and sealing everything back. Full roof replacements on a standard Los Angeles home run three to five working days. We’ll give you a defined arrival window and keep the job site clean while we’re on it, which is part of how Penhallow has operated under The Kingswell Way since 2004.
We stock common CertainTeed-compatible accessories on the truck right now: pipe boots, ridge caps, starter strips, and standard flashing in the colors most Los Angeles homes use. Special-order pieces (CertainTeed OEM color-matched trim or Presidential-specific components) take a few days from our supplier. We also stock parts for KraftMaid, Cambria, and Silestone products when a roofing repair crosses into renovation work.
