CertainTeed Roofing in Maywood, CA | Buena Park Roof Repair
We provide independent CertainTeed roofing service across Maywood, and the one thing that separates our work here is this: we know Maywood’s flat-roofed stucco bungalows and their add-on rooms fail at the transitions and tie-ins, not in the middle of the shingle field. We’re not a CertainTeed dealer, and we’re not authorized by the manufacturer. What we are is a crew that has torn off and repaired enough CertainTeed Flintlastic and Landmark systems in Maywood to know exactly where they break under inland sun and how to fix them without pushing a full replacement when a patch-and-coat will hold. Call (866) 282-5070 for a straight assessment.
Why Maywood Residents Choose Us for CertainTeed Service
Most roofing companies in southeast LA County push whatever shingle brand they have a deal with. We don’t work that way. Our CertainTeed sales & service work sits inside a seven-brand portfolio that includes GAF, Owens Corning, IKO, Atlas, Tamko, and Boral, so when we tell you a CertainTeed repair is the right move, it’s because the material matches what’s already on your roof, not because it’s the only thing we sell. Rick Dunnigan, our owner, grew up patching roofs on old ranch-style homes around Buena Park and built this company on a simple rule: tell the customer what the roof actually needs, even when that answer is a $400 flashing repair instead of a $12,000 re-roof.
For Maywood specifically, that matters more than in most cities. The housing stock here is 1920s to 1950s small stucco bungalows on narrow lots, most with flat or very low-slope roofs, detached garages, and informal room additions that were permitted piecemeal or not at all. Those roofs don’t fail like a big suburban slope roof in Cerritos does. They fail at scuppers, at the flashing where an add-on ties into the main house, and along shared property lines where runoff has nowhere to go. We know those failure points because we’ve chased them down dozens of times in zip code 90270. If you want someone who’ll tell you what’s actually happening up there, not someone sizing up a commission, call us.

Common CertainTeed Roofing Problems We Solve in Maywood
- Blistered and sun-cracked Flintlastic SA on flat additions. Maywood’s summers are brutal on low-slope modified bitumen. The UV cooks Flintlastic caps until they blister, then the first winter storm ponds water in those blisters and leaks through. We see this constantly on the add-on rooms behind small bungalows where the membrane is original or was patched years ago with a non-matching product.
- Leaks at the slope-to-flat transition flashing. A lot of Maywood homes have Landmark architectural shingles on the main house and a flat CertainTeed membrane on an addition. The shingle field holds up fine for 20-plus years. The transition flashing between them doesn’t. That’s where the leak is, almost every time, and it’s usually a flashing detail that was flashed wrong from day one or worn through after decades of thermal movement.
- Wind-lifted XT 25 and XT 30 tabs on older wood-frame homes. These three-tabs were installed on a lot of Maywood’s original 1920s-to-1950s houses, and many have been re-nailed or patched multiple times over the decades. When Santa Ana winds hit, the weakened fastener points let tabs lift at hips and rakes, especially where granules have already worn off.
- Runoff wicking into shared-line flashing. This is a Maywood-specific problem. Lots are so tight that a flat roof’s scupper often drains toward a neighbor’s roof just a few feet away. That water wicks under the flashing at the shared property line and rots the sheathing before anyone sees a ceiling stain.
- Ponding water on low-slope CertainTeed roofs. Maywood’s flat and near-flat roofs pond after rain because the original drainage was never graded properly, and decades of settling haven’t helped. Ponding shortens the life of any Membrane, but on Flintlastic SA it accelerates the blistering cycle dramatically.
CertainTeed Service in Maywood: What Local Conditions Mean for Your Roof
Here’s the thing about Maywood that changes how CertainTeed roofing work gets done here, and it’s not something you’d hear on a generic CertainTeed page. Maywood is one of the densest, most heavily Latino working-class cities in LA County, and almost all its housing is aging small-lot single-family homes with detached garages and additions, many owner-built or permitted piecemeal. The lots are narrow, the setbacks are a few feet at best, and a flat addition’s CertainTeed membrane often drains toward a shared property line. On wider suburban lots, runoff from a flat roof spills into a yard or a gutter. In Maywood, it spills toward the house next door. That means our flashing work here frequently involves re-grading or extending a scupper so runoff doesn’t wick onto the neighbor’s roof a few feet away. It’s a constraint that doesn’t come up in CertainTeed repair in Commerce or La Palma. If you live on one of those tight Maywood lots and your CertainTeed roof leaks at the shared-line flashing, the fix isn’t just slapping on more mastic. It’s re-working the drainage path. We’ve done it enough times off Slauson and Atlantic that we can usually tell you what’s happening before we even get on the ladder.
CertainTeed Models & Products We Service in Maywood
We work on the full CertainTeed residential line you’re likely to find on Maywood roofs: Landmark architectural shingles, XT 25 and XT 30 three-tabs, Flintlastic SA self-adhered modified bitumen for low-slope and flat sections, and DiamondDeck and RoofRunner underlayments. For repairs, we match like-for-like where it keeps the existing system intact, meaning CertainTeed-branded Flintlastic SA membrane, Landmark shingles, and DiamondDeck underlayment on the parts that show or carry load. Elsewhere we use compatible underlayment and flashing metals that do the job without pretending to be OEM. That approach matters in Maywood because a mismatched patch on a Flintlastic flat roof looks bad and fails faster, and on a house where the whole block is stucco bungalows, you notice a patch that doesn’t match.

AfterCertainTeed Service Pricing in Maywood
What you’ll pay depends almost entirely on what’s actually wrong. A scupper re-flash or a small Flintlastic patch on a flat addition runs on the lower end. A transition flashing rebuild where the slope meets the flat roof costs more because it’s fussy, detail-heavy work. A full tear-off and re-roof of a small Maywood bungalow with Landmark shingles and new DiamondDeck underlayment is a bigger number, but it’s also a job we’ll only recommend if the deck is sound. The honest way to price it is to look at the roof first. Our estimates are free, they’re written line-item quotes, and we don’t pad them with change orders later. Call (866) 282-5070 and Rick or one of us will come out and tell you what you’re dealing with.

FAQs – CertainTeed Roofing in Maywood
Yes, in many cases. If the membrane is still adhered and the deck underneath is solid, we can cut out the blistered or cracked section, patch it with matching Flintlastic SA, and coat the field to buy you several more years. Once the deck has soft spots or the field is blistering past repair, another patch is throwing money away, and we’ll tell you that plainly. Call (866) 282-5070 to have us look before you spend.
At the transition flashing where the flat addition ties into the sloped shingle roof. That detail gets flashed wrong on a lot of older Maywood homes, and decades of thermal expansion and contraction pull it apart. The shingle field and the flat membrane can both be in decent shape while that transition leaks, a problem we also see providing CertainTeed service in Huntington Park. That’s where we start looking.
Yes. When a flat CertainTeed roof drains toward a shared property line a few feet away, the flashing at that line takes constant runoff that a wider suburban lot would never send its way. We re-grade or extend scuppers so water moves away from the neighbor’s roof, then flash the shared edge properly. It’s the most common fix we do on Maywood’s narrow lots.
Maywood’s inland summers bake low-slope membranes all day with intense UV and no marine layer to soften it. Flintlastic SA and similar modified bitumen caps dry out, crack, and blister faster here than they would near the coast. Then winter rain ponds in those weakened spots and leaks. The heat doesn’t fail the roof on its own, but it sets up the winter leak.
No. We’re an independent CertainTeed service provider, not affiliated with or authorized by the manufacturer. That means we can be straight with you about whether a CertainTeed product is the right fix for your Maywood roof or whether something else makes more sense, because we’re not tied to their rep or their quota.
