CertainTeed Roofing in Artesia, CA | Spartan Roof Repair
We provide independent CertainTeed roofing service across Artesia, including both 90701 and 90702. We’re not a manufacturer rep, and we’re not authorized by CertainTeed. What we are is a roofing-only crew that has installed and repaired CertainTeed shingle and tile systems on Artesia’s specific housing stock for years, including the low-slope addition roofs that fail in ways a spec sheet never mentions. Call (855) 382-3237 for a straight answer about your CertainTeed roof.
Why Artesia Residents Choose Us for CertainTeed Service
Most Artesia homes we see are 1950s and 60s stucco tract houses on compact lots. A lot of them have rear additions and attached patio covers that share one low-slope roof plane with the main house. That’s not a detail you’ll find in CertainTeed’s product literature, but it changes how shingles, underlayment, and flashing actually perform out here. Our crew knows those roofs because we’ve worked on them repeatedly. Brent Calloway, our owner, learned roofing fundamentals at Orange Coast College’s construction technology program and has spent over two decades on roofs across the southeast LA Basin. He built Spartan Roof Repair on a simple idea: your roof doesn’t need a speech. It needs a fix. We’re CertainTeed sales & service specialists in the practical sense, not the marketing sense. We install it, we repair it, we replace it. And we’ll tell you when a patch makes more sense than a tear-off.

Common CertainTeed Roofing Problems We Solve in Artesia
Here’s what we see repeatedly on CertainTeed roofs in Artesia, tied to how these homes are actually built and how the local climate works on them.
- Granule loss and sealant failure on south-facing Landmark and XT 25 planes. Artesia summers are dry and hot, and the south-facing slopes on 90701 homes take direct sun for hours. On unvented low-slope additions, CertainTeed shingle fields heat up and shed granules faster than the rest of the roof. Sealant strips dry out and let go, and then the first winter wind lifts shingles at the rake.
- Underlayment failing under Spanish tile long before the tile itself. We service certainteed tile systems where the visible clay or concrete tile still looks fine, but the RoofRunner or DiamondDeck underlayment underneath has dried, cracked, and started letting water through. Poor attic ventilation on older Artesia tract homes accelerates it. The leak only shows up when winter rain finally penetrates.
- Vent boot and flashing decay where the patio cover plane meets the house wall. This is the classic Artesia CertainTeed failure. The rear addition and attached patio cover share one roof plane, and where that plane hits the stucco wall, sealant-backed boots and flashing crack in the dry heat. Ponding at the low-slope transition pushes water straight into those cracks.
- Ponding-related blistering and edge curl on near-flat CertainTeed transitions. Flat and very low-slope sections common on Artesia additions don’t shed water quickly. Sun-baked shingle edges and membrane at those transitions blister and curl long before the main field shows wear.
- Patch-over failures from previous repairs. Many Artesia homes have had someone patch a CertainTeed roof without addressing the drainage or underlayment underneath. The patch holds for a season, then the same winter leak returns. We get called when homeowners are tired of paying twice.
CertainTeed Service in Artesia: What Local Conditions Mean for Your Roof
There’s a pattern we see over and over on older Artesia lots in 90701: the rear addition and attached patio cover share one continuous low-slope roof plane with the house. That means a leak near the patio wall is rarely a single point failure. It’s one roof plane draining the wrong way, pushing water against flashing and boots that weren’t designed for standing water. When we get a winter rain call from a CertainTeed shingle roof in Artesia, our first question is whether the patio plane has positive slope to a drain or scupper. More often than not, it doesn’t. The fix usually involves rebuilding flashing at the wall transition, replacing cracked vent boots, and correcting the drainage so water stops pooling at the low point. None of that shows up in a generic CertainTeed service description. But it’s what actually solves the problem for Artesia homeowners, and it’s the difference between a repair that lasts and one that leaks again next February. We specialize in leak repair, flat roof patch, and tile underlayment replacement for exactly this reason.
CertainTeed Models & Products We Service in Artesia
We work with the full range of CertainTeed roofing systems common in Artesia. That includes Landmark architectural shingles, XT 25 three-tab shingles, Presidential Shake and Presidential T/L, and CertainTeed clay and concrete tile underlayment systems like DiamondDeck and RoofRunner. For parts, we take a practical approach. We match CertainTeed accessories and underlayment to the existing system where it’s still serviceable, and we use quality aftermarket boots and flashing where the OEM part adds nothing but cost. We stock common CertainTeed profiles and accessory lines for faster turnaround on Artesia jobs, which means less waiting between diagnosis and fix. Seven of the industry’s most trusted roofing brands sit on our trucks and in our material orders, because no single brand is right for every Artesia roof. Roofing specialists, not generalists.

AfterCertainTeed Service Pricing in Artesia
CertainTeed roof repair in Artesia depends on what’s actually wrong, and we quote by the line item, not by the square foot of hope.

Repairing flashing and boots at a shared low-slope plane typically lands between $450 and $900. Tile underlayment replacement on a small Artesia patio cover runs roughly $1,200 to $2,800, while underlayment for a full Spanish-tile roof can range from $6,500 to $18,000 depending on square footage and decking condition. Matching a CertainTeed shingle patch usually costs between $400 and $1,200 for the patch itself, plus any decking or underlayment work if we find rot underneath. Every quote we give is written, line-by-line, and tied to what we actually found on your roof. Call (855) 382-3237 for a free estimate.

FAQs – CertainTeed Roofing in Artesia
We install CertainTeed shingles and accessories on low-slope Artesia additions, but flat and near-flat planes require a different approach than standard-pitch roofs. On those sections we address drainage first, then choose a product that can handle ponding. Some shingle products are not rated for low-slope applications, so we’ll recommend the right material for that specific plane rather than forcing a name-brand shingle where it doesn’t belong. Call (855) 382-3237 for an exact assessment and quote.
Winter-only leaks on certainteed tile roofs in Artesia almost always point to failed underlayment, not failed tile. The clay or concrete tile looks intact, but the DiamondDeck or RoofRunner underneath has dried and cracked during the summer heat, and winter rain finds its way through. In our experience, this is the single most common source of winter ceiling stains on Spanish-tile homes in 90701 and 90702. The fix is underlayment replacement, not tile replacement. Call (855) 382-3237 and we’ll confirm what’s actually failing before recommending any work.
Yes, in most cases we can match existing CertainTeed shingles for a patch. We match both the profile and the color to what’s on the roof, including Landmark architectural profiles and XT 25 three-tab where it’s still available. The challenge comes when the roof has been exposed to Artesia sun long enough that the original color has faded, and any new shingle will read slightly different at first. That fade usually blends within a season or two. We’ll show you the match before we install it.
The leak returns because the roof plane hasn’t been fixed, only the surface has. On many Artesia homes the rear addition and attached patio cover share one low-slope plane with the house, and water ponds at the wall transition. Someone patches the shingles, but the drainage problem and the cracked flashing at the wall remain, so the next winter storm pushes water through the same weak point. Fixing it permanently means correcting the slope, rebuilding the flashing, and sealing the boots. That’s the repair we specialize in. Call (855) 382-3237 for an estimate.
We use CertainTeed DiamondDeck and RoofRunner underlayment systems, matched to the existing tile profile and the roof’s slope. For Artesia homes where the original underlayment has dried out under Spanish tile, we remove the tile, replace the underlayment, and re-set the original tile if it’s still sound. That keeps the roof’s appearance intact while fixing the actual water barrier. Estimates are free, and we’ll tell you before we start whether the tile itself needs replacement or can be reused.
