Why Fontana Residents Choose Us for CertainTeed Service

Noel Fierro learned roofing the slow way: years on rooftops across San Bernardino County, watching the High Desert and Inland Empire punish every material manufacturers ship. That experience matters when you’re dealing with CertainTeed products in Glen Avon and Fontana, because this city’s inland heat and Santa Ana winds create failure patterns you won’t find in coastal neighborhoods. We’re an independent contractor, not a manufacturer-authorized dealer, so our recommendation is based on what your roof actually needs. We work with all seven major roofing brands, including CertainTeed, Owens Corning, GAF, IKO, Atlas, Tamko, and Boral. That means when we tell you a CertainTeed Landmark roof needs replacement instead of repair, it’s an honest assessment, not inventory pressure. We inspect first, then recommend. The roof doesn’t lie, and neither do we.

Our CertainTeed sales & service work across Fontana covers everything from single shingle replacements to full tear-offs. We’re roofing specialists, not general contractors dabbling in exteriors. Every tech on our crew works roofs all day, every day.

Common CertainTeed Roofing Problems We Solve in Fontana

CertainTeed makes solid products. Fontana’s climate tests them hard. Here’s what we see most often on the CertainTeed roofs we service in Pedley and this city:

• Heat-driven granule loss on Landmark shingles. Fontana summers regularly hit the 100s, and that sustained UV exposure accelerates granule shedding on Landmark and Landmark Pro architectural shingles. By year 12 to 15, many Fontana roofs show significant granule loss on south-facing slopes. We inspect granule depth, not just visual wear, before advising repair versus replacement.
• Santa Ana ridge-cap lift on windward slopes. In the north-side foothill subdivisions of 92336 and 92337, dry Santa Ana winds peel ridge caps and rake-edge shingles on the windward side. This is a Fontana-specific pattern, especially in the newer subdivisions built into the foothill terrain. We re-nail and reseal ridge caps after big wind events before leaks ever start.
• Seal-strip failure and wind-driven grit under tabs. Near the washes and wind-scoured streets in the flat older core, dust and grit work their way under shingle tabs and weaken seal strips. Once the seal strip fails, the next Santa Ana lifts the tabs. We see this most often on older CertainTeed XT 25 three-tab roofs from the 1990s and early 2000s.
• Skipped postwar underlayment causing premature top-layer failure. Many 1950s-60s Fontana tract homes in 92335 were built fast, without proper underlayment. When a previous owner put CertainTeed shingles over that skipped deck protection, the top layer fails years before it should have. We strip it down, replace the sheathing, and rebuild properly.
• Thermal cycling cracks in flashing and vent boots. Fontana’s hot days and cool nights create expansion and contraction cycles that crack old flashing seals. On CertainTeed roofs, we often find leaking vent boots and failed pipe collars on the southern and western slopes, which get the most direct heat.

CertainTeed Service in Fontana: What Local Conditions Mean for Your Roof

Fontana’s two build eras sit on two different code and material realities, and that fact changes how a CertainTeed job plays out here more than any other single factor. The 1950s-60s postwar stucco tracts in 92335 were built with tar-and-gravel or modified-bitumen low-slope roofs, and they often skipped underlayment entirely. When one of those homes gets a CertainTeed shingle roof, it’s not a straightforward reshingle. It’s a decking-and-underlayment rebuild. We’ve opened up decks in central Fontana and found original sheathing that predates modern plywood standards, sitting right over skipped felt. In the 1980s-2000s north-side homes in 92336 and 92337, the situation is different. Those houses were built on pitched roofs with proper underlayment already installed. A CertainTeed reshingle there is cleaner, faster, and less expensive. The city’s position on the alluvial fan at the base of the San Gabriels, plus its industrial history around the old Kaiser Steel mill site, means wind-driven dust and inland heat, not coastal marine air, drive roofing wear here. We’ve stripped roofs in Fontana where the dust alone had worked its way between deck seams and slowly abraded the underlayment from the inside.

On a north-side home near the foothill subdivisions in 92337, a Santa Ana wind event had peeled back ridge caps and lifted rake-edge Landmark shingles on the windward slope. Our tech re-nailed the ridge caps, replaced the torn shingles, and resealed the tabs instead of waiting for a leak call. In the older core off 92335, a postwar tract home’s flat roof had been re-covered with CertainTeed shingles over original skipped underlayment, so we stripped it, replaced the exposed sheathing, and rebuilt with proper deck protection before reshingling. Two ZIP codes, two completely different jobs.

CertainTeed Models & Products We Service in Fontana

We service the full CertainTeed residential line that Fontana homes actually have on them. That includes Landmark, Landmark Pro, and Landmark IR architectural shingles, XT 25 and XTG three-tab shingles from older replacements, Presidential Shake and Presidential Solaris, and CertainTeed tile underlayments and roof-deck protection accessory lines on the north-side tile roofs. When a repair needs matching shingles, we use genuine CertainTeed product for Landmark color and profile continuity. For flashing, vent boots, and some accessories, we’ll use quality aftermarket parts where they perform better or match what’s already installed. We keep common CertainTeed Landmark colors stocked locally for fast Fontana turnaround, so a repair doesn’t stall waiting on a shipment.

FAQs – CertainTeed Roofing in Fontana

My CertainTeed Landmark shingles lost granules fast in Fontana heat – is that a defect or just the climate?

In almost every Fontana case we see, it’s the climate. Sustained 100-degree summers and intense UV exposure accelerate granule loss on any asphalt shingle, including CertainTeed. Landmark is a quality product, but Fontana’s south-facing slopes take a beating. We can measure granule depth and tell you honestly whether you’re looking at normal wear or a potential warranty issue. Call (866) 942-0875 for an inspection, no obligation.

Why do CertainTeed shingles on the windward slopes in the north foothill subdivisions lift after big winds?

Santa Ana winds off the San Gabriels hit the windward slopes in 92336 and 92337 with sustained force that eventually breaks seal strips and lifts rake-edge shingles. It’s not a CertainTeed defect. It’s a local wind pattern. We address it by re-nailing ridge caps and resealing tabs, and we recommend an inspection after major wind events before small lifts become full leaks.

Can you match my existing CertainTeed shingles for a repair?

Yes. We match Landmark and Landmark Pro colors using the same product lines so the repaired area blends with the existing roof. For older CertainTeed products that are no longer manufactured, we’ll find the closest available match and tell you before we install anything.

My 1950s Fontana home in 92335 has original decking under the shingles – what should we expect during replacement?

Expect the decking to need at least partial replacement. Homes built during Fontana’s postwar boom often used thinner sheathing and skipped underlayment, which decades of heat and dust have degraded. We’ll open it up, show you what’s there, and include decking replacement in the quote before work starts, not as a surprise after.

Do you handle CertainTeed tile underlayment on the older tile roofs in Fontana’s north side?

Yes. Tile roofs on the 1980s-2000s north-side homes eventually need underlayment replacement, even when the tile itself is still sound. We use CertainTeed roof-deck protection products where appropriate and handle the full tile re-lay. Call (866) 942-0875 for an exact quote, estimates are free.
