Why San Marino Residents Choose Us for CertainTeed Service

CertainTeed makes a broad range of roofing materials, from Landmark architectural shingles to the heavier Grand Manor and Presidential Shake lines, plus the underlayment components that sit beneath concrete and clay tile. That range matters in San Marino because the housing stock here is not uniform. Spanish Colonial Revival and Mediterranean estates from the 1910s through the 1940s often carry original or decades-old tile roofs. Newer homes and additions lean toward architectural asphalt. Having worked across the San Gabriel Valley for years, we have handled both, and we understand how each performs under the specific heat, UV exposure, and winter rain cycles this city gets at the foot of the San Gabriels.

Ron Thibodeau founded Marquis Roof Repair after more than two decades of roofing work across the San Fernando Valley and the San Gabriel Valley. He grew up around general contracting in Burbank, where his uncle ran jobs out of a pickup truck, and he learned early that shortcuts always show up eventually. That is the standard we bring to CertainTeed service in San Marino: methodical diagnosis, honest recommendations, and repairs that hold. We are an independent CertainTeed service provider, which means we are not authorized, sponsored, or warrantied by CertainTeed. We tell San Marino homeowners plainly what their existing roof can and cannot be saved.

Common CertainTeed Roofing Problems We Solve in San Marino

• Failed tile underlayment beneath reusable historic tile. Under original clay tile roofs from the 1920s and 1930s, we routinely find CertainTeed or older felt underlayment that has dried, cracked, and lost its seal after eight decades of thermal cycling. The tile looks fine from the street. The waterproofing layer is gone. We lift the tile, replace the underlayment and battens, and re-lay the salvaged tile to its original coursing.
• Granule loss and edge curling on south- and west-facing shingle slopes. San Marino gets long dry stretches with intense UV. CertainTeed architectural shingles on slopes that face the afternoon sun age faster than the manufacturer’s nominal life, especially above mature estate landscaping where tree canopies hold heat and block drying airflow. We see granule loss and curling most often on these exposures.
• Rusted or nail-sick battens and fasteners under concrete tile. Decades of thermal expansion and contraction work loose the fasteners that hold tile in place. When an atmospheric-river storm comes off the San Gabriels, wind-driven rain finds those gaps. We replace battens and re-secure tile before it becomes a leak.
• Valley and flashing failures on multi-ridge, dormered rooflines. San Marino’s estate homes frequently have complicated roof geometry. Debris from the foothills collects where transitions meet, holds moisture against flashing, and accelerates corrosion. We reset and replace valley flashing details as part of nearly every major repair here.
• Underlayment deterioration from decades of thermal stress on tile roofs. Even when tile is intact and battens are sound, the underlayment itself breaks down over time. Hot summers followed by soaking winter rains push water through micro-tears. We catch this during inspections and replace the underlayment before interior damage appears.

CertainTeed Service in San Marino: What Local Conditions Mean for Your Roof

San Marino is a city of architecturally significant estates, many designed by prominent Pasadena-area architects in the 1910s through the 1930s. That matters enormously for CertainTeed service here. The city’s design-review and cultural-heritage review processes scrutinize visible roofing materials. Tile-matching, color, and profile often drive the project as much as waterproofing. In a neighborhood like the estates off Oak Knoll Avenue, a homeowner cannot simply swap a faded clay tile field for a quick asphalt overlay. The replacement has to match the original profile and coursing before a permit moves forward. This is a fundamentally different job than the quick overlays common in neighboring San Gabriel or CertainTeed repair in Alhambra. For CertainTeed owners, that means material selection is a stewardship exercise first and a roofing decision second. We handle both layers: the historic matching the city requires, and the watertight assembly the house actually needs.

CertainTeed Models & Products We Service in San Marino

We service the CertainTeed product lines most common in San Marino, including Landmark architectural asphalt shingles, the heavier Grand Manor and Presidential Shake luxury shingle lines, and the underlayment and tile accessory systems that sit beneath concrete and clay tile. For repairs on existing CertainTeed systems, we use genuine CertainTeed components where the assembly is being extended or patched. Matching shingles, underlayment, and accessory flashing keep the system performing as designed. Where aftermarket underlayment or battens meet or exceed the original spec, we use them and tell you why. We do not push a full tear-off when the tile is reusable and the roof structure is sound. That said, if a CertainTeed shingle field is too far gone to patch, we will say so plainly rather than sell a repair that will not hold.
