Fontana occupies the western San Bernardino County valley floor between Ontario and the city of San Bernardino, with a housing stock that reflects the city's rapid growth from the 1970s through the 2000s. The dominant residential construction era produced tract homes with concrete tile and composition shingle roofs that are now 25–45 years old — the age range where underlayment failure is the most common roofing problem in the Inland Empire's heat. Fontana's position on the valley floor means it absorbs some of the highest sustained summer temperatures in the region, with afternoon heat regularly pushing past 110°F in peak summer weeks. The city also has a large industrial and logistics property base along the I-10 and I-15 corridors, creating significant demand for low-slope membrane roofing on warehouses and distribution facilities.

Fontana's summer temperatures regularly exceed 110°F for multiple weeks each year. That sustained heat bakes the felt underlayment beneath concrete tile from below through the attic and from above through the tile itself. A tile roof installed in 1988 or 1995 may look fine from the street while the underlayment has been compromised for years. Re-roofing in Fontana almost always means full underlayment replacement, not just tile reset.
The city's large warehouse and distribution facilities along the I-10 and I-15 corridors carry flat and low-slope roofs with significant square footage. Dark membrane surfaces on these buildings reach extreme temperatures in Fontana's summer heat, accelerating seam separation and membrane brittleness. TPO's white reflective surface is the most common specification for new installs on these properties because it reduces surface temperature and heat gain into the building.
Shingle roofs in Fontana's older neighborhoods near the city center face a different failure pattern than tile. Asphalt granule loss from UV exposure is the primary aging mechanism, and it happens faster in Fontana's intense sun than product lifespan ratings — written for average national conditions — suggest. A shingle roof that looks thin and gray from the ground is typically past the point where repairs extend its useful life.
At a glance
Concrete tile re-roofs are the highest-demand service in Fontana because the city's large 1980s–1990s residential inventory is now at the age where felt underlayment has degraded from sustained heat, even when tile surfaces appear undamaged. Shingle re-roofs serve the older residential areas near downtown Fontana where composition shingle was the original material and is now well past its rated lifespan in the valley's extreme UV environment. Low-slope membrane installs and repairs — TPO and modified bitumen — cover the city's extensive warehouse and logistics facilities along the I-10 and I-15 corridors. Roof repairs after Santa Ana wind events are common across all property types, particularly ridge cap displacement on concrete tile homes.

Common questions from Fontana, CA customers about our services, process, and coverage.
Fontana's sustained summer heat — regularly above 110°F — degrades felt underlayment faster than in cooler climates. The tile itself is durable and may look intact, but the felt beneath it absorbs heat from both the attic below and the tile above, breaking down in 15–25 years. Once the underlayment fails, any water that gets under the tile through cracked mortar or displaced ridge cap has no secondary barrier.
Concrete tile remains the most practical choice for most Fontana residential properties because it is non-combustible, handles thermal cycling well, and matches the surrounding neighborhood profile. Standing seam metal is a strong alternative for homeowners who want a longer-term system with minimal maintenance. Architectural shingles are an option on lower-pitch roofs where tile is not structurally appropriate. We cover all three in the written quote so you can compare.
Yes. Fontana's I-10 and I-15 corridors have a large concentration of warehouses, distribution centers, and industrial facilities with flat and low-slope roofs. We install and repair TPO, EPDM, and modified bitumen membrane systems on commercial properties and quote the scope in writing before any work begins.
If the shingles are losing granules, showing cracking or curling tabs, or the roof is more than 20 years old in Fontana's UV environment, spot repairs typically delay rather than solve the problem. A full re-roof replaces the underlayment and decking where needed, giving the new shingle layer a sound base. We assess the current condition and give you a clear recommendation in the written quote.
