AJ Roofing & Repair | Roofing Services in Upland, CA 91786

In Upland, the primary culprits are our intense, year-round sun and significant temperature swings. The sun's UV rays can dry out and degrade roofing membranes over time, making them brittle and prone to cracking. Meanwhile, thermal expansion and contraction from hot days and cooler nights can cause metal flashings around chimneys and vents to warp or lift, creating potential leak points. Our inspections specifically look for these local wear patterns.

It depends on the extent of the damage. For isolated cracks or small affected areas, our team can often perform a targeted, durable repair by sealing the crack and reinforcing the surrounding membrane. However, if the cracking is widespread or the membrane shows signs of overall aging and brittleness, a partial or full replacement with a new, UV-resistant membrane may be the more reliable and cost-effective long-term solution. We provide a clear, honest assessment to help you decide.

Fixing lifted flashing is a critical repair. Our process involves carefully removing the compromised flashing, inspecting the underlying deck for water damage, and preparing a clean surface. We then install new, high-grade flashing material, securely fastening it and sealing all seams and edges with a premium, flexible sealant designed to withstand Upland's heat. Proper re-flashing is key to directing water away from vulnerable roof intersections and into the gutters.
