Roofing Services Fresno CA | Call On Top Roofing

In Fresno, signs of roof deck rot include sagging rooflines, dark stains on ceilings, and a musty odor in the attic. It's common here primarily due to poor attic ventilation. Our hot summers trap moist air, which condenses on the cooler underside of the roof deck, leading to wood rot over time. A professional inspection can assess ventilation and identify any compromised decking that needs replacement.

Ridge tile movement is frequent in Fresno due to our strong seasonal winds and the expansion/contraction cycles from the heat. Temporary fixes often fail. A permanent repair involves removing the old mortar or mastic, properly realigning the tiles, and securing them with a high-grade, flexible roofing adhesive designed to withstand our local temperature swings and wind uplift, ensuring they stay in place.

In many cases, only the affected section needs replacement. We carefully remove damaged decking, treat any surrounding areas for mold or mildew, and install new, pressure-treated plywood that matches the existing roof's strength. We then seamlessly integrate new underlayment and shingles with the old. A full replacement is only necessary if the rot is widespread or the overall roof is near the end of its lifespan.
