Navarro Roofing | Emergency Roof Repair in San Antonio, TX

The most frequent repair we perform is fixing damaged or failed roof flashing. In our climate, the constant expansion and contraction from heat, combined with heavy rain, can quickly compromise flashing around chimneys, vents, and valleys. This is a critical repair, as failing flashing is a leading cause of leaks and the subsequent roof decking rot we see in local attics. Addressing it promptly protects the structural integrity of your entire roof.

While repairs can fix isolated issues like a few bad shingles or flashing, a replacement is often necessary when we find widespread decking rot, multiple persistent leaks, or damage across over 30% of the roof. Given our local issues with moisture and heat degradation, if your roof is near or past its expected lifespan (typically 15-25 years for asphalt shingles in Texas) and showing these signs, a full replacement with modern, durable materials is the most reliable long-term solution to prevent ongoing problems.

Prevention starts with a thorough inspection. We first remove all old materials and meticulously inspect the wooden decking for any existing rot, replacing every compromised section. Then, we install a high-quality synthetic underlayment that provides a superior moisture barrier compared to traditional felt. This is crucial for our humid climate and heavy rains. Proper attic ventilation is also a key part of our installation plan to reduce heat and moisture buildup, which are the primary causes of decking rot.
