Roofing Services Fresno CA | Call Montero Roofing

In Fresno, roof deck rot is often caused by trapped moisture from leaks or poor attic ventilation, especially during our hot summers. We start by locating and repairing the source of the moisture intrusion. Then, we carefully remove and replace the damaged decking sections with new, treated plywood to ensure a solid foundation for your roofing materials, preventing further structural issues.

Roof valleys are critical drainage channels, and in Fresno, they can fail due to seasonal debris buildup, aging sealant, or incorrect installation. Our process involves a detailed inspection of the valley flashing and surrounding shingles. We then clean the area, replace any compromised flashing with high-quality materials, and re-seal it to create a watertight channel, effectively directing rainwater away from your home.

Act immediately. Even a small leak can lead to significant roof deck rot, mold growth, and interior ceiling damage surprisingly fast, especially with our climate. We recommend calling for an inspection as soon as you notice water stains, damp spots, or missing granules. A prompt, professional assessment from our team can prevent a minor repair from turning into a major, costly project.
