Interline Custom Roofing | Roofing Services in Harlingen, TX 78550

Given Harlingen's humid, coastal climate, flashing corrosion is a frequent issue that can lead to leaks. We conduct a detailed inspection of all flashing points, remove any corroded material, and replace it with high-grade, corrosion-resistant metals like aluminum or galvanized steel, properly sealed to withstand our local weather conditions and prevent future water intrusion.

When we discover roof decking rot—often from hidden leaks or storm damage—we prioritize structural integrity. We carefully remove the affected shingles, cut out and replace all compromised decking sections with new, treated plywood, and ensure proper ventilation is restored. This foundational repair is crucial to prevent sagging, mold, and ensuring your new roof overlay or replacement has a solid base.

We provide a transparent, expert assessment based on the extent of damage, the age of your roof, and your long-term goals. For localized issues like isolated flashing or decking problems, a targeted repair is often the most cost-effective solution. If damage is widespread or the roof is near the end of its lifespan, we'll explain why a replacement offers better protection and value for your Harlingen home, providing clear options without pressure.
