Rio Grande Valley Roofing | Roofing Services in Harlingen, TX 78550

In Harlingen, the intense sun and thermal expansion are the main culprits for flashing separation. The metal expands and contracts, pulling away from vents, chimneys, and walls, leading to leaks. We fix this by carefully removing the compromised flashing, preparing the surface, and installing new, high-quality flashing sealed with durable, UV-resistant compounds to withstand our local climate.

Signs of underlayment damage often appear inside your home as water stains on ceilings or walls, especially after a rain. The underlayment is your roof's secondary water barrier. If it's compromised from sun degradation or past leaks, your decking is at risk of rot. We perform a detailed inspection, replace any damaged sections, and ensure proper overlap and sealing to restore this essential protective layer.

We recommend a simple visual check from the ground after major weather events. Look for lifted or bent metal around roof penetrations (flashing) and any missing or curled shingles, which can expose the underlayment. Also, check your attic for daylight coming through or any moisture. For a thorough assessment, we offer free, no-obligation inspections to catch and address these local issues before they lead to major damage.
