Richardson & Son Roofing | Roofing Services in Duncanville, TX 75116

A recurring valley leak often points to underlying underlayment failure or improper flashing. Our most effective repair involves a thorough inspection to remove compromised materials, installing a new, high-grade ice and water shield underlayment in the valley, and sealing it with precision metal flashing. This method addresses the root cause, not just the symptom, providing a durable solution suited for our local climate.

Signs of underlayment damage inside your home can include water stains on ceilings or walls, especially after rain, or a musty smell in the attic. From the outside, you might see curling or missing shingles. This repair is critical because the underlayment is your roof's secondary water barrier. In Duncanville, where sudden storms are common, a compromised underlayment can lead to rapid water intrusion, risking structural rot and mold.

It depends on the extent of the damage and the age of your roof. For localized underlayment damage on a relatively new roof, a targeted repair is often sufficient. However, if the underlayment is failing in multiple areas or your shingles are over 15-20 years old, a full replacement is usually more cost-effective and reliable. We provide honest assessments to help you make the best long-term investment for your home.
