Cortez Roofing & Construction | Roofing Services in West Covina, CA 91723

A professional roof inspection is your first defense against roof deck rot, a common issue in our area. We meticulously check for signs of trapped moisture, compromised shingles, and poor ventilation—all precursors to rot. Catching these problems early allows for targeted repairs, like fixing a small leak or improving attic airflow, which can prevent expensive structural damage to the decking beneath your shingles.

Damp insulation often points to a persistent leak or condensation issue, common in West Covina homes. It doesn't always mean a full replacement is needed. We start with a thorough inspection to locate the moisture source. Often, a precise roof repair or addressing ventilation solves the problem. However, if the leak has caused widespread deck rot or the roof is near the end of its lifespan, a roof replacement or reroofing might be the most cost-effective, long-term solution to protect your home.

If not installed correctly, yes. Improper skylight installation is a frequent cause of leaks. Our team specializes in watertight installations that integrate seamlessly with your roofing system. We use proper flashing techniques and ensure the surrounding roof structure is sound to prevent moisture intrusion. For existing skylights, our repair service fixes common failure points like sealant cracks or flashing damage, which are often the culprits behind insulation moisture and deck rot near the skylight.
