McNiel Roofing & Sheet Metal - San Antonio's Reliable Roofing Repair

In San Antonio, roof valley leaks are often caused by debris buildup (like leaves and branches) that traps water, or by worn-out underlayment and sealant from our intense sun and heavy rains. Our fix starts with a thorough cleaning and inspection. We then replace any compromised materials with high-quality, UV-resistant underlayment and apply proper sealants to ensure a watertight channel, preventing future leaks during our frequent storms.

The combination of high heat, humidity, and occasional hail in our area accelerates the corrosion of standard metal flashing. We address this by using and installing corrosion-resistant materials like galvanized steel or aluminum. Our expert sheet metal team can fabricate and install custom flashing that fits perfectly, providing a durable seal around chimneys, vents, and skylights to stop leaks at their source.

We know a sudden leak needs immediate attention. Our team offers prompt emergency response for San Antonio homeowners. We'll quickly deploy a crew to perform a temporary tarping or sealing to prevent interior damage, then schedule a permanent, expert repair at your earliest convenience. Our goal is to secure your home fast and provide a lasting solution tailored to our local weather patterns.
