Mt. Vernon Roofing Contractor | Commercial & Residential Services Since 1971

Yes, roof valley leaks are a frequent concern for Mt. Vernon homes, often caused by wear, debris buildup, or improper flashing. At A To Z Roofing, we address this by first conducting a thorough inspection to find the source. Our repair typically involves removing old, damaged materials, installing new high-quality ice and water shield underlayment for superior protection, and expertly re-flashing the valley with manufacturer-approved materials. As an approved GAF applicator, we ensure the repair integrates seamlessly with your existing roof and is backed by a strong warranty.

Our preventative maintenance program is designed to extend the life of your flat roof, which is crucial for Westchester County's variable weather. We perform bi-annual inspections to identify and address minor issues like small punctures, seam separations, or drainage problems before they become major leaks. This proactive care helps maintain the integrity of systems like modified bitumen or EPDM, preserves your manufacturer's warranty, and can save significant money on costly emergency repairs or premature replacement.

When you choose A To Z Roofing, you get the direct oversight of our experienced owner on your job site. This means from the initial estimate and material delivery to the final inspection, a principal of our company is personally involved. This hands-on management ensures the work meets our high standards for craftsmanship, that the crew follows all manufacturer specifications for products like GAF shingles or Firestone roofing, and that any questions you have are answered promptly by someone with the authority to make decisions.
