John Goess Roofing | Roofing Services in Westbury, NY 11590

Our process is built on transparency and local trust. We start with a free, detailed estimate and can provide addresses of recently completed projects in Westbury so you can see shingle colors and our work firsthand. As a GAF Master Elite and Owens Corning Preferred Pride contractor, we use quality materials backed by strong warranties. Every installation includes our five-year workmanship guarantee and we ensure your property is left clean and tidy, a standard we've maintained since 1975.

In Westbury's climate, flashing is a critical detail we inspect thoroughly on every job. For replacements, we install new, corrosion-resistant flashing integrated with the underlayment and shingles to create a watertight seal. For repairs, we assess the extent of separation or corrosion and either reseal and secure the existing flashing or recommend a full replacement if integrity is compromised. Proper flashing is key to preventing leaks, and our workmanship guarantee covers this essential component.

We offer two layers of protection. First, through our certifications, we can provide enhanced manufacturer warranties like the GAF Systems Plus or Golden Pledge warranty for their shingles. Second, and just as important, is our own five-year workmanship guarantee, which covers the installation itself. This dual coverage ensures your investment in a new roof is protected against both material defects and installation quality for years to come.
