Bayshore Roof Replacement: A Coastal Home Transformed
This roofing project in Bayshore began when the homeowners contacted us about algae staining and weather-related wear on their aging roof. They wanted not only a durable solution but also a visually striking upgrade. As a certified Long Island roofing contractor, we recommended GAF Slateline® Asphalt Shingles — a cost-effective, slate-look option that’s ideal for coastal climates.
The chosen color, Antique Slate, complemented the home’s traditional architecture and brought out its charm while delivering a bold, sophisticated look.
Why We Recommend GAF Slateline® Shingles
At GNP, we trust GAF roofing products for their performance and style. Slateline® Asphalt Shingles are specially engineered to mimic the rich appearance of natural slate without the weight or expense. Featuring deep shadow lines and tapered cut-outs, they create dramatic curb appeal that enhances any home.
Even better, Slateline® shingles now come with GAF Time-Release Algae-Fighting Technology, providing 25 years of protection from blue-green algae discoloration. This cutting-edge feature is backed by a StainGuard Plus™ Algae Protection Limited Warranty, giving homeowners peace of mind for decades.
It’s no surprise that this product has earned the prestigious Good Housekeeping Seal, a mark of trust and performance recognized by millions of homeowners.
