A: It depends on how close to the water you are and how much wind exposure the roof gets. Standing seam metal handles salt air and high wind better than almost anything else, which is why it shows up so often on waterfront and bayfront properties. GAF architectural shingles, installed as a full system rather than just nailed down, perform well further inland and cost less upfront. We install both, and we’ll tell you honestly which one fits your specific property.
