A metal roof is the last roof you'll ever need. Standing seam metal lasts 40-60 years with virtually zero maintenance. It reflects solar heat, sheds hail and debris better than asphalt, and handles NH wind speeds that would rip shingles off. Alton Bay Roofing & Maintenance installs residential and commercial metal roofing throughout Alton Bay.

About Our Alton Bay Metal Roofing Services
We install 24-gauge and 26-gauge steel panels in Galvalume and pre-painted finishes. Kynar 500 PVDF fluoropolymer coating is the gold standard. It resists fading, chalking, and color shift for 40+ years. Sheffield Metals and McElroy Metal are our primary suppliers, both with proven track records.
Metal roofing works on pitches as low as 3:12 for standing seam. Steeper pitches look incredible in metal and shed water faster. For low-slope applications, we use specific underlayment and sealant details to ensure watertight performance. We help you select the right panel profile for your roof geometry.
