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. Grantham Roofing & Maintenance installs residential and commercial metal roofing throughout Grantham.
Our Metal Roofing Process
Design & Material Selection
We discuss your goals, show you panel and color samples, and help you choose the right metal system for your Grantham home. Standing seam, corrugated, or metal shingle. Each has different aesthetics, costs, and performance characteristics.
Panel Ordering & Prep
Your panels, clips, trim, and flashing fabricated to spec. Materials staged at your Grantham property the day before installation. Everything verified against the project scope before install day.
Precision Installation
Standing seam panels installed with Z-clips on solid substrate or battens. Each panel locked into the adjacent panel with a mechanical seamer. No exposed fasteners, no maintenance points. Trim and flashing hand-formed for a custom fit.
Warranty & Completion
We walk the property with you and point out the finished details. Manufacturer warranty and workmanship warranty provided in writing. Your metal roof is covered for decades.

Why Choose Grantham Roofing & Maintenance for Metal Roofing?
40-60 Year Lifespan
Standing seam metal is the longest-lasting residential roofing material. Install it once and never replace it again. The math works out better than replacing shingles twice.
Class 4 Impact Resistance
UL 2218 Class 4 rated. Handles the largest hail without compromising the waterproof system. Often qualifies for insurance premium discounts in NH.
Kynar PVDF Finish
40-year color warranty on Kynar 500 PVDF coatings. No fading, no chalking, no color shift. Your metal roof looks the same in 20 years as it does on install day.
Energy Savings
Reflective metal reduces cooling costs 15-25%. In NH heat, that adds up fast. Metal pays for itself over its lifetime in energy savings alone.
