Are metal roofs energy-efficient?
A. Yes. Fiberglass blankets are the most common insulation material in standing seam metal re-roofing projects. On some projects, unfaced fiberglass insulation is simply laid directly on the existing roof surface before insulation blankets of the new standing seam roof. For other projects, insulation blankets are installed directly under the metal panels and stretched over supporting members. Foam insulation blocks are often used to separate the panels from the purlins to prevent thermal short-circuiting and condensation from forming. The roof expands and contracts independent of the insulation, giving the roof surface a floating action.

Standing steam metal roofs pay for themselves from the day that they are installed. And, they are cost-competitive. Twenty-year material warranties are customary for metal roofing systems, which is considerably longer than the standard protection for built-up and single-ply systems. Long-term warranties are so
