The Metal Roof - an energy efficient alternative to traditional asphalt roofing
Metal roofs absorb 34% less heat than traditional asphalt shingles, according to a 1985 Florida Solar Energy Center study. This can translate into significant energy savings.
Most metal roofs reflect away more of the sun’s heat than do asphalt shingle roofs. This keeps the roofing materials cooler so less heat is radiated down through the ceilings to the living area. Also, the underside of the metal surface has lower emissivity than shingles, so even less heat radiates down to the ceiling below.
The final energy advantage is the metal is relatively thin and has a contour stamped into it to simulate other styles of shingles. This contour creates an air gap between most of the roofing and the roof sheathing below it. With a sloped roof, outdoor air naturally circulates up under the metal roof to keep it cooler.

A metal roof may cost more initially but pays back in the long run even without the tax credit ( Metal roofs qualify for a $500 energy tax credit - use IRS form 5695).
Other benefits of a metal roof:
- long life / durability
- low maintenance
- fire retardant
- green benefit: can contain recycled material
- green benefit: can be installed over existing an existing roof, eliminating the need for your existing roof to go to a landfill
