Can a Retrofit roof work with Energy Star and LEED requirements?
Yes. Leaky flat non-metallic roofs can be replaced with sloped metal roofs by adding an engineered light weight secondary structural system to the existing building. Metal roofing is an excellent choice for steep slope retrofit roofing projects. There are a number of retrofit options available to cover asphalt shingles, modified bitumen or BUR eliminating the need to landfill old roofing materials. Then, you receive all the advantages of the new metal roof.
