According to the Athena Sustainable Materials Institute, every year about 6 to 9 million tons of asphalt based roofing material is discarded in the US, this usually goes to the land fill sites, in Canada about 1.25 million tons of asphalt based roofing material is discarded. Metal roofs are environment friendly, as they are made from 100% recyclable materials.

A layer of zinc or aluminum is coated on the steel and then bonded. Desired paint is then applied this makes the metal roofs rust proof. Metal roofs reflect the heat in summer and insulate the interior in winter, efficiently reducing energy bills. Utilizing the dead space between the roof deck and metal also increases energy efficiency. Metal roof is an important component in green buildings, given the fact that almost $40 billion are spent annually on keeping buildings cool in the US.

Reputed metal roof manufacturers spend thousands of dollars testing their products in Miami-Dade County also known as HVHZ (high velocity hurricane zone). This area is subjected to the strongest winds in the entire country.

Many believe that metal roofing is noisy, but metal roofing installed on solid sheathing will actually keep all the noise due to bad weather out. There are metal roofs to match all types of styles, colors, and finish and last 2 to 3 times longer than conventional roofs.
