Have you heard of metal roofs?

About one-third of new homes built today come with metal roofs, according to the National Roofing Contractors Association, and an increasing number of homeowners are choosing metal for replacement roofs. Some of the advantages are they last about twice as long as traditional asphalt shingles. They can withstand high winds. When treated with coatings and finishes, they reflect heat to keep your house cool and air conditioning bills down. There are few drawbacks. They are slippery, so it can be difficult to find people to work on them. Rain and hail sound loud. And they cost about twice as much as even the most expensive fiberglass-asphalt shingles.
