A house with a metal roof near you is most likely a standing seam variety. Standing seam metal roof is a special type of metal roof that lifts the seam above the level of the roof itself.
Standing seam metal roofs are a completely different product. Not only is the type of material independent of petroleum prices, but the size and shape of the material and its installation methods are different, too.
Continuous panels run from the ridge of the roof all the way down to the eaves. Between the panels are seams connected by fasteners which are raised above the level of the metal roofing.
Many homeowners have found that the higher initial cost of this type of roof will ultimately pay off due to its higher durability and reliability.
