Standing seam metal roof:
Has panels with an attachment flange hidden by the next panel are growing in popularity throughout the low-country and the beaches of South Carolina. The fact that the attachment point is covered by the adjacent panel makes for a very clean looking installation and protects against weather.These panels can be steel, aluminum, copper, or zinc metal. However, don't be mislead: One of the biggest misconceptions about metal roofs is that they are "better" than shingle. Depends which roofing contractor you ask. Metal most definitely lasts longer, but like its shingle counterpart only has a 130 mph wind rating as does shingle, and unlike shingles if there is hail storm you will likely see small dents all over the roof that look like a golf ball. However standing seam, and 5 V metal roofs costs about 3 times as much as shingled roofs.
5 V Metal Roof or Tru-fastened:
Thru-fastened panels are long-length panels that have ribs running from the eave to the ridge of the roof. These panels are fastened with visible gasketed screws that penetrate the panel into the roof decking substrate and underlayment. Also known as 5 V crimp, this type of roofing which is used extensively in the Southeastern U.S. can be slightly lower in cost than a standing seam metal roof.
Be Green with Metal:
Conventional roofing products, including asphalt shingles, contribute an estimated 20 billion pounds of waste to U.S. landfills annually, whereas metal roofs can often be installed over an existing roof, eliminating the cost and eco-impact of tear-off and disposal.
