Types of Commercial Roofing

Commercial Roofing Services

Metal Roofing

Metal roofing is a great looking roof and is very easy to clean and maintain. Metal holds up the longest in any climate and offers some of the longest warranties. Metal roofing works best with solar panels as it allows for panels clips to be installed instead of holes be poked in the roofing.
