The roof on your commercial building is its first and most important line of defense against the elements. If it has been damaged or is starting to age into a state of disrepair, then your building is vulnerable to extensive damage that will not only be costly to repair, but might also interfere with your business operations for days or weeks. Fortunately, you can call the commercial roofing experts at DeFrehn Roofing for a free inspection and estimate. Based in Newtown, Pennsylvania, we are a family-owned and -operated commercial roofing company that has served local businesses with quality and integrity since 1974.
