The roof of any commercial or industrial building is a complex structure, and you must choose a roofing company with experience in commercial roofing. Commercial roofs are often built with different materials than the ones used in residential roofing projects. Instead of sloped roofs, for instance, many commercial or industrial buildings have flat roofs. This can lead to a lower life expectancy for the roof, and a greater risk of leaks. This is why it's important to get your roof replaced by a professional commercial roofing company. Hepler Contracting LLC has years of experience installing new commercial roofs in the Greater Pittsburgh area.
