Special considerations with commercial roofs


Isn’t a roof a roof? Not exactly.

Generally speaking, there are a few key differences between residential and commercial roofing projects. The main difference between commercial and residential projects is often the size of the building that the roof must cover. This, combined with the fact that commercial roofs are more likely than residential roofs to be flat or low-sloped, means they tend to be susceptible to different stress loads. For this reason, it is particularly important to have your commercial roof inspected regularly with a regular maintenance program.

Roy Dennis Roofing is one of only a handful of contractors authorized to install Soprema Alsans RS.

PMMA has become the go to solution for those hard to solve waterproofing problems.
