As the owner of a commercial building, the functioning structural components are going to be a little different than your typical residential structure. One specific example of what can be completely different is the roof of your building. Many commercial buildings are large in size, which means the average steepled or sloped roof would not make much sense. Most commercial buildings have more of a flat rooftop or a rooftop that is only slightly sloped. Having a flat roof means that roofing materials will be different for sure. Here is a look at some of the most common types of flat roof materials.
PVC Membrane Roofing
PVC membrane roofing is actually a roofing system that consists of an underlying membrane that acts as a protective layer and an upper layer of PVC that thwarts moisture and UV rays. The PVC membrane roofing system is a little more time-consuming to have installed because all underlying roofing materials that are already in place must be taken off, and the installation involves a two-step process that takes a while to complete.
Rubber roofing is resilient and long-lasting, which are two key attributes to look for in a commercial roofing material. The rubber roofing usually comes in large sheets that are rolled up and hoisted up to the top of the building. Each sheet is then unrolled and set in place with a sealant and then the seams between the rubber membrane sheets are sealed together with a rubber welding tool. This welded installation process ensures the roof is completely sealed off from moisture.
Silicon Spray-On Roofing
Silicon spray-on roofing is not quite as common on commercial buildings as rubber roofing or PVC membrane; however, the silicon option is still pretty popular. Silicon spray-on roofing is preferable among business owners because it can be installed over existing roofing materials instead of having to remove whatever is already in place. The contractor protects all roofing elements, such as ventilation pipes and HVAC components, with a plastic barrier before the spraying part of the installation begins. Silicon spray-on roofing has a really good ability to stand up to years of use because the application is extremely resilient to water even on a flat surface where pooling can be an issue.
