Commercial Roofing: Four Types By Material, And What They Provide

Commercial roofing is pretty straightforward. There are three main types of materials and each type has its own valuable features. If you are looking to replace the roof on a commercial development project, consider each of the following commercial roofing materials carefully. 

Flat Roof with Waterproofing Membrane

​A flat roof is typically manufactured board with a thin layer of concrete and covered with a rubbery waterproofing membrane. It is the most basic roofing you can put on a commercial building. It will prevent leaks, water damage, and provide full coverage of the building beneath it. It is also the cheapest option in terms of roofing.

​Flat Roof with Gravel Drainage

​This type of roof involves gravel that is sloped toward drainage holes. As rain passes through the nooks and crannies of the gravel, it channels downward through the carefully sloped gravel and into a drain hole. The drain hole channels the water to a downspout, which heads all the way to the ground. The benefit here is that water is constantly moved by gravity downward, making it less possible for water to pool on the roof and damage it over time. The actual roof underneath this roofing system is usually layered with asphalt for added protection.

Sloped Metal Roof

​A sloped metal roof is what a lot of people are accustomed to seeing when they look at a commercial building. With the newer metal roofing materials, the new commercial roofs do not have to look quite so industrial. You can change things up a bit while still investing in a long-lasting metal roof. The best part is that because the roof is sloped, no additional care or materials are required to keep water off of the roof. Most metal roofs are pricey, but they do include a very lengthy to lifetime warranty on all materials and construction. 

​Glass

​Architectural roofing glass is quickly becoming a very popular choice in roofing. It provides a prettier roof to any commercial building, plus it allows a lot of natural light into the building. You will need an architect to design the roof first, but then the roofing contractor you hire can take over from there. Because most of the roof is framed glass, it will be your most expensive option. Costs of installation play a major role in the price of this particular roofing material, as does the complexity of the roof design.
