A Closer Look at Commercial Roofing Materials
According to a market survey conducted by the National Roofing Contractors Association (NRCA) from 2015 to 2016, thermoplastic polyolefins, or TPO, is the most popular choice of material for commercial roofing, taking about 40% of the market share in new roof constructions and 30% for roof replacement. This is followed by ethylene propylene diene monomer (EPDM), making up 22% of all brand new roofs and 26% of replacements. Modified bitumen, or Mod-bit asphalt roofs, comprises 12.4% of new roofs, and 14% of replacements, takes up third place. The remaining quarter of the market is shared between all other types of commercial roofing including metals, liquid-applied membranes, PVC and others.
While there are pros and cons for all roofing types, it’s clear from the survey that these three materials greatly outmatch the rest. Why is this so? John Peters Roofing discusses below.
Modified Bitumen Roofing
Asphalt has been used as a roofing material in North America for over 100 years. Asphalt, sometimes known as bitumen, is a black tar-like material derived from petroleum. Modified bitumen makes use of this historically stable type of roofing and enhances it with a few additives to increase its durability, versatility, and overall stability.
Mod-bit roofing is relatively affordable and can be easily installed through a variety of means. The most common application is through hot mopping that involves “mopping” the base sheet with the soft heated bitumen spread.
As far as installation goes, EPDM roofs are possibly the easiest of all roof types to install. These synthetic rubber sheets can be fully adhered or ballasted with liquid adhesives at the seams, creating a perfectly sealed barrier. Perhaps the biggest draw of EPDM roofs, however, is its resistance to the harsh effects of ultraviolet and chemical damage, making it the perfect roofing choice for many commercial and industrial buildings.
If you were using a search engine to look for good providers of roofing near you it’s a good idea to look for a company that offers TPO roofing. TPO has been around since the 1990s, and it has proven to be a viable alternative to PVC when it comes to thermoplastic membranes. One of the most attractive advantages of this particular roofing type is its energy efficiency. Compared to other materials, TPO roofing offers great returns on investment from the savings you get from air conditioning costs.
