For your business, there are probably numerous reasons why you have chosen a flat roof: they are easy to maintain and install, they are often considerably less expensive than a pitched roof, and they allow ease of access so you can install any other additions to the business that you wish, including any HVAC systems that require roof access. However, you may not know what sort of material from which you wish your flat roof to be constructed. Read on, and discover a bit about just a few of the common types of material from which your commercial building's flat roof can be constructed.
EPDM Rubber Roofs
EPDM is short for ethylene propylene diene terpolymer. EPDM is essentially a type of rubber that are highly resilient against any chemicals that might come into contact with your roof, and tends to be just as resilient against the elements. When EPDM was first developed, there were numerous reports that it can suffer from shrinkage due to overexposure to harsh weather. However, EPDM technology has made leaps and strides since that time, and, so long as the roofing is adhered and installed properly, this shouldn't be a problem, and it should be a roofing material that will serve you well for years to come.
Asphalt Built Up
The asphalt built up roof is an incredibly inexpensive option when it comes to your commercial flat roof's material. The installation process revolves around four layers of asphalt being poured and mopped onto the entirety of your roof. In between each layer a large sheet of fiberglass felt is installed, which will keep your roof well insulated, protected from the elements, and also protected from UV radiation. One of the biggest problems associated with asphalt built up roofs is the fact that they can become susceptible to cracking.
TPO Roofing Systems
TPO refers to the term thermoplastic polyolefin. A TPO roof actually looks quite similar in aesthetics to an asphalt built up roof, but the similarities tend to end right at the aesthetic level. TPO roofs are still highly resilient forms of roofing, especially if you decide on on utilizing fire and UV resistant thermoplastic polyofelin, which adds an extra dimension of protection to the roofing.
