If your business needs a new roof, you have many options to choose from. If you have already decided that you want a flat roof, you should choose EPDM materials. EPDM is a synthetic rubber made of ethylene and propylene. These materials are also often used for window and door seals. EPDM is generally black but also available in white, and has a smooth surface similar to slate. It does not contain any granules like you see with many shingles, such as asphalt shingles. Below is some information about EPDM flat roofs so you can decide if it is right for your business.
EPDM Flat Roof Advantages
There are many advantages of choosing an EPDM flat roof including:
- An EPDM flat roof is less expensive and will cost approximately $0.50 to $1.50 per square foot, depending on the color and the thickness.
- Because a flat roof is flat, you can use it for extra space; for example, you can put your HVAC system on your roof to save ground cover.
- The roof will not shatter or become brittle during extremely low temperatures
- This flat roof is resistant to ultraviolet (UV) light and hail damage and will not deteriorate.
Installing EPDM Flat Roof
When the contractor installs your EPDM flat roof, they will not have to use high heat that is used when installing other types of roofing material. Instead, the contractor uses a cold adhesive. In most cases, the EPDM will be a rubber sheeting that is rolled out onto the roof.
A more advanced type of EPDM includes a polyester fleece layer that is attached to the back of the rubber. This is needed if the flat roof is being installed on top of the existing roof, because, due to the extra layer, any imperfections will flatten to provide a smooth surface.
When choosing the EPDM rubber, there are varying widths and lengths. The thicker the EPDM materials, the more resistant it will be to things like hail damage, flying debris from a storm, or a branch falling on the roof. Thicker is generally more expensive, however, so you have to take this into consideration. If there are no trees close to your building and you have very few hail storms, you may want to consider a thinner material, as all thicknesses offer protection.
