What is an EPDM roof?
Ethylene propylene diene monomer, more commonly referred to as EPDM, is an extremely durable synthetic rubber roofing membrane that is commonly used worldwide. EPDM is available in both black and white, and can be enhanced with commercial roof coatings. It is sold in varying widths and thicknesses. Its superior durability and cost-effectiveness are the reason EPDM is one of the most popular flat roof systems installed in the U.S. today.
What are Commercial Roofing Systems?
There are many reasons why a vast majority of commercial buildings have flat roofs:
- Flat roofs require less material than a sloped roof due to the smaller square footage
- They are easier and quicker to install
- They are easier to maintain as they are safer to walk on in all seasons
- They are generally easier to repair
- Air conditioners can be installed on flat roofs, freeing up ground space
All these characteristics add up to a less expensive total cost of ownership of flat roofs for larger commercial buildings. The primary concern of a flat roof is drainage. Standing water can lead to a breakdown of roofing materials, therefore regular inspections and maintenance are highly encouraged – particularly in wet or snowy climates.
How do you maintain an EPDM roof?
EPDM roofs have fewer seams due to the availability of wide rolls of the material. Regular inspection and maintenance of an EPDM roof would include inspecting the seams, edges and flashing for signs of shrinkage, cracks, or long-standing water. EPDM roof repairs are generally quick and easy if caught early. Minor repairs might involve sealants, where larger repairs might require a patch. Proper surface preparation is key to ensuring the repairs last, and for this reason, you’ll want to make sure you have reputable commercial roofing contractor like Prime Roofing. In Colorado, inspections should be done in the late spring and early fall.
Is EPDM hail resistant?
EPDM roofing systems have been successfully tested to 3″ hailstones. A qualified commercial roofing installer can employ techniques to increase a flat roof’s ability to sustain severe hail storms such as commonly seen in Colorado. If you are considering a new EPDM roof, talk to the roofing experts at Prime Roofing for the highest quality EPDM installation to stand up to Colorado’s frequent and severe hail storms.
How long should an EPDM roof last?
When professionally installed and maintained, an EPDM roof should last approximately 40-50 years. In a study by the EPDM Roofing Association, 5 roofs between 28 and 32 years old were analyzed and assessed to be performing “like new.”
