EPDM (ethylene propylene diene monomer (M-class) rubber) has properties that give it outstanding heat, ozone and weather resistance. One of its benefits it that is does not pollute the run-off rainwater. When EPDM is installed correctly as a covering to waterproof roofs, you can expect your roof to keep you warm and dry for 20 years

 

Seam separation is commonly caused due to lack of proper seam tape and the use of improper materials to achive the correct bond needed to last the life of the roof.
