Common Types Of Commercial EPDM Roofing Damage

by Vanessa Lord

If you have an EPDM roof on your commercial or business building, then you should inspect the membrane material often for signs of wear, tear, and damage. There are a few types of common issues that you will see, so keep reading to learn what they are, why they happen, and how they are repaired.

Seam Tears

You are likely to see your EPDM roof pulling apart at the seams over the course of five years or more after installation. This is a normal occurrence that is likely to appear due to an issue called shrinkage. Shrinkage is exactly what it sounds like, the membrane material will actually shrink over time and this can occur to the point that several feet of material has shrunk or pulled away from the roof. 

Typically, shrinkage will show up at the seams and you may see all of the seams pulling apart several inches or you may see on seam or edge that has a foot or larger gap. Fortunately, the shrinkage is due to thermal heat damage and the reduced elasticity of the membrane. It does not mean that the membrane is damaged. This means that a new piece of membrane can be slipped into the spot where the gap or gaps have developed. A roofing contractor can do this and they may also loosen portions of the membrane to prevent future tears and shrinkage issues.

Keep in mind that certain seam issues may be present with curled edges. If this is the case, then the roofing professional may need to cut away a portion of the seam edge to prevent adhesion issues when new cement is secured.

Chemical Damage

EPDM is a type of synthetic rubber material that is made from elastomeric compounds. And, like other types of rubber materials, the roofing material is prone to damage from certain types of chemical agents. Oil or petroleum-based fluids are most likely to damage the material and this can leave holes and openings in your roof. This can lead to openings that cause leaks.

Solvents and other types of chemicals can also cause damage and eat through your membrane roof. And, you can often see the remnants of chemical damage as discoloration of the membrane. 

Discolored sections of the roof will be identified and they may be probed to see if they have been damaged structurally. If there is a hole or a risk of one, then the damaged section will be removed and replaced. In this situation, the roofer may also try to identify where the chemical came from so future damage can be avoided.
