Roof Membrane Shrinkage

Roof shrinkage affects roofs that rely on synthetic rubber membranes most commonly ethylene propylene diene monomer epdm.

Roof membrane shrinkage.

These roofing membranes shrink absorbs heat and the adhesives fail due to ultraviolet rays. Although epdm is one of the sturdiest rubber membranes that you can use it s still prone to shrinking over time. Roof shrinkage commonly occurs on roofs with synthetic rubber membranes such as epdm. Epdm roof membrane shrinkage while epdm roofs are easy to install the installation must be carried out by someone who is trained and experienced in installing epdm roofing.

Generally the membrane composition and properties were found to not change sufficiently to cause excessive shrinkage. Epdm membrane roof is black and thin. Several factors can hasten epdm shrinkage including incorrect application poor manufacturing and faulty roof design. What is roof shrinkage.

In some instances shrinkage can also damage wall masonry. Membrane shrinkage can also cause visible damage to the roof surface. This includes cracks crazing splitting and ridging of shingles. What is roof shrinkage.

The paper presents conclusions and recommendations for existing roofs. Ethylene propylene diene monomer also known as epdm is a synthetic rubber with an elastic nature and is the same type of rubber used to make inner tubes of tires. Otherwise it is all to easy to fall victim to problems caused by incorrect installation such as shrinkage for example.
