Roof Membrane Shrinkage

Although epdm is one of the sturdiest rubber membranes that you can use it s still prone to shrinking over time.

Roof membrane shrinkage.

As the membrane shrinks it may yank and pull at the wood blocking and gravel stop it s attached to. 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. What is roof shrinkage. Roof shrinkage affects roofs that rely on synthetic rubber membranes most commonly ethylene propylene diene monomer epdm.

Several factors can hasten epdm shrinkage including incorrect application poor manufacturing and faulty roof design. This includes cracks crazing splitting and ridging of shingles. What is roof shrinkage. Epdm is a relatively sturdy rubber membrane and is often used to seal vehicles windows and you guessed it roofs.

Roof shrinkage commonly occurs on roofs with synthetic rubber membranes such as epdm. These roofing membranes shrink absorbs heat and the adhesives fail due to ultraviolet rays. Some common reasons for shrinkage are. Generally the membrane composition and properties were found to not change sufficiently to cause excessive shrinkage.

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. Membrane shrinkage can also cause visible damage to the roof surface. In some instances shrinkage can also damage wall masonry.
