Roof Membrane Shrinkage

What is roof shrinkage.

Roof membrane shrinkage.

This membrane protects your roof from extreme temperatures and weather and even from the damage from objects that could potentially puncture your roof. As mentioned earlier incorrect application of the roof membrane is one of the causes of premature epdm shrinkage. Membrane shrinkage can also cause visible damage to the roof surface. Your membrane is what protects your roof from hot and cold temperatures as well as from extreme weather.

Generally the membrane composition and properties were found to not change sufficiently to cause excessive shrinkage. Roof shrinkage refers to the shrinking of the membrane of your roof. Otherwise it is all to easy to fall victim to problems caused by incorrect installation such as shrinkage for example. While epdm roofs are easy to install the installation must be carried out by someone who is trained and experienced in installing epdm roofing.

Roof shrinkage commonly occurs on roofs with synthetic rubber membranes such as epdm. Laminating any material introduces weak points that can cause the material to shrink crack craze and deteriorate over time. This includes cracks crazing splitting and ridging of shingles. Several factors can hasten epdm shrinkage including incorrect application poor manufacturing and faulty roof design.

In some instances shrinkage can also damage wall masonry. As the membrane shrinks it can begin to pull away from the flashing thus creating openings for leaks. This is due in part to the fact that the top layer of the material is laminated. Rather it refers to the shrinkage of the membrane that coats your roofing materials.

This coats the roofing materials and provides something of a protective layer for the roofing materials.

What is roof shrinkage. A few decades ago unreinforced rubber roof systems were plagued by shrinkage problems but thanks to technological advancements and improvements to epdm roofs the problems have diminished. How can it be avoided. Its causes include aging of the material poor installation and uv exposure.

Epdm roof membrane shrinkage. Shrinkage is most common on epdm or modified bitumen roofs. All insulation stops and. Roof shrinkage affects roofs that rely on synthetic rubber membranes most commonly ethylene propylene diene monomer epdm.

Although epdm is one of the sturdiest rubber membranes that you can use it s still prone to shrinking over time. Damage to the roof s surface. Epdm is a relatively sturdy rubber membrane and is often used to seal vehicles windows and you guessed it roofs.
