Roof shrinkage is a common problem that can occur with certain types of roofing materials, such as single-ply membranes like EPDM (ethylene propylene diene monomer). This problem is characterized by the shrinking of the roofing material, which can result in cracks, wrinkles, and other forms of damage. This type of damage can create a need for repairs and even the replacement of the entire roof. Continue reading to learn more. 

What Causes Roof Shrinkage?

Here are some potential causes of roof shrinkage along with some ways to deal with them:

Age

Over time, roofing materials can naturally shrink and deteriorate, particularly if they are exposed to harsh weather conditions. Environmental conditions like heat and extreme cold can accelerate the deterioration. Regular maintenance and inspections can help detect signs of shrinkage early and prevent further damage. If the roof is old and experiencing extensive shrinkage, replacement may be necessary.

Installation Errors

Incorrect installation of roofing materials can cause shrinkage to occur, particularly if the material is not installed properly or if the adhesive used is not compatible with the roofing material. If the shrinkage is due to an installation error, it's important to have the roof inspected by a professional to identify the cause of the problem. The roofing material may need to be re-installed or replaced.

Exposure to Extreme Temperatures

Rapid changes in temperature can cause roofing materials to expand and contract, which can lead to shrinkage over time. Some climates are more prone to this type of temperature fluctuation. It is important to choose roofing materials that are suitable for the climate and to ensure proper ventilation to reduce temperature fluctuations. Regular inspections can help identify any signs of shrinkage early.

Poor Quality Materials

Inferior quality roofing materials may be more prone to shrinkage and damage. It is important to use high-quality roofing materials that are designed to withstand the elements and to work with reputable roofing contractors who have experience installing and maintaining the materials.

If you suspect that your roof is experiencing shrinkage, it's important to have it inspected by a professional to identify the cause of the problem and determine the appropriate course of action. Ignoring roof shrinkage can lead to further damage and costly repairs, so it's important to address the problem as soon as possible. A leaking roof can permanently damage the underlying structure.
