Everything You Should Know About Roof Shrinkage

If you plan on installing an ethylene propylene diene monomer (EPDM) membrane or modified bitumen roof on your commercial building, it’s important to understand roof shrinkage.What Is Roof Shrinkage?

Roof shrinkage naturally occurs over time to EPDM and modified bitumen roofs. That’s why commercial roofers design roofing systems to take shrinkage into account. However, mistakes during roof design or installation can cause premature shrinkage and lead to other problems. When a shrinking membrane pulls at the flashing at curbs, walls and penetrations, splits and cracks can form, making the roof more vulnerable to leaks.

How to Deal With Roof Shrinkage

The best way to deal with roof shrinkage problems is to prevent them. You can do this by hiring an expert in commercial roof and gutter installation. You can also prevent these problems by scheduling regular roof maintenance.

Our crew at Kidd-Luukko Corporation knows how to design for shrinkage and to spot the signs of roof shrinkage problems. We’re well-versed not just in new roof installation, but also in troubleshooting issues with existing commercial roofs. Our roof shrinkage solution involves a comprehensive roof inspection and replacing any affected flashing and curbs. Pressure from pulling is relieved by cutting the flashing and then securing the field sheet with a russ strip or termination bar. New flashing is then installed to ensure that your roof stays leak-free.
