What is a Roof Expansion Joint?

A roof expansion joint is a roofing membrane that is designed to seal joining roofs and walls. It is supposed to be airtight and provide a waterproofing and firestopping element to stop any leaks that may cause unnecessary wear on buildings. Many manufacturers create expansion joints, but only a few pass Sure-Seal’s standards when it comes to design and effectiveness.

The best roof expansion joint design should have longevity and practicality in mind. It should not only fill cavities on joining walls or wall to roof joints but it should also be designed to seal and protect the walls and roofs from leaks and other elements that can cause wear on a structure.

It should be designed to seal—and that is what the company is all about. Here at Sure-Seal, we only choose the best sealants, caulking, and expansion joint materials.

The Emseal Roof Expansion Joint PDF and other Emseal products are some of our go-to suppliers when executing projects. Because of its high-quality design and effectiveness—Emseal products are in line with our vision… High-quality workmanship, SAFETY, and structural integrity!
