Just Say NO To Acrylic!
We are seeing many of these types of failures within 3 years of installation. The video below and the photo to the right are asphaltic bentonite clay emulsion roofs with an acrylic coating topcoat. This is what happens when water ponds on these types
of roofing systems.
The acrylic top coat is not waterproof so water and moisture penetrated the acrylic roof coating causing it to fail, exposing the emulsion. After time, the UV rays and heat breaks down the bentonite clay emulsion. This is the “waterproofing” in an emulsion acrylic roof system. The oils are baked out in a short period of time and the emulsion deteriorates. Once the emulsion has begun to deteriorate, leaks begin. Left unprotected the emulsion roof will lose all of its waterproofing ability in a short period of time, leaving behind a dirt roof (see photo to the right). A SureCoat Roof System is exceedingly UV stable therefore, ponding water does not affect its waterproofing ability and heat and UV has little effect on the Solar Reflective Index (SRI) of a SureCoat roof.
Acrylic and Emulsion Roof Video
This is an 88,000 SF BUR with a failing emulsion and acrylic system that was installed just a few years ago. This is what happens when water ponds on these types of roofing systems. Watch the You Tube Video:
