For a hot roof as a result of a sunny, warm day, this page illustrates a flat roof maintenance system that converts the surface to a cool roof with a ten year warranty against leakage. The materials include Henry's elastic roofing sealer, fabric and Andek's x-brite white acrylic.
Instead of an expensive tearoff, this system is being applied over several previous roofs. The crew shown here has been applying this system for over two decades. Indeed the EPA has used one of our projects on their website: one of our Baltimore projects
The crew has emptied the winter-grade version of the elastic sealer from five gallon pails onto the roof. Years of experience has taught them how to space the "elephant tracks."
Blister repair is performed before the "runs" of mesh are applied. With the removal of the old delaminated roofing, elastic roofing sealer is squeegeed over the area. Then the area is reinforced with #90 fiberglass felt. Blistered area is now ready for the application of the base of the work
1. Squeegee elastic roofing sealer over blister
2. Roll mesh in a straight line, overlapping seams three inches
3. Brush mesh to embed into elastic roofing sealer
At this point, the work "looks like hell" to quote the customer, but the hardest part of the project is completed according to the crew.
The next five photos illustrate the seaming: Acrylic is brushed down under the mesh, then the top mesh is smoothed into the lower lap with acrylic. Fishmouths are forbidden.
The first top coat of white acrylic is the "white" tint from Andek Corporation. Already the seams have two layers of the acrylic. One of the crew members blows debris from nearby trees from the surface before coating. Usually the application of the acrylic starts on the flashings and other detail work.
Upper roof and front roofs were completed with the second coat. Parapets and flashing on lower roof were also done, but concern about weather stopped work
Acrylic photos of both coats are located at beginning of page.
