Hot roof converted to cool roofing

With your cursor, see Before and After
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:

Final days of photos
Blister repairs on flat hot roof
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
Flat roof base work
1. Squeegee elastic roofing sealer over blister
repaired area
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.
Acrylic seaming of base work
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.
First white acrylic application
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.
Final acrylic coating
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
