Method of waterproofing building roofs and building panels

An alternative roofing system, comprising:

• a plurality of decking panels installed over a framed structure, the panels joined at edge-to-edge seams;
• a first coat of a liquid silicone elastomeric (SE) roof coating applied along edge-to-edge seams of the decking panels and between adjoining portions of the decking panels and, if present, along boundaries with structures passing through the decking panels;
• a non-metallic flashing strip formed of anti-fracture fabric (AFF) applied exclusively to the first coat of SE roof coating covering the edge-to-edge seams of the decking panels and adjoining portions of the decking panels and structures passing through the decking panels, thereby forming a continuous cover over the seams and adjoining portions;
• a second coat of the SE roof coating applied over the decking panels and the adjoining portions including the first coat of the SE roof coating and the non-metallic flashing strips, to form a coated, waterproofed surface on the roof;
• and
• a mixture of washed silica sand and a third coat of the SE roof coating applied over the second coat of the SE roof coating, wherein the washed silica sand is mixed into the third coat of the SE roof coating at a rate of approximately two pounds per hundred square feet;
• wherein
• the second and third SE roof coatings are combined with the non-metallic flashing strips bonded to the decking panels to form the alternative roofing system.
