Abstract
A method of constructing a weatherproof coating over a roof comprises laying a piece or pieces of cloth over a roof, bonding the pieces of cloth together at any seams, adhering the cloth to the roof surface at least at the edges and projections, then coating the cloth with a liquid elastomeric silicone composition. The composition cures under ambient conditions to yield a water impermeable membrane that has been manufactured in place. A preferred embodiment uses unimpregnated, non-woven thermoplastic cloth having an upper surface thermally treated to remove projecting fibers, the thermally treated surface being subsequently wash coated with a layer of liquid elastomeric silicone emulsion except for any surface of the cloth edges which will be subsequently bonded at any seams, the wash coating being cured before application of the coated cloth to the roof.
