A single ply, one-step roofing membrane that can be left exposed to the elements. Silt sizes are ideal for roofing, patching, gutter repair, flashing and any hard-to-waterproof area. Composed of a laminate of reflective aluminum foil, rugged, cross-linked polymer films and a thick layer of rubberized asphalt. The asphalt adhesive aggressively adheres to most surfaces and self-seals around punctures to form a waterproof barrier. Requires no coatings or covering for exposure to sunlight and is flexible to conform to odd shapes.
