Black Swan's Roof Proof is a roof and flashing cement formulated to work on wet and dry surfaces under all weather conditions. Recommended for the repair of holes, tears and rips in roofing. It is ideal for sealing flashings, vents, laps, etc. Adheres to concrete, metal, wood, tile, built-up roofing, asphalt, shingles and masonry. Roof-Proof is a combination of pure asphalt and selected fibers. Meets Federal Specification SSC-153.


Holes and cracks, as well as the surface around them, and any other areas over which the material is to be applied, should be clean. Clean out cracks with an old whisk broom. Rust and scale on metal should be wire-brushed clean. Concrete should be wire-brushed to remove all loose particles. Use material as it comes and apply with a trowel at a thickness of 3/8 to 1/2 inch. Always taper off the cement to a feather-edge.

Large Holes - Cut a piece of canvas, roofing, metal or felt larger than the hole. Apply Roof-Proof in and around hole. Place the patch down and trowel cement over it.

Small holes and Cracks - No patch is needed. Merely trowel material in and around opening and smooth to a feather-edge.

Laps, Seams and Loose Nails - Drive in loose nails and apply material over and around nail heads and seams.

Flashings - Material should always be used under and over metal flashings. Be sure metal is nailed tight wherever it contacts wood.

Gutters - Apply a thin layer of this cement with a stiff brush inside gutter. Work material well into gutter junctions.

Slate and Tile Roofs - One application seals joints and cracks.

Parapets and copings - To insure a waterproof seal, apply a 1/2 inch coating over-all, being sure to work cement well into cracks.

Concrete - Work Roof-Proof well into cracks and smooth off

Cold Weather Application - If this cement becomes too heavy to work, submerge this container in a bucket of hot water to restore its workable plasticity. DO NOT HEAT OVER AN OPEN FLAME.

Locating Leaks - It is not always easy to locate the source of a leak. The trouble spot often is not directly over the point at which it shows on the underside of the roof. Carefully inspect the roofing seams and flashings and repair such spots which seem most likely the cause. If first efforts fail, repair other likely spots.
