Roof Recon, an industrial waterproofing and roofing solutions company, says it has created a waterproof system for metal roofs. The system uses a waterproof washer and a bitumen-infused sponge made of polyurethane that acts as a seal. It has better adhesion, self-healing properties and, when compressed and indented at the washer's bolt hole, is 100% waterproof.
