Thermoplastic Polyolefin (TPO) is a single-ply reflective roofing membrane made from polyprophylene and ethylene-propylene rubber polymerized together. TPO is typically installed in a fully adhered or mechanically attached system, allowing the white membrane to remain exposed throughout the life of the roof.
Spray Polyurethane Foam (SPF) roofing has many benefits, such as energy efficient, water proof, and is easy to maintain. SPF roofing can be sprayed on almost any type of roof, such as tar and gravel, metal, or even shingles. With the installation being as simple as it is, it will save you time and money.
TAR AND GRAVEL
Although tar and gravel roofs are durable, it is easy for leaks to develop. This is because tar and gravel roofing is especially sensitive to penetrations. Also known as “built-up roofs”, tar and gravel roofing consist of layers of asphalt and tar paper that are fastened to the roof surface with molten asphalt applications.
