A standing seam metal roof system is a type of roof that uses panels with raised seams to create a watertight seal. The panels are typically made of steel or aluminum, and they can be either mechanically seamed or snap-lock.
TPO stands for thermoplastic polyolefin, a single-ply roofing membrane that covers the surface of the roof. The name is a bit misleading, because rather than being a plastic, TPO is actually one of a few different types of rubber, usually a blend of polypropylene and ethylene-propylene rubber.
PVC roofing or polyvinyl chloride is a single-ply roofing solution used on commercial or industrial roofs that are flat or low sloped. PVC or polyvinyl chloride, is the third-most widely produced synthetic plastic polymer.
EPDM is an extremely durable synthetic rubber roofing membrane (ethylene propylene diene terpolymer) widely used in low-slope buildings in the United States and worldwide. Its two primary ingredients, ethylene and propylene, are derived from oil and natural gas.
Modified bitumen roof systems can be installed with the common torch method, asphalts, or cold adhesives. A standard SBS modified bitumen roof system is a two-ply system applied in rolls that overlap the edge of the previous roll
Mod-bit (MB) is a shorter way to say modified-bitumen. MB roofing systems are a durable, weather resistant type of low-slope roof. Mod-bit materials are sold in rolls, and its seams are sealed using heat (the common open flame torch), hot- or cold-applied, or self-adhering. The base sheet that the roofer mechanically attaches to the roof deck with cap nails or disc plating ensures excellent protection from wind uplift.
Roof shingles are a roof covering consisting of individual overlapping elements. These elements are typically flat, rectangular shapes laid in courses from the bottom edge of the roof up, with each successive course overlapping the joints below. ... They are a very common roofing material.
