Different Flat Roofing Replacement Materials

EPDM Membrane Roofing: The complete form of EPDM is ethylene propylene diene terpolymer. This is a synthetic rubber membrane that is commonly used for commercial industries.

TPO Membrane Roofing: TPO means thermoplastic polyolefin, which is a single-ply white membrane majorly used for residential and commercial both purposes. While the EPDM absorbs the heat, the TPO reflects the heat. If you are looking for a flat roof over the bedroom, TPO can be a good choice as it tends to keep the room cooler.

The significant difference between these two is that PVC is slightly more flexible than TPO. You can expect more than 25 years of lifespan from the roofing option.

Metal Roofing: The standing seam metal roofing consists of more than two or more metal roofing panels that are seamed mechanically. The best part of the metal roofing option is the better aesthetic and color options and its longevity compared to the membrane roofing options.
