TPO roofing is a relatively inexpensive rubber roofing material that is frequently on commercial buildings. TPO is short for Thermoplastic Polyolefin; it’s made primarily from recycled rubber, and sold in rolls that are held together by seams that are “glued” together using heat.

This type of roofing is best suited to flat roofs, or those with a very low pitch. While this type of roofing can be very cost-effective.
