This system is applied in the same way as an EPDM system, with a slight difference. TPO is a more rigid system; it is adhered with a glue, but all seams are heat welded, as opposed to glued. TPO is a great choice when there is a possibility of the roof being exposed to chemical emissions.
Built Up Asphalt Roofing Systems (BUR)
BUR systems are the oldest type of systems. It consists of plies of roofing felt, embedded in hot asphalt. The surfacing is either gravel, a mineral surface cap sheet or a white/silver roof coating.
