COAL TAR PITCH SYSTEMS

COAL TAR PITCH SYSTEMS

Coal Tar Pitch roof system consists of multiple plies of felt with interplies of Coal Tar Pitch, then embedding gravel in a floodcoat of Coal Tar Pitch. Many roofers who have been in the industry a long time believe a coal tar pitch roof system is the best system ever, because of its self-healing properties. You can have a leak one day from a hole and then on a hot day, coal tar pitch becomes soft and will flow into or over the hole or leak without any effort or expense to the owner.

Coal Tar Pitch has many advantages. It is designed for flat roofs with no slope and is immune to ponding water and many chemicals. While most roof designs have changed, it was not uncommon 50 years ago to find a Coal Tar Pitch roof designed to hold as much as three inches of water. Water was put on the roof to keep it cool so it wouldn’t flow. Coal tar is a long lasting roof and can be maintenance free for up to 50 years.
