Built-Up Roof Repair
Built-up (BUR) roof systems are commonly referred to as “tar and gravel” roofs and are generally composed of alternating layers of bitumen and reinforcing fabrics that create a finished membrane. The bitumen typically used in BUR roof systems is asphalt, coal tar or cold-applied adhesive. BUR’s are typically topped with rocks or gravel as well, but use a thin layer of pea gravel or crushed stone as opposed to much larger stones in a ballasted roof. A majority of leaks and built-up roof repair will occur at flashing details – anywhere the membrane itself is terminated or interrupted.
BUR roof systems are not fluid-applied like seamless roofing systems so they cannot be custom installed and tailored to meet the particular issues of each individual roof – like flashings, vents, HVAC units, etc. A built-up roof repair is recommended around penetrations and the edges of the building to stop leaks but that will only result as a short-term fix. Surface spudding, repairs and installation of a seamless roofing system will make your roof stronger and more durable than the day it was installed.
