Built-up roofing systems are time-tested against water intrusion and well known for its self-healing properties.

Built Up Roofing (BUR) is one of the oldest and most reliable commercial roofing systems for low-slope or “flat” roof structures. Commonly referred to as “tar and gravel” roofs, BUR consists of layers or plies of roofing felts, between which asphalt or bitumen is applied. Its multiple layers provide added protection and perform well in punishing weather conditions. Built-up roofs are especially resistant to damage from wind, hail, and extreme sun.


Modified Bitumen roofing systems are one of the most time-tested roofing products on the market. It can be installed with one or multiple layers, depending on the roof’s substrate.

Modified Bitumen Systems are good heat reflectors because of the granules in the cap sheet. The granules are also a fire retardant. Modified systems should be installed on roofs with no less than ¼” slope in order to achieve positive drainage. When installed in single layers, a modified roof system has a 12-16 year lifespan. Multiple layers add to the life of the system. We offer many different warranties on our modified systems, including and up to 20-year no dollar limit warranties.
