Built-up roofing systems (BUR) consists of layers or plies of roofing felts, between which asphalt or bitumen is applied. Built-up roofing is one of the oldest and most durable systems available. Its multiple layers provide extra protection and perform well in extreme weather conditions. Built-up roofs are especially resistant to damage from wind, hail and snow.

• BUR surfacing materials can be coated with reflective materials to reduce the effects of UV radiation. These coatings provide the additional benefit of reducing cooling and heating costs.
• State-of-the-art equipment enables such items as temperature monitoring, odor reduction and application efficiencies
• Specialized metal edges, designed specifically for BUR and Modified applications may be used
