BUR roofs are composed of alternating layers of bitumen and reinforced fabrics creating a finished membrane. The fabrics are reinforced with either fiberglass or polyester.
Surfacing for BUR roofs includes aggregate, glass fiber or mineral surface cap sheets, and others. Roof coatings can be applied to surfacing material to reduce the effects of UV radiation, and provides the additional benefit of reducing air conditioning and heating costs.

1. Roof slope
2. Roof drainage
3. R-value
4. Structural load capacity
5. Roof deck deficiencies
