A. A built Up roofing system is a continuous, semi-flexible, multiply roof membrane consisting of plies or layers of saturated felts, coated felts or glass mats between which alternate layers of bitumen are applied. Generally, built up roof membranes are surfaced with mineral aggregates and bitumen, a liquid applied coating or a granular-surfaced cap sheet. Application of this system is generally on hot asphalt, cold tar pitch or cold adhesive, per manufacturers specifications.
