Built-Up Roofing
A built-up roofing system consisting of several layers of felt underlayment that is attached to the roof using a “hot mop” black tar method. The tar (bitumen) provides waterproofing, and the layers are generally covered with a layer of gravel or minerals to provide additional protection.
Built-up roofing systems exhibit exceptional resistance to the
conduction of heat between the exterior and interior of a building, resulting in noticeable reductions in heating and cooling costs.
If you are looking for a quality low-cost commercial roofing option in then a built-up system is for you.

Built-Up Roofing Manufacturers we Install in Kansas City
Johns Manville is not only a pioneer in developing BUR (Built-Up
Roofing) systems, but we created the very first BUR system in America
more than 150 years ago. Our continuous investment in developing
materials and manufacturing techniques has taken that heritage to a new
level, and today nearly one billion square feet of JM BUR systems are
under guarantee.
Why use BUR over other products? Because few other systems are so long
lasting, durable and worry free. With JM BUR systems, the highly
reliable waterproof membrane is field fabricated with layers of bitumen,
alternating with plies of reinforcing felts. The redundant layers give
it exceptional resistance to water and weather. We also manufacture a
complete line of fiber glass felts, including ply and base felts, and
mineral-surfaced cap sheets.
CertainTeed offers a traditional built-up roofing (BUR) system derives its name from the building of a roof on-site using layers of base sheet, interply sheets and cap sheet or other surfacing such as gravel or liquid coating.
Hot asphalt (bitumen) is the bonding and waterproofing agent between layers. BUR is suitable for most low slope roofing applications. The higher the quality of the BUR materials and asphalt used and the greater the number of plies (and separate asphalt moppings), the more superior the roofing system.
GAF offers many built-up roofing options with high performance, asphalt coated, glass-reinforced roofing base sheets. GAF Special Loctite™ closed-pore design prevents bleed-through while providing long-lasting leak protection in a variety of demanding applications.
GAFGLAS® Ply 4 Ply Sheet is used as a ply felt in the construction of built-up roofs. It is designed for use in all climate zones and is appropriate for use as a base sheet, as a ply felt, and in the construction of flashing membranes.
Firestone offers Ply IV (4) and Ply VI (6) asphalt impregnated, glass fiber mat reinforced roofing felts that can installed in multiple layers with a flood coat and aggregate or used in combination with modified bitumen.
The Ply IV (4) and Ply VI (6) felts provide superior durability and ease of application to construct Firestone Built-Up Roofing (BUR) Systems.
Tamko offers a wide range of low-sloped base and cap sheets for built-up roofing systems. Including Awaplan™ is created with a nonwoven polyester mat saturated with asphalt and coated on both sides with SBS rubber modified asphalt and surfaced with ceramic granules to help shield roofs from ultraviolet degradation
