Built-Up & Modified Bitumen Roof Systems

Built Up (BUR)
Roof Systems

A Classic But Effective Roofing Solution

Wood Roofing and Sheet Metal offers dependable built-up roof systems (BUR) for every type of commercial building. BUR systems, also known as "tar and gravel" roofs, are a trusted choice, providing over a century of proven performance for various commercial applications from industrial roofing to office building roofing. These multi-layered roofing assemblies provide excellent water resistance and long-lasting protection. Our team of union roofing contractors in Des Moines is highly skilled in BUR installation, ensuring a leak-proof, energy efficient, and durable roof solution for your business for years to come.

WHAT IS A BUR ROOF SYSTEM?

Built up roof membranes, referred to by the acronym BUR, have been in use in the U.S. for more than 100 years. These roof systems are commonly referred to as "tar and gravel" roofs. BUR systems generally are composed of alternating layers of bitumen and reinforcing fabrics that create a finished membrane. Built-up membrane installation for commercial roofing systems can either be hot applied or cold applied using modified asphalt.

TYPES OF BUR ROOF SYSTEMS

BUR roof systems come in two basic types, asphalt and coal tar, and three basic components: the waterproofing component, the reinforcing component, and the surfacing component which is used to protect the other components from the elements.

Wood Roofing and Sheet Metal offers trusted modified bitumen roofing systems for every commercial roofing need. This reliable roofing option is a popular choice for flat and low-slope roofs because it’s both durable and affordable. We implement only the highest quality roofing materials using well-proven techniques. This guarantees your property will benefit from the superior longevity, versatility, and energy-saving properties of Modified Bitumen roofing systems. Our experienced Des Moines roofers can help determine if a modified bitumen system is the right solution for your commercial building.

WHAT IS A MODIFIED BITUMEN SYSTEM?

Polymer-modified roof membranes are composed of reinforcing fabrics that serve as carriers for the hot polymer-modified bitumen as it is manufactured into a roll material. MB roof system membranes are composed of multiple layers, much like BUR membranes. MB roof systems typically are installed as a two-ply system and almost always are fully adhered.

TYPES OF MB ROOF SYSTEMS

The two general types of polymer modified bitumen membrane systems are Atactic Polypropylene (APP) and styrene butadiene styrene (SBS). Each of these polymer-modified roofing products differs in their chemical characteristics. Both types are heavyweight membranes reinforced with either polyester, fiberglass or a combination of both.
