Modified Bitumen | Longhorn Commercial Roofing in Austin, TX

Matt Parker - Sunday, October 15, 2017

Modified Bitumen is an asphalt-based roofing product, similar to the Built-up-Roof (BUR) designed for low-slope or flat roofs. It offers the benefits of a BUR roof, but also offers additional strength, flexibility and UV resistance. Modified Bitumen provides multiple layers of protection, and tolerates extreme environmental elements. Various methods are used for the installation of this type of roofing system, including the hot torch method and sealant-backed peel and stick rolls. Modified bitumen roofing ensures your business is protected from the elements and can save you money on energy consumption. Longhorn Commercial Roofing in Austin, TX can provide you with the roofing solution you need.

The layers that define Modified Bitumen consists of the following:   

1. Insulation  provides temperature stability of the roof system.

2. Modified base sheets and plies.

3. Modified Bitumen Membranes are composed of co-polymer reinforced with polyester or fiberglass for added strength, resisting tears and punctures.

4. Adhesive is combined with a waterproofing material, and can be applied either hot or cold.

5. Surfacing  includes a factory application, a gravel application, or a liquid applied roof coating, and others. Provides UV protection and additional weathering resistance.

Types                           

There are primarily two types of modified bitumen roofing. Styrene Butadiene Styrene (SBS) and Atactic Polypropylene (APP). Both can be reinforced for added strength and a long service life. SBS has the properties of elongation and recovery. This enables it to better deal with stresses from temperature extremes, wind, and the typical contraction and expansion. APP is more plastomeric whereas SBS is more elastomeric. APP ensures the weathering better but lacks the flexibility of SBS. They differ in the method of installation. Styrene Butadiene Styrene (SBS) is typically installed with either heat welding, hot asphalts or cold adhesives. Atactic Polypropylene (APP) will almost always utilize the hot torch method in its installation process, but can be heat welded or utilizing a cold-application of adhesives.
