Rio Blanco Roofing & Restoration is a San Antonio Modified Bitumen Roofing systems (MBRs) leader. Modified bitumen is an evolutionary offshoot of asphalt roofing used primarily for low slope or flat roofs. That is, while asphaltic roofing components are used in the manufacture of MBRs, they are combined with a series of solvents and modifiers to optimize them.
Furthermore, Rio Blanco Roofing & Restoration enjoys the customization ability of MBRs. We use 5 different components that can be combined in several ways to form an MBR roof to fit any requirement. For instance, Rio Blanco Roofing & Restoration can use an initial insulation layer to form a strong foundation or substrate for the roof. We can then place a lower ply sheet layer under a modified bitumen based ply. In addition, we can use a modified bitumen membrane layers that consists of either polyester or fiberglass matting for our San Antonio area roofing applications.
Once these steps are complete, Rio Blanco Roofing & Restoration can hold together the layers and components using either a heated or unheated asphaltic adhesive. That is, we can connect the layers and segments using thermal catalysts to merge the asphalt in order to provide a protective seal. Although this method is seldom used in San Antonio roofing applications, we can use a subzero cooling process to apply the asphalt. These days, we most often find ourselves recommending and using the new Self-Adhering Modified Bitumen Membranes. They have many advantages over the older more classic methods of modified bitumen installation. Regardless of the application process, Rio Blanco Roofing & Restoration would then protect the layers with a weather protective surface finish to provide UV protection and topmost flashings to provide waterproof protection around the roof’s surroundings.
The most common roofing bitumen variants that we currently use are roofing Atactic Polypropylene (APP) and Styrene Butadiene Styrene (SBS). APP is less expensive but also has lower impact resistance, while SBS has superior impact resistance but is more costly. In addition, SBS modifiers give asphalt a “rubber-like” texture while APP modifiers cause roofing asphalt to exude a plasticized aesthetic. Hence, MBRs provide a wide range of combinations to create the ideal roof for your residential, commercial or industrial San Antonio area low slope roofing needs.
MBRs provide several benefits. For instance, MBR components are resistant against fire, splitting, and thermal shock. Moreover, we use a roofing bond that is foolproof and time-efficient. Furthermore, we believe that the various combinations at our disposal offer possibilities for optimal durability, style, and elemental resistance. Thus, MBR systems offer Rio Blanco Roofing numerous benefits and colors that allow us to provide you numerous options at very cost-effective rates.
