Modified Bitumen Roof Repair in Lewisville

Choose Calidad Enterprises for your modified bitumen roof repair & installation needs. A Modified bitumen roof  uses a polymer modified bitumen that is reinforced with one or multiple layers of fabric like glass fiber, polyester, or a mixture of both. The installation process for a modified bitumen roof can be completed using conventional methods, for example, self-adhered and hot or cold application. There are a few types of modified bitumen roofing materials to choose from:

  • Atactic Polypropylene (APP) – This type of modified bitumen roofing is a thermoplastic polymer that is either heat-welded or torch-applied. It is known to give asphalt a plastic-like quality.
  • Styrene Butadiene Styrene (SBS) – This type of modified bitumen roof is installed using cold adhesive or hot moppings of asphalt. It may also come with adhesive backing. Modified bitumen SBS conveys a rubber-like appearance.

Modified bitumen is manufactured in factories and sold in sheets. It is specially made to have equal thickness and physical properties throughout the entire sheet. A finished roofing membrane can have one or several bitumen sheets, but it can also have a combination of built-up roofing felts and one or more modified bitumen sheets.

Why Choose Bitumen Roofing?

Modified bitumen is recommended for commercial roofing in the North Texas area and the surrounding areas because of these four characteristics:

  1. Strength & Durability – Both types of modified bitumen roofing can withstand both high and low temperatures due to polymer modification. The number of sheets also improves durability.
  2. Waterproof  Surface– The types of adhesives used to attach modified bitumen provide a seal of protection against water damage
  3. Prolonged Longevity – This type of roofing can last up to 20 years without the need for too much maintenance.
  4. Energy Efficiency – This type of roofing material comes with an insulating layer that limits the flow of heat throughout the system.
