Modified Bitumen Roof Layers

Determine the extent of the damage.

Modified bitumen roof layers.

The main advantage modified bitumen roofing has over most other commercial roofing systems is that it is extremely tear resistant. Materials such as layers of fiberglass or polyester are added to the asphalt to add strength to a flat roof. The 2 part system consists of a base layer and a cap layer. Modified bitumen is a 2 part low slope roof system that is made when polymers are added to asphalt to change its properties.

Repairing a rooftop with modified bitumen coating. The 5 layers involved in the creation of this roof can be used in many valid combinations to create unique protection. The base layer provides waterproofing and a surface for the cap to bond to. Modified bitumen roofs have some really useful components.

Layer 1 insulation. Modified bitumen membranes factory fabricated sheet membrane composed of co polymer reinforced with polyester or fiberglass. What makes modified bitument roofs different. Modified bitumen flat roofing is a single ply system made of asphalt bitumen modified with polymers and reinforced with fiberglass and or polyester.

A compound known as modified bitumen makes up the second and fourth membrane layers of each sheet of torch down roofing material. This is due to the combination of fiberglass and or polyester reinforcement layers. Modified base sheets or plies. Insulation used to provide r value or thermal resistance for temperature stability of the roof system.

For the third layer of a three layer roof granulated mineral surface. Modified bitumen roofing is a roofing asphalt. It s necessary to inspect the modified bitumen roof. It is assembled in a unique permutation of layers that compound to increase the roof s effectiveness.

The framework for modified bitumen roofing systems is a five layer combination of roofing components. This feature makes modified bitumen roofing the ideal choice for low slope commercial roofing with high foot traffic.
