Modified Bitumen Roof Layers

Insulation used to provide r value or thermal resistance for temperature stability of the roof system.

Modified bitumen roof layers.

Modified base sheets or plies. The main advantage modified bitumen roofing has over most other commercial roofing systems is that it is extremely tear resistant. Provides r value or thermal resistance for temperature stability of the roof system. Modified bitumen membranes factory fabricated sheet membrane composed of co polymer reinforced with polyester or fiberglass.

The 5 layers involved in the creation of this roof can be used in many valid combinations to create unique protection. A compound known as modified bitumen makes up the second and fourth membrane layers of each sheet of torch down roofing material. What makes modified bitument roofs different. It is assembled in a unique permutation of layers that compound to increase the roof s effectiveness.

Modified bitumen roofs have some really useful components. Bitumen is an asphalt compound. Modified bitumen flat roofing is a single ply system made of asphalt bitumen modified with polymers and reinforced with fiberglass and or polyester. This is due to the combination of fiberglass and or polyester reinforcement layers.

Materials such as layers of fiberglass or polyester are added to the asphalt to add strength to a flat roof. The framework for modified bitumen roofing systems is a five layer combination of roofing components. Repairing a rooftop with modified bitumen coating. The big issue with repairing a modified bitumen roof surface is the question of whether moisture has made its way into the asphalt layer and if so how much.

For the third layer of a three layer roof granulated mineral surface. The base layer provides waterproofing and a surface for the cap to bond to. This feature makes modified bitumen roofing the ideal choice for low slope commercial roofing with high foot traffic. Modified bitumen is a 2 part low slope roof system that is made when polymers are added to asphalt to change its properties.

Determine the extent of the damage. It s necessary to inspect the modified bitumen roof.
