Fluid Membrane In Low Slope Roofs

With about 22 of low slope commercial roofing projects using metal systems according to scott kriner technical director of the metal construction association we wanted to see how metal compares.

Fluid membrane in low slope roofs.

For a low slope residential roof there are two main options. Liquid membrane roofing systems. Modified bitumen membrane roofs must have a design roof slope of 1 4 12 or greater 2 slope. Technically we are talking about low slope roofs that have a slope less than or equal to 3 12.

The membrane will outlast the shingles and seal around all nail penetrations. This patented technology provides a durable finish with the ability to match existing roofing compositions. Get to know more about one of the most popular commercial roofing systems. Learn about liquid membrane roofing systems.

Finding the right products for your low slope roof. As with single ply membranes there are toxicity concerns around some of the materials involved particularly coatings. These membranes are particularly effective for roofs with a very low slope between 1 8 12 1 and 4 12 33. Concrete is electrically conductive.

Residential low slope roofing can generally be divided up into two broad categories. 1 cover the entire surface with a self adhesive flashing membrane such as grace ice water shield there are many equivalent products. The life of structurally sounds roofs through their ability to eliminate many failure points associated with many aging low slope roofs. Then apply standard asphalt shingles over the membrane.

Minimum slope for a membrane roof. For this type of roof shingles and other traditional coatings are less durable and less aesthetic. These membranes are particularly effective for roofs with a very low slope between 1 8 12 1 and 4 12 33. Larger flat roofed applications low slope such as residential condominium complexes row homes and town houses and smaller applications such as residential porch and garage transitions from the main home where the slope of the roof changes dramatically.

The use of the self adhesive base ply membrane sa smooth ply 40 as a first layer and the self adhesive granulated cap sheet membrane sa cap gr or sa cap fr gr as a second layer is an ideal solution to ensure the waterproofing of low slope roofs. Minimum roof slope roof pitch r905 11 1. Inverted roofing assemblies where the waterproofing membrane is applied directly to a structural concrete slab can be effectively eld tested without modifications to the roofing assembly. The use of the resisto self adhered waterproofing membrane as a first layer and the resisto granulated cap sheet high resistance hr cap sheet as a second layer is an ideal solution to ensure the waterproofing of low slope roofs.

Thermoset single ply roofing minimum roof slope roof pitch r905 12 1. When we say flat roof we don t mean perfectly flat which is undesirable since water still needs to be shed to roof drains. For this type of roof shingles and other traditional coatings are less durable and less aesthetic.
