Flat roof materials explained.
Most commonly thermoplastic roofing membranes are made from a compound called polyvinyl chloride pvc or one called thermoplastic olefin tpo.
Membrane roofs are attached in a variety of ways.
Any roof with a slope of 3 in 12 or less is considered a low slope roof and the roof covering on a low slope roof is called a membrane.
They use plasticizers to impart flexibility making them an extremely versatile roofing material.
If the slope is less than 2 12 the roof is considered flat.
Because of the low slope these roofs do not shed water very quickly high winds may cause water to actually move up slope and water may sit on some parts of the roof for days.
This protective membrane goes under some or all of the asphalt shingles to prevent water infiltration caused by ice dams in winter.
To an untrained eye one flat roof looks very much like another especially from the ground level but in fact there are several different flat roof systems to choose from.

1 bur built up roof this flat roof systems contains layers of waterproof membrane tar and gravel to seal the flat roof surface.
The materials on flat roofs are mostly rubber.
This causes the insulation to sustain damage and the membrane has parts of the insulation adhered to it making it non recyclable.
In some cases we can completely remove the fasteners and take apart the roof system making all components reusable.
To make a flat.
There are three types of roofing systems used for rubber membrane roofs.
