How many layers of felt should a flat roof have?

A flat roof should have at least three layers of felt to provide adequate protection from the elements.

Definition of a flat roof

A flat roof is a roof that has no slope. Flat roofs are typically made up of three layers of felt: the roofing felt, the underlayment, and the finish felt. The roofing felt is the layer that is closest to the ground, and it is made of a soft, durable material. The underlayment is a layer of material that is placed between the roofing felt and the finish felt. The underlayment is made of a harder material than the roofing felt, and it helps to protect the roofing felt from moisture and weather damage. The finish felt is the layer that is closest to the sky, and it is made of a more durable material than the underlayment.

Overview of felt roofing

There are a few things to keep in mind when installing felt roofing. First, make sure that the felt is properly installed and that the roof is properly sealed. Second, make sure that the felt is of the correct thickness. Too thin a felt layer will not provide the necessary insulation, while too thick a layer will cause excessive weight and wind resistance. Finally, make sure that the felt is replaced regularly to ensure that it remains in good condition.
