How is membrane roofing installed?

After the existing substrate is prepared, either by cleaning or removing the existing roof, the insulation layers are installed. Generally, a cover board is placed on top for the membrane to be adhered to. The membrane is then attached to the cover board one of three ways: Ballasted.

How are commercial flat roofs constructed?

These roofs are composed of layers of asphalt paper and moped down hot liquid tar, which is why it is called “built-up roof.” The paper is layered in a criss cross pattern and depending on the contractor, as many as 12 layers of paper and tar can be used during the installation.
