  4. First wooden or synthetic can’t strips are installed into the corners, and a base sheet is laid and nailed down (if required according to roof type). Flashings are installed to prevent leaks, along with plastic roofing cement. Next, layers of coal-tar or asphalt saturated felt will be laid down starting from the lowest point in the roof.

The process of laying down felt and then mopping hot asphalt on top can be done up to 5 layers.
