- Choosing Materials. First, you need decide what materials will be used for your new flat roof.
- Removal. The old roofing materials will be removed with special tools.
- Replace Damaged Plywood. Before a new roof is installed plywood damaged by water or fungus needs to be fixed. The beams need to be correctly situated to prevent pooling water.
- 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. Then, hot asphalt is mopped down into rows on top of the felt to make the roof waterproof. These rows continue overlapping until the first layer is complete. The process of laying down felt and then mopping hot asphalt on top can be done up to 5 layers.
- Finishing Touch. This part is optional but you may choose to spread ballast or gravel on top of the finished roof to prevent damage if debris lands on the roof, and prevent damage from the sun. This can also be done with special paint, or a plastic coating.
