1. The supports: It will be necessary to place several supports on your patio/roof, so the maximum separation between the supports of the sheets should be between 105 and 115 centimeters. In the supports it is also essential to use straps to fasten the plates between walls or rooms of the house. For this, we must install even beams.

2. Overlaps: They are necessarily attached to the slope of the roof. The overlaps between plates of sheets will be a minimum of 30 centimeters. The overlaps can also be vertical.

3. Drains: Depending on the shape of the sheet metal plates, the water that falls from the rain will be expelled either outwards or towards a gutter that will direct it towards the funnel to be drained. If there is no gutter, you must install it yourself or else the water will fall freely to the outside.
