Let's start with a simple rule for those who want to install a metal roof. If you cannot walk on the roof easily because it is too steep, call a professional. Now, this rule has come to an end, if you want to keep it, but can't do the bidding of professionals, how to set it up.
First proper means are required. These are a measuring tape, a chalk line with lots of chalk, a good drill, a safe extension ladder, step ladder idea, of pounds of inches with roofing nails, metal roofing screws, pieces of metal, and a cloth nail bag to hold nails and screws.

Measure the height of the roof and add the desired overhang, typically two to four inches. In the next section, find out how much metal edges are needed from both the length and height of the roof.
Take these measurements to your roofing supply company. They will tell you how much to buy. Remember that three to six inches of unblocked airflow between layers are required.
Although it is not necessary to remove the old one before laying the metal roof, it is best. Start placing metal sheets running from top to bottom.
Using a screw every two feet on both sides of the sheet, screw them into wooden slats. Each sheet should overlap the last. When you reach the edge, cut the last metal sheet, so it is in the back of the roof edge.
