Things You'll Need:
- saw with metal cut blade, tape measure,
-
Step 1
The first step and most importation is the first roll, this would be started from the highest point of your flat roof. [note no roofs a 100% flat, they have at least a 1-12 pitch] Its very importation that it gets double flashing from the shingles on to the side wall then cap flashing on the top. The [L] flashing should be started off the metal shingles then work up the wall and then covered with [Z] flashing before being caped. This would also be the way it would done when the roof/slope runs along the a wall. Note: some flat roofs do not sit on the very top of the building/home they sit between the walls with a draining system in place others slope down one way [normaly to the back] to run water off the building.

Step 2
Installing the rest of the shingles after the first roll is done with a drill and screws. [check your metal shingle manufacture for the requirements for screwing each one] You should install them one roll at a time, the chances of installing them and then running into install trouble or leaking trouble is very low. They come with a simple snap and go system making them very simple to install the right way.

Step 3
Finishing up, depending on the type of shingle/materials you go with will result in how much finish work is left after running all the shingles. Some manufactures have pre-made channels for the sides and every other parts of the install requiring little to no finish work/flashing after the last one is in place. Others will require you to cap and flash all the edges like seen in the detail/picture in step one.
