The ideal roof slope for the climate is 5 12 or better.
How to build a lean to roof of my shed.
Building lean to roof.
Measure the width of the outside wall and cut the board with a circular saw to the same length.
We added the gable trim after we finished painting the whole shed this way we would not get paint on the trim.
Angle the roof so rain is directed away from the building s perimeter.
Step 1 make a ledger board to fasten to the existing wall and support the upper end of the lean to roof.
Also attach on the side along the framing front.
Then place the gable trim and attach using the 1 5 screws.
After you ve built the frame of your shed floor add 4 skid beams for support and cover them with plywood.
That means for every 12 inches or foot the roof runs.
Then screw your joists to wooden beams at the front and back to form the shed floor.
This shed features front and back overhangs.
Also decide how the roof of the lean to will interface with the roof of the shed.
It goes up 5 inches.
You can also easily add side overhangs to the roof of the shed if you want.
And that is how we built a lean to roof for a shed plus installed a metal roof.
The steeper the slope the faster it sheds snow ice and leaves so less build up.
To build a lean to shed start by cutting lumber into joists that are the width you want your shed to be.
You may need a simple gutter or downspout drainage piping to prevent pooling at the base of the lean to.
If your region receives heavy snowfall build the roof to withstand that load.
