How Much Should A Metal Roof Overhang
A metal roof should overhang the eave end of a roof 1 to 1.5 if you have gutters. If your roof does not have gutters, your roof can overhang up to 3. A minimum overhang of 1 is always recommended to prevent rain and other moisture from blowing up under the metal roof edge.
You should not overlap the rake ends of your roof with your metal panels. While some overhang is acceptable on the eaves, you should never overlap rake edges as too much surface area of the panel would be exposed to wind and you would risk the panel failing in extreme weather.
Layout And Cut The Tail Of Rafter
The tail of the rafter also forms the eaves. From the birdsmouth plumb line, horizontally the distance for the eaves. Using the framing square at the slope references for the rise over the run on the top of the rafter, measure from the plumb line to the desired measure. Draw another parallel plumb line using the square. That is the end of your rafter. The size of the facia determines the depth of the rafter end. Use the square to measure down the end plumb line the thickness of the facia. Draw a horizontal line from the desired facia thickness toward the birdsmouth. Cut the 90° angle to form the rafter end.
You now have a pattern for all common rafters.
Lean To Shed Roof Framing
A lean-to roof just means its attached to an existing structure. The high end of the rafter sits on or attaches to a ledger plate attached to the existing wall. The lower end is done the same way a Skillion or shed roof is. Notch a birdsmouth where it sits on the low wall and extend it past the wall for the eaves.
