Roof framing plan cut the six 2x6 rafters following the rafter template.

Framing a lean to roof with overhang.

Use a razor blade to cut it and have it the size of the roof. Re check for level and then drill lag screw or bolt pilot holes through the ledger and into the house s framing. Notch a birdsmouth where it sits on the low wall and extend it past the wall for the eaves. For shingles or 24 o c.

Mark the rafter layout onto the wall plates and ledger as shown in the roof framing plan then install the ledger flush with the back side of the rear wall. Cut the 2x6 ledger at 70 and bevel the top edge at 26 5 degrees so the overall width is 4 5 16. Use 1 2 plywood for the roof sheets. Use this measurement to cut a length of 2 4 making sure that one side of the board is miter cut to match the peak of the roof.

Begin by measuring from your extended fascia to the peak of the shed. When attaching ledger board to an existing wall install proper flashing when required. Attach the ledger with 1 2 inch diameter lag screws or bolts every 16 inches or as specified by local building codes. Leave no gaps between the sheets and align everything with attention.

If it is needed cut the metal roof panel to the length you need with tin snips hopefully you don t have too. Make cuts to the sheets and lay them on top of the roof structure. Lean to shed roof framing. Temporarily nail or brace the ledger in place positioned and leveled at the desired height.

Design lean to roof per your local building codes. A lean to roof just means it s attached to an existing structure. The high end of the rafter sits on or attaches to a ledger plate attached to the existing wall. Use right size of rafters and headers.

Once cut check to make sure the two lengths of 2x4s meet uniformly at the roof peak. Do the same for the other side. The lower end is done the same way a skillion or shed roof is.
