Use right size of rafters and headers.

Framing a lean to roof with overhang.

Notch a birdsmouth where it sits on the low wall and extend it past the wall for the eaves. After is adding the metal panels you will want the metal to extend 1 2 past the framing will run from tall side to short. Roof framing plan cut the six 2x6 rafters following the rafter template. Do the same for the other side.

The lower end is done the same way a skillion or shed roof is. 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. 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. 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. Lean to shed roof framing. Leave no gaps between the sheets and align everything with attention. Use a razor blade to cut it and have it the size of the roof.

Use 1 2 plywood for the roof sheets. Design lean to roof per your local building codes. Once cut check to make sure the two lengths of 2x4s meet uniformly at the roof peak. Begin by measuring from your extended fascia to the peak of the shed.

Temporarily nail or brace the ledger in place positioned and leveled at the desired height. Make cuts to the sheets and lay them on top of the roof structure. Drill pilot holes and insert 1 5 8 screws every 8 along the framing. The high end of the rafter sits on or attaches to a ledger plate attached to the existing wall.

Re check for level and then drill lag screw or bolt pilot holes through the ledger and into the house s framing. For shingles or 24 o c. If it is needed cut the metal roof panel to the length you need with tin snips hopefully you don t have too.
