Framing A Lean To Roof With Overhang

A lean to roof just means it s attached to an existing structure.

Framing a lean to roof with overhang.

Once cut check to make sure the two lengths of 2x4s meet uniformly at the roof peak. Cut the 2x6 ledger at 70 and bevel the top edge at 26 5 degrees so the overall width is 4 5 16. Use a razor blade to cut it and have it the size of the roof. Notch a birdsmouth where it sits on the low wall and extend it past the wall for the eaves.

Design lean to roof per your local building codes. Use 1 2 plywood for the roof sheets. Leave no gaps between the sheets and align everything with attention. The lower end is done the same way a skillion or shed roof is.

For shingles or 24 o c. 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. Lean to shed roof framing. 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.

Space rafters either 16 o c. Attach the ledger with 1 2 inch diameter lag screws or bolts every 16 inches or as specified by local building codes. Use right size of rafters and headers. Do the same for the other side.

Roof framing plan cut the six 2x6 rafters following the rafter template. 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. The high end of the rafter sits on or attaches to a ledger plate attached to the existing wall.

If it is needed cut the metal roof panel to the length you need with tin snips hopefully you don t have too. 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. When attaching ledger board to an existing wall install proper flashing when required.
