Framing A Lean To Roof With Overhang

The lower end is done the same way a skillion or shed roof is.

Framing a lean to roof with overhang.

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. A lean to roof just means it s attached to an existing structure. Begin by measuring from your extended fascia to the peak of the shed.

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. Leave no gaps between the sheets and align everything with attention. 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. 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.

Use a razor blade to cut it and have it the size of the roof. Space rafters either 16 o c. Use 1 2 plywood for the roof sheets. Design lean to roof per your local building codes.

Re check for level and then drill lag screw or bolt pilot holes through the ledger and into the house s framing. 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. The high end of the rafter sits on or attaches to a ledger plate attached to the existing wall.

Notch a birdsmouth where it sits on the low wall and extend it past the wall for the eaves. If it is needed cut the metal roof panel to the length you need with tin snips hopefully you don t have too. Use right size of rafters and headers. Roof framing plan cut the six 2x6 rafters following the rafter template.

For shingles or 24 o c. Temporarily nail or brace the ledger in place positioned and leveled at the desired height. Lean to shed roof framing.
