Framing A Lean To Roof With Overhang

Use a razor blade to cut it and have it the size of the roof.

Framing a lean to roof with overhang.

Space rafters either 16 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. A lean to roof just means it s attached to an existing structure. Notch a birdsmouth where it sits on the low wall and extend it past the wall for the eaves.

Begin by measuring from your extended fascia to the peak of the shed. Use right size of rafters and headers. Roof framing plan cut the six 2x6 rafters following the rafter template. Attach the ledger with 1 2 inch diameter lag screws or bolts every 16 inches or as specified by local building codes.

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. Drill pilot holes and insert 1 5 8 screws every 8 along the framing. The lower end is done the same way a skillion or shed roof is.

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. Re check for level and then drill lag screw or bolt pilot holes through the ledger and into the house s framing. 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. Use 1 2 plywood for the roof sheets.

Leave no gaps between the sheets and align everything with attention. The high end of the rafter sits on or attaches to a ledger plate attached to the existing wall. Design lean to roof per your local building codes. Do the same for the other side.

Temporarily nail or brace the ledger in place positioned and leveled at the desired height. Once cut check to make sure the two lengths of 2x4s meet uniformly at the roof peak. When attaching ledger board to an existing wall install proper flashing when required.
