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

Framing a lean to roof with overhang.

Once cut check to make sure the two lengths of 2x4s meet uniformly at the roof peak. The lower end is done the same way a skillion or shed roof is. Leave no gaps between the sheets and align everything with attention. 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. Make cuts to the sheets and lay them on top of the roof structure. Cut the 2x6 ledger at 70 and bevel the top edge at 26 5 degrees so the overall width is 4 5 16. 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.

Space rafters either 16 o c. Lean to shed roof framing. Temporarily nail or brace the ledger in place positioned and leveled at the desired height. Re check for level and then drill lag screw or bolt pilot holes through the ledger and into the house s framing.

Use right size of rafters and headers. Use 1 2 plywood for the roof sheets. Attach the ledger with 1 2 inch diameter lag screws or bolts every 16 inches or as specified by local building codes. Design lean to roof per your local building codes.

Use a razor blade to cut it and have it the size of the roof. Do the same for the other side. For shingles or 24 o c. The high end of the rafter sits on or attaches to a ledger plate attached to the existing wall.

Drill pilot holes and insert 1 5 8 screws every 8 along the framing. When attaching ledger board to an existing wall install proper flashing when required. 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.
