Roofing using 2x4.

There is a chance of damaging roofing sheets if you are failed to do so. If you have a simple gable shed roof then using 2 4 rafters makes more sense unless you have a very large shed. 60 pieces 2x4 x12 feet boards. For roofs that will experience heavy snow or wind and will span the same distance use 2 6 rafters.

Built on 4 12 pitch roof with 1 2 ply decking and shingles. For this example a section of roof is 20 feet wide. One foot overhang so could say 11x16. 2 pieces 12 feet aluminum.

A rough 2x4 had a lot more strength that a finished one. The wider the roofing panels the greater spacing distance you should put. The width of metal panels will determine the rafter spacing. I put 2 2x4 joist about.

It s made 11 winters here and look like the day i finished it. Measure each section of the roof from side to side parallel to the line of the fascia board. Rafters to 2x4 with joist hangers. The metal roof purlins spacing must be done correctly within narrow tolerances.

5 pieces 2x4 x12 feet boards pressure treated. 1 3 of the way from each in to keep it from spreading from snow load. 2x4 x8 feet boards. Front and sides will sit on deck on a 2x4 wall with studs 24 oc and screened in.
