Will these metal roofing panels work for a lean to run?

[junior67]

I can get this for about $40 more total (from the 31 gauge ones) but will the extra 2 gauge make that much of a difference?

Yes.

Standard steel metal roofing is 29 gauge, some folks opt for 27 gauge. The chart below shows the difference between 31 vs 29 gauge to be approaching twice the thickness, well worth an extra $40.

Also keep in mind that with 24" centres on the rafters as well as 24 inch separation on the purloins you have spec'ed the very least strength structure "generally allowed" (sheds often do not have building codes) . Your purloin separation means fewer roofing screws and therefore less resistance to wind force.

I would do 16" OC for the purloins and 29 gauge for the metal.

Thank you. So rafters 24 on center and purloins 16 on center?

Would you choose metal roof or plywood with shingles? Plywood works out cheaper since we have shingles, but seems metal may be easier/quicker.

You can do 24" OC just make sure you align the rafters to the studs and put a double plate on top of the walls.

I prefer metal for a roof and it is easier/quicker to put on a roof with no gullies.

Sometimes I am brain dead.

Obviously if the stud wall is 24" on center and the rafters are 16" they cannot all align.

Align the 1st and 4th rafter in each 4' length to the 1st an 3rd stud in each 4' length. The 2nd and 3rd rafters cannot align to a stud but will be adequately supported by the double horizontal top plates.

Thought what I have seen rafters are good at 24 on center. So thought those were ok to stay that way? Think with our other build we did studs and rafters 24 on center.

So thought it was the purloins that were 16 on center?

@junior67 You are correct on both points.

I must be tired...

well that is a first that I am right on something with building. LOL

 

[aart]

It will be 16' long should I put in some type of beam in the center of it?

Your rafters are spanning 6', correct?
Then you would not need a center beam for support.

My husband is in construction/HVAC but is also a good handyman. But for coops and runs he leaves it on me since I do the research and know what we need and want. but I have ZERO building experience (well besides helping with our existing set up) so I never know what is easier/better etc.

Certainly he could advise you tho, right?

Yes spanning 6'.

You would think he could. He did most of the build last time and went by my drawing and made the correct changes. Lol
