Steel Roof Question

SO I am almost done with my pole barn. I've got all my posts set and my walls framed. I am planning on raising my trusses this Saturday. My question is how exactly do you secure the Steel to the perlins if you cannot walk right on the steel to do so? My Trusses are 4' OC with 8' 2x4 perlins. I was told that Trusses spaced 4' apart with 2x4 perlins will not adequate to hold the weight of a person. So how do I screw down the metal roofing?

Provided you have braced the trusses in all the right places so that they do not want to collapse like dominoes, I don't think you have anything to worry about. What is the spacing on your perlins? Is your metal roofing 36" wide? This will help to answer.

perlins are 24" and the metal is 36" coverage.

No worries. Either keep your feet directly over the perlins as you walk so as not to dent the metal, or if you aren't comfortable walking on it, put some planks across the bottom chord of the truss and reach out over the metal to attach it. The most you will have to reach is 3'- not hard to reach across at all. Impact drivers work best to start those screws.

A body harness and lanyard is usually recommended when doing this type of work.

SO I got the metal on the roof and sides with not problem. I found that walking on the metal roof was quite slippery with boots/shoes on so i did it barefoot (for the grip factor). Now my next questions:

What can I use to trim the 4 corners where the roof meets the siding on the two gables? I was thinking about buying a roll of white metal flashing and just bending it 90deg to fit correctly.

Also what can I use to trim the overhangs? The building has steel roof and steel siding. I do not necessarily want to use vinyl soffit if I dont have to. Thanks for all the input. I'll post some pics soon.

There is a prebent steel corner you can buy that you could use on the gable (rake) ends of a roof. They are usually 10' long, bent at a 90, and are about 5x5. They have a couple flared angles on them which helps keep them rigid.

For the overhangs, I wouldn't recommend you use vinyl either. I'd probably recommend Rollex aluminum soffit and Rollex steel fascia cover, since it's a little sturdier than aluminum. Not sure if you'd need a j-channel or f-channel against the building to recieve the soffit.
