26ga vs 29ga roof once again

[supratreo]

Quick question for you guys. i'm deciding on roofing and siding at the moment and I was pretty set on 26ga figuring a little heavier material would be better until I contacted a local supplier.
1. the colors available depends on the gauge of the material i go with so in order to get the color i want i might have to go with 29ga.
2. she recommended that i go with 29ga to save some $$ if the panels will be going on covered walls. this didn't cross my mind before but obviously i will have sheathing on the roof and all walls. 15/32 OSB is whats called out.
I do understand that if your putting this on a bare frame you probably want to go thicker but what do you guys think in my situation?
the plans also call out for exposed fasteners but i'm leaning towards getting siding/roofing with concealed fasteners.
thank you

Depends on how nice you want it and how much you're willing to spend. Regular R panel and external screws work fine for a lot of uses. Hidden fastener seam lock looks cool but it probably costs significantly more than R panel. My house has the former, the shop the latter.

the hidden fastner panels cost about 2x as much so i'll have to decide on how much i want to spend. mainly concerned with 26 vs 29ga.

I like to use the thicker metal but when I was younger we built a lot of smaller 2-3 vehicle pole barn metal buildings. Concrete was subbed out, then we'd frame one day and sheet/roof/trim the next day. Most of those buildings were not sheeted with OSB and had the thinner metal. We had to be very careful not to kink the metal but all of the buildings I've driven past over the years are still standing tall and looking good. We are in a dry climate but have snowy winters so maybe that matters.
I sheet my buildings with OSB and use 26awg metal but in your case I might go with 29awg over OSB in order to get the color you want. I usually see the finish on metal (especially blue for some reason) fade long before the metal has problems regardless of the thickness.

Thank you for bringing up another point.
i'm assuming all finishes are not the same? i've see some buildings after many years have faded or the finished completely came off. is this due to poor quality? how would i know what i'm getting or am i thinking too much into it.

also, no snow here. just high temps and a lot of sun in the summer and cold winter night can get to 30ish.

I think the fading here is caused by the sun exposure. Blue seems to be the worst and green seems to be next. I also saw a brown one that was very faded but it was probably 30 years old. Most other colors hold up well. If there is reflected sun like on the side of a building next to a sidewalk I've occasionally seen some peeling but it's pretty rare, more common with metal siding around here. I don't know if it's just something to do with the colors or manufacturers or what.
My buildings are mostly gray with white or galv-alume roofs and have held up well.

I wouldn't go any less than 26. 29 guage is for small storage sheds.

29 makes a good interior liner panel too.
