My cost for 26 gauge is now running .74 a sq/ft...trim averages $1.20 a lineal foot....prices have doubled for materials, but since a lot of hacks, and other roofing companies got in the act, the market price hasn't risen in comparison. Consequently, it is not as lucrative to do metal installs, as it once was. When I quote a roof now, I generally do a take off on material, and estimate days x miles, plus freight on the roof, and upcharge for steep slopes, etc, etc. If I don't get the job, and I still get probably 1 in 3 I bid on, I don't cry about it, because we are making money. My minimum for installs is $120 a sq now, including basic trim. A 12 on 12 slope will double that.
I am close to 5 steel building manufacturers, and all of them will roll steel panel roofing, including SSR. It is a competitive market here....and now you know why I don't get serious about my own machine....MBCI has about any special panel profile available I could want, and why try to stock material?
It may make sense for you to get a machine, but here, it would be dicey, since panelized roofs are common, you would be trying to sell an upscale product that is tough to do. If metal roofs were much higher then they are now, there would be fewer of them here.
