Prestige, yeah I am thinking about purchasing one if I do well this year but won't make the plunge until next summer. We do not really have snow and salt issues here where I am at. It rarely ever snows here (once every few years and it's not really snow, more like ice). I do want a lift to work on my personal hot rods though and to do things like under carriage painting, brake work, wheel work, etc.
As for the roof idea, I just lease the building so most likely will not do much to it that will be major investment. The land lord is a tight wad and an *** and doesn't even live in this state. He will not even repair a leaky roof but good thing my father owns a roofing and construction company in case I have any problems. The roof on it now is a rubber/foam type membrane roof that is thick and spongy which helps some instead of your typical felt/hot mop roof. Insulating with R30-R38 insulation will cost about $2600-$3500 depending on which one I go with. I heard from a few people that you can have a company come do the work installing and bring the materials for cheaper than I can buy the materials myself and install so we will see... Next on my list is walls then flooring. I also found a HUGE portable A/C system which is over $3000. I can probably get A/C put back into the shop for $1000-$2000 but I thought about the portable being a good investment because I can take it with me. I found one on Craigslist that will cool a 3200 sq ft building. Tomorrow I may go pick a small one up at Lowes for the office.
