Things I've learned with my shop Bob. The roofs' ridge allows leaves and bugs in. When the rain is blowing, rain gets in there too. Ask about a way to seal that up. Knowing what I know now, I would 100% spray foam the entire damn thing. I had a white roof put on and in the summer, it's like a freakin easy bake oven in there. I open the doors for the nice breeze, but the radiated heat from the sun on the metal is ridiculous. If you're having this put up, I ask your contractor to put screws in the rib of the roof, not the flats. I can't for the life of me, understand why anyone would put the screw hole in the flat where the water actually runs. Kind of on that note, make sure your panels run vertical and not horizontal, to permit maximum water run off. Make sure the drainage around your building can handle the amount of rain outflow for when we have these 10" of rain in a week monsoons. (one corner of my building pad floods with heavy rain) Also ask your builder if he will run a compactor over the crushed concrete or just track it in? It will make a difference in how long before it starts degrading.

Mostly...once it's done, get out and enjoy it! Hope you get to go out and strum that Dobro on a peaceful summer night and just listen to the nature and pic some good tunes.

Dave, Great points to consider! Thanks. The "dirt" guy and the contractor both said they need to bring in a red dirt (clayish I suppose) base about 3 or 4 " then bring in the Crushed concrete around 3 or 4 inches as well. The contractor said he has a site with the crushed concrete and he has heavy equipment and 18 wheelers driving across it. I will ask the contractor about these items.

IMO you need that rear roll up door. Why go to the expense of building it and not going thru with making it right? Being able to pull thru is a game changer.
