What i had tried to do was to use a tractor for a power supply for a Wood chipper. I have most of the stuff i was trying to use. Got pretty much ready to get it modded up. The wife's unkle came by. He is an unemployed builder. He suggested I extend the garage so i have a place to store those tractors. He figure $800.00 tops for the project. 24'x 20' No concrete or siding. But he had another grand idea why not put a dormer on both sides for storage? Well ok. Added 13 TGI trusses and 3/4" tongue and groove plywood for a platform to work on and to make use of the dormers. The metal roofing was almost $900.00
I'm not sure if i should coat the tgi trusses with anything to reduce the effect of moisture on them. But i wish i could have just stuck with the wood chipper project. I wouldn't be so worn out and it would at least have been tested by now. I'm worn out, I don't have anything done yet, but the tractors will be more or less dry. The lumber price is depressed. That 3/4" tongue and groove use to be over $30.00 a sheet. I got it for 16.00.
Steel is not depressed. The roof is a 7/12 pitch and I am worn out from trying to stay on it while i am screwing it to the 2x6 rafters. I never applied for a job of roofing i knew there was a reason.
