Westend, from what my caculations are, its going to take 6.5 sheets to do the roof, I had planed on redoing the entire roof, or at least adding some luan to the good decking, but i'm in the process now of undoing the trim and pulling up the membrane, the stuff is so old it is brittle, and you can see who ever had it before and tried to patch or paint over it, use a roll on liquid rubber, but he didn't do the whole roof just around anything attached like the railing, ladder and ac. it looks crappy and it doesn't stick to well. the actual rubber membrane is brittle and is just ripping apart.
As far as budget is concerned I have enough right now to cover the cost of plywood. that not an issue. the $500. will be for just the water proofer. so that is where i am at. i can't take this thing anywhere as it don't have tags, and don't plan on tagging it unless absolutely necessary, I figured last night i decided that I wasn't going to be hauling it around it will basicly become a man cave and hangout section for where it is at, with a garden around it and pond and all. if i ever decide to get rid of it I'll salvage what i can and tear it down and use the frame for some thing else. I'll eventually redo the side wall maybe adding T111 paneling eventually or something but thats way down the road.
our habitat for humanity places around here suck, its all clothing and furniture, nothing hardware. we been to them before for supplies for other people. But I actually have kiltz primer Like i said I am always building something and have a ton of supplies.
What would you suggest for filling in the viods and joints of the plywood, regular wood filler? or should i seam it with tape?
As far as the Ac and vents, I was thinking of pulling them up and doing the roof with what ever I decide. and then putting it all back in place and using some gaskit for the ac or some lap silicone or something to water proof it all back up, what would you suggest, ( also the strips to cover the seam screws broke on me they were so brittle and dry rotted, So what do you suggest for covering up the seem screws, do they make those strips for the metal seams? or can i just use lap culk.
