When it comes to re-decking, I see basically 3 ways. Tear off everything and start over, replace just what is rotted here or there, or re-deck right over the top.
A few random questions.
I assume it’ll always be cheaper to either spot replace or over the top. On a 30 sq roof, at what point is it cheaper for the customer to just have you go over the top - IE, how many bad sheets total where you have to pry them up, cut to fit, etc, where the labor is just too much to make it worth not going over the top?
Is there any problem with going over the top? Can the deck be so bad you have to tear off the old deck and put a new one on?
Is there ever any point where tearing everything off and starting over (say, if that’s the code in FL) is cheaper than spot replacing? I have to check the code again, but I believe there is something in there about at a certain percentage replaced you have to replace all. Hell, I’m not even sure if going over the top is allowed down here.
What’s a fair price per 5/8" ply sheet installed?
