Hello all I have a few problems &questions.Well I have a garage that is 32ft l x 24ft w it used to be a gable roof but it finally gave in.Well I started to fix it using some new&some salvaged materials but I working by myself decided a simple pitched shed roof would be better with me going at this alone.I messed the pitch up.The garage roof starts off at 7 ft then 12 ft later ends up at 10 then 12 ft later at 12 then 12 ft later at 12&a half so you see how I screwd up.Im new to this&its a long stupid story of why I did this anyhow that being said.I did this last year&at the time I used rolled roofing but now wanna use metsl but seing at one point its almost flat Im not sure if the metal would lay flat or if I would have to use a break&bend the metal.I would be using corrugated metal.Also if I couldnt and had to use shingles how many bundles to cover 36x24???The rolled roffing sux.
