Steel roofing
I dont know how old you are or how long you plan on haveing this building, but most good quailty steel has a 20 or 30 yr warrenty.Ive got several steel roofs and none have rusted yet.The good steel panels are plated [they call it electrogalvanizing],then epoxy coated.My oldest one is 15yrs, and looks the same as when built.Do not use treated wood for the purlins, this will destroy the steel.Fasten it with grommeted screws,not nails. The nails will loosen up in time and leak.The screws can be snugged up if this happens, the nails cannot.Drill the holes for the screws before you un-band the steel.Drill thru all the sheets at once,your screws will be all spaced the same and you wont scratch up the steel trying to drill up on the roof while keeping the layout straight.If your pitch is less than 3/12, you may want to use double stick urethane tape at the joints. Silicone, or rtv does not hold up for the long haul.Do not use the tape at any butt joints, just the laps.
