I own a warehouse in Northern Ontario. I bought it dirt cheap and have been repairing it as needed over the years. It had three separate flat roofs when I bought it. I have converted two of them to pitched roofs and installed shingles.
It's time to do something about the third one, which is also the largest.
First of all, there are no commercial flat roof companies near me (within 100 miles, maybe even further).
What are my options and where the hell do I start?
I'll most likely bring in some type of contractor, but I would like to do my own research first and learn as much as I can to make a good decision.
Roof is 73x44 feet. 24 inch tall steel trusses (welded angle iron) space 9 feet apart. Trusses run the 44 foot distance and are clear span (no posts).
Roof is decked with painted steel decking. The bottom ribs have severe corrosion and holes. Some of it has visibly started to sag between trusses.
There are pitched roofs adjacent to this one (see first pic).
I need to look into the pitched roof conversion options. From what I've seen you can add supports and purlins on top of the existing trusses. Peak and eaves would have to be like the adjacent roofs (eave would be over the garage doors). Seems like this should be the correct option since I'm gonna have to replace decking anyway.
The pics below are the worst of the roof. You can see the janky fixes that got done when the adjacent apartment building was demo'd after it burned. Some of the blocks fell through the roof. It was fixed with wood and has the silver roofing tin underneath
