Flat roofs in Minneapolis take a beating from the humid continental climate. Cold snowy winters pile on heavy snow loads that stress seams while warm humid summers trap moisture under the membrane. Ponding water around drains is the top failure point we see on buildings in the North Loop and Uptown.
We use 60-mil TPO or reinforced EPDM on most commercial jobs because those hold up to freeze-thaw cycles better than cheap modified bitumen. Hennepin County requires permits for any tear-off over 100 squares, and inspectors check fastener patterns and flashing heights. Skip that step and you get red-tagged fast.
Cheap crews often skip proper tapered insulation or use the wrong plate fasteners on metal decks. That leads to blow-offs during spring storms along the Mississippi Riverfront. We always pull permits first and match the existing slope so water moves off the roof instead of sitting.
