WHAT GOES WRONG
WITHOUT THE RIGHT COMMERCIAL ROOF INSTALLATION
Left unaddressed in Milwaukee's climate, these are the failures we're called to fix most often.
Ponding water
Flat and low-slope roofs that don't drain hold standing water, which accelerates membrane breakdown and leaks.
Seam & flashing failures
Most commercial leaks trace to open seams, failed penetrations, and edge-metal details — not the field membrane.
Patch-on-patch history
Years of quick fixes by different contractors trap moisture in the system and hide the real problem.
