Minneapolis experiences dramatic temperature swings during spring and fall. Daytime temperatures reach 50 degrees while nights drop below freezing. This cycle stresses commercial roof membranes and exposes weaknesses in parapet wall flashing. Ponding water on flat roofs freezes overnight and expands, opening seams in EPDM rubber membranes. When temperatures rise, meltwater enters through these compromised areas and saturates insulation above suspended ceilings. The water migrates laterally through ceiling tiles before dripping into occupied spaces below. By the time you see ceiling stains, thousands of square feet of insulation above may be saturated. Large scale water extraction must address both the visible damage and hidden moisture in ceiling plenums to prevent mold growth and continued water intrusion during the next freeze cycle.
Commercial properties in Minneapolis require restoration companies familiar with local building department requirements.
