Usually, you must file a wind damage claim within the deadline written in your insurance policy, not by one single Minnesota rule. Many policies allow about 12 months from the date of loss. Some cut that to 60 to 90 days. File as soon as you suspect damage, because late notice can sink an otherwise…
Yes. In Minnesota, an ice dam can trap meltwater uphill of a skylight, then push that water under shingles, flashing, or a membrane curb. The leak may show at the skylight frame, drywall, or several feet away. Condensation can look similar, so the source needs to be traced before permanent repairs begin. A skylight is…
Yes. Freeze-thaw cycles can crack chimney counterflashing in Minnesota, especially where mortar, sealant, or fasteners already have movement. Water gets in, freezes, expands, and opens the gap wider. By the time you see a ceiling stain, the leak path may already include brick, flashing, sheathing, or the roof deck. Key Takeaways Quick scan Freeze-thaw damage…
Usually only a few days to a few weeks. A roof tarp in Minnesota is a temporary dry-in measure, not a season-long fix. Wind, UV, freeze-thaw cycling, snow load, and fastening method control how long it lasts. If the tarp is still up after the immediate emergency, it’s time to move toward inspection and permanent…
Short answer: A roof that leaks during snow melt but stays dry in rain usually has a cold-weather drainage problem, not only a simple hole. Melting snow moves slowly, backs up behind ice or frozen drains, and can slip under seams, flashing, or roof edges. On commercial roofs, thaw cycles also expose hidden moisture paths…
Yes. On many commercial roofs, water enters at one point, then travels along seams, insulation, metal deck flutes, or framing before it drips inside. That means a ceiling stain can appear several feet away, sometimes much farther, from the actual roof damage. The interior drip marks the exit point, not always the entry point. If…
Yes. Wind can loosen, bend, lift, or tear off coping caps on commercial flat roofs, especially at parapet edges and corners. Once the metal edge opens, water can move behind the roof system, soak insulation, stain walls, and raise blow-off risk in the next storm. Treat wind-damaged coping caps as a functional roof problem, not…
Yes. Heavy snow can cover wind-lifted seams, bent edge metal, loose flashing, and small punctures until thaw exposes them. On commercial roofs, the first clear sign may show up in spring as interior leaks, wet insulation, or shifted membrane. That’s why winter storm damage often needs photos, temporary dry-in, and a focused post-thaw inspection. When…
Yes. A satellite dish roof leak can show up after hail because the storm often damages the weak points around the mount, not the dish itself. Fasteners can loosen, sealant can crack, flashing can shift, and cable-entry details can open. On commercial roofs, water may travel away from the breach before it appears indoors. For…
Yes. TPO roof shrinkage can cause edge leaks when the membrane pulls against perimeter flashing, fasteners, and welded details until gaps open. Water often enters at the roof edge before you see stains inside. The risk is higher on older roofs, roofs with repeated temperature swings, and systems that already have stressed seams or weak…
Yes. A fishmouth seam on a TPO roof can leak when the membrane lifts, the weld never fully closed, or water tracks under the overlap. Small, dry wrinkles may stay harmless for a while, but any open seam, staining, or wet insulation turns it into a real leak risk. These defects matter because seams are…
Yes. Tree branch scuffs can look like hail damage, especially on flat roofs with weathered membranes, coatings, or light-colored surfaces. The difference usually shows in the pattern. Branch marks are dragged or directional, while hail leaves scattered impact marks. If the roof also has leaks, the damage may call for repair, not just a visual…
