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, sometimes, but only on a roof that meets Minnesota code and has the right structure beneath it. A roof overlay in Minnesota can work on some single-layer asphalt roofs, but not on roofs with two layers, soft decking, trapped moisture, or mixed materials. For commercial owners, that matters most on sloped entries, additions, and…
Yes, an asphalt shingle roof replacement can happen in a Minnesota winter, but the job depends on weather, roof condition, and the crew’s method. Cold air makes shingles stiffer, and the seal strip may take longer to bond. If the day is dry and stable, winter work can be safe and effective. If snow, ice,…
Yes. Hail can dent, loosen, or split chimney flashing while the shingles around it still look fine. That happens because flashing is thinner, more exposed, and sealed at edges that hail can stress. If the flashing fails, water can enter even when the roof surface looks untouched, so the real test is function, not appearance….
Usually, yes, especially on a commercial roof. A roofer helps the adjuster spot hidden damage, separate old wear from the new loss, and document the scope if the roof may need commercial flat roof repair or even commercial roof replacement. If the claim is simple and the roofer can’t attend, the inspection can still move…
Attic roof storm damage is easiest to spot when the clues are fresh. Look for new water trails, wet insulation, daylight through the roof deck, split wood, rusted fasteners, and stains that line up with a recent hail or wind event. If the space is unsafe, or there is no true attic, call a roofer…
There is no single percentage that fits every roof, but widespread granule loss usually changes the answer fast. Small, scattered bare spots can often be repaired or watched, while large areas of exposed asphalt, repeat leaks, brittle shingles, and worn edges usually point to replacement. On a commercial building, the right call depends on how…
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…
Yes. Hail can dent, loosen, or split skylight flashing while the glass stays intact. On a commercial roof, that matters because flashing is often the first place water gets in. A skylight can look fine from the ground and still leak, stain insulation, and signal that a commercial roof needs repair. When This Applies Signs…
Yes, if the leak is isolated and the membrane around it is still sound. TPO roof patching can work more than once when each repair bonds to clean, dry material and the rest of the field still holds. Once the same area keeps leaking, seams fail across the roof, or insulation gets wet, a larger…
Start with safety, then check the roof in layers. Look from the ground first, photograph dents, splits, and missing granules, and only climb if the surface is stable. On a detached garage, garage roof hail damage often shows up on edges, flashings, and metal trim before it shows through the ceiling. If you find leaks,…
Yes. Flat roof foot traffic can crush insulation, scuff membranes, loosen seams, and create small punctures that stay dry for a while. The roof may look fine after the walk, then fail later when the same area gets more stress or the next storm pushes water through a weak spot. When This Applies Regular roof…
