Yes. Strong wind can lift or tear starter shingles at the eaves, especially if the seal strip failed, nails were misplaced, or the roof edge lacks proper drip edge support. Once that first course loosens, water can get under nearby shingles and damage the edge system, which makes fast inspection and repair important. When This…
Nail pops on asphalt shingles show up as small, raised bumps where a shingle tab lifts because nail heads have pushed up. In the Minnesota climate, freeze-thaw swings make them easier to spot during late winter and early spring. Look for uneven shingle lines, lifted corners, exposed nail heads, and tiny cracks or granule loss…
Short answer: You’ll suspect roof decking rot when your roof system shows ongoing moisture infiltration plus structural “softness.” Inside, watch for recurring ceiling stains, musty smells, or bubbling finishes. On the roof, look for ponding water, failing seams, or spongy areas that flex under safe, limited foot pressure. In Minnesota, freeze thaw cycles and Minnesota…
Metal roof hail damage usually shows up as visible dents, chipped paint or coating, loosened flashing, and dings along seams, ribs, and trim. In Minnesota, Minnesota weather’s freeze-thaw cycles can turn small impact marks into rust spots or leaks later. The key is separating cosmetic denting from functional damage that affects water-shedding and fasteners, compromising…
Kickout flashing is a small, shaped piece of metal installed where a sloped roof ends against a wall, right above the gutter. Its job is simple: push roof runoff into the gutter instead of letting water slide behind siding. In Minnesota’s snow, ice, and wind-driven rain, its absence can lead to water damage and moisture…
A TPO wall flashing leak, a common roof leak on a flat roof, is usually found by tracing water from the interior stain back to the nearest wall, then inspecting the roof to wall flashing where the TPO membrane turns up the wall. Focus on terminations (termination bars, counterflashing, reglets), corner patches, fasteners, and sealant…
Ponding water on a flat roof is rain or snowmelt, often referred to as “standing water”, that sits in low spots instead of draining away. In Minnesota, it becomes a real problem when it stays longer than 48 hours, keeps coming back after normal storms, or pools near seams, drains, and penetrations. A simple ruler…
To vet a roofing contractor, check credentials first, especially given the harsh Minnesota weather, then verify insurance in writing, then pressure-test their reputation with detailed reviews and real references. For commercial buildings in Minnesota, licensing can be confusing, so confirm local requirements and ask who will pull permits. Finally, watch for red flags like vague…
Creased shingles usually look like a clear, sharp bend line across a shingle tab where strong wind lifted it, then slapped it back down. In Minnesota, you’ll often see lifted corners, a shadow line at the fold, and missing granules along the crease. The shingle may not reseal, even on warm days, which raises leak…
Poor roof ventilation usually shows up as moisture, frost, heat buildup, or uneven roof temperatures, and you can often spot it in minutes from the attic hatch. Proper roof ventilation maintains balanced airflow and prevents these issues. In Minnesota, the clearest clues are winter frost on nails, damp insulation, moldy smells, and ice-dam patterns. If…
Short answer: The Minnesota ice barrier code requires an ice barrier at roof eaves on many heated, shingle-style sloped roofs. The barrier must extend from the eave edge to a point at least 24 inches inside the exterior wall line (measured on the roof). The code language does not require ice barrier in valleys, and…
Roof shingles are the overlapping outer roof covering on sloped surfaces. Their job is simple but critical: they shed water, protect the roof deck underneath, and take the hit from sun, wind, and impacts like hail. For commercial business owners, shingles often show up on office entries, retail storefront canopies, and older properties, even if…
