Articles tagged snow. Sellers Roofing handles Minnesota winter roof issues — ice dams, snow load, ventilation, and insulation — across Saint Paul and the Twin Cities.
Asphalt shingle freeze-thaw damage from the freeze-thaw cycle usually shows up as shingle cracking in tabs, curling edges, lifted corners, blistering, and granule loss creating bald spots. The damage often clusters near eaves, valleys, and shaded slopes, because trapped moisture undergoes expansion and contraction, freezing and expanding to slowly break the shingle surface apart. Key…
Yes. Snow can cover bruises, granule loss, and small cracks on asphalt shingles until thaw. It can also keep the surface wet and cold, which makes soft impact marks harder to spot. By spring, melting, drying, and freeze-thaw cycles often reveal damage that looked minor, or invisible, in winter. When This Applies Which commercial roofs…
Usually, yes, Minnesota insurance may cover ice dam damage if the loss is sudden and the policy covers resulting water damage. It often pays for interior water damage and related roof repairs, but not routine maintenance or preventive ice removal. Claims get harder when poor insulation, weak ventilation, drainage issues, or long-term neglect helped cause…
Bathroom fan roof vent leaks usually show up as ceiling stains, drips at the fan grille, wet insulation, or rust around the roof cap. In Minnesota, snow, ice, and freeze-thaw cycles often crack flashing or sealant around the vent, so a small drip can point to a bigger roof issue fast. When This Applies This…
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…
Start by inspecting the rubber pipe boots where they hug the pipe, then the base flashing where it meets the roof. Look for radial cracks, splits at the top edge, loose sealant, and lifting edges from freeze-thaw. On Minnesota commercial roofs, check after big temperature swings and after snow events, then document damage and schedule…
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…
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…
After harsh Minnesota winters that batter roofing materials with heavy snow and ice, focus your spring roof inspection on vulnerable spots like drains and scuppers, seams and flashing, roof edges, and rooftop penetrations (HVAC curbs, vents, skylights). Once the snow melts, check for ponding water, split sealant, loose coping, punctures from snow removal, and new…
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…
What maintenance should be done on a roof includes routine inspections, clearing drains and debris, checking seams and flashing, fixing small punctures fast, and documenting all work. How do you maintain a commercial roof? Set a schedule (at least spring and fall), add post-storm checks, manage snow load, and address freeze-thaw damage early so you…
A roof drip edge, or roofing drip edge, is a metal flashing installed along roof edges to push water away from the fascia and roof deck, and into the gutter system. In Minnesota, you usually do want it because snowmelt, ice, and wind-driven rain can sneak under shingles and rot wood edges. It’s not always…
