Are Metal Roof Ice Dams Different From Shingle Ice Dams?
ByTed Sellers September 16, 2026September 16, 2026

Short answer: Yes. Metal roof ice dams can form when attic heat melts snow above a cold roof edge, as they can on asphalt shingles. Both systems can develop ice dams under those conditions, but water behaves differently. Backed-up water can move beneath shingle tabs, while metal roofing can carry it under panels, seams, transitions,…

ByTed Sellers September 8, 2026September 15, 2026

Short answer: Yes. Wind-driven snow can enter attic vents in St. Paul during cold, gusty storms, especially through exposed soffit, gable, or poorly baffled ridge vents. A light dusting may dry without harm. Repeated snow in attic vents, wet insulation, roof-deck frost, or ceiling stains needs a closer inspection. Minnesota winters combine powdery snow, sustained…

Can Snow Block a Bathroom Fan Roof Vent in Minnesota?
ByTed Sellers August 6, 2026August 6, 2026

Yes. Can snow block a bathroom fan roof vent? It can, especially after wind-packed snow or a thaw that refreezes at the cap. A snow blocked roof vent traps bathroom moisture in the duct instead of releasing it outdoors. Clear the obstruction without climbing onto an icy roof, then check the cap, damper, duct insulation,…

Can Attic Air Sealing Prevent Ice Dams in Minnesota Homes?
ByTed Sellers July 31, 2026September 19, 2026

Short answer: Yes. An attic air sealing ice dams plan can stop heat leaks that melt roof snow, then refreeze it at cold eaves. It won’t solve every ice dam. Deep snow, weak insulation, blocked ventilation, roof defects, and poor drainage can still cause ice buildup and water entry. When Attic Air Sealing Ice Dams…

What Should You Do About Wind Damaged Gable Vents?
ByTed Sellers July 22, 2026August 1, 2026

Wind damaged gable vents need fast documentation, temporary protection if rain can enter, and a roof level inspection. Photograph the vent, surrounding siding, attic insulation, shingles, and any interior staining before permanent work begins. A cracked louver can be a small gable vent repair project, but wind can also loosen flashing, disturb shingles, or expose…

Can Summer Heat Crack Asphalt Shingles in Minnesota?
ByTed Sellers July 21, 2026August 1, 2026

Yes. Summer heat can dry and stiffen asphalt shingles in Minnesota, making older shingles more likely to crack, curl, or lose granules. Heat usually is not the only cause. Age, poor attic ventilation, hail impacts, winter freeze-thaw movement, and past installation issues often weaken the roof first. A hot July day then exposes the problem….

ByTed Sellers July 17, 2026September 19, 2026

Yes, clogged gutters ice dams are a frequent concern for homeowners during harsh winters. While clogged gutters can exacerbate the issue by trapping meltwater at the eaves, they are not typically the original cause of the problem.

Can Recessed Lights Cause Ice Dams in St. Paul Homes?
ByTed Sellers July 16, 2026August 1, 2026

Yes. Recessed lights ice dams are a real concern, as these fixtures can cause or worsen ice formation when warm indoor air leaks through the housing and into a cold attic. This specific type of heat loss warms the roof deck directly above the fixture, melting the snow and sending water toward a colder eave…

Can Ice Dams Damage Gutters and Fascia Before a Leak?
ByTed Sellers July 14, 2026August 1, 2026

Yes. Ice dams can bend gutters, pull fasteners from fascia, split wood trim, and loosen roof-edge flashing before water ever reaches the interior of your home. This type of structural damage often occurs when melting snow refreezes at cold roof eaves, building a heavy ridge of ice that traps additional water and exerts constant, destructive…

Do Heated Roof Cables Prevent Ice Dams on Minnesota Homes?
ByTed Sellers July 3, 2026August 1, 2026

Yes, but only in a limited way. Heated roof cables can reduce ice buildup at eaves, valleys, and gutters, which helps water move off a Minnesota roof during freeze-thaw cycles. They do not fix attic heat loss, bad ventilation, or an aging roof. On a damaged roof, they are a support tool, not the repair….

Can Attic Frost Be Mistaken for a Roof Leak in Minnesota?
ByTed Sellers June 9, 2026August 1, 2026

Yes. In Minnesota, attic frost often gets mistaken for a roof leak because it melts and drips onto insulation, framing, and ceiling tiles during a thaw. The key difference is timing and pattern. Frost comes from indoor moisture freezing inside a cold attic, while a true roof leak usually tracks back to exterior damage, failed…
