Wind chill temps hit the Northern Plains yearly
Freeze-thaw cycles every single winter
Of storm damage is invisible from the ground
Yearly inspections recommended by pros
Surface Deterioration.
Northern Plains freeze-thaw cycles force moisture deep into aging shingles, splitting them from within. Curling
edges, cracked surfaces, and bare patches leave your roof deck fully exposed — and once heavy snow accumulates,
those weak points become active leaks.
Ventilation & Insulation Failure.
Thick icicles along your eaves signal warm air escaping through an under-insulated attic. That escaping heat melts
roof snow unevenly, which refreezes at the eaves and forces meltwater back under shingles — a leading cause of
interior water damage across the Northern Plains.
Structural Compromise.
Northern Plains winters routinely deliver 12-18 inch snowfalls that accumulate rapidly. A sagging ridge, visible
dips between rafters, or spongy decking indicate the structure has been weakened by moisture or age — and may not
support another heavy snow load safely.
Joint & Seal Failure.
Flashing around chimneys, vents, skylights, and valleys is punished by extreme temperature swings — often shifting
60°F+ within 24 hours across the Northern Plains. Metal expands, contracts, and eventually separates, giving
wind-driven snow and meltwater a direct path inside.
Shingle End of Life.
Granules are your shingles’ armor against UV rays and hail impact. When gutters fill with coarse, sandy debris,
that protective layer is failing. The Northern Plains’ brutal combination of summer hail and winter ice strips
granules faster than milder climates.
