Detroit averages 40 freeze-thaw cycles each winter. Water expands nine percent when it freezes. That expansion force splits shingles, cracks flashing seals, and opens gaps in roof valleys. Each cycle widens existing damage. A hairline crack in November becomes a quarter-inch gap by March. This is why preparing your roof for winter in Detroit is not the same as winterizing a roof in milder climates. The repetitive stress is relentless. Homes near the Detroit River and in low-lying areas like Corktown experience even more moisture exposure, accelerating deterioration. If your roof is not sealed tight before the first freeze, you are already behind.
Detroit building codes require ice and water shield underlayment in vulnerable areas, but many older roofs were installed before these requirements.
