Ice damming and freeze-thaw
The single biggest threat to a Wyandotte roof is ice damming at the eaves. Wyandotte’s post-war brick ranches are especially prone — low-pitched eaves and attics that were never vented to modern standards trap heat and accelerate the ice-melt cycle. When snow melts off a warm attic, refreezes at the colder eave, and backs water up under the shingles, you get leaks in your ceiling. Two things prevent ice dams: ice and water shield extending at least 24 inches inside the heated wall line (Michigan code minimum), and properly balanced attic ventilation. If you’ve had ice dam leaks before, ask us to inspect both.
