Ice damming and freeze-thaw
The single biggest threat to a Canton Township roof is ice damming at the eaves. 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. Canton Township has a large stock of ranch homes and bi-levels from the 1970s and 80s. Those low-pitched roofs accumulate ice dams faster than steeper colonials. If your home is a ranch or split-level and you’ve had repeat eave leaks, ask us to inspect both the shield coverage and the ventilation balance.
