Ice damming and freeze-thaw
Ice damming is the biggest cold-weather threat on Clinton Township roofs. When attic heat melts snow, it refreezes at the colder eave and backs water up under the shingles — leaks in the ceiling follow. Clinton Township has a lot of ranch and split-level homes with low-pitch sections where ice backup pressure is worse than on steeper-roofed colonials. The fix is ice and water shield at least 24 inches inside the heated wall line and balanced attic ventilation. If you’ve had repeat ice dam leaks, both usually need to be addressed at once.
