We have a cottage with a ceiling/roof constructed with tongue & grove pine. Although the walls are insulated the roof is not and when we use the cottage in the winter and when the furnace heats the inside, the snow and ice start to melt on the roof and an ice dam forms at the eavestrough backing the water up under the shingles. We only use the cottage two or three times during the winter and I am wondering if I should remove the eavestrough for the winter months. Would that stop the damming?
Answer:
Not necessarily and it certainly wouldn't stop the wood rot in the roof decking. That has already started so you might check to see how much damage that's done.
