BTW.... many roofers will actually try to get away with not installing "eave protection". I swear it's the truth. I have seen it many times, even on NEW houses! Make sure your roofer installs it and does it right.

Of course, eave protection is really just a backup. Proper insulation and ventilation is the key. Again, CMHC has lots of good info on how to do things right... and wrong.
