We bought a house and this past winter immediately noticed abnormally MASSIVE icicles hanging from the gutters and roof edge, surrounding about 90% of the house. Some of these icicles are a few feet long and weigh a lot. This is NOT normal, but I wish I knew what is causing this. I also noticed that right underneath the roof overhang surrounding the whole house, the painted wood seems to be cracking and rotting! Is this caused by the icicles? Would our 'maintenance-free' 'LeafGuard' gutters cause this?
What needs to be done to fix this issue? Thanks for your help in advance.
