Fall is upon us and winter is close by. I know I'm sorry!
Today lets talk about Ice Damning & why and how it occurs. The real cause of Ice Damning is energy loss(Heat Loss) from walls and attic areas. Ever wonder why it seems to start at the edge of your roof area or in the valley?
The area directly above a homes walls is "around" 8" tall plus or minus, to the underside of the homes roof sheeting. A poorly insulated wall/attic allows that warm air to radiate upwards.
This radiation of heat causes a constant thawing/warming of that area and when the melted snow or rain gets past that point it re freezes and causes Ice Damning to form.
Some Roofers will tell you all you need is Ice Shield 3' up from the edge of the sheeting.
Ice shield does protect the sheeting from ice damage however it will do nothing to stop Ice Damning. Proper wall and attic insulation/Soffit Venting/Insulation Baffles are the cure for the problem.
Also keep in mind that a clogged gutter system also plays a Hugh part in creating Ice Damning when it is full of frozen water/debris from the fall.
Make sure your gutter are properly pitched and have debris protection installed.
Make sure the Insulation company didn't fill the soffit/wall area full of insulation without baffles- This happens all the time!
Make sure you have properly install soffit venting installed.
