English: Ice dam forming on a slate roof near ...

Cleveland, Ohio. Snow melt caused by attic heat loss and warming of slate roofing collects at roof eave to create ice dam. (Photo credit: Wikipedia)

I have to admit this past week was extremely crazy. My phone did not stop ringing for the past 5 days because of all the houses that got flooded because of the ice dams.   Homeowners starting to understand the importance of a good quality roof instead of a quick fixer upper. The money they saved on the roof replacement plus few more thousands to the repairs to correct the issues and maybe a new roof. Ice dams does not form on its own. It requires either direct sunlight or heat loss thru your attic to form ice dams. Proper ventilation is one of the issues. When the vents get covered by snow, it makes it harder to vent our or even does not vent out at all. When the hot air gets trapped in your attic if will push back thru the ventilated soffit and start to form ice dams along the gutters. Hot fumes will melt the snow and turn it into ice over night. Eventually it gets bigger and wider. Whenever there is a warmer day, snow melts and it polls up behind the ice dam. It wont take a long time until you can see it dripping from your ceiling.
Here is my advise to the homeowners, don’t try to save couple of hundred dollars during replacing your roof. Make sure drip-edge is installed along all the edges. Depending on the slope of your roof have ice and water shield installed at least 6 feet from the gutters maybe more if needed. And have the rest of the roof covered with felt/tar paper or anything similar.
When we replace a roof our minimum usage of ice and water shield is 6 feet. Regardless of what the slope is, it is our company policy install 6 feet of ice and water shield and 100% felt paper and of course maximum ventilation.
