Ice Dams and leaking roofs in the winter Since it is snowing here in Cincinnati, I thought I?d write a quick article on Ice dams and the possibility of leaking roofs. Ice dams form when snow melts either from the top of the roof (from sunshine), or warm air from the house enters the attic and melts the snow from the underside of the roof decking. When the water runs down the roof like it should, it can re-freeze along the way, and build up as a dam that traps the water and prevents from going down the shingles (or slate or wood shakes) to the gutters and down and away from the home. This ice buildup creates a pool
Furnaces come in 3 types of efficiencies. Low, mid and high. The lowest efficient furnaces are typically 40 years old or more. You?d be surprised how many of these are still in use in homes. I live in Cincinnati, former home of Williamson furnace company. You can identify a Williamson furnace, because they are typically green in color, and are roughly twice the size of a newer furnace. Williamson?s and other furnaces of this ilk, are considered very inefficient by today?s standards. They have standing pilot lights, no draft induction motors or dampers inside the flue pipe, and are often times over-sized for the square footage of the home. The efficiency of this type of furnace is probably less than
