So What Can You Do To Prevent Ice Dams?

First and foremost you must recognize the ventilation and insulation are the keys(see image on right). If we are talking about a loft area then typically this means that the insulation needs to run up the walls of your house then over the attic floor joists forming a perfect insulation envelope. In the loft scenario, just the floor of the loft should be insulated, not the underside of the roofing Bronx NY!

Good ventilation is also required. Outside air has to have the ability to enter the loft so that the attic temperature is just like the temperature outside. You achieve this venting through using gable vents, soffit vents, and roofing Bronx ridge vent.

In Bronx roofing company systems with attic areas below them, it’s quite straight forward to have a contractor who knows what they’re doing to correct any problems as far as proper ventilation and insulation. But, waterproofing Bronx systems using a cathedral ceiling beneath them which have these problems are much more of a project to fix, but they can be corrected.

These baffles allow air to flow through the soffit vents as well as the ridge vent which keeps the underside of the roof repair Bronx NY the same temperature as outside. If these baffles are not installed on your cathedral ceiling then the contractor will have to remove the existing sheetrock and insulation out of your ceiling in order to properly ventilate the area. This sort of project will be more expensive than an attic undertaking.

So basically you are spending extra money on your heating bill for the privilege of developing nice huge ice dams and icicles which cause cement sidewalk repair and also ruin your  cement sidewalk. Kind of makes it even worse when you think of it that way does not it?
