Ice Damming

Ice Damming in White Plains, Rye, Scarsdale and Greater Westchester County, NY


Watch this video to learn how ice dams form and how A NO Dealers, your local Dr. Energy Saver contractor, can help prevent them!

Ice damming forms at the edge of your roof and prevents melting water from properly draining off the roof. Since the melted water has nowhere to drain, it accumulates and re-freezes along the gutter system and in some cases may be so severe that leaks begin to seep through the attic. Severe cases have associated problems such as wood soaking, and damage to insulation, flooring/upstairs ceiling, and even stored valuables.

Dr. Energy Saver can help prevent ice dams from forming on your New York home by keeping the roof surface cold. A leaky attic will let warm air escape and melt uneven portions of snow on the roof - leading to ice dams.

Our professional insulation and air sealing services keep your attic the appropriate temperature to prevent ice damming on your roof.

Proper Attic Insulation Prevents Ice Damming

Ice dams are common whenever rooftop snow has had a day or two to melt and then re-freeze along the ridge of the roof. Telltale signs of ice damming include noticeably large icicles form at the roof's edge.

Once developed, water has nowhere to drain and can sometimes form pools that can seep into the attic space. When severe ice dams of this magnitude form, water damage may effect wall insulation, interior ceiling, and wall surfaces. Such ice accumulation outside the house can ruin gutter systems and even pose a safety hazard.

It's best to prevent ice dams before they become a serious problem. It's frustrating for any homeowner when a "perfectly good" home suddenly sustains hundreds or even thousands of dollars worth of damage from ice dams. However, once you understand the causes of ice damming you can properly address your home to help prevent ice dams from forming.

What Causes Ice Damming & Icicle Formation on Roofs?

A drop-down stair leading to an attic

If the access to your attic (attic hatch or drop-down stair) hasn't been well sealed or insulated, lots of warm air will leak up into this area. When large amounts of warm air leaks into the attic, more snow melts on the roof surface.

Snow accumulation - after a snowfall, snow accumulation on the roof will soon be warmed and begin to melt. Snow that melts in higher areas of the rooftop eventually re-freezes at the eaves, forming icicles, filling gutters with ice, and creating a "ridge" or "dam" that can channel melted water into the attic and living space.

A roof will heat up when warm air in your living space escapes up to the attic area. Build-ups of warm air in the attic will eventually find its way through any crack or gap and melt snow unevenly on the roof. The roof edge is where the melted water re-freezes and forms an ice dam. Sometimes, water freezes in the gutters, filling them with ice.

In other situations, the water freezes right at the edge of the roof before it even reaches the gutters. Either way, the resulting ridge of ice forms a dam that creates a reservoir of water. When this happens, it's only a matter of time before the water seeps beneath roof shingles and leaks into the attic.

How To Prevent Ice Damming & Icicle Formation on Your Roof

  1. Air Seal and Insulate Ducts:

    Ducts require particular care and attention. Your furnace may heat the air up to 100 degrees or more and send it through leaky sheet metal ducts through a 30 degree attic. It's inevitable that heat gets into the attic it's running through. Which means you get less heat delivered to the intended room; so you have to run the furnace more to keep your home heated - and that costs you money. Ducts must be sealed to prevent leaks in an attic, and insulated well to prevent heat loss (and heat gain in the summer).

    Attic vents are less necessary in an attic that is properly air sealed, insulated, and has its ducts taken care of properly. However, these vents will keep the roof deck very close to the outdoor temperature, since they don't have all the heat (and moisture) to vent out as they did before the home was "fixed."

  2. Air Sealing and Insulation:

    Air sealing should ALWAYS be done before adding home insulation in NY or anywhere for that matter. A contractor who wants to hastily blow insulation in an attic without air sealing first, is taking the easy way out.

    Proper air sealing is much more difficult and takes much more time on average than blowing insulation, because you can see the progress of insulation but air sealing is less difficult to notice. The insulator who blows insulation without air sealing first is committing malpractice and doing the customer a great disservice. Why? Now all those air leaks (can lights, drywall to stud seams, pipe and wire holes, openings around chimneys and duct chases, etc.) that need to be sealed are buried under a foot or more of insulation. They are very, very difficult to get to ever again.

    But won't insulation stop air leaks? No way. Insulation lets air flow right through it. It's like having a winter coat on with just the stuffing, not the nylon shell.
