Ice Daming Example in Pennsylvania

Ice damming creates more than just exterior damage to the rain gutter system, it also causes water to leak into the attic, soaking the wood, insulation, the flooring/upstairs ceiling, and even the valuables being stored up there.

Bolster-DeHart, Inc. can prevent this all from happening by keeping the roof cold -- by sealing air leaks and improving the attic insulation.

Attic Insulation Prevents and Removes Ice Damming

Ice dams are common wherever rooftop snow has a day or two to become the telltale "icicles at the roof's edge."

Once developed, water often seeps into the attic, soaking the wall insulation, interior ceiling, and wall surfaces. Such ice accumulation outside the house can ruin gutters and even pose a safety hazard.

Homeowners' stress becomes understandable when a "perfectly good" house suddenly sustains hundreds or even thousands of dollars worth of damage. However, once you understand the causes of an ice dam, you can take these few simple steps to avoid further damage to your home or structure.

What Causes an Ice Dam?

If there's an attic hatch or drop-down stair that hasn't been well sealed or insulated, lots of warm air will leak up into this area, causing more snow to melt on the roof surface immediately above.

In addition, the roof will always be coldest along the edge because it projects beyond the exterior walls, where heat from the house isn't available.

Ice dams begin with snow accumulation, closely followed by a warming rooftop and melting snow.

As we all know, the deeper the snow, the deeper the trouble. Snow that melts in upper areas of the roof 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 begins to heat up when the warm air from the lower living space leaks into the attic (view example to the right). The snow will begin to melt unevenly -- because some parts of the roof will be warmer than others.

In fact, 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

  • 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 room intended - 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 it's ducts taken care of properly; however, the ducts 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".

  • Air Sealing and Insulation:

    Air sealing should ALWAYS be done before adding home insulation in PA 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. But with air sealing you don't see so much of the work when you scan the attic, and with blown-in insulation you see a lot; so it looks like something substantial was done. The insulation contractor 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.
