ICE DAMS

excessive ice dam

Ice dams in Massachusetts are an ongoing nuisance and are causing extensive damage to soffit cavities, fascia boards, roof sheathing, gutters, and to the most outer portion of living area walls. This ice build-up can absolutely be alleviated, but every house tends to have a different situation as to why this ice dam is there in the first place.

First, I'd like to explain how this massive ice mound forms on the most outer edge of your roof...

 

HOW ICE DAMS OCCUR

It snows and your roof surface will continue to accumulate this falling snow and the temperature (outside) of your home drops to below freezing.

1.) The temperature inside your attic is above freezing (warmer), due to the heated living area (below the attic) allowing heat to infiltrate the attic cavity, thus raising the temperature of your roofing material to above freezing.

2.) Because of the temperature differential and the warmer roofing material, the snow on top of the roof starts to slowly melt and gravity takes over. The melted snow (now water) starts to cascade down the roof (underneath all the accumulated snow) in an attempt to drain off the roof or into your gutters.

3.) As soon as the water reaches the outer edge of the roof (where the outer roof edge will not be as warm as the attic cavity) it gets exposed to the freezing air. The cascading water now freezes into an ice mound (that literally clings to your roofing material) along the edges of your roof and the gutters (if applicable).

4.) As more and more melted snow (water) continues to cascade down your roof, it continues to freeze behind and on top of the previously frozen run off, forming a much larger ice dam. Once this ice dam takes shape, it will literally trap any water that is attempting to drain down and off the roof. Now, all the melting water is dammed and has nowhere to drain to, so it builds up. This accumulating water is simply backing up and is forced right under your roofing material and into your attic or soffit cavity (and then gravity takes over once again), and this water infiltration simply drips down into your living area wall cavities, causing the nuisance staining and damage that may be observing throughout your walls.

When the heavy snow on your roof field becomes excessively uneven, this is indicative of heat infiltrating your attic and melting the snow on your roof, in turn causing ice dams.

Preventing this ice from forming on the edge of your roof in the first place is absolutely preventable. Many homeowners are continuously researching articles on “HOW TO PREVENT ICE DAMS” and they learn that proper insulation and ventilation is necessary to prevent these ice dams. That’s fine, but after most homeowners obtain their education on “HOW TO PREVENT ICE DAMS” they may attempt to correct their ice dam situation, but are still baffled and are unable to figure out exactly where any improvement is needed. That’s why they call me in to access their situation.

Your solution to alleviate your ice dam issues is the use of Infrared technology. My infrared inspection is a brilliant method of providing you with an instant snapshot of any active heat loss through the most outer portion of your walls and ceilings of your home. Deficient insulation is a poor insulator, which allows it to now become a great conductor of your conditioned air, and this is what enables me to easily detect the inefficient insulation applications throughout your home. Infrared imaging will visually show thermal mapping of any improperly insulated ceiling and wall cavities that are causing the ice dams at the outer roof edges of your building.

 

Take a look at the images below and see how easy Infrared detects uninsulated/problematic cavities where ice dams were occurring...

ICE DAM IMAGES COMBINED WITH MICE ACTIVITY IN THE ATTIC

The brown ice clinging to this particular siding is caused from ice dams at the eave area combined with excessive mice activity in the attic. The brown color of mice excrement mixes in with the ice accumulation (at the eave area) and when this ice starts to melt, the brown mess will seep out from the eave area and behind the siding material.

Note how this brown mess will follow the contour of the building.
