Ice Damming Near Sterling, Ashburn, Reston

Prevent roof icicles & water damage with our insulation services

Watch this video to learn how ice dams form and how Comfenergy, your local Dr. Energy Saver contractor, can help prevent them!

Frozen gutters and icicles hanging from your roof eaves are tell-tale signs of ice dams. An ice dam on your roof can cause damage to shingles, resulting in water leaks in your attic and damage to drywall, furniture, and flooring inside your home.

While a roofing contractor can provide a temporary solution to your ice damming problem, Comfenergy can prevent future ice dams by sealing air leaks and improving the insulation in your attic.

What causes ice damming?

Melting snow & freezing water form ice dams

Ice damming occurs when heat from inside your attic warms the underside of the roof and causes snow and ice on the roof to melt. When the water hits the cold overhang and gutters, it will refreeze and form an ice dam and icicles.

As the ice builds up a dam near the eave, melting water and rainwater will puddle behind the ice dam, and can leak underneath roof shingles and into your home. A water spot on your ceiling is a sign of a leaky roof.

There are several factors that can lead to ice dams, including inadequate attic insulation, poor attic ventilation, and clogged gutters.

How to prevent ice dams

Chipping away at the ice on your roof can cause damage to your shingles. The best solution for preventing ice dams and winter roof leaks is to properly air seal and insulate your home. These upgrades will pay for themselves in fuel and electricity savings, as well as provide you with a more comfortable, less drafty home.

We offer all the solutions you need to prevent ice damming:

Frozen gutters. We specialize in attic insulation and air sealing improvements that can help prevent ice dams and roof leaks.

Seal & insulate air ducts

Ducts must be sealed to prevent leaks in an attic and insulated well to prevent heat loss (and heat gain in the summer). 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. This 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.

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 & attic insulation

Air sealing should always be done before adding insulation. In addition to preventing ice dams in the winter, attic air sealing can help solve other issues like drafty rooms, uneven temperatures, and high heating or cooling bills. Sealing leaks will help your attic insulation perform like it should. By insulating without air sealing first, air leaks (such as around can lights, drywall to stud seams, pipe and wire holes, openings around chimneys and duct chases, etc.) that need to be sealed will be buried under a foot or more of insulation.

We offer effective air sealing and a wide range of high-performance attic insulation options, including spray foam and blown-in insulation.
