Stop Winter Roof Damage

Are you seeing large icicles on the edge of your roof? Do you have a lot of snow covering your roof? If so, we can help! We can remove the ice dams or heavy snow loads from your roof so you don’t have to worry about leaks and damage anymore.

                      

What Are Ice Dams?



Ice dams form when snow on your roof melts and turns to water that runs to edges of your roof. Because the edges of your home are unheated overhangs, water becomes trapped behind the ice or snow. This water pools behind the ice dam and is able to work its way
under the shingles. When snow accumulates on a roof, a cycle of melting and refreezing occurs. Ideally, the snow would melt off the roof, enter the gutters, and flow to the ground. Or the snow would evaporate from the sun’s heat, and never really melt off unless the outside temperature rose above the freezing point. However, two key factors can interact to cause problems; the outside temperature and the temperature of the inside of your attic. 

The warmer your attic is, the more melt off that occurs at the roof surface. This melted snow would normally flow off the edge of the roof. However, under certain conditions, when the air temperature is very low, the water refreezes at the edge of the roof, where the interior roof surface is not being warmed by the attic. This refreezing gradually forms ice dams, a large area of ice that blocks the path of the melted snow.

Once this dam forms to a certain height, the melted snow that pools up behind it can suddenly leak back under the roof shingles and into your home. To prevent damange to your roof and home, removal of these ice dams is necessary.

                      

Ice Dam Removal

Ice Dams can be removed many different ways from your roof, however there is only one safe way, STEAM! Steamers melt the ice on the roof without harming your roof system and stops the leak. Steamers use far less pressure and water than pressure washers. Pressure washers will blast the granules off the the ashphalt mat of the shingles on your roof. Axes, picks, hammers, and chainsaws will only cause more damage to your roof. Certain salts applied to your roof are corrosive and damage gutters, grass, and plants. Steamers take cold tap water and heat the water up to approximately 300 degrees. The steam cut right through ice and snow piled on your roof. 

Ice Dam SteamingOnce we have the ice dam removed, we can inspect your home for potential causes of these ice dams. Because of the variety of architecture of homes in our area, there are many possible causes of ice dams. The design of your roof, its ventilation, and its insulation can be some of the factors that trigger ice dams.

Snow Removal

Heavy snow loads can be structurally stressful on your roof's decking. This snow might not only be over the weight capacity for your roof, but it can eventually turn into ice dams. Therefore, the best way to prevent ice dams is to remove the snow as soon as it lands.

Removing the snow from the roof can help slow ice dam growth, but it may not prevent it. Therefore, continued snow removal maintenance should be done as a preventative measure.

Removing snow from a roof using a roof rake.

To remove the snow, our team can get on your roof and shovel snow off or rake the roof from the ground with a special tool called a roof rake, depending on what is best suited for your roof. On very low-sloped or flat roofs, it may be best to shovel off all of the snow. On a roof with a greater pitch, removing three or four feet of snow above the roof line may be adequate to slow down the growth of the ice dam.

Our team will discuss what option may be best suited for your roof and work with you to accomodate your needs.
