What are Ice Dams caused by?

As heat rises from a home, it melts the snow that has accumulated on the roof. That melted snow travels down the roof in liquid form until it reaches the eave line and gutter, where it refreezes due to colder temperatures. This ice ridge continues to expand, blocking the flow of the liquefied snow melt.

As water continues to melt higher up the roof, it collects behind the ice dam in the form of a puddle. Because that water sits over the warmer portion of the roof, it doesn’t freeze.

In order for ice dams to form, snow needs to build up on the roof, home heat loss, and subfreezing temperatures. The more snow, the larger the heat loss, and the longer the subfreezing temperatures remain, the higher the likelihood that ice dams will form.

What to do if you are suffering from the effects of one?

Homeowners suffering the effects of an ice dam, or those who fear a leak is forthcoming, can hire DRS to remove the ice buildup and to get the snow and ice off the roof. Once the leaking (and source) stops, mitigation and repairs can commence.  DRS will respond and help come up with the appropriate game plan that best fits your needs. Remember, exterior walls have insulation and vapor barriers that will require demolition in order to effectively dry out the water damaged materials and prevent mold.

If you or any of your clients suffer from ice damming or other water damage, DRS is ready to respond 24/7.
