How Does Ice Damming Lead to Mold?

2/20/2018 (Permalink)

Ice damming is a problem in climates that receive a lot of snow. If the attic of a structure is not property ventilated and the gutters are clogged, ice and snow on the roof will melt, run down and refreeze around the edges of the roof. Over time, this backed-up frozen and refrozen precipitation or ice dam can cause leaks through shingles that trickle behind the walls of a structure. These leaks can cause water damage and promote the growth of black mold.

Here are three ways to prevent ice damming:

1. Adequately ventilate attic space.

Roof eave ventilation prevents ice dams from forming. Ventilation should flow from the underside of the eave through the attic and out near the top of the roof. The attic should remain cold and insulated from heat in the interior of the structure.
2. Clear the gutters. Snow and ice should slide off of the roof rather than accumulating and refreezing around the edges. Clogged gutters can cause ice dams and result in gutter and roof damage from the added weight.
3. Make sure that the roof is watertight and in good condition. The roof should be in a condition to withstand winter precipitation without admitting water into the structure.

If a structure in Clear Lake, TX, has already experienced leaks as a result of ice damming, contact a service that specializes in mold testing and cleanup as soon as possible. Leaks caused by ice damming can result in water damage and the formation of mold on drywall, masonry and in wall cavities. Mold can start to form between walls in as little as 24 hours.

Ice damming is a common cause of hidden black mold, as these leaks occur behind walls. Mold cleanup specialists can address extensive water damage and eliminate the risk of mold growth following a leak resulting from an ice dam.
