Ice Dams on Roof | How to Prevent Ice Dams
The roof of your home can take on major water damage and even collapse during the winter season of New Jersey.
This is often the result of roof leaks causes by the buildup of ice dams, or the weight of snow after heavy precipitation.
ServiceMaster by Timeless has a few tips for homeowners on how on to prevent ice dams from forming on their rooftops this winter in the Morristown, Parsippany, and Wharton, NJ areas.
What Exactly is an Ice Dam?
An ice dam is a chunk of ice that forms on the edges or eaves of your rooftop.
This dam is caused by uneven heat transfer across the surface of your roof. This is typically a result of poor insulation or lack of proper ventilation in your attic or upper floors.
These ice dams can damage the eaves of your roof from their weight, or allow snow to melt in large puddles of water on the rooftop. This can lead to roof leaks and significant water damage.
The Best Way to Prevent Ice Dams
As mentioned, ice dams typically form because the roof is receiving too much heat from the attic or upper floor of your home.
This melts the lower layers of snow on the rooftop and allows ice dams to form on the eaves.
To reduce the heat transfer from your attic or upper floor to the roof, you can:
- Add more insulation to the attic or other upper floor areas
- Increase ventilation in these areas with fans or design changes
- Prevent any leaking sources of air flow to these areas
The goal is to cool the surface of the roof to prevent unwanted melting.
In some cases, you can even point a box fan toward the roof from the attic to quickly cease the melting effect.
How to Respond to an Already Formed Ice Dam
If an ice dam is already formed on the eave of your house, you can actually throw a sock up there to help the situation.
Throw a Sock Filled with Salt
Fill up a large sock or pair of pantyhose with rock salt and toss it up on your roof.
You want to the sock to land so it’s perpendicular to the ice dam and atop it.
The rock salt and shape of the sock will create a melted channel where water will run off your roof or toward your gutters.
