The most reliable way to stop ice dams from forming on your roof is to keep your roof cold and avoid uneven temperatures on it.

Even though it may seem that the winter, snow and freezing temperatures will do that part themselves, sometimes it is not as simple as that.

The attic below the roof and the temperatures inside your home play a big role in maintaining even temperatures across the roof and keeping it cold enough.

Read on to find out how and learn what you can do to prevent your roof from warming up and ice dams from forming.

Add Attic Insulation

A great way to prevent the heat from your home and attic from transferring to your roof is to add insulation to the attic.

In addition to that, it has also proven very useful to add insulation into the ceiling just below the attic or the attic floor. This will further decrease the heat transfer from the lower parts of your home.

The warm air will then not be able to reach the roof deck, warm it up, and cause the snow to melt, which would eventually lead to ice dams.

If you already have attic insulation in your home, then check and seal any gaps and cracks in it, as they can also let warm air escape to the roof.

Install Attic Ventilation

Attic ventilation is an integral part of your roof that not only prevents ice dams from forming but also protects your entire roof structure year-round and preserves its health and stability.

Quality attic ventilation allows the air to circulate naturally in the attic space and just below the roof deck, keeping the temperatures optimal.

This means that during winter, the cool air will circulate around the roof, keeping it cold and below freezing, matching the outside temperatures and preventing the snow on the roof from melting.

Make sure to have your attic vents professionally inspected and repaired if needed so that they can do their job and keep your roof healthy and ice dam-free.

Repair Any Cracks in the Ceilings and Attic

Homes tend to lose a lot of heat through various cracks and gaps in their ceilings, walls, and attics. These cracks can lead to both the roof heating up too much and the energy bills increasing significantly.

Therefore, if you are faced with unusually increased bills and ice dams are continually forming on your roof, make sure to check your home for these cracks.

They are usually found around the light fixtures on the ceilings, around the piping, chimneys, and any other penetrations on your ceilings and walls. 

There can also be some gaps in your attic insulation or cracks in other parts of your attic, roof deck, and similar, which would allow the heat to escape to the roof.

Remove Snow from the Roof

When there is no snow on the roof, there is nothing to melt, which means no ice dams can form.

Therefore, when snow accumulates on the roof or when there was a big snowstorm, make sure to rake that snow off the roof as soon as you can because ice dams can form very quickly.

There may also be some parts of your roof that you simply cannot keep cool enough, so the best solution is to make sure there is no snow.

However, removing the snow can be a risky task, so make sure you are always safe or call in a professional to do it for you.

Final Thought 

Maintaining your roof cold enough will help you avoid the formation of ice dams during winter as well as prevent all the dangers that come with it, such as leaks and damaged shingles.

Therefore, make sure you have quality insulation and ventilation installed in your attic as well as that there are no gaps and cracks where heat can escape.
