How to Prevent Ice Dams and the Roof Leaks They Cause

Here we are in the middle of another Massachusetts winter and like every winter in New England many property owners will have major problems with roof leaks and shingle damage due to ice dams.

Although it seems that ice dams are an unstoppable force of nature, they are actually restricted. Attic and cathedral or vaulted ceiling areas that are properly incorporated into the entire building envelope do not have problems with ice dams and icicles during the cold season. Ice dams can be stopped cold (pun intended) by using proper insulation and ventilation techniques.

Here is a typical scenario for the formation of ice dams:

  1. There is snow on the roof of the house.
  2. The temperature outside is below freezing.
  3. Attic temperatures are above freezing, so roof temperatures are above freezing.
  4. Due to the warm roof, the snow above it begins to melt from the bottom up.
  5. This melt snow water tries to flow down from the roof.
  6. As water reaches the edge of the roof, it is exposed to freezing air.
  7. Water freezes as ice instead of ice in the gutters, if any, and on the edge of the roof.
  8. As more and more meltwater flows down the roof, it freezes back and forth behind the frozen area above, forming a larger and larger ice dam.

So how do ice dams cause roof leaks?

Melted ice water does not freeze immediately after an ice dam begins to form. Once the ice dam builds up a bit, it literally creates a dam that traps the rest of the water trying to run off the roof behind it. While this trapped water eventually freezes, it can take a while, and in the meantime, behind the ice dam, a portion of these roof shingles are basically submerged.

Now obviously your roof ornaments protect your home from the weather i.e. rain and snow. However, most roofing materials do not mean that they will have a lake or river above them.

So what can you do to prevent ice dams?

First and foremost we must recognize that proper insulation and ventilation is key (see image to the right). If we are talking about the attic area, this means that the insulation has to go up the walls of your house and then create an ideal insulation envelope on the attic floor. In attic situations only the attic floor should be insulated, not under the roof!

Proper ventilation is also essential. Outside air must be able to enter the attic so that The attic temperature is the same as the outside temperature. You achieve this ventilation through the use of gable vents, soffit vents, and roof ridge vents.

In roof systems with attics below them, it’s pretty straightforward to have a contractor who knows what they’re doing to eliminate any problems with proper insulation and ventilation. However, it is more of a project to improve cathedral ceiling systems with these problems, but they can be fixed.

To have a properly ventilated and insulated cathedral ceiling the contractor must install baffles in each rafter bay before installing the insulation. These baffles allow air to flow into the soffit vents and ridge vents that keep the outside temperature equal to the underside of the roof. If your cathedral ceiling does not have metal baffles installed, the contractor will need to remove the existing sheetrock and insulation from your ceiling to properly ventilate the area. This type of project will be more expensive than an attic project.

In addition to the ice dam problem, if your attic is warmer than the outside temperature, you’re wasting a lot of money heating the space. So basically you’re paying extra on your heating bill for the privilege of creating nice big ice dams and roof leaks and destroying your roof. It makes it worse when you think of it like that, doesn’t it?

What can you do about existing ice dams?

If it’s the middle of winter and you have ice dams, or from past experience you think they will form soon, there are some measures you can take. First of all, if you don’t have experience climbing a roof in winter, especially with snow, don’t do it! Call a pro. What you can do is go to your local hardware store and buy a snow rake that has an extendable handle designed to pull the snow off the first few feet of the roof, and try to get some snow off the ground first. There is a chance of thawing and freezing at the edge of the roof. You can also do this once the ice dam has formed and prevent it from getting bigger and give it a chance to melt, hopefully.

Also, many roofing contractors, including us, work in the winter and often offer roof snow removal services in addition to their typical roofing services. For example, this is a service we are happy to provide for our customers here in Massachusetts. Again, please do not try and do this yourself. Between the icy ladder and the slippery roof surface it’s a recipe for disaster for the inexperienced.

There are also products on the market that can help prevent ice dams before they form and melt them if they do form. You should be able to find a home improvement store in your area that basically sells a coated, heated wire product that you tie to the edge of the roof and then plug in when conditions are right to create a snow dam (see picture at right). These actually work very well, however, they do not solve the real problem which is of course ventilation and insulation problems. They may be suitable for some homes in some situations.

Most home improvement and hardware stores also sell pellets or pellets designed to be thrown from the floor to the ceiling. These pellets will then supposedly melt the snow on the roof as it dissolves in the water flowing from the roof into the ice dam. I don’t have experience with these products so I can’t say for sure if they work as designed. However, some people say it has worked for their ice dam problems. A few things I would be concerned about as a roofing contractor are the potential damage to the shingles from the chemicals these pellets are made from (salt is not good for asphalt shingles), as well as staining the roof from those same chemicals. And even in a base case scenario, this product is just a Band-Aid for a bigger problem.

Proper roofing techniques for cold climates

In addition to ensuring that the roof has proper ventilation and attic insulation, there is an additional level of safety against ice dam problems and roof leaks that all responsible and ethical roofing contractors should take with regard to pitched, asphalt roofs in cold climates. . When a new roof is installed, these days, an additional layer of protection called a snow and water membrane must be installed at least 3 feet above the roof.

This added layer of protection will help prevent leaks if ice dams build up on the edge of the roof. A snow and water membrane will not prevent ice dams, it only adds safety to protect the plywood sheathing under the asphalt and prevent leaks if an ice dam forms.
