What You Should Know About Insulation and Your Roof

When it comes to the comfort of your home, what you do on the inside is just as important as what you have on the outside. Of course, a solid roof and siding will protect you from external factors, but between the rooms below it and your roof lies another space that you should also consider. 


Your attic is vital in maintaining a comfortable environment for the people in your home. Not only does the insulation in your attic keep your home comfortable, but it also helps maintain the integrity of your roof. At J Ferg, we know that maintaining the insulation between your roof and home is essential to maintaining a quality roof. 

How Does Attic Insulation Benefit My Roof? 

Ice Dam Prevention

A home that isn’t adequately insulated will allow heat to continue to rise through the ceiling, which warms the roof. During the winter, this can be problematic as colder temperatures bring snowfall. When snow accumulates on a roof that isn’t adequately insulated, it melts and drips down to your gutters and eaves. Because warm air rises, these smaller parts of your roof may not hold the same temperature as your roof, and the melted water can refreeze here if temperatures drop. This is called an ice dam. Ice dams are bad news for homeowners because they promote leaks and damage to your gutter systems. 


Ensuring that your attic is properly insulated will help eliminate the possibility of ice dams occurring by keeping your roof’s temperature levels controlled and less dynamic in the colder months. 

Condensation Prevention: 

Not all condensation occurs where it’s visible. For example, interstitial condensation occurs when warm air meets cooler air, creating water droplets that can damage your roof. This is problematic during the cooler seasons when the warm air inside your home warms your roof and meets the cooler fall or winter air outside. 


Ensuring that your home is properly insulated will help to trap the warm air inside of your home and restrict it from rising so far that it starts to warm your roof. Interstitial condensation is not a problem any homeowner wants to face. 

Shingle and Gutter Longevity

If your attic is adequately insulated, you won’t have to worry about condensation or ice dams around your roof. Proper insulation will save the roofing materials under your shingles and help to increase the longevity of those exposed materials. Your shingles and gutters won’t have to deal with frequent changes in temperature or the excessive weight of ice dams. When ice dams occur, your gutters and shingles may begin to loosen with the stress. 


Keeping your attic properly insulated is essential for all aspects of your roof. To help your roof and gutters last for years to come, ensure that you’re doing your part inside your home as much as outside.
