Winter Roof Issues

While winters in Georgia are mild compared to other places in the country, understanding potential roof issues that can emerge is a great way for homeowners to learn more information and stay aware of situations that come with a house. We highlight common winter roof issues in this blog post.


Condensation occurs when warm air and cold air meet. This commonly occurs in attics that have been warmed up alongside the rest of the house for winter months. When the warmer interior meets the cold underside of the roof during colder months, water builds up. This water buildup can lead to mold, mildew, and an overall bad smell in the home.

The best way to combat this is making sure your roof is properly ventilated. Keep the airflow going and try to minimize the amount of warm air coming in contact with your roof during the winter.


Roofs need flashing to help close the gaps between materials on the surface, closing off exposure that inner layers have to the outside. This is great for keeping out moisture and can usually be found around chimneys, vents, and pipes. These are susceptible to damage during the winter because of strong winds and ice.

To prevent leaks in roof flashing, the best thing you can do is inspect beforehand and make any repairs before the weather gets too bad. These are common problems if your roof if old and corroded or exposed to freezing and thawing. Take the offensive route by preparing ahead of time.

Weather Damage

We all understand that sometimes winters come with severe weather from storms to strong winds. These are all elements that can cause damage to your roof from adding moisture to completely peeling or ripping off shingles.

They can also affect external surroundings like trees and branches that can scrape or pierce your roof’s materials. The best course of action is to be prepared for severe weather so you can anticipate its actions. Inspect your roof often and keep tree limbs well-trimmed so that they can’t cause too much damage if they were to come crashing down.


Animals are excellent at finding the warmest hiding spots, especially when cold weather comes their way. Squirrels, bats and other small animals will use small gaps in your roof to invite themselves into the warm and safe environment of your home. Don’t underestimate them when it comes to tiny holes either. They have their ways of gnawing at roofing to get in.

Inspect your roof often and keep an eye out for potential points of entry.

Ice and Snow

On the off chance that we ever do get hit with snow and cold weather, ice dams and icicles will be another winter roof concern. Ice dams are formed when parts of the roof are warm enough to melt snow while others are still cold enough for the melted snow to refreeze. Icicles also form in a similar way and are caused by melted snow dripping down the roof.

These can all cause damage to your roof and gutters as well as leaks. To address this, you’ll want to remove snow and ice from the edges of your roof, keep your gutters clear of debris, and keep your roof ventilated and insulated.
