Winter Roof Damage




In case you haven’t heard yet, winter is coming! Batten down the hatches, fire up your heater, and get out your warmest coat!

One thing a lot of people don’t think about when it comes to winter is the potential damage the cold season can do to your roof.


Heavy hail can create more than just some dents that are an eyesore to look at. Hail can cause hairline fractures and punctures in your roof. Often times, they do not appear for a while, but when they do, you will have a big problem. The small cracks can allow water under your roof, but not completely into your house, leaving it trapped in-between. If you live in an area where large-sized hail is common, you may want to look into investing a cover board over the thermal insulation of your roof.

Understanding how to care for your roof in the winter will save you thousands.

Snow & Ice Accumulation

When snow builds up in certain areas of your roof, it can cause weight distribution issues or damage other roof components such as roof flashings and tie-ins to other aspects. These build ups can happen where the roof connects to a wall or where there are lower roof areas such as awnings or sun windows. When temperatures hover around the freezing point, it can be very damaging! When water gets in a crack or a small area and freezes, it expands. This will happen repeatedly throughout the course of a winter. Unfortunately, there is not much we can do about the freezing and thawing here in the Midwest other than make sure you’re maintaining your roof regularly.

Ice Dams

Ice dams are ridges of ice that form on the edge of your roof. When these form, water backs up on your roof and has no where to go except under the shingles, which can lead to intrusion into your home’s ceiling and inside walls. Ice dams also have a hand in the wear and tear of your windows and siding.

Until winter is behind us, there is not much you can do about all these winter weather issues except keep an eye out for problems and be proactive with repairs. Check your windows and ceilings throughout your house for drips or stains, and don’t forget to look in the garage and closets! If you notice that any of these repairs are needed in your home and would like more information, don’t hesitate to give J-Tech Construction a call!
