The Cold Weather Benefits of Metal Roofing

Reuben Miller

With the winter season now upon us, homeowners frequently ask us about how a metal roof handles the two most damaging cold weather elements: ice and snow. In order to help homeowners better understand the benefits of metal roofing year round, including extreme cold and winter weather, we’ve shared some of the most common concerns and their answers below.

Snow on a metal roof

Will snow easily slide off of my metal roof, is there a chance it could freeze and pile up?

In almost every case, snow and ice slide right off of a metal roof in a clean sweep. For this reason, metal roofing continues to be a very popular roofing choice in even the coldest and snowiest of climates, including the very cold regions of the US and Canada.

Fortunately for the homeowner with a metal roof, the destructive effects of ice damming — when snow backs up against your roof eaves and forces water into your home under the shingles, will never be a concern.

Because metal roofing is so durable and is designed to efficiently shed snow and ice, you’ll also be free of worry in regard to icicles or ice buildup that can damage or even destroy your gutters.

Which brings us to our next question…

If snow and ice shed from metal roofs so easily, what prevents large and potentially dangerous chunks from falling onto nearby walkways and traffic areas?

In addition to the beneficial design of metal roofing which allows the shedding of snow and ice, it can also be installed with snow guards or heating cables. Both of which will help to break up large snow and ice chunks to avoid the “avalanche” effect that might otherwise occur in extreme cases outside your home during the winter.

One important consideration when it comes to this issue is where whether or not you have heating sources within your attic could cause ice on both metal and asphalt roofs by melting snow in one area and allowing the runoff to re-freeze in another.

We recommend that you strategize with your metal roofing contractor to locate any heat sources within the attic of your home. Once these heat sources have been identified, you’ll be able to tailor the installation of your new metal roof so that snow and ice shed easily and safely.

Is it possible to install a metal roof during the winter months in a snowy region, such as Ohio in the middle of January?

Metal roof installations are not at all uncommon even during the most brutal winter seasons. This is especially because a heavy winter snow can be the breaking point for an old roof that needs to be replaced. In many cases the winter weather will make for a more difficult installation, but it by no means makes them impossible to install.

The bottom line is that regardless of what time of year it is, there are wonderful benefits to investing in a durable metal roofing system. Homeowners who have invested in a metal roofing system, can rest assured that whatever this winter has in store for them, their home’s roof can stand up to it with ease.
