Ten Winter Roofing FAQ
By Dymon Brady
Q: What flat roofing materials are best for areas with heavy snow?
A: If you are looking for a roofing material for a flat or low sloped roof that will be able to last through the toughest winters, a thermoplastic membrane is your best option. We specializing in installing TPO, a thermoplastic membrane, that is less likely to wear throughout the winters, or become brittle and crack. Asphalt based products are satisfactory, but they do break down in the freeze-thaw cycle, which is generally how they falter in cold winter climates. To learn more about TPO, see our post.
Q: What pitched roofing materials are best for areas with heavy snow?
The most popular material for areas with heavy snowfall is traditional asphalt shingles. Not only are they affordable, but they are durable and can withstand both hot and cold temperatures. Cedar shakes are also good, but are expensive and do not typically come with a warranty. Metal can be great in snow, but metal roofing isn’t as popular on residential homes. Keep in mind, If you are more concerned about staying warm in the winter than staying cool in the summer, you can choose dark shingles to absorb sunlight and warmth.
Q: Can I reroof my home in the winter?
A: Yes! Some people worry that asphalt shingles will not seal properly in the winter. Though this can be a real issue with an inexperienced installer, a professional roofing contractor will be able to install the product in the colder temperatures and protect against issues with the weather. Actually, winter can be a great time to get a new roof. Roofing contractors usually have a smaller number of jobs in the winter, and as a result, may be able to help you in a more timely manner. It definitely costs less to install in the winter time.
Q: What are “Ice Dams”, and what can I do to prevent and / or remove an Ice Dam?
A: Ice Dams are formed when roofs with poor insulation warm the snow on the roof from the heat in the attic. The snow will melt, and then re-freeze at the edge of the roof where the attic is no longer heating the shingles. You can minimize ice dams by having proper insulation and ventilation, allowing air to enter at the eaves and exhaust at the ridge. To protect your home against leaks due to ice dams, be sure to have ice shield installed on your roof. Ice dams can be removed by a professional team with warm steam removal.

Q: What should I do to prepare my roof for winter?
A: Chances are, you roof has been designed to handle the different seasons and climates you live in. However, there are a few things you can do to ensure your roof isn’t needing attention once it is covered with 3 feet of snow. First off, every homeowner should quickly look over their attic ventilation system and insulation to identify any possible issues. If you would like an in-depth inspection done, call a local roofing contractor. Brady Roofing will give you an honest assessment of what problems may arise, and we will help you to find a solution at the best value to you.

Q: How can I safely access my roof during the winter?
A: The best answer to this question is to try and avoid getting on your roof. If you have an issue, leave it to the professionals. Steep slope roofs, if covered with any amount of ice, can be extremely dangerous. And flat roofs are deceptively dangerous as well, since they always have a slight pitch of at least 2/12 and are very slick when wet. But if you feel you have no other choice, we have provided some safety guidelines: Winter Roofing Safety and Roofing Safety Procedures.
Q: How do I keep snow from falling off of my roof?
A: When deep snow accumulates on a roof, large amounts may fall from the roof to the ground (or whatever else is in the direct path) below. This can be dangerous to both people and your property. If you are experiencing this issue, there are several types of snow retention systems available that can help to control the issue. Read our post: Snow Retention Systems: Do You Need One?
Q: Is there a snow retention system available for flat roofs, specifically TPO?
A: Because flat roof membranes are slick surfaces, it doesn’t take much for snow to slide down their low slope. If your business or home is experiencing problems with snow falling from the roof, you can look into our custom made TPO snow fences. Other contractors may make a makeshift snow fence from 2X4 planks of wood, but we have developed a system that is safer, more attractive and longer lasting. See TPO Snow Fence for more information.
Q: My gutters are overflowing and I have water and / or ice coming up over the sides. What can I do?
A: This is a very common problem, especially in areas with large trees throughout the spring and autumn season. Most likely, your gutters have become clogged. This is a manageable issue. Find a tutorial on cleaning your gutters here.
Q: What is ice shield, and do I need it?
A: Ice shield is a type of underlayment installed around problem areas of your roof to help protect against water and ice that may enter under the shingles, by an ice dam or other issues. Ice shield is an essential component of any home in Northern or Central Utah. Learn more from our post: What is Underlayment?
