Ice Dams on Your Roof: How to Avoid Them

While it is the start of summer, we can be certain that winter will return. If you plan ahead for your roof, you’ll be ready for the harshest winters Utah has to offer. That is why, when installing roofs in climates like Utah, we must be mindful of the risk of ice dams. When heat from inside a home or attic warms the roof and melts the snow on it, an ice dam forms. The melted snow runs to the cooler eaves and gutters, where it freezes again. Ice dams are formed as a result of this operation. Water backs up under the roof shingles or behind the fascia boards as a result of these dams, causing damage to your home both inside and out. Leaks caused by water backing up behind these ice dams are not covered by any shingle manufacturer’s warranty. To get more information try out here roofer

The good news is that ice jams can usually be avoided by following a few easy measures. Insulation, ventilation, and waterproofing shingle underlayment are the three methods for preventing ice jams in your house. To protect your house, you must take all three of these steps. Insulation reduces the amount of hot air that enters your attic by minimising heat loss from your home’s living room. This is necessary to keep you warm as well as your roof cool throughout the winter. Ventilation helps to keep your roof cool by removing heat from beneath it and preventing the freezing and thawing process. Finally, waterproofing shingle underlayment should be added until the shingles are applied to your roof. In the event of an ice dam forming on your roof, this will cover it.
If your roof is in good shape and there are no major issues, you will still want to protect it from ice dams. You can’t put waterproof shingle underlayment on an existing roof unless the shingles are removed first or a new addition is built. In your attic, however, you can increase the R-value, or degree of thermal resistance, of your insulation. In addition, adding ventilation to your attic at any time is usually easy.

When it comes to protecting your home from ice jams, insulation is a great place to start. If your house was constructed before 1980, you’ll almost certainly need more attic insulation. The amount of insulation your home needs varies based on where you live, how it was made, and other factors, such as your lifestyle. You should have a ceiling R-value of R-49, a wall R-value of R-19, and a floor R-value of R-25 in northern Utah. Depending on the material, one inch of insulation can have an R-value ranging from 3.8 to 4.2.
Both in the winter and the summer, proper ventilation is important for your home. Any heat that escapes your home is drawn out of your attic through ventilation, keeping your roof deck cool. This avoids ice jams in the winter. Any moisture from bathing, cooking, or washing will escape through attic ventilation rather than sit and mould or rot your ceilings. A mechanical ventilation system and a natural ventilation system are the two most common forms of attic ventilation. A power ventilator is an electric fan mounted on the roof or gable that is controlled by a thermostat to maintain the correct temperature on the roof. A natural ventilation system in your attic consists of simple vents or covered openings. Usually, these are mounted in your roof.
