Snow and ice can damage your roof, clog gutters, and hinder drainage. It is vital to remove excess weight to avoid these problems.
Piles of snow that fall off a roof can also damage property and lead to serious injury. A snow retention system helps to keep your roof and the surrounding area safe by keeping piles of snow in place.
Prevents Damage to Your Roof
While snow might look light and fluffy when it first falls, it can quickly become a problem for your roof. A few feet of snow can weigh more than your roof is designed to handle, especially if packed.
Many homes in northern areas and high-snow zones are built with steeply sloping roofs, which help snow slide off the roof. However, if snow begins to build up, the roof can start to experience completely preventable damage.
One of the most significant signs that there is too much snow on your roof is strange noises, such as groaning and creaking. These can indicate that the snow creates pockets and an unbalanced load, which puts your roof at risk of structural damage.
Prevents Water Leaks
A snow roof system protects metal, slate, and shingle roofs from damage. These systems keep snow from shifting from the roof in heavy amounts, which can cause harm to people below and damage landscaping, parked cars, and lower or adjacent roof sections.
When ice dams form along the eaves, melted snow can become trapped behind them and seep under the shingles and into the building. It can lead to rot, water leaks, and staining in the attic, insulation, and interior walls.
Using a snow retention system keeps the ice dams from forming. It can be easily installed on both metal and shingle roofs.
Prevents Ice Dams
Ice dams are caused by warm attic air escaping through ceiling penetrations, such as wires, chimneys, light fixtures, plumbing vents, and knee walls. This heat melts the snow on top of your roof and then runs down the surface until it reaches the cold eave overhang, where it refreezes. This process builds a ridge of ice that prevents additional melting snow from flowing off your roof.
The trapped water eventually backs up under the shingles, causing sagging and stained ceilings, damaged gutters, wet insulation, and moldy walls and floors. It isn’t just an aesthetic problem. It can lead to electrical damage and health risks.
One way to avoid ice dams is to use a long-handled device called a “roof rake,” which scrapes the snow off the roof. But this is a labor-intensive approach, especially for single-story homes with steep slopes or homeowners who don’t want to climb on the roof.
Prevents Damage to Your Gutters
Heavy snowfall is not only difficult to remove from your roof; it can damage or even loosen gutters and their hangers. Ice dams and excess water can build up when these structures give way. This water can cause rot and leaks that affect other parts of the house.
A well-insulated roof that is free of escaping warm air is critical. It prevents pockets of warmer air from melting the top layer of snow. As this water trickles down the roof slope, it picks up additional snow and ice.
This icy mess is then frozen into the gutters, where it can clog and overflow. The resulting ice dams and overflow can damage the gutters, fascia, eaves, and other building components. A snow retention system keeps the snow from accumulating on the roof and protects other lower parts of the building from hazards.
Prevents Damage to Your Attic
After a snowstorm, checking your roof and attic for water damage is essential. Drips and puddles on your roof are signs of a problem that needs immediate attention to avoid costly repairs.
It’s also essential to look for physical signs of a heavy snow load, such as excessive deflection. Roofs are designed to withstand specific loads for their span length ratios, so when the structural members bend beyond the expected range, it could indicate an overload of live snow.
A roof snow retention system prevents the accumulation of snow that could cause a build-up of ice and water. The system controls the rate at which snow slides off a metal or shingle roof, providing an easy-to-maintain solution for your building. It’s also an effective way to add extra insulation to your home.
