Meteorologists never can’t provide a clear forecast for what type of winter we’ll be having in Chattanooga. For our part, we keep you informed so you can prepare your home or building from the snow and the cold weather. This time, we’re taking a closer look at the most common culprit behind winter roof damage: ice dams.
Dam That Ice
Ice dams typically form after heavy snowfall or precipitation and several days of extreme cold. These can damage or displace shingles, which could then cause leaks.
When snow or ice on the roof melts, it trickles down into the cold gutter and freezes, which creates a blockage, or a “dam”. The melting can happen even in cold weather when heat from the building reaches the roof.
As the blockage continues to enlarge, water and ice back up under the shingles and re-freeze, creating openings. The trapped water and ice then seeps through the roof, plaster, the ceiling then into the home.
How To Protect Your Roof
The best protection against ice dams is still prevention, but if it already got into the shingles or the gutter, break it up carefully but do not use anything sharp that may damage your exterior.
To prevent the snow and ice from backing up, keep the roof, gutters, and downspouts clear even before the snow falls. Keep the roof cold by ensuring warm air is not leaking into the ceiling and attic. Seal plumbing vents and electrical wires, and boost attic insulation.
It’s best to do repair or maintenance works on the roof before bad weather comes blowing in. Whether its for a home, small store, or a commercial building, we offer a range of services for all your roofing needs. Get in touch with us today for efficient services that deliver great results.
