Icicles hanging on your roof may look aesthetically pleasing in snowy weather, but keep in mind that they are a signal of upcoming problems for your roof. When icicles begin to form on the edge of your roof, they become hard and create chunks of snow on the roof called ice dams. These ice dams can cause damage to your ceilings, walls and, other components that are attached to your roof.
So, What Exactly Causes Ice Dams?
Ice dams are formed due to heavy snowfall with freezing temperatures. The high indoor temperature of the house causes snow to melt that is above the roof, this melted snow slides on the edges of your roof and again freezes because of the freezing temperature and form icicles, that block gutters and, while gutters are blocked the water from melted ice enters the insulation of your roof, ceilings and, walls of your residence.
Let’s jump to few other reasons why icicles are bad for your roof:
The main issue with ice dams is moisture and excessive water which can create roof leakages as gutters are blocked by the ice as a result the water will find a way and penetrate inside the roof. This excessive moisture and water will also cause mold growth on your roof, ceiling, carpets, walls and, wallpaper. Growing molds can cause a musty smell, which can make difficulty in breathing.
Several issues arise from the excessive load of snow present on your roof, let’s start with gutters, gutters are supposed to drain water from your roof when these gutters are blocked by heavy snow then it doesn’t only cause blockage of water but the weight of that snow can cause tearing and losing of those gutters.
If your residential roof has shingles, then it is also a damaging factor for them because shingles tear and break from heavy snow and excess moisture will result in roofing leakages. It is important to note insulation of your roof, if it is wet then it’s of no use.
How to Prevent or Remove Ice Dams?
The best practice to mitigate this problem is to contact a professional roofing inspector and let them perform an audit on your roof. If you are interested in DIY, you can do it by putting a fan facing your roof to meltdown ice dams.
Make sure to check the ventilation of your house, so that there will be no heat loss. Don’t let warm air go into your attic because it will cause moisture in the sheathing of your roof.
NOTE: Don’t try to reach your roof in uncertain weather because you will damage the roof and cause harm to yourself because of slippery surfaces.
