During the colder months, ice dams can form along the roof edge. These are a build up of ice that can stop any water running away and draining properly. Ice dams can be hazardous to a roof, depending on the size and weight. Particularly big ice dams can even ruin a roofline and cause guttering to break away from the property. Ice dams generally form due to a lack of insulation in your roof space. Ice on a roof will normally melt and run off on a sloped roof, but the cold can cause any water to refreeze and create an ice dam. They can also potentially cause a blockage in the guttering, causing water to get stuck behind the ice. Any water that gets stuck can cause a leak that can affect the property itself and even the neighbours house. Due to the amount of water collected, it can do a lot of damage. The water collected won’t be clean either, due to mould and bacteria growing within it. If this gets inside your home, it could cause health issues due to the mildew spreading in the property.
By having the right ventilation and high standard insulation within your roof space, you can limit the chance of ice dams happening. Regular checks by a professional roofer will reduce the risks, due to being spotted faster and dealt with before any risks have time to advance. For all roofing materials in Barking, call us today.
