Winter season can be hard on your housing structure. Ice, snow, and blizzards can cause the roof area to freeze and thaw continuously creating roof problems and costly roof repairs. Another primary reason for roofing Calgary damage can be flashing leaks. Sloped roofs can pull or damage the flashings that are strategically placed along the corners and front parts of your roof. If they are not installed correctly, it can lead to heavy leaks. You should inspect flashings every 6 to 7 months to forbid such flash leaks.
