In order to keep your roof in good condition during winter, it's important to check for signs of damage such as missing or damaged shingles, loose flashing around vents, holes or cracks in the roofing material. Additionally, if you have gutters and downspouts, make sure they are properly secured and clear of debris so melting snow can flow freely without pooling on the roof which can lead to bigger problems down the line. Lastly, inspect your home for ice dams that may form along the roof overhang as these can cause water to back up and leak into your home. If any of these issues are detected, make sure to call a professional for repairs.
