Your roof is in good condition when temperatures are between 70 and 80 degrees Fahrenheit (between 21 and 27 degrees Celsius). If temperatures drop below 40 degrees Fahrenheit (4 degrees Celsius), the roof will experience some damages. Most of the roofing materials feature adhesive products that need the heat from the sun for activation. Without the sun, the materials might start to break down. Even worse, the roofing material warranty becomes void when temperatures drop below 40 degrees F. Here are more damages that occur to the roof during winter.
Formation of Ice Dams
Winter temperatures lead to formation of ice dams. This is one of the main challenges of winter to the roof. The dams form when the temperatures in your home cause the ice on the roof to melt. The melted ice flows to the edge of the roof where it freezes again. The frozen water creates a dam that makes it challenging for any other water that melts to flow off your roof. This may cause the gutters, shingles, and eaves to break down. To ensure this does not happen, you need a well-ventilated roof where warm air leaves the attic and cold air comes in.
Condensation in the Attic
Without proper ventilation, there will be moisture and condensation in the attic. The warm air that rises from your home comes to the cold roof and then it condenses. You can avoid this by having a metal roof or ensuring there is proper ventilation. Moisture can cause so much damage to the roof that you will need extensive repairs.
Ice and Water Stress
If there is a lot of ice, snow, or water on your roof, the roof may be stressed. If the weight of the ice surpasses the load-bearing capacity of the roof, it can lead to cracks on your windows and doors. The ceiling may also bow, and in severe cases, the roof might collapse. You will see challenges, such as roof leaks, ice damming, and several water damage issues.
During the cold season, wind is also common. Window can loosen, break, or remove shingles from the roof. You need quality shingles for areas prone to heavy winds during the cold season.
You need to proof your home against damages from cold weather. For starters, get good quality materials and then contract the best roofing contractor for the job. The best roofer will ensure sufficient ventilation and other roofing factors.
