The Most Common Causes of Leaks During the Winter
In winter, water can leak more easily from homes that are not well-insulated. Ice dams may form. Condensation in exhaust vents can also lead to roof leaks. They are more likely to happen in bath vent ducts that run through unheated attics. However, despite the winter weather, there are a few preventable causes of leaks.
Flashing
The winter is particularly hard on flashing. Because ice and snow build up around the flashing, making it vulnerable to moisture seepage under the metal strips. This can lead to leaks in your roof. If you notice any signs of damage, it is time to get it replaced. A good contractor can handle the task. If you have a problem with your flashing, call them for help before it becomes widespread.
Ice dams
You've probably had to deal with ice dams if your roof leaks this winter. This can be a big problem for homeowners. Water can seep into your attic, roof, and walls, and you'll have perpetually leaky windows and doors. Not to mention mold growth. This kind of damage may even cause your roof to collapse! However, it's important to note that ice dams are typical "Acts of God" and aren't covered by most homeowners' insurance policies.
Clogged gutters
In addition to leaking, clogged gutters can cause damage to your home. They can't properly drain water, and this can lead to the formation of ice dams that cause pools of water. When standing water forms in gutters, it can damage siding and walls. The best way to prevent this problem is to clean your gutters regularly and use gutter guards to help keep debris from blocking them.
The attic that is not heated
A well-insulated house can prevent water from leaking into the unheated attic. Heating air from the furnace can leak into the attic during winter. This creates warm spots on the roof. The roof slope is heated by warm air, which melts the snow. Once it reaches a cold area, it refreezes and forms an ice dam. The resulting water then flows back up through the roof, causing damage to shingles and ceilings.
Cracked shingles
Although a few basic things will help prevent winter leakage, it is best to not do them yourself. Your roof's shingles can be damaged by weather conditions, fallen branches, and age. When they become damaged, rain and snow will seep into these holes and cracks, causing leaks. If you can afford it, hire a professional to do the work.
Failed chimney flashing
Failure to flash the chimney can cause winter leaks. Despite the fact that flashing is necessary to keep water out of a house, many builders struggle with installing it properly. Chimney leaks are a common reason for chimney and roof repairs. If the flashing is not installed correctly, water may enter your home and cause problems such as rotting wood.
