What are the reasons for my roof leakage and how to fix them?

Roof leakage can be a frustrating and potentially damaging problem for homeowners in Ontario, particularly during periods of heavy rain or snow. There are several reasons why a roof might leak, and the appropriate solution will depend on the specific cause of the problem. Here are some common reasons for roof leakage and how to fix them.

  • Damaged or missing shingles: Shingles can become damaged or worn over time, allowing water to seep into the roof. If your roof has damaged or missing shingles, water can seep through the gaps and cause leaks. To fix this issue, damaged shingles should be replaced, and missing shingles should be replaced or repaired. This can be done by removing the damaged shingles and installing new ones, or by patching the damaged area with roofing cement.
  • Clogged gutters: Gutters that are clogged with leaves, debris, or ice can cause water to back up and seep under the roof shingles, leading to leaks. To fix this issue, clean out the gutters and downspouts regularly, particularly in the fall and spring when debris is most likely to accumulate. Also make sure they are properly attached to the roof.
  • Faulty flashing: Flashing is the material that seals the seams and joints in your roof, such as chimneys or vents. If the flashing is damaged, improperly installed, or has deteriorated over time, it can allow water to penetrate the roof. To fix this issue, the damaged flashing should be removed and replaced with new flashing that is properly installed.
  • Poorly sealed roof vents: Roof vents are important for proper ventilation, but if they are not properly sealed, they can cause moisture to build up in the attic, leading to roof leaks. To fix this, make sure the attic has proper ventilation, including vents in the roof and eaves.
  • Ice dams: In the winter, ice dams can form on the roof, preventing water from draining properly and causing it to seep into the roof. To fix this, use a roof rake to remove snow from the roof and make sure the attic is properly insulated to prevent heat from escaping and melting snow on the roof.
