Types of Roof Leaks

Common Causes of Roof Leaks

Poorly installed or maintained flashing – Flashing is the material used to seal the edges and seams of the roof and is often made of aluminum or galvanized steel. If it is not installed correctly, or if it becomes warped or corroded over time, it can create a point of entry for water.

Clogged gutters – Clogged gutters can cause water to overflow and back up, leading to leaks in the roof and walls.

Missing or broken shingles – High winds, storms, and other weather conditions can cause damage to the roof. Missing or broken shingles can allow water to penetrate the roof and cause leaks.

Cracked vent boots – Vent boots, which are the rubber seals around the pipes that come up through the roof, can crack or get holes in them due to age and weathering. These can be a potential source of roof leaks.

Ice dams – Ice dams form when snow melts and refreezes on the roof. This can cause water to back up and leak into the roof, walls, and attic.

Identifying the Location of the Leak

  1. Inspect the roof for visible signs of damage or wear. Look for missing or broken shingles, cracked vent boots, or gaps in the flashing.
  2. Look for water stains on the ceilings and walls inside the house. This can help you narrow down the location of the leak.
  3. Check for water stains around windows, doors, and other areas where two different building materials meet.
  4. Look for water stains near the base of the chimney, vents, and pipes.
  5. Listen for the sound of dripping water in the attic. This can help you pinpoint the location of the leak.
