Window and roof leaks are common problems, but they can be found and fixed with the correct approach. Here are some of the most common causes of window and roof leaks, and how we fix them:
Common Causes of Window Leaks
- Worn-out sealant: Windows are sealed on both the outside and inside with sealant. Over time, the sealant will dry out, crack, and shrivel. The sealant should always form a smooth, clean seal. If water leaks around your window sill, the sealant is likely the problem. Another sign of damaged sealant is drafty windows.
- Damaged seals: Windows have rubber or silicone gaskets that seal the window and block out rain and moisture. These gaskets can become damaged over time from wear and tear, or from exposure to the elements. If a gasket is damaged, water will be able to seep into the window and cause a leak.
- Improper installation: Windows that are not properly installed can leak. This is usually caused by gaps in the sealant or gaskets, but windows can leak if they aren’t seated in the frame correctly.
Common Causes of Roof Leaks
- Damaged shingles: Roof shingles are the most common cause of roof leaks. Over time, shingles can become damaged from wear and tear, or from exposure to the elements. If a shingle is damaged, water will be able to seep into the roof and cause a leak.
- Improper flashing: Roof flashing is the metal or plastic that is used to seal the seams between the roof and other parts of the house, such as the chimney. If flashing is not installed properly, water will be able to seep into the roof and cause a leak.
- Damaged gutters: Gutters are designed to collect rainwater and direct it away from the foundation of the house. If gutters are not properly maintained, they can become clogged with debris and water will be able to back up and cause a leak.
- Poor attic insulation and venting: Homes in our area see their share of cold, snowy winters. If you have a lack of airflow into the attic when it’s covered in snow, heat leaking from your home into the attic can melt the snow on the roof surface, run into the gutter where it’s cold, freeze, then cause an ice dam. Evidence of this problem is the formation of large icicles hanging from your gutters, and water leaking into your ceiling and walls.
