Flashings on a roof-any issues that may arise over the course of home ownership

Flashings on a roof are essential components that help to prevent water from penetrating the roof and causing damage to your home. Flashings are typically made of metal, such as aluminum or steel, and are installed around roof penetrations such as chimneys, vents, and skylights. While flashings are designed to last for many years, there are several issues that can arise over the course of homeownership that may require repair or replacement.

1. Corrosion

Over time, flashings can become corroded, particularly if they are exposed to saltwater or other harsh elements. Corrosion can weaken the metal, causing it to crack or break, which can allow water to penetrate the roof. If you notice rust or other signs of corrosion on your flashings, it's important to have them inspected by a professional and replaced if necessary.

1. Improper installation

Improper installation of flashings can also cause issues with your roof. If the flashing is not installed correctly, gaps or spaces can be left where water can penetrate the roof. This can be a problem if the flashing was not installed with proper sealant or if there are gaps between the flashing and the roof.

1. Damage

Damage to the roof or flashings can also cause issues over time. Hail, wind, and other weather events can cause damage to flashings, leading to leaks and water damage. It's important to have your roof inspected regularly to identify any areas of damage and have them repaired as soon as possible.

1. Age

As flashings age, they can become less effective at preventing water from penetrating the roof. The sealant used to attach the flashing to the roof can break down over time, leading to gaps or spaces where water can enter. If your roof is more than 20 years old, it's a good idea to have your flashings inspected and replaced if necessary.

1. Tree damage

Trees can cause damage to your roof and flashings over time. Falling branches or limbs can damage flashings or even puncture the roof, leading to leaks and water damage. Overhanging branches can also scrape against the roof, causing damage to the flashings.

1. Wildlife damage

Wildlife can also cause damage to your roof and flashings. Squirrels, birds, and other animals can chew through flashings, causing gaps or spaces where water can penetrate. They can also build nests on your roof, which can trap moisture and cause damage over time.

In conclusion, flashings on a roof are essential components that help to prevent water from penetrating the roof and causing damage to your home. Over the course of homeownership, several issues can arise that may require repair or replacement of flashings. It's important to have your roof and flashings inspected regularly by a professional to identify any areas of damage and have them repaired as soon as possible. By taking care of your flashings and roof, you can prevent water damage and extend the life of your home.
