Roof Flashing Failures
Roof flashing is not one of the most well-known parts of a roof. If you’ve never dealt with roof maintenance before, it’s possible you might not even know what it is. However, roof flashing is an important material for keeping your roof watertight and secure. Roof flashing is a thin layer of water-repellent metal that directs water away from spots on your roof that could be vulnerable to moisture damage. You can usually spot flashing connecting chimneys and vents to your roof, or sealing joints between the outside roof and wall.
When roof flashing fails, it can leave your home vulnerable to leaks, mold, and other forms of water damage. Learning to spot common roof flashing problems can help you get repairs done before the damage takes place. So, what should you be looking for?
What Causes Damage to Roof Flashing?
Like any other part of your roof, roof flashing is made to go the distance. That being said, there’s no such thing as a maintenance-free roof. While roof flashing is typically very durable, there are conditions that can cause it to be damaged to the point of ineffectiveness:
- Old age. This is one of the reasons it’s important to learn everything you can about a roof before you take ownership of a building. Even the best roof flashing will eventually start to fail. Be sure to look at your building plans, roofing warranties, and all other roof documentation so you know what to expect.
- Harsh weather. High temperatures can cause the metal roof flashing material to contract and expand, resulting in wrinkles and imperfections on the flashing surface that can cause leaks. Flashing can also be damaged by hazardous weather like hail and high winds, which can knock flashing out of place or even put holes in it.
- User error. One of the reasons you want to work with a professional when having roof flashing installed is that if it’s done incorrectly, the flashing can pull free and will no longer protect the parts it’s supposed to keep safe.
- Settling foundation. In some cases, cracks and warps in roof flashing can indicate issues with the foundation of a home. An experienced roofer will be able to advise you if that’s what is occurring.
What Signs of Damage Should I Be Looking For?
Roofing experts recommend that you get your roof inspected at least once a year for any needed maintenance. While that inspection takes place, it’s a great time to give your roof flashing a little extra attention. If you see any of these signs of damage, it might be time for a roof flashing repair:
- Rust, paint chips, or other evidence of surface damage
- Large or small holes in roof flashing
- Missing sections of flashing, especially after hazardous weather events
- Evidence of water damage on siding or shingles, indicating water build-up on the roof
- Evidence of leaks or water damage inside your home
If you see roof flashing damage, don’t try to fix it on your own. When it comes to roof flashing, the repairs are best done by experienced professionals. Make sure it’s done the right way the first time, and you won’t have to worry about your roof flashing again for a long time.
Now that you know how to spot common roof flashing problems, be sure to keep an eye on your roof, especially during periods of hazardous weather. The earlier you catch roof flashing issues, the better off you’ll be.
