Chimney flashing is an important component of your roof’s construction for many reasons, including the creation of a watertight seal between the chimney and the roof.
Like your roof, however, flashing may deteriorate and need repair during its lifespan, and proper maintenance protects both your roof and your home’s interior.
1. How Does Flashing Deteriorate?
Flashing is a sheet of metal or similar material installed in the area where the chimney meets the roof. As mentioned, one of its most important roles is to help keep water out of the home.
But chimney flashing can wear out over time for a variety of reasons, including these:
- Weather damage
- Improper installation
- Dents and separation
2. How Long Does Flashing Typically Last?
With proper installation, regular inspection, and consistent maintenance, chimney flashing can last up 30 years. But the longevity of flashing depends on many variables, including where you live, the type of material used, the size of your roof, and the type of roof shingles you have.
3. Can Anything Make Flashing Age Faster?
Many factors play into how long chimney flashing may last, including climate, weather damage, and cracked sealant, which blocks water from entering your home between the chimney and flashing.
Another issue is water damming at the chimney, which can occur when shingles are installed incorrectly. In this case, water dams up behind the chimney and begins to seep into the home.
4. Can Proper Installation Make Flashing Last Longer?
Installation problems not only cause leaks around your chimney, but hasten the deterioration of its flashing. Chimney leaks are often the result of faulty installation, which allows moisture to penetrate your roof’s inner structure. In turn, water seepage can cause mold, mildew, and shorten the lifespan of your roof.
5. Why You Should Use an Experienced Contractor For Flashing Repair
Chimney flashing repair and installation are challenging and best left up to the professionals. An experienced, knowledgeable roofing contractor will use proven chimney flashing techniques and make sure that any repair work prevents water leaks in the present and future.
