The answer to 'how long does flashing repair last' is that properly installed flashing can last 10-20 years or more with proper maintenance. Flashing is the metal or plastic material installed around chimneys, skylights, and other roof penetrations to prevent leaks. When flashing is installed correctly and maintained, it can provide a long-lasting, weather-tight seal. However, flashing can become damaged over time due to exposure to the elements, improper installation, or poor maintenance, which can lead to leaks and the need for repair or replacement.
Regular inspection and prompt repair of any flashing issues is important to prevent water damage and extend the lifespan of your flashing. Homeowners should visually inspect flashing annually and after major storms, looking for cracks, gaps, or signs of deterioration. Calling a professional roofing contractor to assess and repair flashing is recommended, as improper DIY flashing repair can lead to further damage.
