Because flashing is your roof's first line of defense against water, it is imperative that your flashing is perfect because water will always find its way in. Throughout the years flashing has been made from a variety of materials ranging from plastic, to rubber, and everything in between. But these types of flashing are not optimal. They crack easily and will then let water in. The best and only material you should be using is a rust resistant metal such as copper or aluminum. These types of metals won't crack and won't rust, offering your roofing the best possible seal and protection from water.
Many roofers will use a roofing cement to seal old flashing that is no longer protecting your roofing. However, this could not be more wrong. Roofing cement is a temporary fix and will ultimately lead to water damage. To properly seal your roof, old flashing that is leaking should be removed and replaced with copper or aluminum flashing.
Now that you know how important flashing is, you need to take the steps to make sure your flashing is protecting your roofing as good as it should be. Flashing is not expensive and when done correctly can help your roofing last longer. If you have had sub-par flashing repairs with roofing cement, or have plastic or rubber flashing, contact a professional roofer today. Even if there are no noticeable signs, there could be minor problems that will lead to bigger issues down the line. A few dollars spent today can save you thousands in the future.
