Because flashing is your roof's first line of defense against water, it is imperative that your flashing is perfect because in nature, water will always find somewhere to go. Flashing is 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 aluminum or copper. These types of metals won't crack and won't rust, offering your roofing the best possible seal and protection from water.
Often MCAS Roofing sees other roofers using a roofing cement to repair flashing. They simply put the cement over the old flashing hoping that it will do the trick. However, this could not be more wrong. The roofing cement is strong, but the problem is that once the original flashing continues to break down, it will continue to cause leaks. It is like painting a new layer of paint on top of peeling paint. If you don't sand it down and start fresh, your repair job won't last long. 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.
The great part about using metal flashing is that it also looks great. You can match the aluminum or copper metal to your style of roof. It is just an added way to keep your roofing looking great!
