Roof flashing is getting more popular these days. More and more residential and commercial building owners consider flashing their roof as an effort to protect their building from harmful weather conditions.

To protect your building from water that may seep into the building, you need to add an additional feature to your roof. In this case, the best solution is flashing.
What Is Roof Flashing?
Basically, roof flashing is a piece of sheet metal that is placed over joints in roof and wall construction. It is also commonly placed around chimney and plumbing vent stacks.

Because such joints are relatively lower than other parts of the roof, they are a favorite area for water. In fact, once the water seeps into your building, it can promote various problems including the development of mold and fungi. In most cases, it can cause leakage on the roof. By flashing the roof, homeowners can get rid of such worries. They can sleep soundly even though it is rain hard outside as they know that the flashing can combat the weather.

Roofing is not only about installing roof or choosing the right materials but also about giving full protection to the building.
