Flashing is usually built out of metal but can contain zinc, copper, steel, aluminum, and even plastic or rubber. Flashing is used to keep roof components waterproof and prevent any damage. Without flashing, roof components may come into contact with water that can saturate leak and damage the component or the structure of the house. Roof flashing keeps the integrity of your home intact.
Roof flashing installation occurs throughout your roof including all of the following places:
If you have ever noticed that there any leaks coming from around your chimney or vent most likely your flashing was not installed correctly or is no longer sufficient.
The main purpose of roof flashing is to protect your home from moisture and saturation. The flashing extends below your roofing and adjacent to the siding to create a solid, weatherproofing seal on your home to protect you from the elements.
So when having your next roof inspected or installed be sure that your flashing is properly installed by your local roofing contractor to ensure the best protection for your roof.
