Keep Your Energy Costs Low with Wind Ventilators
Roof flashing is an essential component of a roofing system that helps prevent water from penetrating into the interior of a building through joints or seams in the roof. It is typically made from rust-resistant materials such as metal, aluminum, or copper, and is installed at any point on the roof where two surfaces meet, such as around chimneys, vents, skylights, or where the roof meets a wall.
Flashing can come in various forms, including fabricated plastic, roofing felt, or rubber, but metal flashing is the most common due to its durability and longevity. Copper flashing is often preferred for its aesthetic appeal and durability, as it is resistant to corrosion and can last for decades.
The installation of flashing is critical to the effectiveness of a roofing system, as improper installation or a lack of flashing can lead to leaks, moisture buildup, and eventually, damage to the interior of a building. It is important to have a professional roofer properly install flashing to ensure the longevity and effectiveness of a roofing system.
