What are the Different Types of Flashings?January 20, 2020
The roofing of our property has been crucial to the overall protection of our home or building. It protects us from various elements such as harsh sunlight, extreme weather conditions, invasion of different animals, and so on. One part of the roofing system that is integral to its functionality is its flashing.
Roof flashing has been protecting properties from obtaining and accumulating water on top of the roof. Flashings are thin pieces of material that prevent water from passing into the structure. They also serve as a weather-resistant barrier system, decreasing water and other elements from penetrating the ceiling, chimneys, vent pipes, walls, windows, and door openings. With roof flashing, mould and other damaging problems to the property are avoided.
The materials that can be used in roof flashing are lead, aluminium, copper, stainless steel, zinc alloy, and many more. Roof flashings are usually incorporated in expansion joints to prevent any deformation due to expansion and contraction. With proper installation, the roof flashings should not stain, be stained, or chemically react by adjacent materials.
To date, there are three main types of flashing. These are typically used in roofing applications to increase efficiency and protection.
The most common type of roof flashing that is used in roofing applications is apron flashing. This type of flashing is popular since it can be used on almost all sides of chimneys, brickwork on flat roofs, or the meeting points of a roof and the brickwork of a structure. Moreover, apron flashing is also used in slate and tile roofs that meet a wall or a porch, on conservatory roofs, and around the bay windows. Its versatile nature makes it effective in covering almost all sides and types of the roof.
This type of flashing is installed on the edges where the chimney is connected to the roof so that it can prevent water and any other elements from entering the building.
Step flashing is applied in situations where a lower height roof runs into a wall, a roof meets a chimney, or a conservatory roof meets the wall of a property. The pattern for this type of flashing resembles the steps of a staircase that allows the lead to penetrate the courses between the bricks. This pattern helps the bricks prevent any damages and maintain pleasant aesthetics.
Roof flashing is vital to keep the water and other elements from entering and damaging our property. If you want to know more about roof flashings, you can contact us now at Jonda.
