Roof Flashing is one of the vital elements of the roof system. It helps in keeping the roof protected, waterproof, and airtight. It perfectly seals the outer case of the roof that helps guard the home internally from weather and other harmful issues. Make sure that the roof flashing is installed correctly. Follow a step-by-step guide if you don’t know how to install roof vent flashing. Roof flashing is needed around the chimney, skylight, dormers, valleys, etc. If these roof areas are not sealed properly during roof flashing, these areas start getting serious leakage issues. Once leakage issues start, this intersection will expand and tighten due to temperature. Thus, it is necessary to install good roof flashing to secure the home and keep the moisture away from the roof.
Material Used for Doing Roof Flashing
- Roof flashing can be made with different materials such as metal, copper, aluminum, lead, steel, plastic, etc.
- Lead is used for doing roof flashing in small areas which are difficult to maintain or replace.
- Metal is commonly used for roof flashing. It has various alloys which are also included in it such as steel, zinc, and aluminium.
- Although plastic is very cheap, it is not very long-lasting. However, it can be worn down anytime when overexposed to direct sunlight.
- Copper is a comparatively expensive metal but ideal for high-end homes. In addition, it can adapt to weather changes.
Different Areas of the Roof where Flashing is Required
While beginning with the installation procedure of roof flashing, ensure that you have selected the suitable material in terms of quality and durability, which goes well with the other roofing material. Choose flashing material after examining the roof. It will provide you with an idea about the requirements of your roof. Please don’t go for anything which is not suitable for it. For perfect roof flashing, it is also essential to be appropriately installed. Flashing helps in covering weaker areas of the flat and sloped roof from damage. Generally, it is applied along edges, walls, valleys, and chimneys. In addition, it acts as a water shielding membrane to block the roof from water leakage issues. Here are the different areas of the roof that demand flashing.
Skylights: A tight sealing is required around the skylights. A persistent metal sheet is installed on each side of the skylight to cover the area adequately.
Chimneys: Chimney requires special flashing as it has three different types of flashing around it. Small pieces of metal sheet flashing are used to cover the intersections around the chimney and the roof. In addition, there is a large area under the chimney, which is sealed with a straight metal sheet.
Dormers: Dormers are often constructed to add more space to the house. It helps light to let in and provides ventilation for the upper areas of the home. Multiple square pieces are required to install flashing between every row of the shingles.
Valleys: When the two slopes of the roof meet at a certain point, that area is known as a valley. Flashing is essential in that area of the roof. The water falls from both the slopes to the valley. The valley area already has an intersection that carries the water to the roof and causes leakage problems.If the flashing is not done correctly, there is a high risk of water leakage. A long piece of metal sheet is required to place flashing on the valleys of the roof.
Roof flashing is integral to your roofing system as it shields the home from moisture damage. Flashing secures the different parts of the roofs that intersect at a specific area of your roof. The water can quickly come to your homes through those intersections during rains. Thus, it is necessary to seal those areas with good roof flashing to avoid water leakage and moisture issues.
