A roofing system has many different parts that work together to ensure that your home is protected from the elements. Shingles, sheathing, fascias, soffits, and a gutter system are just a few of the many parts. A main piece of your roof system that helps protect your home is flashing. Flashing is an important reason on why roofs will last for so long.
What is Flashing?
Flashing is a thin sheet of material that is placed over the gaps, cracks, and crevices of a roof. When different areas of the roof meet, flashing is installed to cover the connecting areas that are exposed. The flashing is placed on top of the sheathing before any of the tiles or shingles are hammered into place.
What Does It Do?
When different parts of the roof meet each other, like near the chimney, there will be slits that are exposed and vulnerable. If these areas are not protected, water and moisture can seep into the crevices and start rotting the wood from underneath. This will also allow water damage and the growth of mold to begin. By placing flashing over these meeting points, your roof can stay protected, which will lengthen its lifespan.
What Materials to Choose From?
When flashing is installed on your roof, you have a few materials to choose from. One of the most popular options is aluminum. Of all materials this is the easiest one to bend and form to the areas it will be applied to. It is an inexpensive and durable option to choose for your roof. If you are looking for the most durable option, then consider going for copper flashing. This material is one of the most durable, but it’s rather difficult to fit to the selected area. Lead is another material that can be used, but it’s mainly used for the flashing around chimneys.
Flashing is a part of your roof that you normally wouldn’t notice, but is one of the most important pieces. While it is durable, it does not last as long as other roofing materials, like shingles. Sometimes flashing will need to be replaced throughout the life of your roof. To have your flashing inspected, replaced, or both, give Preferred Exterior a ring.
