What Is Gutter Flashing?
Gutter flashing is a versatile waterproofing tool that can be used to keep water away from one area and divert it to another. Flashing can be bought by the foot and is recommended as a way to increase the efficiency of your gutters.
Gutter flashings can be installed just beneath the roof line and inside the gutter. They work by stopping water from running behind a gutter and seeping into building materials and the infrastructure of a house. Flashings are bent at a 35-degree angle, which is statistically the best for diverting water.
Gutter flashings come in a standard size of 2x3 inches, 10 feet long. However, depending on the material required, you can have gutter flashings made to fit if water leakage around your roof is a big problem. Standard pieces will be cut to this size, but you can order large lengths of flashing that you can cut to size yourself.
Gutter flashings come in 2 different materials: aluminum and plastic. Plastic is used for its ability to adapt to complex gutter systems, while aluminum is used for its durability and the fact that it will last a lot longer despite being more expensive.
