Flashing Assistance from our Top-Notch Roofers
Upon first glance, it might look like your roof only consists of shingles and panels. In case you are unfamiliar, roof flashing is a material that provides protection for multiple parts of your roof. There are many different types of flashing. They are often fabricated from multiple kinds of materials, from plastic, to roofing felt, to rubber, and are built from a rust-resistant metal.
What Does Flashing Do?
Thanks to its durability, flashing is used to prevent water from passing through the various structures of a roof. Additionally, it is referred to as a weather-resistant barrier. It is strategically placed over wall construction and roof joints, as well as valleys, skylights, chimneys, and pipes. The placement of roof flashing prevents water from penetrating and damaging your roof.
For example, flashing might direct water from the two slopes of a roof valley down into your gutters. It can also be used to direct water away from your chimney, the edges of your roof, and important parts of your home like pipes and flues.
Types of Flashing
There are many types of roof flashing with different shapes that are placed on different spaces on your roof.
Valley flashing is placed on a roof valley and moves water from two slopes, in a valley-shape, into your gutter.
Step flashing is built entirely of metal sheets cut into right-angles. Each right-angled section is overlaid and is caulked underneath things like skylights or siding. Additionally, it is used to protect dormers, a roofed structure on many architectural styles, as well as chimneys.
Chimney flashing is used to direct water away from your chimney. With base flashing as a foundation, saddle flashing on top, and step flashing on the sides, it prevents water from penetrating and damaging your chimney, which can be extremely costly to fix. Cap flashing is also caulked into the chimney for extra protection.
Continuous flashing is a type of flashing that is placed between a sloped roof and a vertical wall to protect a roof joint, creating a “continuous” flow that protects your roof from water damage.
Vent Pipe Flashing
Vent pipe flashing is placed into your shingles after it is applied. It consists of a cone flange and a foundational flange and is used to protect pipes and flues on your home.
Drip edges are a type of flashing that protect the edges of your roof. Once installed, they protect your roof by preventing water from reaching under its rakes and eaves.
Roof flashing is one of the many materials used in roof building to protect your home and improve the longevity of your roof. Understanding how flashing works can assist you in identifying problems involving water leakage and damage in your roof. This allows you to effectively communicate with your roofing contractor and fix your problem in a quick, stress-free manner.
