Walkertown Roofing: Article About Types Of Flashing
The flashing on your roof is one of the single most important factors to consider. It protects the seams on your roof from leaks. Without proper flashing, even the most expensive roof covering is vulnerable to leaks, and there are certain areas of your home that need flashing more than others. Here are some key types of flashing that Walkertown roofing companies can install on your behalf.
One important type of flashing is continuous flashing, which is meant to protect the space between a vertical wall and a sloped roof. This flashing is important because water runs down the slope and continuously hits the vertical wall. A piece of flashing here prevents the roof from leaking. It's important to have this piece of flashing checked twice a year.
Another type of flashing is step flashing, which is used to protect dormer side walls, chimneys and skylights. This type of flashing is shaped into right angles to fit securely against the roof covering and the material that sticks out of the roof, such as a chimney. Each piece of step flashing overlaps the other. The vertical edge is either tucked underneath the siding or covered with a secondary piece of flashing known as counter flashing.

While step flashing is sometimes used around chimneys, there is also a type of flashing known as chimney flashing that could be used. However, chimney flashing is actually a series of different types of flashing that come together to protect the area around the chimney. These include continuous flashing used around the base, step flashing used along the side, and cap flashing. This top layer is typically caulked or mortared into the chimney.
Certain roofs also need valley flashing. This type of flashing is used to cover the seam that is formed when two different roof planes come together to form a valley. Since water is drawn to these valleys and runs down them continuously during a rainstorm, the seam in this area is prone to leaks. Valley flashing is typically "W" shaped to funnel water down the roof while avoiding leaks.
Another very important piece of flashing is drip edge flashing. As the name suggests, it's specifically designed to prevent the flow of water underneath the edge of the roof. This type of flashing can typically be seen around the eaves and rakes of the roof. If homes are missing any type of flashing, it's often the drip edge flashing. Contact a local roofer to inspect your home if you're unsure if you have this type of flashing. If you're missing it, you can have the roofer install it for a fairly reasonable price.
