Roofs are made up of more than just shingles. One of the most essential parts of any roof is the roof flashing, but the same type of flashing can’t be used for every area or type of roof. Roof flashing acts as an added layer of protection over the most critical areas of the roof. The flashing ensures water is directed away from that area and onto the shingle to make its way down the gutter system and away from your home. Without roof flashing, that water would settle into your roof deck and lead to a long list of potential problems within the home. Take a look at some of the most common types of roof flashing and what specific purpose they serve!
The area where a vertical wall meets a slanted roof creates a weak spot that’s prone to water damage. Continuous flashing prevents that issue by using one long piece of flashing to completely cover the area and redirect water away from the joint.
Step flashing is a rectangular type of flashing. This flashing is bent at a 90-degree angle so it’s perfect to put over wall to roof joints. Unlike continuous flashing, the separate rectangles can potentially allow water to get through. To prevent this, you just need to layer the step flashing to offer seamless protection against water damage.
Drip Edge Flashing
Drip edge flashing is typically used along the eaves of the roof. Water drips in these areas and without a drip edge flashing, damage would occur. Flashing along the drip edge is installed under the roofing felt to provide the best level of protection.
Roof features that stick up above the rest of the roof, such as chimneys and vents, need a specific type of flashing called base flashing. Base flashing is a type of continuous flashing that’s used to direct water away from the chimney or other feature on the roof. Without this flashing it’s very easy for water to make it’s way between the raised roof feature and the shingles, causing water damage.
When two valleys of a roof connect, there’s a weak spot for water to get through. Valley flashing is specifically made for this area of the roof. Valley flashing features a W shape to provide the best protection across both valleys of the roof, as well as the spot where they connect.
