A roof is a critical aspect of any building. If the roof is not up to a certain standard, the whole building’s integrity can be compromised. To make sure this doesn’t happen, you need to ensure the roof is put together properly.
To do this, you need to know a little about how roofs are built. One of the most important parts of the roofing job is called flashing.
What is flashing on a roof? Read on for the answer, along with some additional information about keeping safe on the job and the best flashing for a new roof.
What Is Flashing on a Roof
Roof flashing is a material used to prevent water infiltration at joints in a roofing system. Flashing on a roof is typically made of metals, such as aluminum or galvanized steel, although rubber, plastic, and composites are also used.
The most common application of roof flashing is at roof valleys, hips, dormers, vents, skylights, and chimneys.
The Importance of Flashing
Most roofing materials are not waterproof and need some type of protection from the elements. That is where flashing comes in. Roof flashing is installed in areas where the roofing material is especially vulnerable to water damage.
Different Types of Flashing
Flashing can be made up of different materials, such as aluminum, copper, stainless, or galvanized steel. But they can also be categorized by how they are installed. Here are the different types of flashing for your roof.
1. Base Flashing
Base flashing is installed on the vertical-horizontal intersections on a roof where the roof meets a vertical wall juncture. It is installed over underlayment but under the shingles so that it cannot be seen from below.
2. Step Flashing
Step flashing consists of L-shaped pieces of metal that are installed in a stair-step pattern, hence the name. Like base flashing, the metal flashing covers the seams where the roofing meets the wall and helps direct the water away from the home. The difference between them is that step flashing is used for side walls.
3. Counter Flashing
Counter flashing is installed over the base flashing, for its main purpose is to protect the latter. It is commonly seen between the roof surface and a chimney.
When installing counter flashing, it is helpful to install it while the chimney is being built. But that doesn’t mean you can’t install counter flashing to already built structures.
4. Continuous Flashing
Continuous flashing is a type of flashing that consists of a sheet of material that is installed over an entire section of the roof. This flashing redirects water from the roof into the gutter.
5. Skylight Flashing
Before telling your contractor that you need to install skylight flashing, check it first. The majority of skylights come pre-installed with flashings.
6. Valley Flashing
As in its name, valley flashing is a type of flashing installed along the valleys of a roof. This channels water away from these vulnerable areas.
7. Drip Edges
The drip edge is the metal strip that runs along the lower edge of the roof. It is installed over the roofing paper or felt and under the first course of shingles. Drip edges allow the water to drip off the edge of the roof instead of running down under the shingles.
8. Kickout Flashing
Kickout flashing is installed at the point where the step flashing ends, and the gutter starts. This flashing redirects water from the wall and into the gutter.
How to Install Roof Flashing
When installing flashing yourself, first, you need to measure the area where the flashing will be placed and cut the material to size.
Next, remove any old caulking or sealant from the joint and roughen the surface to help the new flashing adhere. Then apply a generous bead of sealant to the joint and press the flashing into place.
Finally, use a caulking gun to apply a layer of sealant over the top of the flashing.
Troubleshooting Flashing Issues
Over time, flashing can become damaged or loose, leading to leaks. If you see water damage or leaks inside your home, it is important to inspect the roof and flashing to see if they are the source of the problem.
Damages on your flashing can be obvious, for you would see visual abnormalities such as corrosion or physical damages like dents or cracks.
You may be able to repair minor damage yourself, but more severe damage will require the assistance of a roofing professional.
How to Repair Roof Flashing
A few things can cause flashing on a roof to become damaged and need to be repaired. The most common cause is exposure to wind and rain.
Over time, the flashing can become worn down and start to leak. If left untreated, this can cause severe damage to your home.
To repair flashing, you will need to remove the old damaged flashing and replace it with a new one. You can purchase flashing at most hardware stores.
Be sure to measure the area before you purchase the new flashing so you get the correct size.
Roof Flashing Maintenance
Flashing is a necessary component of any roofing system, and without proper maintenance, flashing can fail.
That is why regular flashing maintenance is therefore essential in order to keep your roof in good condition. When inspecting your roof, look for any gaps, cracks, or holes in the flashing, and repair or replace as necessary.
