Common Types of Roof Flashing

roof flashing-roof health

Water leakage is one of the most common problems that occur with both residential and commercial roofs. Water is typically able to enter a roof structure following a rain. If it continues to seep over a long period, it can gradually damage and weaken the roof. Over time, this can lead to expensive repairs and even a more costly full roof replacement which averages at around $8,074.

The good news is that roof flashing is an easy and convenient way of minimizing this risk. Flashing is a way of sealing off the seams and joints along a roof, especially at the most susceptible spots. These include chimneys, roof vents, skylights, valleys as well as any edges and ridges along the roof. Once these susceptible areas are properly sealed with flashing, your roof is very well protected against water damage.

Here is a look at other benefits of roof flashing as well as common types of flashing used in residential and commercial roofing.

Benefits of Roofing Flashing

In addition to keeping your roofing safe from water damage, roof flashing also offers a wide range of other benefits. These include:

Weather Proofing

When installed by a qualified professional, roofing flashing is effective enough to weather-proof your roof against most, if not all, outdoor elements. This includes protection against wind-related damage as well. By properly sealing the roof, flashing prevents insects, rodents, and birds from accessing vulnerable spots like the vents and chimneys.

Aesthetics

You have virtually endless options to choose from when it comes to the look and feel of a roof  flashing. This allows you to add flashing as a very customized and tailored aesthetic feature on your roof.

Improved Property Value

Potential buyers tend to have the roofing of a building carefully examined before closing the deal. If you add flashing to your roof, it also adds to the overall value of the property.

Types of Roof Flashing

Different types of flashing are used at different sections of a roof. Here is a look at some of the most common types:

Drip Edge Flashing

A drip edge flashing, as the name suggests, is typically installed along the eaves or edges of your roof. This type of flashing protects the roof in case the roof gutters overflow or if it rains at a sideways angle. The water can drip along the last shingle and directly seep into the roof, causing significant damage. A drip edge flashing effectively prevents this.

Vent Pipe Flashing

If you have vent pipes or any other pipes passing along the rooftop, you will need vent pipe flashing. This type of flashing comprises of a cylindrical structure ending in a flat bottom. With this shape, vent pipe flashing is able to cover pipes very effectively so that there are no sealed joints or seams around them.

Valley Flashing

A valley refers to that area of your roof where two sloped sections meet, often making a V or a dip at an angle. Valleys are highly vulnerable to water leaks, which is why it is very important to seal them. A valley flashing is installed at the very spot where the two sections meet. It runs along the full length of the valley all the way to the drip edge. When installed right, the valley flashing should overlap the drip edge flashing.

Step Flashing

If you have roof features like a chimney, vent, or skylight, you will require step flashing. This type of flashing comprises of tightly overlapping steps which slip under steps of shingles. One side of step flashing is laid flush to the side of the roof feature while it is secured to the roof bricks or stones with cement.
