The Importance of Roof Flashing

Roof flashing plays a critical role in the integrity of your roof. It secures joints in your roof and places that tend to receive a lot of water. Roof flashing redirects water from vulnerable areas of the roof and into gutters. Flashing plays an important role in preventing leaks. First Out Roofing will help you ensure that the roof flashing is installed properly and is kept in good condition. We can also assist you with any other roofing problems. Our team has more than 25 years of experience and we always provide a solution.

Why Is Roof Flashing So Crucial

Roofs are meant to keep elements out of your home or business. They offer protection for your family or employees. Modern roofs are built to last anywhere from 15 years to a lifetime. However, every roof can be subject to weak points, such as leaking. This is where roof flashing comes to play. 

The most vulnerable parts of a roof are joints and penetration. What is a joint? It is the part where two slopes meet. Most homes and businesses have joints and valleys on their roof unless your roof is a complete rectangle. A penetration is anything that requires holes in your roof. Some common examples include vents, skylights, and chimneys. Anywhere that there are joints and penetrations in your roof, there is an opportunity for water to seep into your home or business. Flashing is installed in these areas to prevent the water from getting in. Roof flashing is made up of materials that are not easily penetrated by water.

A Deeper Look Into Areas That Need Flashing

First Out Roofing is here to help explain where roof flashing is necessary.


A valley is another name for a joint. It is the area where two slopes meet. Both slopes direct water into the valley and the valley directs the water down that section of the roof. This can create a leakage problem during a storm. A gushing stream of water can gather in the valley and create a risk of leakage.

The roof flashing is usually made of long pieces of sheet metal that fit the shape of the valley. The flashing is then tightly sealed between shingles on both slopes.


Skylights provide a way for sunlight to enter your home or business, but you don’t want them to provide a way for water to get in too. To ensure that the skylights have a tight seal, a continuous sheet of flashing is installed on each side of the skylight.


If there is one area that needs flashing the most, it is the chimney. It requires special flashing and is usually made up of three parts: step, apron, and cricket. Step flashing directs water away from the chimney and onto the roof. The apron is installed below the chimney and the cricket is installed above it.
