Whenever we talk about roofing components then flashing comes as the last part out of a list of important stuff. Most of the homeowners don’t even know that it plays a vital role in protecting the roof health as well as house health. If you want to know about the flashing of a roof from basic to its importance, then read it till the end.
An Introduction to Roof Flashing
You can easily find a thin galvanized sheet at critical areas of the roof where the horizontal plane meets a vertical surface like a wall or a dormer. This is roof flashing and its main purpose is to water away from the roof surface. Flashing is crafted to surround roof features, such as vents, chimneys, and skylights. The professional roofers install flashing in a way that water runs down the side of the flashing and directs to the shingles instead of flowing into the roof deck.
Why it’s Important to Install Roof Flashing
After a brief introduction of flashing on the roof, it is easy to understand its main purpose. That is to complete a roofing system’s waterproofing surface. Without the flashing, it is hard to protect the vulnerable components like the deck and trusses from getting damaged from rainwater. That’s why residential roofing experts begin their inspection from flashing when the roof has a complaint of leakage.
Materials Used for Flashing
A few years back, roofing experts used to use materials such as lead or lead-coating as flashing. With the passage of time, the following materials have been added to this list.
Aluminum – Aluminium is light in weight and easier to install. Plain aluminum reacts and degrades when in contact with the alkaline surface. Thus, the roofing experts suggest aluminum be coated with concrete or masonry. Most of the homeowners prefer to have a coating of their flashings so as to prevent it from corrosion.
Copper – Copper roofing is highly durable and attains longevity. Along with this, it is malleable and takes soldering well. Conversely, some homeowners dislike this material as it does discolor into a plating. But others like this and you will still find copper flashing around chimneys.
Steel – Steel is most homeowner’s choice for flashing. It is corrosion free when galvanized, malleable, and has aesthetically value.
Roof Flashing Maintenance
Regular inspection of the roof and flashing helps homeowners to know the condition. Check out if there is any crack, broken edge from the exterior of the roof. Also, don’t forget to have a look at the attic walls and ceiling. If there are signs of leakage or any yellowish spots, then it’s the right time to repair it.
