What is a Portico?

One of the most important components of any roof is the flashing, and in particular, the portico flashing. In this article, we will discuss the importance of portico flashing and how it helps to protect the homeowner's roof.

First, it's important to understand exactly what portico flashing is and where it is located on a roof. A portico is a covered area at the entrance of a building, typically supported by columns. The flashing on a portico is the thin sheet of metal or other material that is used to seal the joints between the portico and the roof. It is located at the base of the portico, where it meets the roof, and is typically hidden behind the fascia board.

The primary purpose of portico flashing is to prevent water from infiltrating the roof and causing damage. Water that seeps into the roof can cause rot and other types of damage, which can be costly to repair. Portico flashing helps to direct water away from the roof and down the sides of the building, where it can be safely drained away.

In addition to protecting the roof from water damage, portico flashing also helps to protect the integrity of the roof itself. When water infiltrates a roof, it can cause the roofing materials to become weak and brittle. This can lead to leaks and other types of damage that can compromise the structure of the roof. By directing water away from the roof and sealing the joints between the portico and the roof, portico flashing helps to prevent these types of problems from occurring.

Another important benefit of portico flashing is that it helps to protect the home's foundation. Water that seeps into the roof can eventually find its way down to the foundation, where it can cause serious damage. By directing water away from the roof and sealing the joints between the portico and the roof, portico flashing helps to prevent this type of damage from occurring.

In conclusion, portico flashing is an important component of any roof. It helps to protect the roof from water damage, maintain the integrity of the roof itself, and protect the home's foundation. Homeowners should make sure that their portico flashing is in good condition and replace it as needed to ensure that their roof is protected.
