What Is Roof Flashing?

Roof flashing is a thin metal material used to direct water away from certain vulnerable areas of the roof. These areas include places where the roof meets vertical surfaces like walls, chimneys, vents, skylights, and roof valleys

Types of Commercial Roof Flashing

There are several types of flashing used in commercial roofing, each serving a specific purpose:

Continuous Flashing/Apron Flashing:

This is a long, single piece of metal that directs water downward, away from the roof’s shingles. It helps to ensure that water doesn’t get trapped on the roof.

Step Flashing:

This type of flashing consists of a rectangular metal piece folded at a 90-degree angle. It is used where the roof meets a wall to guide water away from the wall, preventing it from seeping inside.

Base Flashing:

Often used on chimneys, base flashing is one of two pieces of flashing required to keep rainwater from entering the building.

Counter Flashing:

This flashing is installed above the base flashing, usually around chimneys, to direct water away.

Drip Edges:

These are thin pieces of metal installed along the edges of the roof.

Materials Used in Commercial Roof Flashing

Different materials can be used for roof flashing, each with its benefits:

Copper Roof Flashing:

Copper is a highly durable and flexible material often used around chimneys. Its malleability makes it easy to shape, and it has a long lifespan.

Aluminium Flashing:

Aluminium is lightweight and easy to form, making it a popular choice for roof flashing.

Steel Flashing:

Steel flashing is corrosion-resistant, especially when it is galvanized. It also adds aesthetic value to the roof while being strong and flexible enough to be shaped as needed.

Roof Flashing Techniques

Several techniques are used to install roof flashing effectively:

Plumbing Vent Boot Flashing:

This is a cylindrical flashing that fits around a plumbing vent pipe to ensure water flows around the vent and off the roof, preventing leaks.

Step Flashing:

Installed where the roof meets a wall, step flashing keeps water away from the wall and directs it safely down the roof.

Counter Flashing:

Used mainly around chimneys, this technique involves two pieces of flashing. The base flashing is installed first, around the chimney’s base.

The Purpose of Roof Flashing

The primary purpose of roof flashing is to protect your building from water damage. Flashing acts as a barrier, ensuring that water flows off the roof rather than penetrating it.

In conclusion, roof flashing is a crucial component of any roofing system. Proper installation and maintenance of flashing are essential to prevent leaks and protect your building from water damage. Whether you’re installing a new roof or repairing an existing one, make sure that your roof’s flashing is in good condition to keep your building safe and dry.
