All About Roof Flashing, the Ultimate Water Protection

Your roof is your home's first line of defence against the elements. But what protects the roof itself? That's where roof flashing comes in. In this blog post, brought to you by Buda, your supplier for your building and hardware needs, we'll discuss the ins and outs of roof flashing, exploring the different types of flashing available and what lead flashing is used for.

Why is Roof Flashing Important?

Roof flashing might seem minor, but it plays a vital role in safeguarding homes. It's a thin sheet of material installed at critical points like roof intersections, edges, chimneys, skylights, and anywhere tiles meet on your roof.

Think of flashing as a series of seals that direct water away from vulnerable areas and prevent leaks that can cause extensive damage to the roof structure and the interior of your home.

What is Lead Flashing Used For?

Lead flashing is a time-tested and highly effective material used in roofing and construction. Its unique properties make it an ideal choice for various applications, including:

• Chimney Flashing: Lead's malleability allows it to conform perfectly to the irregular shapes around chimneys, creating a watertight seal.

• Valley Flashing: Lead flashing is excellent for sealing the valleys where two roof slopes meet, effectively preventing water from seeping into the vulnerable joints.

• Skylight Flashing: It provides a durable and weather-resistant seal around skylights, protecting the surrounding area from water damage.

• Wall Flashing: Lead flashing creates a secure barrier between the roof and walls, preventing water from penetrating the building envelope.

Lead flashing's durability and resistance to corrosion make it a long-lasting and reliable solution for various roofing applications.

Types of Roof Flashing in Australia

Australian homes come in all shapes and sizes, and so do their roofs. Here's a look at the most common types of roof flashing used in Australia, along with their advantages and considerations:

Continuous Flashing (Apron Flashing)

This popular choice is a single sheet of metal, typically copper, aluminium, or steel, installed over the joint between your roof tiles and the wall. It offers a clean finish and exceptional protection against water intrusion. Copper flashing is highly durable but comes at a premium price. Aluminium is a cost-effective option and easy to install, while stainless steel provides excellent strength but can be trickier to work with.

Ideal for: Metal roofs due to their smooth surface. May not be suitable for tiled roofs because of their uneven profile.

Step Flashing

This flashing type is specifically designed for tiled roofs. Installed in a series of overlapping steps, each piece covers the one below, starting from the roof edge and working its way up to meet the wall or chimney. This step-like design allows water to flow down the roof and away from potential leak points.

Ideal for: Tiled roofs due to their uneven surface, tiled roofs are ideal. They are also well-suited for steeper roof profiles, like gable roofs, where gravity aids water flow.

Drip Edge Flashing

As the name suggests, drip edge flashing is installed at the roof's edges to prevent water from seeping into the eaves and causing damage. It's inexpensive, easy to install, and works well with most roof profiles. While highly functional, it might not be the most aesthetically pleasing option.

Valley Flashing

For roofs with valleys where two slopes meet, valley flashing is a must. These valleys are natural water collection points, and special flashing is needed to prevent water from accumulating and causing leaks.

Metal Flashing for Flat Roofs

Flat roofs require a unique solution – TPO-coated metal flashing. This special type of flashing features a thermoplastic coat that can be welded to the roof membrane, creating a watertight seal.
