Best Quality Roof Flashings & Sealants – Waterproof Your Roof with Confidence

Roof flashings are key to ensuring your roof is protected from wet weather. Flashings are custom-designed for the parts of a roof that form natural points of ingress for moisture and other contaminants. MRF Roofing is Sydney’s trusted go-to for a full range of flashings and sealants designed to keep the water out and ensure you get the most out of your investment in your roof. Whether you’re working on a new installation or replacing old materials, our Colorbond roofing & flashing range is built for long-term performance and a seamless finish.

Designed for both residential and industrial applications, our flashings are custom-designed to integrate with modern roofing systems, including roof flashing Colorbond options in all the classic colours.

Full Range of Roof Flashings Available

At MRF Roofing, we understand that every roof is unique. Our experienced team are ready to help you find the right flashing for the job. Whether you’re taking on a big commercial fitout or a simple garden shed, we’ll help make sure the roof is secure with no leaks through our range of flashings.

Colorbond® Roof Flashings

We supply pre-made and custom-folded Colorbond® roof flashings in every standard profile and colour. These flashings are ideal for critical areas such as:

• Wall junctions
• Valleys
• Ridges
• Roof edges

Built from robust Colorbond steel, they provide a sleek finish while delivering industry-leading corrosion resistance and weather protection. Regardless of the style, if it’s apron, ridge or flat, our roof flashing Colorbond range is the perfect match for Australian conditions.

Curve Cappings and Flashings

Need flashings for a curved or heritage-style roof? Our curve cappings and flashings are specially made to cater to roofs that naturally curve. These are common in older style and heritage buildings, but can also crop up as flair in modern designs. Whatever the particular quirk of the architecture, MRF Roofing has you covered.

These custom solutions are perfect for homeowners, builders, and architects who want both function and aesthetic form. Each piece is manufactured to your specifications, ensuring both a smooth fit and a watertight seal, even on the most complex designs.

Dektite Roof Flashing

Dektite roof flashing is the go-to solution for sealing around protrusions such as:

• Pipes
• Vents
• Chimney flues

Made from UV-stable silicone and rubber materials, Dektite flashings are flexible and heat resistant, making them ideal for Australian rooftops. With self-sealing guaranteeing a waterproof finish every time, Dektite flashings are an inspired choice. You can also eliminate the corrosion factor by choosing them. MRF Roofing offers Dektite roof flashing compatible with both Colorbond® and tiled roofing systems.

Velux Skylights and Flashings

Installing skylights? Ensure they’re properly sealed with our complete range of Velux skylights and flashings. Designed specifically for Velux installations, these flashings guarantee leak-proof performance on:

• Metal roofs

• Low-pitch or steep-slope applications

Whether you’re integrating skylights into a new build or upgrading an existing space, our Velux skylights and flashings ensure flawless integration with Colorbond® systems. Protect your investment with flashings that perform and last.
