Jay Jay Building Supplies has been proudly providing building supplies in Penrith and across Western Sydney for over 40 years. It all began in Silverdale, where Robert Goldfinch started out supplying metal roofing directly from home with a simple goal. To offer builders quality products at better prices.

Since then, we’ve grown well beyond roofing. Now based in Penrith and operating across five factory units, we supply a wide range of building materials in Penrith and across Western Sydney including structural products, insulation, skylights, fasteners, and more. We focus on supporting tradies and builders with reliable supply and down-to-earth service.

While trade is at the heart of what we do, we’re also happy to assist the general public where possible. Whether you’re on the tools every day or taking on a weekend project, we’re here to help.

Why Choose Our Building Supplies in Penrith?

Still family owned and operated, we remain committed to the same values we started with: honest service, fair pricing, and a deep understanding of the building game.
