Adding extra protective layer

Roof sarking adds an extra protective layer beneath your tiles or metal roof.

Our sarking installation services in Sydney help block moisture, reduce heat transfer, and improve the overall performance of your roof and ceiling insulation. Properly installed sarking acts like a second skin for your home, helping keep it drier, more energy‑efficient, and better protected from wind‑driven rain and dust.

How we install roof sarking

We start with a detailed roof inspection to confirm your roof structure is suitable and to plan the best way to add or upgrade sarking.

Our team carefully lays and secures high‑grade sarking membranes under tiles or metal sheets, neatly sealing overlaps and penetrations to create a continuous moisture barrier. We pay special attention to ridges, valleys, and flashings so your new sarking performs as intended—helping protect insulation, rafters, and your ceiling cavity from damp and condensation.

Benefits of sarking

Sarking is particularly valuable in Sydney’s climate, where heat, storms, and humidity all put pressure on your roof.

It improves thermal performance by reflecting radiant heat, helps stabilise indoor temperatures, and can reduce energy use for heating and cooling. As a moisture and dust barrier, sarking also helps prevent mould, ceiling stains, drafts, and ember attack in bushfire‑prone areas, adding another level of protection to your home.

Sarking questions

What is roof sarking?

Sarking is a reflective, water-resistant membrane installed under roof tiles or sheeting. It acts as a second line of defence against wind-driven rain and dust, and reflects heat.

Do I need sarking?

Many older homes were built without it. Sarking can help reduce leaks in heavy wind-driven rain, keep the roof space cooler in summer and reduce dust.

Can sarking be added to an existing roof?

Yes. On a tiled roof, tiles are lifted, the sarking is installed over the battens, and the tiles are relaid.

Does sarking help with energy efficiency?

Reflective sarking reflects radiant heat, which can help keep the roof space and home cooler in summer.
