Roof Upgrades

If you’re replacing or upgrading a metal roof, you’re in the perfect spot to massively boost your home’s comfort and efficiency — but only if you get the insulation right.

Most people focus on the roof sheets. Smart people think about what’s under them.

⚒️ New Roof, Same Old Heat Problem?

Metal roofing is durable and stylish — but on a 35°C summer day, it turns into a frying pan. Without insulation, all that heat radiates into your ceiling space and through into your home. Then in winter, it does the reverse: sucks out your warmth.

If you’re going to the trouble (and cost) of a new roof, upgrading the insulation layer at the same time is a no-brainer.

🧱 Insulation Options for Roof Retrofits

Here’s what works best under new metal roofing:

  • Roofing Blanket (e.g. Supa-Therm):
    Combines thermal insulation with a reflective foil layer. Perfect for radiant heat.

  • Foil-Faced Batts:
    Installed in the ceiling cavity; reduces heat transfer and boosts R‑value fast.

  • Double Layer Systems:
    Pair a roofing blanket with ceiling batts for max performance.

  • Vapour Barriers & Moisture Control Layers:
    Essential in coastal or humid climates to prevent condensation and mould buildup.

🎯 Why Now is the Best Time

Installing insulation after a roof upgrade means extra labour, limited access, and higher costs.

Doing it during the roof replacement means:

  • Open access = faster install

  • Better insulation coverage

  • No future disruption

  • One clean compliance check for BASIX/NCC/etc.

  • Lower power bills from day one

🏡 Real Example: Roof Upgrade Done Right

“We replaced our old tin roof with Colorbond, added a roofing blanket + R5.0 ceiling batts — and the temp inside dropped by 5 degrees instantly. Power bill’s down 30%. Worth every cent.”
