If you are a builder or roofer, you are probably already dealing with the NCC condensation management updates. Victoria has already brought in the 2025 rules, and the rest of the country is following suit by mid-2027. We all know proper roof ventilation is about way more than just ticking a compliance box—it is about stopping trapped moisture from wrecking a building over time.

There are plenty of ways to vent a roof, but we see a lot of trades running into the same issue: what happens when the roof is already on and the building surveyor asks about ventilation?

Our Alpine low-profile roof vents are designed exactly for this. You can install them, along with our aluminium eave or fascia vents, after the roof sheets or tiles are already fitted. It saves a massive headache on site. They are BAL-40 compliant right out of the box, super subtle on the roofline, and usually cost under a grand for an average-sized house.

We put together a quick guide comparing the different ways to vent a roof cavity under the new rules. Give it a read at the link below and see what makes the most sense for your next build.

If you look at the new NCC 2025 updates for roof ventilation, your first thought is probably: "This looks a whole lot more complicated than 2022."

But once you strip back the extra diagrams and finer details, the actual core rules haven't shifted as much as it seems. The focus is still heavily on managing condensation, but the calculations have actually been streamlined quite a bit.

We broke down the main changes in our latest article—including the new pitch ranges, how skillion vs. non-skillion roofs are handled now, and a handy new exemption for smaller spaces under 10m².

If you’re a builder, contractor, or architect trying to map out your next project, it’s worth a quick read to save yourself some headache on the math. Check out the full breakdown at the link on the Alpine Ventilation website below!

Low-profile roof vents vs rotary vents (whirlybirds) — which one is actually better for your roof?

It's a question we get a lot, especially from builders working on new builds and renovations. The short answer: it depends on the job — but for most modern homes, low-profile vents are coming out on top.

Here's why:

🔹 Low-profile vents cover both ducted and non-ducted applications. Rotary vents are non-ducted only — so if you need to vent a bathroom fan or rangehood, whirlybirds aren't even an option.

🔹 Got solar panels? Low-profile vents sit flat enough to go underneath them. Rotary vents don't.

🔹 No moving parts means no spinning noise on windy nights and nothing to wear out over time.

🔹 Building in a bushfire zone? Low-profile vents can achieve BAL-40 compliance without needing extra ember mesh — saving time and cost.

🔹 On still, wet days, rotary vents rely on wind to keep water out. Low-profile vents don't have that problem, and typically come with a larger flashing area for better weather protection.

Rotary vents still have their place — particularly when you need a larger open vent area or more Colorbond colour options. But for most new builds today, the Alpine low-profile roof vent is the smarter choice.

🚨 New NCC 2022 ventilation rules are in effect — does your home or build comply?

The updated regulations under section 10.8.2 introduce stricter requirements for exhaust fans and range hoods as part of Australia's Condensation Management provisions. These changes are designed to protect homes from excess moisture, mould and structural damage.

Here's a quick breakdown of what's changed:

🔹 Minimum flow rates: 90 m³/hr for bathrooms, 144 m³/hr for kitchens and laundries
🔹 Fans in bathrooms without natural ventilation must be interlocked with the light switch and include a 10-minute run-on timer
🔹 All fans and range hoods must now duct directly to outside — venting into roof cavities is no longer allowed
🔹 Ducted roof, fascia or eave vents are required, and both semi-rigid and flexible foil ducting are compliant options

Our exhaust fans feature powerful Japanese bearing motors that deliver flow rates well above the NCC minimums — because real-world ducted performance is always lower than lab specs.
