Roof Ventilation & Whirlybirds in Wollongong
Professionally Installed Smart roof ventilation systems that reduce heat, moisture, and long-term roof damage.
Your local Wollongong Roof Ventilation Installation Service
At Profilio Metal Roofing (PMR), we specialise in roof ventilation systems designed to reduce heat, control moisture, and improve the performance of metal roofs across Wollongong and the wider Illawarra area.
Whether you’re dealing with extreme heat in summer, condensation issues, or poor airflow in your roof cavity, professional roof ventilation can make a significant difference to comfort, energy efficiency, and the lifespan of your roof.
Professional Roof Ventilation Systems for Metal Roofs
Roof ventilation works by allowing hot, trapped air to escape from your roof space, while drawing in cooler outside air. This continuous airflow helps regulate internal temperatures and prevents moisture buildup that can lead to rust, mould, and structural damage.
PMR installs a range of roof ventilation systems suited specifically to metal roofing, including passive and powered solutions depending on your roof type, pitch, and location.
What Is Roof Ventilation?
Roof ventilation refers to the controlled movement of air through your roof cavity using purpose-built roof vents and ventilators.
For homes and buildings in Wollongong’s coastal climate, roof ventilation is especially important for managing heat and humidity.
A properly designed roof ventilation system can:
reduce cavity Temperatures
lower cooling costs for Your Family Home
Improve indoor comfort
Extend life on metal roofing materials
Roof Whirlybirds (Turbine Roof Ventilation)
A roof whirlybird—also known as a turbine vent—is one of the most common and cost-effective forms of roof ventilation.
Benefits of roof whirlybirds:
Wind-driven (no power required)
Helps extract hot air from roof cavities
Reduces heat buildup under metal roofs
Low maintenance and long-lasting
Whirlybirds spin as wind passes over them, creating suction that pulls hot air out of the roof space. PMR installs roof whirlybirds that are suitable for metal roofing profiles and sealed correctly to prevent leaks.
Types of Roof Ventilation Systems We Install
Passive Roof Ventilation (Whirlybirds & Roof Vents)
Passive systems rely on wind and natural airflow to extract heat.
Includes:
Roof whirlybirds
Static roof vents
Box vents
These are ideal for many residential metal roofs and are a popular choice due to their simplicity and reliability.
Powered & Solar Roof Ventilation Systems
For low-wind areas or roofs with significant heat buildup, powered options may be recommended. These systems:
Actively extract hot air.
.
Maintain airflow even on still days
Can be solar-powered for energy efficiency.
PMR can assess whether a powered roof ventilation system is suitable for your property.
Roof Vents for Metal Roofing
Not all roof vents are suitable for metal roofs. Poor installation or incorrect vent selection can lead to leaks and premature roof damage.
At PMR, we:
Match roof vents to your metal roofing profile.
Use correct flashings and seals and
install vents without compromising roof integrity.

Frequently asked Questions About Roof Vent Installation
Do I need roof ventilation on a metal roof?
Yes. Metal roofs can trap heat and condensation without proper roof ventilation, especially in warmer or coastal areas.
How many roof whirlybirds do I need?
The number depends on roof size, pitch, and airflow requirements. PMR will calculate the correct setup during inspection.
Are roof vents and whirlybirds the same?
A roof whirlybird is a type of roof vent. “Roof vents” is a broader term that includes whirlybirds, static vents, and powered systems.
