ROOFING

Roof Ventilation in Melbourne & Geelong

A roof cavity that can't shed heat and moisture properly makes the rooms underneath harder to cool and can lead to condensation problems over time. We install whirlybirds and other ventilation systems across Melbourne and Geelong to keep air moving through the roof space.

MORE DETAIL

Signs of Poor Roof Ventilation

A hot upper floor, with rooms under the roof that stay noticeably hotter than the rest of the house, is a common sign. Condensation in the roof cavity is moisture buildup that can lead to timber and insulation problems, and a musty smell is often a sign of trapped moisture in the roof space.

FAQS

Frequently Asked Questions

Do whirlybirds actually reduce heat?

They help move hot air out of the roof cavity, which can reduce heat transfer into the rooms below, particularly in summer.

How many ventilation units does my roof need?

This depends on roof size and design. We'll assess and recommend a number as part of the quote.

Do roof ventilation units need power?

Whirlybirds are passive and donâ€™t need power. Powered ventilation options are available where more airflow is needed.

What's the difference between passive and powered ventilation?

Passive units, like whirlybirds, rely on wind and rising heat. Powered units use a fan for consistent airflow regardless of wind.

Do ventilation units cause roof leaks?

Properly installed and flashed, they shouldn't. This is a key part of a correct installation.

How long do roof ventilation units last?

Most units are built to last many years with minimal maintenance. [Confirm specific figure for publish.]

What does roof ventilation installation cost?

This depends on the type and number of units required for your roof.

Does ventilation help with condensation problems?

Yes, improving airflow is one of the main ways to reduce condensation buildup in a roof cavity.
