In our first roof ventilation BLOG we explained what a system is – roof ventilation systems revisited – a system – a regular interacting or independent group of items forming a unified whole.

When we look at a roof ventilation system we need to look at a balanced system, of two ventilators opposing each other of the same volume to equalize the airflow throughout the roof cavity. With a pair of ventilators for each zone of the roofspace. This is the ingredient for a roof ventilation system that will alleviate the condensation of winter and keep your home cooler in summer.

Anything less will be a waste of your hard earned dollars. Universal Tile Ventilators for concrete and terracotta roof tiles and the Smoothline System for corrugated colorbond are balanced systems of the same volume and will perform for you with great results for decades.
