Everything You Need To Know About Roof Ventilation

Roof ventilation involves enhancing the air circulation in the space between your roof and ceiling or your attic. This is slightly different from ordinary room ventilation.

Unlike your room, most roofs don’t have doors and windows that can be opened on a hot day. Unless your attic doubles up as living space, you may need to install special ventilation systems and vents for efficient circulation.

Why Do You Need Roof Ventilation?

Most people rarely check their roofs unless they suspect a problem. Yet, without good ventilation, you need to constantly inspect your roof. You need to check for mould, mildew, rot, moisture accumulation and many more challenges. The best roof ventilation systems require minimal human input and only need a few inspections per year.

In summer, the weather in Sydney can be extremely hot and humid. This is an ideal situation for the development of mould, mildew and rots in your attic frames. A good ventilation system prevents this by continuously letting warm moist air out and fresh cool air in.

The constant inflow of fresh air is vital when preventing the spread of diseases like flu, which is rampant in the winter. The list below highlights some of the specific advantages of roof ventilation.

Benefits of Roof Ventilation

1. Reduces Energy Bills

Roof ventilation systems can reduce your reliance on air conditioning. They allow the constant inflow of cool air even on the hottest days. This is essential in the summer when you need to cool your house down.

2. Enhances The Lifespan Of Your Roof

Poorly ventilated attics allow the accumulation of moisture in your roof. This moisture can find its way into the structural components of your roof. Long term accumulation of moisture can develop rot and compromise the integrity of the roof. Without good ventilation, you may need to replace or repair your entire roof.

3. Controls Pests and Pathogens

Sicknesses and ailments such as the flu spread faster in poorly ventilated environments. Good air circulation introduces fresh air and pushes out the contaminated one.

Also, most pests like to settle in warm, moist and dark rooms, especially in the winter. The ventilation system creates and sustains cool dry areas that discourage the nesting and multiplication of pests.

Types of Roof Ventilation

There are several different types of roof ventilation systems used in Australia today. Here are a couple of examples
