Roof ventilators are key factors for a healthy and comfortable home. If you need to replace your ventilation system and are unsure where to start, we’ve got you covered. Shopping around for new roof ventilators can be overwhelming, especially due to the information you need to consider.
We’ll examine why roof ventilators are essential and the top eight questions to ask when deciding which one is right for you.
What are roof ventilators for?
Roof ventilation systems are in place to help air circulate through an attic or roof space. Roof ventilators allow hot air to flow out of the vents, which is beneficial to your home and your comfort, as it stops your attic from overheating. Ventilation systems also help prevent the build-up of mould and condensation, helping you avoid the health risks that can follow.
Let’s take a closer look at why roof ventilators are so important.
Why is roof ventilation important?
Roof ventilators play a significant role in your home and work to keep your home as comfortable and safe as possible. Roof vents benefit your home’s interior, keeping your roof cavity and attic space in good condition.
Here are some reasons why roof ventilation is essential:
Temperature regulation
Roof ventilation systems regulate the temperature in a home, which is beneficial in places like Australia that experience a range of weather and temperatures, such as extreme heat. As hot air rises, roof vents allow it to escape as cooler air circulates, maintaining a comfortable temperature.
This helps with energy costs as there’s less reliance on heating and cooling systems, and keeps you feeling content in your home.
Moisture and mould prevention and control
Roof vents reduce the build-up of moisture in a roof, which can lead to the growth of mould, wood rot and damage to internal structures. Roof ventilation helps reduce humidity in a roof through air circulation.
Improved indoor air quality
By allowing damp, humid or hot air to escape and promoting the flow of cooler fresh air, roof vents help to improve indoor air quality. A roof vent acts as an air conditioner, helping with odours, pollutants and allergens and creating a healthier living space for you and your family.
Prolonging the lifespan of roofing materials
Effective roof ventilation can help prolong your roof’s lifespan by preventing excessive moisture and heat from building up. Roofing materials that are exposed to high temperatures and trapped moisture are more likely to decay quicker, leading to costly repairs or replacements.
The top 8 questions to ask when buying roof ventilators
Overall, roof ventilation is vital for an energy-efficient, safe and comfortable home. Let’s look at the top eight questions to ask when finding the right one for your home.
1. What type of roof ventilator best suits my home’s design and climate?
The different styles of roofs and the climate you live in can affect the type of roof ventilator that’s best for you. Some roof ventilators work best on flat roofs, while others work better on pitched roofs. Additionally, different climates can affect the roof ventilation you may need.
For example, wind-driven ventilators work better in windy climates, and the amount of sunlighy you get affects solar-powered vents, which is worth considering.
2. How many roof ventilators do I need?
When considering the number of roof ventilators you need, consider the climate, the size of your home and the design of the roof. A roofing professional can advise you on the number of ventilators to install due to your home’s specific requirements.
3. What materials are roof ventilators made from?
Metal, plastic or composite materials are the materials used for roof vents. The different materials can have an impact on the maintenance needs of the vent, its durability and its lifespan. For example, a metal vent will have a longer lifespan and is made with recyclable materials, unlike a plastic vent.
4. How easy is the installation process, and can I do it myself?
There are some vents that you can install yourself, but others may require the skills of a professional. For example, a static vent, like a wind turbine, is the easiest to install due to its small size, which makes it easier to handle. Other vents, such as ridge vents, are larger and potentially more difficult to install yourself.
Consider your skills, experience and the required tools to install it yourself. It may be a better option to hire a roofing contractor.
5. What’s the warranty period for roof ventilators, and what does it cover?
Consider the warranty period, coverage, and exclusions when purchasing a roof vent. A warranty will give you peace of mind and protection against manufacturing defects and any other issues that may arise.
6. Are roof vents energy-efficient?
Energy-efficient roof vents can help to reduce your energy consumption and lower energy bills in your home. In general, adequate roof ventilation helps maintain the temperature, leading to less need for air conditioning and heating systems.
7. How much do roof ventilation systems cost?
The cost of a roof vent can depend on the type of vent, the material used, and the installation requirements. By looking around at the different options, you can make an informed decision based on long-term maintenance costs or any additional costs.
For example, a solar roof ventilation system may be expensive to install but may be cost-effective as it will positively impact your electricity bills and energy costs in the long run.
8. How do I know what the best type of vent is for me?
Taking into account the size of your roof, the climate you live in, and your budget can help you decide which vent is the best option for your home. A professional roof contractor can offer advice and their opinion, and by comparing quotes, you can make a well-informed decision that suits your circumstances.
Once you’ve asked the key questions to help you decide, it may be time to find a professional to install your roof vents.
Choosing the right ventilator supplier
Choosing the right supplier is vital in order for the most effective and efficient roof vents. The supplier needs to be reliable and reputable, so consider these factors when choosing the one for you:
- Do your research and gather recommendations
- Check for the supplier’s licence and certifications
- Compare the quotes to find the best option that’s most suited to you
Once you’ve considered all your options, you’ll be able to make an informed decision about the supplier and the roof ventilation system required for your home.
