FREQUENTLY ASKED QUESTIONS
ROOF VENT FAQS
1. How much do roof vents cost in Cape Town?
Whirlybird and turbine roof vents from BUSSEY ROOF VENTS start at R950 installed. Final pricing depends on the number of vents, roof type and access. Call Dean on 076 373 3009 for a free quote.
2. What is the difference between a whirlybird and a turbine roof vent?
A whirlybird is powered by the wind, while a turbine vent uses the stack effect to draw hot air out continuously. Both are highly effective and we will recommend the best option for your roof.
3. How many roof vents does my house need?
As a guide, most homes need one vent for roughly every 30 to 50 m2 of roof space. We assess your roof and attic volume on site to recommend the correct number.
4. Will roof vents stop mould and damp?
Yes. By removing trapped heat and moisture, roof vents reduce condensation, damp and mould at the source and keep your roof space dry and healthy.
5. Do roof vents cause leaks?
No. When installed correctly with proper flashing and sealing, roof vents are completely leak-proof. Our installations are guaranteed.
6. How much does industrial roof ventilation cost?
Industrial and warehouse ventilation is quoted per project depending on size, number of vents and roof type. Contact Dean for a site assessment and free quote.
7. Can you install vents on IBR and corrugated roofs?
Yes. We supply and install roof vents on tiled, IBR, corrugated and metal sheet roofs, with the correct flashings for a perfect seal.
8. Do whirlybird vents work when there is no wind?
Yes. Even in low or no wind, the design of whirlybird and turbine vents still allows hot air to escape through natural convection.
9. Which areas do you serve?
We serve Cape Town and surrounding areas including Brackenfell, Durbanville, Bellville, Kraaifontein, the Northern Suburbs and the wider Western Cape.
