FAQs
What are soffit vents?
Soffit vents are installed under the eaves of your roof, allowing fresh air to enter your attic. They're great for boosting airflow and help with insulation by keeping your attic at an even temperature.
Also known as eave vents, they help to keep your attic cooler in summer and reduce the buildup of moisture and heat in the winter.
How long does it take to install soffit vents?
It depends on your property, but it can take anywhere from three/four hours up to one day to install about 20 eaves vents.
Can I install soffit vents myself?
It’s always recommended that an experienced installer be hired for this kind of job.
Not only does it involve working at height, which can be dangerous, but you’ll need to get a professional fit to make sure your vents work efficiently.
