We all know that roof vents are an important aspect of our homes, but most people don’t necessarily know how roof vents work. It goes without saying that roof vents stimulate the airflow in a loft or attic, but that is the extent of most people’s knowledge.
Here at ERoofing, we want to be transparent with our products so that our customers know exactly what they are buying and why. With this in mind, we have put together this breakdown of how roof vents work and why they are important.
Why is Roof Ventilation Important?
Roof ventilation is essential in preventing condensation, mould, and rot. Our living habits produce a lot of moisture and, if this moisture is not cleared and is allowed to settle, it results in condensation. Condensation then leads to bigger issues such as mould and rot which can threaten the structural integrity of your home, as well as your health. Therefore, it is important to ventilate your loft as this warm condensation will rise and make the space a hotbed for mould.
Additionally, ample ventilation can drastically improve your roof’s lifespan as it prevents the build-up of heat that damages underlayment, rafters, framing, and more. The vents allow this detrimental hot air to escape, extending your roof’s lifetime. Similarly, roof ventilation assists the regulation of temperature within your home which could significantly reduce your energy bill.
What is the Concept of Roof Ventilation?
Quite simply, roof vents supply a constant airflow through your loft space which removes hot air and moisture from the space. A roof ventilation system is compiled of intake vents and exhaust vents that are fitted strategically in the roof. These different types of vents allow the air to circulate in the right amounts and directions. It is imperative to correctly balance the intake and exhaust ventilation in order to prevent conditioned air from being removed too swiftly.
How Can You Tell if the Ventilation is Working?
It is more the case that you will be able to tell when your roof ventilation is not working. If your roof vents are not functioning properly, you might notice frost and ridges of ice in your loft during winter, hot ceilings underneath your loft, rising energy bills, temperatures in the attic that do not coincide with the temperatures outside your home, and moisture, mildew, and mould in your loft.

What Causes Condensation and Damp in the Loft?
Moisture is produced when we shower, bathe, cook, and hang wet clothes to dry, and this hot air can become trapped in your loft. If the loft space is unventilated or is not being ventilated at a quick enough rate, the hot air will condensate on the cold spots of your loft. When this happens, the air returns to its liquid state and forms drops of water on the cold surfaces of your loft.
What Causes Strange Smells in the Loft?
During the summer months, many people notice an unusual smell in their loft; this is the smell of anti-corrosive products that have gotten hot and consequently given off a smell. With ample loft ventilation, the space will not get as hot and the smell will not be as prominent.
How Many Roof Vents Do You Need?
There is no simple answer to how many roof vents are needed for homes as each property is unique. Typically, two vents front and back is a good starting point, but if you find that you are still struggling with condensation, you can purchase and install more.
How Do You Maintain Your Roof Ventilation System?
Both your roof and its ventilation should be inspected at least twice a year. It will need to be inspected for weather damage like missing or broken roof tiles, loose vents, or cracks. Similarly, your vents will need to be cleared of any debris such as leaves to ensure that they are able to properly function. As well as this, you should inspect your loft for moisture damage and ensure that your insulation is in good condition.
