While we often think of roof maintenance as a way of ensuring it remains weatherproof and structurally sound, it’s important to think about the way your roofing functions in the home too. Many homeowners forget about their roof ventilation, but it’s actually a significant part of its overall maintenance requirements and how well you protect your property and roofing from damage. The purpose is to keep the roof area as dry as possible, helping air to circulate and controlling the temperature within the roof space.
Here’s everything you need to know about roof ventilation systems.
Effects of Poorly Ventilated Roofs
If a roof is poorly ventilated, it can cause several issues, including damp caused by condensation. This can occur if warm air from the rest of your home reaches the cold attic or loft space and forms moisture droplets, like you may see on your windows in the Autumn and Winter months.
Damp in your roof space is something you want to avoid as it could cause major issues, such as damage to joists, rotting woodwork, mould and a deterioration of your roof insulation. Unfortunately, with modern homes looking for ways to conserve energy and keep in warmth, condensation damage is a growing problem, so it’s vital you ensure your roof ventilation is effective. If not, it could be incredibly time-consuming, stressful and costly to fix further down the line, especially if damp and mould work their way into the rest of your home.
What Is Roof Ventilation?
To prevent the effects of condensation damage, adequate roof ventilation is required. This will help to balance the difference between internal and external temperatures, giving warm air a means to escape. One of the most popular types of roof ventilation systems is vents. These features give warm air a path to the outside while drawing in colder air, achieving enhanced circulation within the roof space.
Choosing the Right Air Vents for Your Roof
There are actually several different types of air vent for roofs, including those installed in the ridges at the top of your roofing where the two sides meet. Ventilation for the eaves could be provided through vents at the fascias and soffits. You can also buy box vents, which are fitted in several places to provide sufficient ventilation.
The type of vents chosen will depend on your property and roof shape, as well as your existing ventilation. Your roofer will be able to talk through the various solutions available, including the option of breathable membranes if you’re having a new roof laid.
