If your flat roof is not adequately ventilated then warm air can become trapped beneath the insulation layer of the roof and cause condensation to form.

What are Flat Roof Vents?

This can lead damp and mould to build up in your living areas, increasing the risk of harming your general health and respiratory system in particular. And it can cause structural damage to the flat roof itself, such as making the water proof membranes blister and tear, that will then need expensive replacement or repair. The solution is a flat roof vent.

Choosing your Flat Roof Vents

At Building Supplies Online we have an extensive range of flat roof vent and accessories from quality brands such as Ubbink, and Klober. Our range includes flat roof vent products and breather pipes, suitable for both cold and warm flat roofs. Many of our flat roof vent products, such as those from Ubbink and Klober come with their own flange to ensure a tight fit with the surface and maintain the insulation and water resistance of your flat roof. They are quick and easy to fit, either screwing in directly to existing pipework, or compatible with our range of adaptors to attach the flat roof vent to mechanical extraction systems.

All of the Ubbink and Klober roof vents we offer are thermally stable, UV and weather resistant, whether made from high impact uPVC, polyethylene, or TPE. And our range includes flat roof vent products suitable for use in all kinds of flat roof including PVC, asphalt, felt, and bituminous covered. So whatever your particular needs for ventilating your flat roof you can find the flat roof vent solution at Building Suppies Online, and at a great value for money price.
