We offer a comprehensive range of roof vents, tile vents, and slate vents designed to suit most roof types and roofing materials. Our selection includes solutions for concrete roof tiles, clay roof tiles, slate roofs, interlocking tiles, plain tiles, and flat roofs, helping homeowners, contractors, and roofing professionals find the right ventilation product for their project.
Whether you need roof space ventilation, a vent for bathroom or kitchen extraction, or a solution to help prevent condensation and moisture build-up, we have products available in a variety of profiles and airflow capacities. Many of our vents are designed to blend seamlessly with existing roof coverings, providing effective ventilation while maintaining the appearance of the roof.
If you're unsure which vent is suitable for your roof type, our product specifications and technical team can help identify the best roof ventilation solution based on your roof covering, ventilation requirements, and extraction needs.

For a seamless and aesthetically pleasing look, our in-line tile and slate vents are a great option. We offer a variety of in-line profiles to match popular roof tiles (UB62), clay tiles (UB8), and slate roofs (UB11), giving you plenty of choices to suit your project.
Please note: Some in-line profiles have a lower free vent area, so if you're using them for extraction, ensure they provide adequate ventilation.

Check the back of the tile as some manufacturers will state the profile, if you are unsure please contact a roofer or send Ubbink UK a picture with dims and we can help identify.
Check the brand, type, and shape of your existing roof tiles. We offer vents designed to match specific tile profiles, as well as universal options. You can also measure your tiles and compare them to the vent specifications or ask a roofing expert for advice.
To determine the number of vents needed for a pitched or flat roof, divide the total required ventilation area (in square feet) by the free ventilation area of the vent you plan to use. This helps you find the total airflow needed and ensures you install the right number of vents for proper ventilation.
All Ubbink ventilators come with a 4mm grille/mesh to ensure there is no risk of access by any nesting animal to comply with British Standards and NHBC Standards.
The number of roof tile vents required depends on the size and design of your roof, as well as the level of ventilation needed. To calculate the number of vents, divide the total required ventilation area by the free ventilation area (FVA) of the tile vent you intend to use. This will determine how many vents are needed to provide adequate airflow throughout the roof space.
Correctly sized roof ventilation systems help control condensation, reduce moisture build-up, and maintain the long-term health of your roof structure. Ventilation requirements may vary depending on whether you are ventilating a cold roof, warm roof, loft space, or attic conversion, so it's important to check the relevant building regulations and product specifications. For the best performance, roof vents should also be evenly distributed to ensure consistent airflow across the roof.

The ventilation requirements of cold, warm and hybrid roofs are outlined within BS5250:2021. The ventilation strategy is determined by the roof structure, the roofing undelay used and the air permeability of the primary roof covering.
A cold roof is defined in BS5250:2021 as where the insulation in a pitched roof is placed on the horizontal ceiling and the roof structure and the encolsed attic or loft is colder than the internal occupied spaces
A pipe adaptor connects a roof tile vent or terminal to a duct or pipe, allowing proper airflow. You may need one if you're using the vent for soil pipes, mechanical extraction, or ventilation systems. Check your setup to see if an adaptor is required for a secure fit.
A warm roof is defined in BS5250:2021 as a roof where the thermal insulation is placed at or above the level of the rafters/roof structure, so that there is little or no ventilated void between the insulation and the underlay/covering.
Free Vent Area is the total unobstructed area within a vent opening which air can freely flow. Having a larger free vent area means less vents are needed to meet the local legislation saving cost to your project and install time.
The British Standard BS5250:2021 
A vent will allow natural ventilation into the roof void to meet BS5250 standards maitaing a healthy cold roof void. Terminals and connected to ducting offering supply or extract to an mechancial fan or system. There will be different requirements depending on the size of the roof and the output of the fan being terminated.
Ubbink supply many builders merchants throughout the UK. It would be best to contact your local merchant to see if they have stock or contact the relevant Ubbink Regional Sales Manager if you wish to purchase any Ubbink products.
