The Ventilation - Roof Fans category provides a wide range of units designed to extract stale or humid air directly through the roof while maintaining weather protection and performance. These include roof mounted extractor fans, axial roof fan models, turbine roof fan options, and roof ventilator units ideal for lofts, bathrooms, kitchens, or industrial roofs. Whether you need a compact roof fan cowl unit or a high-capacity roof exhaust fan, this category caters to both residential and light commercial applications. Here is what’s available in this selection:

• Roof exhaust fans – high airflow units for kitchens or large utility areas where strong ventilation is required.
• Weatherproof roof fan systems – units built to resist rain, snow, and moisture with durable cowl covers and corrosion-resistant materials.
• Roof ridge ventilator fan options – fitted along the ridge of pitched roofs for passive or powered extraction.
• Turbine roof fan variants using wind to assist airflow, reducing energy usage when used alongside powered extraction.
• Roof mounted extractor fan with timer, humidistat or overrun functions to manage moisture, odours and condensation.

Many DIY users or tradespeople wonder “how to install a roof fan”, “which roof fan units are best for pitched vs flat roofs”, or “roof fan sizing for airflow needs”. The products in this category provide clear performance specifications such as airflow (l/s or m³/h), power ratings, and ingress protection for safe outdoor use. Roof ventilator units often include features like built-in shutters to stop backdraughts, sealed bearings for quiet operation, and cowl designs that help weather protection. Using an appropriate roof exhaust fan or attic roof fan can dramatically improve indoor air quality, reducing damp, mould, and condensation in lofts or ceiling voids. For kitchens or bathrooms, roof fans help remove cooking odours and moisture at source. Roof mounted extractor fans are especially useful where walls are not available for venting, or where ducting directly up through roof ones is required. This roof fan range is suited to both new build and refurbishment projects. If you need a roof ventilator unit, axial roof fan, or weatherproof roof fan that delivers reliability, durability and performance, this category delivers what you need.
