Roof Ventilation

Roof ventilation is essential for maintaining a healthy roof structure and preventing condensation, damp, mould and heat build-up. Whether you’re working on a new build, refurbishing an older property or improving airflow in a loft space, the right ventilation system ensures long-term performance and protects your home from moisture-related issues.

Roof Tile Ventilation for Effective Airflow Through Pitched Roofs

Roof tile ventilation allows fresh air to circulate beneath roof coverings, reducing condensation and preventing moisture damage. These discreet vents are designed to blend seamlessly with standard roof tiles while delivering efficient airflow. Roof tile ventilation is ideal for loft spaces, roof voids and pitched roofing systems that require consistent ventilation.

Roof Slate Ventilation for Natural and Heritage Roofing

Roof slate ventilation provides discreet airflow solutions for natural slate and fibre-cement slate roofs. Designed to match traditional roof aesthetics, these vents maintain the appearance of slate while improving roof space ventilation. Roof slate ventilation is perfect for heritage properties, conservation areas and high-quality pitched roofing.

Roof Outlets for Soil Pipes, Extraction and Ventilation Ducting

Roof outlets ensure safe and effective ventilation for bathrooms, kitchens, extractor fans and soil vent pipes. They maintain airflow while preventing rainwater ingress and protecting the roof surface. Roof outlets are available in various profiles and colours to suit tiled, slated and flat roof installations.

Flat Roof Ventilation to Reduce Condensation and Moisture Build-Up

Flat roof ventilation systems are essential for avoiding trapped moisture in warm and cold flat roof constructions. These vents help regulate airflow, minimise condensation and protect insulation layers. Flat roof ventilation is suitable for garages, extensions, commercial buildings and modern single-storey homes.

Fascia & Soffit Ventilation for Continuous Eaves Airflow

Fascia & soffit ventilation ensures a steady, balanced airflow entering the roof space from the eaves. Continuous vent strips, circular vents and over-fascia options help reduce condensation and improve overall roof health. Fascia & soffit ventilation is vital for creating a complete, breathable roof ventilation system when paired with high-level vents.

FAQs

Why is roof ventilation important?
Proper ventilation helps prevent moisture build-up, mould growth and structural damage, extending the lifespan of your roof.

Do I need both eaves and high-level ventilation?
Yes — combining fascia & soffit ventilation with tile or slate vents creates balanced airflow and reduces condensation risks.

Are roof outlets suitable for extractor fans?
Absolutely. Roof outlets are designed for safe, weatherproof extraction from bathrooms, kitchens and internal ducting systems.
