Our premium Lead Flat Roof Vents provide an elegant, durable, and effective solution for building ventilation and terminating soil pipe stacks and vent pipes. Available in three distinct styles—High-Top, Cone, and Dome—these versatile vents complement any architectural design whilst delivering exceptional performance.
Crafted from 100% recyclable sheet lead milled to British Standard BS EN 12588, our lead breather vents and mushroom vents combine traditional craftsmanship with modern sustainability for lasting quality.
The ideal vent for your flat roof depends on your specific requirements and aesthetic preferences. High-Top vents offer maximum airflow capacity, making them perfect for larger spaces requiring substantial ventilation. A Cone design provides excellent weather resistance whilst maintaining efficient airflow, suitable for most standard applications. For a more traditional appearance with reliable performance, Dome vents deliver consistent ventilation whilst harmonising with classic architectural styles.
All three options are manufactured from high-quality lead, ensuring longevity, weather resistance, and seamless integration with lead-based flat roofing systems.
Proper ventilation is essential for extending the lifespan of any flat roof system. Building regulations typically recommend a minimum ventilation area equivalent to 1/250 of the total roof area, strategically positioned to create effective cross-ventilation.
For flat roofs, vents should be installed at optimal intervals—generally one vent per 25-35 square metres of roof area, depending on the specific roof construction and local climate conditions.
Adequate ventilation prevents condensation build-up in roof voids, which can lead to structural damage, insulation deterioration, and mould growth. Our lead breather vents ensure proper airflow whilst maintaining watertight integrity, protecting your property from moisture-related issues while complying with building standards. For soil pipe terminations, regulations typically require proper ventilation above roof level, which our lead mushroom vents efficiently provide whilst maintaining an attractive roof-line appearance.
