Types of Chimney Pots


What to Know About Chimney Pots



Chimney pots might be overlooked, yet they fulfil important functions in both the performance and appearance of a chimney. They help in directing smoke and gases effectively out of the flue. Different designs provide distinct benefits, with the Roll Top, Sankey, and Tall Boy pots being some of the most common options.





The Roll Top Pot: Popular and Functional



Known for its rounded top, the Roll Top Pot is a familiar sight on traditional British homes. This structure is designed to prevent water entry by extending outward.



It is particularly helpful in mitigating downdraughts—unwanted backflow of air that can push smoke indoors. The pot’s shape acts as a natural barrier to wind, encouraging the proper direction of airflow.



Typically made from weather-resistant materials like terracotta or clay, Roll Top Pots are built to withstand the elements. Their unobtrusive design also means they complement a wide range of roof styles.





The Sankey Pot: Built for Strength



With its increased height and wider base, the Sankey Pot is a solid choice for homes with extended chimneys or multiple fireplaces.



This design supports strong airflow and efficient expulsion of smoke and fumes. It also lessens the chance of residue buildup, including soot and creosote, which can cause dangerous blockages.



Apart from its functional merits, the Sankey Pot brings a bold look to rooftops. It’s a wise choice for households that require high-capacity ventilation solutions.





The Tall Boy Pot: Streamlined and Capable



Slim and upright, the Tall Boy Pot is tailored for chimneys in areas where draught can be inconsistent. Its elevated form boosts natural draught, drawing smoke upward more effectively.



This type of chimney pot is ideal for situations where wind disruption can hinder chimney function. It enhances draw, thereby supporting performance.



Thanks to its slimline profile, it’s often favoured in properties where roof space is restricted. Its appearance also suits both period and newer builds without dominating the roofline.
