What are chimney pot cowls?

Chimney cowls are covers that go over chimneys to keep birds, waste, and other pests out while also preventing smoke from blowing back into your house. JJ Roofing Supplies carries a large selection of cowls from industry leaders such as MAD Cowls and Colt Cowls. In addition, there are different types of chimney cowls available with us, depending on your requirements, including:


Birdguards are one of the most basic types of chimney cowls. They are typically mesh-shaped to keep animals out of the chimney space while still allowing air to flow freely in and out of the chimney.


Cappers are the go-to chimney balloon for straightforward and adequate protection. These easy-to-install caps keep out water to prevent long-term damage caused by prolonged moisture in your chimney block space.

Aspirator cowl

The Aspirator utilises a contemporary and stainless-steel design to provide an effective solution for improving the efficiency of the fireplace. This chimney cowl is designed like a turbine which allows wind to catch and rotate it rapidly. This creates increased air to draw up the flue liner resulting in better fire performance.

A chimney pot and cowl add visual appeal to any home with an existing or disused open chimney stack.
