Things to Consider When Buying a Chimney Cap
1. Material
Galvanized steel is cost-effective and strong, while stainless steel offers better corrosion resistance—especially important in humid or coastal environments.
2. Flue Compatibility

4. Mesh Screen Protection
A fine mesh not only prevents birds, leaves, and pests from entering but also functions as a spark arrestor for added safety.
