What is the difference between a cap and a cover?
A cap only protects your flue opening or chimney opening. It does a good job of preventing pests from entering your home. However, it does not protect the top of your chimney or crown wash. A full size cover will keep all weather out of the chimney and protect the top of your chimneys crown wash.
An uncapped chimney: It Is Bad News, here’s why:
• Says “come on in, make yourself at home!” to birds and animals.
• Allows rain and snow to enter your chimney, which leads to the metal damper rusting out.
• The combination of high heat and water speeds up the deterioration process.
• Creates a fire hazard as burning embers and sparks escape through the open chimney and land on your roof or in your yard.
