Chimney caps protect moisture, birds’ nests, pests and dirt from entering the chimney. They are mesh-sided covers that protect chimneys and maintain their good condition. They are made from stainless or galvanized steel and copper. Rain or excess moisture can easily destroy brick or clay chimney walls if they are not secured with the device. Metal chimneys are made from two or three layers of steel or aluminum sheets with air insulation between them. Metal caps prevent damage to the material and maintains the effectiveness of the chimney.

Step 1 – Inspection

Carry out regular inspection on chimney caps by calling a professional or technician to check its condition. This can be done once a year and followed up by monthly check ups. It helps to maintain the chimney caps in good condition and also protects the house.

Step 2 – Find Out if They Are in Place

Strong winds or heavy rains can remove or blow of the caps from the chimney. Take a look at the devices regularly to ensure that the entire system is in place. Also watch out for damages which can be caused by harsh weather conditions. Replace the cap if necessary.

Step 3 – Check for Secure Attachment

Extreme weather conditions can loosen the cap from the chimney. If the device has been in place for a long time, it can also become loose with time. Regular inspection helps such faults to be corrected. If the chimney cap is loose, fasten it in place. Replace the screws or bolts if they are damaged or worn out. Chimney cap sealant can also be used. If the cap is damaged, replace it too.

Step 4 – Check for Rust and Corrosion

Chimney caps that have been in place for a long time might become worn out as a result of rust or corrosion. Most devices are made from galvanized steel or aluminum and they may last while in good condition for up to five years. In case a chimney caps is damaged by rust, replace it and secure it with new screws. Apply chimney cap sealant to secure it in place.

Step 5 – Check for Clogging

The mesh enclosures on the side of chimneys caps can get clogged or blocked by leaves, dust, dirt or debris. Soot or creosote can build up on the cap as well. Check for such blockages and clean them as soon as they occur. For dirt, creosote or soot, brush off the particles until the mesh is clean and clear. For leaves, remove the pieces and make sure the enclosure is clear from debris.
