You must inspect the chimney cap often, to assure it still does what it’s supposed to. A general inspection should be carried out at least once a year. Regular, monthly checks on the cap are also recommended.
Rough weather conditions like strong winds or heavy rainfall can damage and even blow off the chimney cap. You must be sure that the cap is placed properly and can withstand any conditions. If the cap is damaged, you need to replace it.
The screws or bolts that keep the chimney cap into place might have been loosen over time, mainly because of rough weather conditions. Be sure to tighten any loose screws or bolts and use chimney cap sealant.
Rust and corrosion
Over time, a chimney cap will suffer from either rust or corrosion. In the case of galvanized steel and aluminum caps, the lifespan is longer than for other types of caps, of about 5 years. Any damaged cap needs to be replaced. The new cap must be secured in place and sealed.
Debris like leaves, dust and dirt can clog up the mesh enclosures of the chimney cap. Also, clogging can occur due to soot and creosote build-ups. You must remove the debris and brush the area in order to properly clean the mesh enclosures.
Keep in mind that safety is important. When performing maintenance on the chimney cap, secure the ladder and pay attention to what you are doing.
