By Sally Delacruz


One good reason why you would want to have capping for chimneys is to prevent animals from entering inside chimneys. Small creatures such as raccoons, squirrels, and snakes can climb on the roofing top and access chimneys from above. Covering the top part of chimneys can help prevent such animals from entering the smokestack. Consulting a chimney caps Virginia Beach installer is a good idea if you want to protect the smoke extraction structure.

The chimney system consists of many components including the stack, flue, liners, dampers, and caps among other parts. For the smoke and gas extraction system to function properly and last for long, each component should be working properly. Without a cap, moisture will enter chimneys and quickly find its way into fireplaces, stoves, and walls or ceiling of a building.

Flue liners inside chimneys can suffer from corrosion and rust when they are exposed to excessive moisture. When it rains and the smokestack is not covered with a capping material, the water will enter chimneys. The effects caused by water in chimneys are ravaging. The smoke extraction structure will experience unexpected dampness, which acts on the walls and liners.

Remember that masonry work and moisture do not get along quite well. Cracks can form on bricks and mortar, and soon you have to replace the damaged sections. Cracked chimneys will leak gases and smoke to other areas of a house.

Downdrafts may also cause blasts of cold air to flow inside a house. If you fit cap covers on chimney tops, you will stop the downward blast of cold air making the house more energy efficient. As technicians fit the capping accessory, a protection wire mesh is also installed, which serves as spark defector.

Before you discover if your capping material is damaged, you will have already suffered other damages from moisture. The presence of moisture in chimneys can result to formation of acidic compounds. The moisture will mix with creosote and other substances that have accumulated on walls of flues. The acids begin eating away the walls including the flue, brickwork, and mortar.

However, at times, the wire mesh traps creosote and it becomes clogged with debris thus needing proper cleaning. If the top part of smokestack is blocked, there is insufficient supply of oxygen since it is cut off. You will have difficulties when start to burn logs, and they will not burn properly. The capping structure could also be blocked by the building creosote and debris and thus needing removal.
