Think Your Chimney May Be Leaking?

What Makes a Chimney Leak?

One of the biggest reasons of a chimney leak is faulty flashing. Issues with the flashing is normally down to basic wear and tear, improper installation or simple corrosion. Flashing issues can be determined with the help of a low pressure hose that sprays water around the chimney to the intersection of the roof. If water is present, this is a strong indication that repairs have to be done.

Making sure the flashing is done with top quality material which is resistant to leaks is an excellent way to stop them from happening. Lead is usually the best material to be used for flashing; however, lead coated copper or just plain copper will also stop leaks as well. Though cheap, aluminium comes with an extremely high corrosion rate and should never be used as flashing. Plus, flashing needs to be correctly installed using the step fashion, this means using 1 inch slots. Some property owners should steer clear of gluing flashing to the brick, mostly due to the fact it has a propensity for leaks.

Another thing which could lead to a chimney leak is the top. If the top is loose or cracked, this will cause leaks, and several gallons of water will pool inside. When performing an installation, it is better to use bricklayers that will fill the insides of a chimney with brick and mortar, thus preventing cracks and crevices from happening. When building the last 1.52m, bricklayers can be told to use non porous hydraulic cement as mortar. If the homeowner is experiencing a leaky chimney on one which is already installed, they should consider using lead coated copper sheeting to cover the it to stop water from entering.

Crickets can be installed as well. They divert the flow of water, thus ensuring the chimney’s structure and flashing are not badly impacted by water being present.
