Keeping Water Out of Your Chimney and Your Home


It looks like it’s going to be a wet week in Houston… again. According to KHOU, There's a 40 percent rain chance on Tuesday and it will climb to 50 percent through the rest of the week. The good news is that with all of the clouds, temperatures will stay in the mid-80s for daytime highs instead of the 90s.

The bad news is when it rains your roof and chimney will get wet. If you have masonry chimney that leaks, water ends up in your home. Why does a masonry chimney leak in the first place? Over time as brick chimneys are exposed to the elements (rain, wind and water), bricks and mortar chip and deteriorate allowing water to enter the chimney. Another reason that chimneys leak is because the flashing which is attached to the chimney and roof gets lifted up or rusts. Water can enter directly through the opening of the chimney gradually seeping into the roof joints and into your house, ruining drywall, causing wood rot and mold growth.

As a homeowner, what can you do to make sure this doesn’t happen? You can fix or replace the worn out bricks and mortar. You can also change the metal chimney flashing. But if you want to prevent water from entering through the opening of the chimney you’ll need a chimney cap or a masonry chimney crown.

By installing a chimney cap you’ll save yourself the expense of chimney water damage and eventual chimney replacement. Water damage causes over $1 Billion in damages every year. This damage can be avoided in the first place by a little preventative maintenance once every 5-10 years. A chimney cap can keep your fireplace safe from the elements and prevent animals from nesting in your chimney. So what are the different types of chimney caps and how are they different
