Water Damage From Rain Gutters May Cause Mold Growth in Home or Building

Mold and Water Stains on the Ceiling

What in the world would rain gutters have to do with mold inside my home!  Mold needs water to grow. When the rain gutters and downspouts get blocked, the water can’t flow away from the roof line and your building. Water flows along the path of least resistance and you don’t want that path to be under your roofing materials or inside your walls.

If your rain gutters are clogged or draining slowly the water can overflow the gutters leading to water running down the sides of your building. This can lead to puddles forming up against the outside walls of your property.  If the rain gutters are clogged, water can pool up at the roof line. Areas of your roof that are not sealed well enough may allow the water to seep through the roofing material and into your attic and walls. Once the attic and interior walls get wet, the opportunity for mold to grow is present. Even though we think of our walls as being a barrier to the outside environment, water can soak through and get into the wall cavity space and then to the inside of the building. If this is already your situation, we can help!

Pine Tree Needles Clog Rain GuttersMaintenance is key in helping to prevent mold growth inside our buildings and homes!

Just a couple of weekends ago, I was doing some yard work and decided I should check out the rain gutters since rain was in the forecast. I live in southern California and we haven’t had much rain so I hadn’t given the rain gutters any thought since last winter. Our neighbors pine tree had been shedding pine needles like crazy and our liquid amber trees Tree Leaves Can Cause Mold & Water Damageleaves were turning the beautiful colors of fall. Well, my rain gutters near the pine tree were so stuffed with pine needles the gutters were over flowing with needles and the downspouts were completely covered up.  If that wasn’t bad enough, when I went to the other side of the house, the downspout had come off of the gutter completely and was just hanging there.  Even though I am on that side of the house frequently, I guess I never looked up!

Once again, I need to follow my own advice. My rain gutters are not very accessible to clean out so I will need to hire someone to take care of that.  It looks like a tree trimming is in order as well, sounds like 2 jobs to be hired out to prevent a mold problem insideThe cost of this maintenance will be much less than a costly mold remediation project.
