How Blocked Gutters Can Damage Your Home.

Your gutters don’t get the consideration they deserve. We usually think that a gutter’s only function is to make sure that water that falls on your roofs ends up in your drain, and while that is true, it’s the reason why this function is so important to makes it imperative we ensure that our gutters remain in tip-top shape.

Here are a few things around the house that might get damaged if your gutters remained blocked.

Yours Gutters.

Gutters are designed to move water from one place to another, but when the gutters are blocked, that water has nowhere to go. And even if the water evaporates, the blockage itself will remain water-logged for even longer. Water is heavy, and gutters weren’t designed for dealing with heavy weights that don’t move on. Eventually, your gutters will sag and may even fall away from your roof.

Your Roof.

If your gutters are blocked, the water will eventually overflow the gutters. Some may flow down your walls (more on this later), some will pool on your roof. Like gutters, roofs aren’t designed to hold heavy bodies of water for long periods of time. It’s why roofs are slanted; it’s to get water off the roof. In time, the roof might rot, or buckled under the weight of the water. If you’ve noticed your roof continually leaking, it might be because your gutters are blocked.

Your Foundations.

Pretty much all of the damage caused by blocked gutters is because the flow of water is not being controlled. Gutters are supposed to control the flow of the water from the roof down into your drains. If that process is blocked, the flow of water becomes unplanned, and that’s where damage can occur.

As mentioned previously, some water may overflow the gutters and form standing puddles on the roof; some water may flow down your exterior walls and form standing puddles near your foundations. This water can cause erosion at the base of your walls, which weakens the structure of your foundation.


Gutters blocked with water-laden vegetation and debris attract insects, like disease carrying mosquitoes. if you have leaks into your house, those mosquitoes have an easy passageway into your house, and once inside, you become their favourite food source.

If your roofs are leaking, that water coming inside also invites mould growth to form. Mould spores are particularly dangerous for those suffering from asthma or allergies, which are far more prevalent in the young and the old.

All in all, there are many reasons why you should have your gutters regularly cleaned by a professional gutter cleaning company. Perhaps you could do the cleaning yourselves, but please consider the fact that working from ladders that are placed against gutters that may be compromised because of the blockage, may cause you to have an accident and fall … and falls from even a couple of feet can be dangerous, while falls from a couple of metres could be fatal.
