Rain gutters are a crucial element for any home. These tubes, attached to the roof edges, hold rainwater and divert it away from the house foundation to the ground. The absence of a gutter will cause the roof and walls of the house to get damp. So, these are a crucial element to keep your property safe and protected from moisture and its damage. However, even having a gutter system can lead to several issues, such as standing water in the gutters, which can cause seepage and result in various problems.
Why Water Stagnates in the Gutters?
Rain gutters are extremely essential to keep your property dry and safe from moisture-related damage. However, there can be various reasons why water can become stagnant in the gutters of a house's roof.
Clogged System
Often, rainwater or water from melting snow accumulates in the gutters due to a clog in the downspout. This is the most common problem that many homeowners face with their gutter systems. Several elements can lead to clogging of the downspout, like animal nests, golf balls, tree branches, pine needles, dry leaves, stray tennis balls, and many more.
When you have left the clog as it is, rainwater will keep on accumulating on the roof and will start damaging your roof slowly. Any clogs in the downspouts are quite difficult to detect initially. So, you can know about the clog only when the water has started getting stagnant. An expert can help in understanding the clog and developing a solution.
One of the best ways to maintain the cleanliness of the gutter system is to do it properly. Experts recommend cleaning the gutter system during the fall and spring seasons to prevent debris from accumulating in the system. When the downspout is free from debris, the chances of standing water in the gutter are significantly reduced. Additionally, one of the best ways to protect your gutters is to invest in a gutter guard, especially if you live in an area with surrounding trees. The guard will prevent debris from entering the system, thereby avoiding clogging. However, even with gutter guards, it is essential to schedule maintenance of the gutter system at least once or twice a year to prevent any potential problems.
The Slope
Among various essential elements of a gutter system, the slope of the system is the most important one. If the tubes are not installed at the correct slope, the water will not drain properly into the downspout. Often, when homeowners attempt to install a gutter system on their own, they make mistakes by installing it at the wrong slope. The wrong slope does not allow the water to flow smoothly, and ultimately causes standing water.
So, how do you know in the first place that the gutters are working properly to drain water smoothly? Check the gutter system work just after a downpour. If the water flowing is also gathering in a corner, you must know that the slope of the gutter system is not correct. You must immediately call an expert to discuss this issue and install the system again in a proper slope.
The expert will first try to realign the slope by correcting the hangers. But if this does not work out well, then the only solution left out is to change the entire system. The experts will suggest that you remove the entire system and then apply a new one or so accordingly.
How is Stagnant Water Harmful?
You may not have the time to inspect your roof and gutter system due to your busy schedule. So, you must check out the dangers that you are involving in leaving standing water in gutters. Here are some potential and major damages that you may have to face if you do not take care of your gutter system and let water stay in the system for a long time.
Pressure on Foundation
Standing water in gutters and on the roof will eventually overflow, and water will begin to flow near the house's foundation. The downspout is installed to throw the rainwater away from the house foundation. However, if the downspout is clogged or not aligned properly, causing water to overflow, it will begin to affect the soil near the house’s foundation. This will start causing many structural damages.
The whole house stands on the foundation and any damage to the foundation will cause damage to the house also. The water may start seeping in the basement of the house by creating cracks in the roof. You will know this when you start getting bad odour from the basement.
If you have already faced this problem, the next immediate thing that you must do is to take out the water from the basement and the foundation. You can do this with the help of a sump pump.
Settling Foundation
Even after removing the water from the foundation, you cannot always avoid the impacts of standing water. If the water has been present for a long time and has caused significant pressure, the foundation tends to shift and then settle accordingly. When such a thing happens, you will notice cracks on the walls as well as floors getting uneven. Not just the walls or the floor, the shift can even cause damage to other structures like the masonry chimney. Additionally, gutters that hold water for an extended period often develop cracks and other forms of damage. So, whenever you see standing water in the gutter system, you must not wait for it to start accumulating in the foundation. You must take immediate action when you notice standing water in the gutter system, because if the water starts to act against the foundation, dealing with the damage can become extremely difficult.
Mold in the Basement
Standing water in gutters for too long can also cause moisture to impact the basement. Moisture accumulates on the walls and ceilings of the basement, facilitating mold growth. The mold not only damages the walls and ceilings but can also cause several health issues for the people living in the house. Many people get respiratory conditions like asthma because of mold growth in the basement.
Mold growth and moisture can cause damage to the assets in the basement, including furniture, seasonal clothing, and other valuable possessions. So, standing water can cause significant damage at once. Why take the risk of all these issues when you can actually avoid them by taking care of your gutter system on a regular basis?
Pest Attack
Apart from mold, pests are another issue that can arise from standing water in the gutter systems. When pests like flies and mosquitoes start breeding in the accumulated water, they will start attacking you soon in your living area of the house. Mosquitoes can spread several diseases among family members, while some other flies and pests can infect the people of the house with several conditions like heartworms.
So, not only will the standing water in gutters impact the house, but it will also bring deadly diseases and health problems for the entire family. Therefore, if you do not want to risk the health of your family, you must ensure that you clean the gutter system regularly to prevent stagnant water.
