A drizzle of rain can always bring relaxation from the hot climate or can create a romantic mood. But when the rainfall is higher, it also causes concern. In Portland, the usual average rainfall is 24 inches, but the highest rainfall can go to 47 inches in some regions. When the rainfall is high, it can concern most of the Portland homeowners. Gutter extensions in Portland are getting popular these days because homeowners are becoming more responsible for their roof gutter conditions.
Most homeowners in Portland take extra care of their roofs with regular inspections, timely cleaning, and proper maintenance procedures. But also some of them have gone the extra mile by investing extra features to the roofs like a roof gutter guard or a gutter extension. While a gutter guard protects the gutter from any debris, the gutter extensions in Portland control the water flow and allow the water to flow away from the house’s foundation.
Of course, you must install the features depending on the amount of rainfall in an area. So, if you reside in Portland, you must contact a gutter company to understand whether investing in gutter extensions in Portland will be the correct decision for you or not.
Importance of Gutter Extensions or Downspout Extensions
When heavy rainwater pours on a basic gutter system, there are chances of the water overflowing and destroying the property’s foundation. A gutter extension or a downspout extension is fastened to the gutter system to collect any extra water and deviate it to the downspout outlet for drainage. When you have installed a gutter extension, you will always stay away from the risk of overflowing that might otherwise damage the house’s foundation.
So, what is a gutter extension or a downspout extension?
A gutter downspout is a pipe attached vertically to the gutter system, to carry the water from the gutter and drain it away from the house. In the absence of a downspout, the water may clog the roof gutter and then it may overflow causing dampness and damage. But at times, even when you have a downspout, the water may overflow and this is the time when you require downspout extensions. The gutter downspout should be installed at least 4 feet away from the house so that the water drains far away from the foundation.
So, the downspouts are installed to collect the water from the roof gutter and empty them at a spot that is away from the house foundation. However, a downspout is not always helpful in saving the ground near your house base to become a marshland. This is the time when you require an extra addition to your gutter system in the form of downspout extensions.
Also, water damage because of snow or rain does not occur in just one day. Often if there is a clog in the gutter system, the continuous rainfall or snow of a few days will accumulate on the roof, causing the damage. Not only, there is a risk of water overflowing, but also the accumulated water leads to damage to the roof and walls. Such damages can cost you dearly in terms of repair or even at times replacement of the whole gutter system and some parts of the roof.
Apart from the gutter system, the roof’s slope and the soil are also a major consideration. Rain gutter extensions are also a great way to prevent soil erosion and foundation damage because of the wrong slope. For example, if the downspout is installed in the wrong position, water can seep from the sides of the downspout. At the same time, if leaves and debris have clogged the downspout, water will not find space to flow freely and will cause leakage and damage. Also, the water will cause extra weight on the gutter system, often leading to damage or cracks in the system. Of course, mold and other structural issues are some other problems that you may have to face if you do not consider a gutter extension for your system.
When do you need Gutter Downspout Extensions?
The need for spout extensions does not arise in a single day. You will notice the need to have an extension over a couple of weeks or even months. Here are some major red flags that you will come across as to why you must invest in downspout extensions in Portland.
- Debris, leaves, pebbles, and other elements are clogging the gutter system quite often
- Continuous leakage from the gutter
- Mold growth on the roof, walls, and other areas of the house
- Damp feeling in the attic
- Leakage issue on the foundation
- Issues of soil erosion near the house
- Continuous damage to the landscape surrounding the house
- Nearby plants spoiling up because of excess moisture
If you notice all these signs, you should not ignore them and immediately call upon the experts to check whether you require gutter extensions in Portland for your gutter system or not.
How to Install Downspout Extensions?
Excess water spillage from the gutter will not only cause damage to the roof, walls, and the house’s foundation, but also to many nearby elements, such as the landscape and nearby plants. So, you must have a proper gutter system for your house along with a proper downspout outlet to allow the water to drain out properly away from the house’s foundation. Also, you must invest your time and money in regular investigation and maintenance of the gutter system. If you continue to experience issues, consider installing a downspout extension to enhance the system's performance. An extension will add a downward slope water far away from the house’s foundation. You can install spout extensions under porches, decks, or patios to prevent excess water from damaging your garden or causing soil erosion.
You will require an elbow to attach the extension to the downspout’s end. The extension is mainly a pipe that increases the length of the downspout so that the water drains out at least six feet away from the house’s base. But just installing downspout extensions is not enough. You must carefully calculate how and where to install the extension. Water can, at times, trickle from the extension to a slope, causing further damage. If you install the extension towards a slope, then the water can run towards the house’s foundation, causing damage. Also, do not install the extension towards the driveway or sidewalk. Water in the extension will freeze during the winter, but when it starts melting, it will start flowing towards the driveway, causing a slippery surface or any other damage.
Additionally, ensure that the area where you are installing the downspout extension does not have any ground gaps. If there is a gap in the ground, water will fill up in the gap, causing damage and issues. One of the best ways is to inspect the whole area and fill up any gaps with granular soil. Also, ensure that the extension is securely fastened to the downspout’s mouth to prevent any leakage. If the joining point is tight enough, there will be no leakage, ultimately preventing any water from anywhere from rushing to the building’s foundation.
Therefore, there are several things to consider when installing rain gutter extensions. One of the best ways to install downspout extensions in Portland correctly is to contact an expert who can do the task for you.
