It is installed in every corner of the house, since it is better that the gutters do not run around the corners of the roof, but they can also be added anywhere under the roof. They are attached to a hole in the bottom of the gutter, a connecting piece is placed inside, and then secured with glue or screws. Directing a downspout around a corner is a fairly simple process with the right materials. The corner turn itself requires elbows of 3 to 90 degrees in a basic installation (2 elbows in B and 1 elbow in A).
If more distance is needed, extension sections of the downpipe can be placed between the elbows. There are a few factors that need to be considered when determining where to place gutter downspouts. First you should consider how many downspouts you'll need. The typical recommendation is one downspout for every 20 to 30 feet of gutters.
The next factor to consider is the slope of the roof, since the slope will cause water to flow in a certain direction. Channels and downspouts must be installed with this inclination in mind so that water flows downward instead of remaining stagnant in the gutter channel. Finally, you should think about the design of your home: gutter downspouts should not be emptied near a mezzanine, a basement window, or any other place that could allow water to seep inside. Having downspouts at both ends depends on what the landscape looks like; maybe there is pavement or other elements where you don't want water.
With gable roofs you can have a gutter system with quite a few corners. Every time the water rotates in a corner, it slows down. Therefore, the number of corners can also affect the number of downspouts. Even if the gutters are properly tilted and the downspouts are in the correct position, overflow could still be a problem due to leaves, twigs, bird nests, and other debris reaching gutters and downspouts.
A house with several peaks and valleys is more of a challenge than a straight roof line, but a professional gutter contractor can ensure that your gutters and downspouts are installed correctly. While most people know what gutters and downspouts are, few people know that there are other accessories that can be installed in a gutter system to make it more effective.
