For steep residential roofs, gutters are necessary in order to stop water from causing foundation damage. While it's possible to get a professional to install a new rain gutter system, this job is completely doable on your own. You just have to make sure that you watch out for these three common mistakes people make when installing rain gutter systems.
Not Getting Pitch Exactly Right
In order for water to flow smoothly from your roof into the gutter and down the downspout leading off into your yard, the gutter's pitch needs to be slanted a very small amount. If it's straight, water will pool on the gutter for much longer before going down the downspout. The extra weight from the water will lead to maintenance issues down the line.
Too much of a slant relative to your roof will make the gutter less stable structurally, increasing the risk of it falling off in a storm. Therefore, it's important that you put a lot of effort into getting all of your gutters' pitches exactly right.
Putting The End Of The Downspout Too Close To Your Home
The whole point of a gutter system is so that rainfall won't pool in the immediate area around your home and cause foundation issues. So when you're figuring out where your downspout is going to lead, ensure that it stops reasonably far away from your home.
This doesn't mean, however, that you should lead the water as far away as possible. It's also important that the immediate area around the end of the downspout is free enough to take on a lot of water. Nearby sidewalks, concrete porches, and external AC units all get in the way of this.
Screwing The Downspout's Braces Too Tightly
Downspouts are commonly supported with a series of metal braces attached to walls. While it's important that these braces are tight enough to prevent your downspout from wobbling, too tight of a fit will squeeze the pipe and actually increase the risk of a rupture during a storm.
The larger your home is, the more strain that your gutters and downspout are going to be placed under. Downspouts spanning multiple stories should have the tightness of their braces examined with special care. Even after your installation is complete, you should subsequently check the braces again at least once to ensure that there's no warping damage.
A rain gutter system is an important part of supporting and maintaining your roof. If you're serious about avoiding unnecessary trouble with your roof, it's important to ensure that you aren't making any big mistakes with your rain gutter system installation.
