If you are planning to build a pergola you may have considered attaching it to your house. Depending on your architecture, this can give you a great old world look or a crisp and modern touch. It’s a great detail to have your pergola adjacent to your home. However, what if you have gutters? You may be wondering how to attach a pergola to a house with gutters. In this article, we’ll discuss a few options that you have with pergolas.
Pro Tip: Consider A Self Supporting Pergola
First there’s the obvious solution, don’t attach the pergola to your house. It’s not uncommon to build pergolas which are next to the house, but don’t attach. If you are planning on a wooden or cellular PVC pergola which has fixed slats and are always open to the weather, there’s no need to connect to the house. This way your pergola would be a self supporting structure, next to the house and the gutters and roof trim can remain independent like the photo below:

The next option for how to attach a pergola to a house with gutters is to build an aluminum kit pergola. There are two major manufacturers of these pergolas, Struxure and Apollo, but there are more coming on the market every day. The main benefit of using one of these pergolas is you have motorized louvers. This means you can have an open pergola when you want to be able to see the stars or let the sun shine in. Also, when the sun becomes oppressive and you need to escape, you can close the louvers and create a solid roof.
Aluminum motorized pergolas have built in gutters and drainage systems. This allows the water to run off the pergola louvers into downspouts built into the pergola posts. These built in gutters could handle roof runoff in addition to the rainwater landing on the pergola. However, you’ll need to provide the pergola manufacturer with the dimensions of the roof which will be draining onto the pergola. In doing so, you’ll make sure they factor in the flow rate when designing the drainage system.
