What Is A Cantilever Pergola And Is It Right For Your Yard?

Are you considering installing a patio roof for your backyard? A cantilever pergola might be what you're looking for — but what is it? In essence, it's a particular style of pergola that provides shelter from the elements and typically comprises supporting beams, posts, and rafters. These beams help support the top rafters to create an open-air lattice-style roof that provides a shaded space in your yard. Aside from the practical benefits, a cantilever pergola can add structural design to your backyard — especially if you're into more of a bohemian or rustic vibe. 

What separates a cantilever pergola from a regular pergola is that in its design, a cantilever pergola's rafter sits at a certain angle that overhangs and goes beyond its main supporting beams. This specific type of design creates a bespoke finish and acts as a standout feature for your backyard while adding to the overall aesthetic of your outdoor space. In most cases, a cantilever pergola is a freestanding structure but can also be attached to a building, where possible.

Typically, a cantilever pergola is best suited for an outdoor deck as it's an ideal platform for it to be installed onto. With a cantilever pergola added to your outdoor space, you may feel compelled to spend more time outside with family and friends. In addition to the benefits of enjoying more time outdoors, it's also likely that the value of your home could increase — so it's a worthwhile investment all around.

However, while cantilever pergolas are most suitable for outdoor decking, a few exceptions exist. For example, concrete patios or other in-built outdoor bases can support a heavy structure like a pergola. Grass is not traditionally a go-to base for a cantilever pergola installation as the foundation may not be strong enough to support it long-term – although this is not always the case. As with any major outdoor structure, it's imperative that you seek out advice (either in the form of a contractor or a DIY specialist) before contacting a building inspector to seek approval. 

The most popular type of cantilever pergola tends to be those made from hardwood or plywood, as these materials work well in most backyard designs, especially if you already have a wooden deck to complement it. Other materials used for cantilever pergolas include vinyl, aluminum, and, in rarer cases, glass — although it's worth doing your own research if you're considering this material. Ultimately, whatever material you decide on, just be sure to take the time to decide what looks and fits best for your home.

Before taking the plunge into the proverbial pool of cantilever pergolas, it's essential to ask yourself a few key questions. For example, do you have a clear budget, and can you afford labor and materials — or is DIY better for you? Do you know which orientation you'd like: is the sun north, south, east, or west of your home? Do you want to hire a contractor, or is a pergola kit a better option? Do you know the correct building codes, and have you reached out to a planning commissioner? Do you know the right zoning laws for your area? Or do you need to contact a professional for advice before proceeding? Once you've got clarity on your specific needs, you'll be in a much better position to start building your dream cantilever pergola – no matter which path you decide to take.
