Pergolas can either be freestanding or attached to a house. These create a shaded or semi-shaded space. The roof is traditionally flat, and they tend to have more vertical posts than arbours. The roof of a pergola can be left open or covered with a waterproof fabric. They are intended to offer some shelter, particularly from the sun.

Wind protection is also very important. A high quality pergola that’s correctly put together should be stable and strong. Freestanding pergolas tend to be less wind resistant than lean-to pergolas, but unless you live in an extremely exposed area, both styles are considered appropriate. Once you’ve got the potential dimensions in mind, use markers to work out where the corners of the pergola will go. It will only offer protection from light showers. There are drainage holes in the canopy to prevent it from getting weighed down and damaged if there is heavier rain. Just be warned that these drainage holes can drain onto you if you are trying to sit under the cover during a heavy rain shower! One of the best things about this pergola is its wind resistance. The powder coated crossbeam is very stable and the posts have pre-drilled holes for securing them to the ground. It’s been reported to hold its own well in windy gardens. Pergolas are usually made from either wood, vinyl or aluminium, and there are pros and cons to each of these materials. Wooden PergolasThere are many benefits of buying wooden garden pergolas, below we provide two sets of benefits – for with or without a roof. Benefits of garden pergolas without a roof The Palram Canopia Sierra Aluminium Lean-To Pergola has a lean-to design instead of being free-standing. Lean-to pergolas make use of an existing wall and are a great option for putting near patio doors and extending your living space. This pergola projects 3 m outwards from the wall, with a width of 4 m. The roof is slanted, providing shade underneath even when the sun is low, while also allowing rain water to run off. For classic, English country garden style choose a round or hexagonal pergola made of wrought iron. Don't forget a pergola can also be covered with climbing plants. Powder-coated steel has the advantage of being lightweight and corrosion-resistant, although you will have to take care to avoid scratches. Steel can add a contemporary edge to the structure and your garden décor as a whole.

Roof styles vary as well. For a good combination of affordability, versatility and shade, I recommend an adjustable fabric canopy . These are usually made from polyester. Adjustable fabric canopies can be used to create full or partial shade and are easy to alter. They are usually shower resistant, so should protect the interior from light rain. Aluminium pergolas are available in a range of sizes. The most popular size option for domestic gardens is 3 x 3m. This is generally spacious enough for a coffee table and a few chairs, or a small dining set. You can fit around four to six people under a 3 x 3m pergola.
