Notching: Another important point to consider is notching. Notched pergolas last for longer times and have greater wind resistance capacity. So. while buying wooden pergolas. ask their manufacturers if they are partially notched or fully notched. Buyers should be aware that notching creates interlocking joints and this fortifies the structure. Also notching insures that all your timbers stay straight and true over the decades because they cannot move. Most manufacturers skimp on notching partially or completely to reduce their construction costs and will tell you that hardware will take care of the issue. It does not. If just one of your Pergola`s timbers has hidden stresses in it (quite common). as it weathers over the years. it will turn. twist or sag. This will cause your beautiful Pergola`s lines to be ruined.
Which shape do the pergola plans give your pergola? Finally. you will also have to make a choice between different shapes of the pergola. For example. many people like to have round pergola designs because of the way it looks while many others avoid round pergola designs because they are especially expensive to build. The easiest shapes for pergolas are square or rectangle.
Pergola - Roofing Options. Pergolas have been used in dwellings for centuries. classically. to add a shaded walkway. to link pavilions or to allow a sitting area which allows the breeze and sun to filter through. This amazing addition to a home will not only add to comfort. it can be an attractive bonus to the resale value of the home. Any open space around the home may be used as an invitation for a pergola. Over the years. pergola structures have adapted to the area so that there is a large variety in designs. While traditional pergolas were intended mainly for beauty and comfort. the current designs place more emphasis on providing protection from the harsh elements of nature such as rain and snow and ultra-violet radiation.
The roof design on a pergola depends on the availability of direct sunlight as well as the geography and natural features of the region. Although. in earlier times. pergolas were constructed using brick and stone pillars. modern designs employ weather resistant woods such as western red cedar or coast redwood. Pergola roofs may range from simple. flat. traditional roof. elaborately curved roof. pitched roof. gabled roof or a gazebo style roof.
