GARDEN AND YARD DECORATION

The design of a pergola depends on the geographical location. One of the most important considerations when designing a pergola is the roofing structure and shape

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.

Roofing materials

There is a variety of materials that may be used to roof a pergola. The choice of roofing materials depend on the size, shape and style of the structure. Currently the materials that are used for roofing include metals, plastic, fibreglass, polycarbonate, fabric, etc.

Metal Roof, Plastic and Fibreglass. Another variation of roofing for pergolas includes using plastic or fibreglass.

Polycarbonate. Polycarbonates are also highly reputed for their protection from ultraviolet radiation.

Fabric

The choice of materials to cover or roof the pergola depends on the buyer’s instincts as to the choices for durability, permanency and availability. White roofs reflect better. As the Earth seeks to get greener, the best choice, of course is to enjoy traditional, open roofed pergolas.

Painting your Pergola

Paint is also beneficial because they prevent moisture damage and rust. Acrylic paints are the best choice for painting pergolas as they provide the best protection.

The durability of pergola depends on the materials chosen for its construction. As the roofs are permanently exposed to the elements of nature, the paint chose may fade easily. Also, materials such as fabric may fray or fade and plastic or fibreglass roofs may get warped or change colour.

To paint a pergola for lasting protection, it is important to follow the traditional procedures such as preparing the surface which include removing old paint, using sandpaper to permit absorption and applying preservative towards the end of the painting. Application of a water repellent preservative with fungicide is an excellent idea before painting because it prevents absorption of water by wood which may cause decay.

Here are the steps to paint a Pergola:

• Also wear an apron or old clothes to protect from paint splashes.
• Using sand paper, remove all paint until the surface is completely prepared.
• Apply a water-repellent and fungicide if necessary.
• Use a paint roller to get a smooth finish.
• Give a light coating on the roof of the Pergola.
• Apply a second coat of paint on the roof of the pergola.
• Allow the paint to dry overnight.
  

Causes of Discoloration of Pergola roofs

Over time, Pergola roofs may get discoloration due to dirt, fungus, mildew or moisture. Restoration painting necessitates cleaning by paint strippers, bleachers and oxalic acid based solvents to remove stains.

How to Select the Best Roofing for Your Pergola

There are a number of different types of roofing available including polycarbonate, colorbond steel, tiles and opening roofs.

There are a few ways around this problem, firstly you can use a combination of polycarbonate and colorbond steel incorporating 2 or 3 sheets of polycarbonate inserts and having the rest of the pergola roof in colorbond steel. Some polycarbonates let more light in and others less heat. With excellent insulation properties this style of roofing is often used for cool rooms. Of all the pergola roof coverings this one will keep out the most heat. The only downside is that it’s extremely hard to install light panels into this type of roofing.

Depending on the type of materials and roof design of your pergola it’s often possible to change or reposition some of the roof sheets if your pergola is too dark or too hot.
