Roofing materials are available in a wide range of shapes, sizes, textures, materials and colors. The selection of a particular roofing material depends on various factors like the needs of the area to be covered, durability, price and looks. If you want a roofing material which is durable, can keep off rains, allows drainage and does not block the passage of light, then corrugated fiberglass roofing is a very good option.
Corrugated roofing material is commonly used to cover areas, where you need a translucent roof, which can allow the passage of light and at the same time prevent heat. It is commonly used for covering backyards, patios, carports and greenhouses. Some varieties of these translucent fiberglass roofing sheets have inbuilt filters to prevent ultraviolet rays from passing through.
What is Corrugated Fiberglass Roofing
Fiberglass panels with the ridges and grooves pattern is called corrugated fiberglass roofing sheets. It is this pattern that is said to be responsible for the strength of this roofing material, though it is lightweight in nature. Corrugated fiberglass is mostly preferred for slanting roof, as there are chances of rainwater/snow accumulation in flat roof.
Fiberglass is a versatile material that has been used for various purposes, since the latter half of the twentieth century. As the name rightly suggests, fiberglass is nothing other than fine fibers of glass. Molten glass is extruded through fine holes to make thin glass fibers that are reinforced with different resins, so that the resultant product can be shaped as per requirement. Initially, this material was solely used for insulation purposes. But, now, it has a wide range of applications. It is being used in making water storage tanks to roofing, pipes, automobiles and boats. While fiberglass felts are used as a matting material for roof, sheets and panels made of this material are used as main roofing. In case of fiberglass roofing sheets, the high strength glass fibers are reinforced with plastic resins. So, this material is also known as glass reinforced plastic or GRP, which allows light to pass through.
Earlier these roofing sheets were available in white, green and clear types. Now, you may see them in almost all shades and designs. Most of you might have noticed the green-colored roofing in green houses, backyards and patios. While some of these are flat, others are wavy in nature. The wavy ones are called corrugated roofing.
Pros and Cons of Corrugated Fiberglass Roofing
Fiberglass roofing material, which was introduced in the late 1930s, gained popularity due to its low-cost, anti-rust properties, easy installation and translucency. People began accepting it as the perfect material to cover outdoor structures like yards, porches, greenhouses and carports. Corrugated fiberglass sheets became the most preferred roofing to cover barns and industrial buildings too.

~Fiberglass roofing material is not recommended in areas prone to high winds. If used in such areas, extra care needs to be taken to fix them firmly to the structure.
~Another problem with this roofing is that they offer little insulation from extreme heat and cold. You have to install a false roof beneath it for better insulation.
~Fluctuations in temperature can cause expansion and contraction of corrugated fiberglass roofing. You have to take care of this problem at the time of installation itself.
~Though they are shatter resistant to a great extent, corrugated fiberglass sheets may crack, if any heavy objects fall on them. This is another reason for people to avoid using this roofing material.
However, this type of fiberglass roofing is used by people as a cheaper alternative than the other costlier and heavier varieties of roofing.
