Types of Fiberglass Roof Panels

When it comes to fiberglass roof panels, there are various types available to suit different roofing needs. One popular option is the corrugated panel, which features distinct waves or ridges. These panels are not only aesthetically pleasing but also offer several advantages.

Corrugated fiberglass panels come in different profiles, allowing you to choose the one that best fits your requirements. Some common profiles include:

  • ⅞” corrugated
  • ½” corrugated
  • R panel
  • 7.2 panel
  • AG panel

Each profile has its own unique features and benefits. For instance, the ⅞” corrugated panel is known for its strength and durability, making it suitable for a wide range of applications. The ½” corrugated panel, on the other hand, offers a more lightweight option while still maintaining strength. R panel is a popular choice for commercial buildings due to its versatility and ease of installation. The 7.2 panel provides excellent spanning capabilities, making it ideal for wide roof spaces. Lastly, the AG panel is designed to withstand harsh weather conditions, making it perfect for agricultural and industrial roofing projects.

Whether you need a sturdy and durable panel or something lightweight and versatile, there is a fiberglass corrugated panel that will meet your specific roofing requirements.

As you can see in the image above, fiberglass corrugated panels offer not only a practical roofing solution but also a visually appealing option for various architectural styles.

Benefits of Fiberglass Roofing Panels

Fiberglass roof panels offer a range of benefits that make them a popular choice for both residential and commercial roofing projects. These panels not only provide aesthetic appeal but also contribute to better indoor lighting, improved energy efficiency, and enhanced durability.

Better Indoor Lighting

One of the significant advantages of fiberglass roof panels is their ability to allow natural light into a structure. The translucent nature of these panels enables a soft and diffused light to enter the space, reducing the need for artificial lighting during the day. This feature not only creates a brighter and more inviting environment but also helps save on energy costs by minimizing the reliance on electric lights.

Heat Absorption

Fiberglass roof panels are known for their excellent heat absorption properties. These panels effectively trap and absorb heat from the sun, making them suitable for colder climates. By regulating the temperature inside the structure, fiberglass roof panels help reduce the need for excessive heating, enhancing energy efficiency and minimizing heating expenses.


When it comes to durability, fiberglass roof panels outshine other plastic roofing options. They are made from a combination of strong polyester resin and reinforced fiberglass, which gives them exceptional strength and durability. Fiberglass panels can withstand a wide temperature range without warping, cracking, or experiencing excessive expansion and contraction. This durability ensures that the roof remains intact and resistant to damage, providing long-lasting protection for the structure.

Suitability for Corrosive Environments

Fiberglass roof panels are highly resistant to corrosion, making them an ideal choice for environments exposed to saltwater or other corrosive elements. Unlike metal or other materials that may rust or deteriorate, fiberglass panels maintain their integrity even in highly corrosive environments, such as coastal areas. This resistance to corrosion ensures that the roof remains structurally sound and retains its aesthetic appeal for years to come.

Overall, fiberglass roofing panels offer a compelling combination of benefits, including better indoor lighting, heat absorption, durability, and suitability for corrosive environments. Whether it’s for a residential or commercial project, these panels are a smart choice that can enhance the aesthetics, energy efficiency, and longevity of any structure.

Considerations for Fiberglass Roof Panels

When using fiberglass roof panels, there are a few important considerations to keep in mind. These considerations ensure the proper installation and maintenance of your fiberglass roofing system, maximizing its longevity and performance.

  1. Cannot be walked on: Fiberglass roof panels are not designed to be walked on. They are thin and lightweight, making them unable to handle excessive weight. Walking on fiberglass roof panels can cause them to break or crack, compromising their integrity. It is essential to avoid stepping or placing heavy objects on the panels to prevent damage.
  2. Must be installed over an open frame: Fiberglass panels must be installed over an open frame, rather than a wood substrate. This open frame installation allows natural light to shine through the panels, maximizing their translucency and the amount of light entering the space below. The open frame also helps with proper ventilation and reduces the risk of moisture buildup.
  3. Yellowing over time: Like any other type of plastic, fiberglass panels may experience a slight color shift and develop a yellow hue over time. This yellowing is a natural occurrence caused by exposure to UV rays. While it does not affect the panels’ performance, it is important to be aware of this color change when considering the overall aesthetics of your roof.
  4. Limited color options: Fiberglass roof panels are generally available in limited color options, typically white or clear. These color options are chosen to maximize their light transmission and reflectivity. If you have specific color requirements, it is advisable to explore alternative roofing materials that offer a broader range of color choices.

By considering these factors and taking the necessary precautions, you can ensure the successful installation and long-term performance of your fiberglass roof panels. Now, let’s move on to the next section where we will discuss the cost of fiberglass roof panels.

Fiberglass roof panels offer a cost-effective solution for your roofing needs. When it comes to the cost of fiberglass roof panels, you can expect prices to range from $2.00 to $3.00 per square foot. However, it is important to note that the actual cost may vary depending on several factors such as the size of the panels, their thickness, the specific profile, and the supplier you choose.

Factors such as size and thickness can have a significant impact on the overall cost. Larger panels or panels with greater thickness will generally cost more than smaller or thinner ones. Additionally, the profile of the panels, such as corrugated or other variations, may also affect the price.

It’s worth noting that different suppliers may offer varying prices for fiberglass roof panels. It’s always a good idea to compare prices from different suppliers to ensure you’re getting the best deal.

When considering the cost of fiberglass roof panels, it’s essential to weigh it against the many benefits these panels offer. Fiberglass roof panels provide better indoor lighting, heat absorption, durability, and resistance to corrosion, making them a wise investment for your roofing project.
