Disadvantages of Fibreglass Roofing: A Detailed Look

Fibreglass Roofing

Fibreglass is a popular roofing material that is made from reinforced plastic that is bonded with glass fibres. It is also known as Glass Reinforced Plastic (GRP) roofing. Fibreglass roofing is a popular choice among homeowners due to its durability and aesthetic appeal. However, like all roofing materials, it has its drawbacks. In this article, we will discuss the disadvantages of fibreglass roofing.


One of the biggest disadvantages of fibreglass roofing is the cost. Fibreglass roofing is relatively expensive compared to other roofing materials. The installation process can also be costly due to the labour-intensive nature of the process. This makes it a less attractive option for homeowners who are working with a limited budget.


Although fibreglass roofing is known for its durability, it is not immune to damage. Fibreglass roofing can crack and break over time due to exposure to the elements. This can result in leaks and other issues that can be costly to repair. In addition, fibreglass roofing is not suitable for areas with extreme weather conditions, such as high winds or heavy snowfall.

Fibreglass roofing requires a highly skilled contractor to install it. This is because the installation process is complex and requires a high level of expertise. This means that homeowners cannot undertake the installation themselves. They must hire a professional roofing contractor to install the fibreglass roofing. This can be costly and time-consuming.


Fibreglass roofing requires regular maintenance to ensure its longevity. This includes cleaning the roof regularly and inspecting it for any signs of damage. Failure to do so can result in issues such as leaks and cracks, which can be costly to repair.


Over time, fibreglass roofing can become discoloured due to exposure to the elements. This can result in a yellow or brownish tinge, which can be unsightly. Although the discolouration does not affect the performance of the roof, it can impact the aesthetic appeal of the home.

Environmental Impact

Fibreglass roofing is not an environmentally friendly roofing material. This is because it is made from non-biodegradable materials that can take hundreds of years to decompose. Fibreglass roofing also requires energy-intensive manufacturing processes, which can contribute to greenhouse gas emissions.

Slippery Surface

Fibreglass roofing can be slippery when wet, which can be hazardous for people walking on the roof. This can be a safety concern, especially in areas with high rainfall or snowfall.


In conclusion, fibreglass roofing has its advantages and disadvantages. While it is durable and aesthetically appealing, it is also relatively expensive, requires professional installation, and regular maintenance. It is also not suitable for areas with extreme weather conditions and can be slippery when wet. Homeowners should carefully consider these factors before deciding to install fibreglass roofing.
