What You Need to Know About GRP Fibreglass Roofing Systems

Glass Reinforced Polyester, also known as GRP fiberglass roofing, is mixed material and reinforced with first-class glass fibers. It is designed especially for flat roofing system applications and one of the most popular roofing types in the market. You can use it for domestic properties, from housing up to huge industrial buildings.

Fiberglass roofing can be placed quickly and cover huge areas such as industrial complexes and warehouses. Many of the flat roofs you can see in commercial areas contain fiberglass.

The simplicity and safe installation of GRP roofing and the finished product are known as having a longer lifespan than the felt roof.

GRP roofs start with applying a resin catalyzed layer for the coating to have the best quality, then wait until the roof deck is completely dry (ideal to Oriented Standard Board or OSB3 and G3 board wood roof deck). Then a sheet of fiberglass matting is placed on the top and followed by a second coating layer of resin catalyzed to complete the system. 

Advantages of Having GRP Roofing

• Convenience: When we talk about the selection of roofing materials, nothing gets more convenient than fiberglass. The smooth nature of its form means no wastage, more environmentally friendly, less pressure on surroundings, and the best replacement to felt which is not often recycled. From the manufacturing site, the material can be pre-cut. Notably, the transport is fast, and the installation process is straightforward.

• Maintenance Ease: The maintenance process of this type of roofing is relatively easy and straightforward by the workers or engineers. The truly innovative design of fiberglass as a chemical substance is smooth, which significantly reduces the probability of environmental erosion and water destruction.

• Longevity and Durability: The durability of fiber roofing matches its versatility, and from here, we can find one of the main differentiators between fiberglass and felt. Typically fiberglass will last twice over the felt lifespan. A felt roof typically offers a short lifespan of only 6 to 8 years. In the majority of cases, fiber roofing can last up to 20 years, representing an essential and significant investment for your business premises, office, or your home. In installing a roof hatch in your fiberglass roofing on your property, you will have complete peace of mind regarding its longevity.

• Safety: When you choose fiberglass roofing, you have the confidence to work or live because your roofing material contains laminated resins that are fire-retardant and corrosion-resistant. Safety is the main priority in every premise, so choosing fiberglass roofing systems is essential.

Fiber Roofing Installation

• Preparation: The first step in GRP roofing installation is to prepare the decking. It means to remove all the unwanted materials or substances of the deck, making sure that the joists are clear and clean from lots in preparation to install fiberglass. The appropriate boards go to their application areas, ensuring the deck is free of moisture and completely dry to ensure a proper installation of fiberglass roofing.

• Roof Lamination: This process applies a correct proportion of resin mixtures and mat and board to cover all corners. It is essential to have a proper ratio of resin to glass. Nevertheless, the recommended ratio is two-thirds glass and one-third resins to the mat and board, respectively, giving a resin-coated deck and transparent laminate finished.

• Final Application: Allow to dry the laminate and cure, and then you can add the catalyst mixture to its required amount, apply it thinly to avoid crack. You can find the catalyst ratio in the container of your roof supplies kits.
