Why is GRP the Best Flat Roof Material?

Glass Reinforced Plastic or fibreglass roofing is made from polyester resin which is toughened and strengthened by chopped glass fibres to form a GRP laminate. Initially, it was used on water containers and boats, but for some time, it has been widely used in the construction industry. It is not only strong and durable but also surprisingly light; therefore, it is popular among many industrialists. The fibres within this are very small and fine. They do not provide enough structural support and waterproofing, but when mixed with a hardened resin-like polyester, the aftermath is strong and flexible.

If installed effectively and reasonably taken care of, it can last for 30 or more years.


Multiple Reasons Why You Should Choose a Grp Roof for Your Property


String and Durable: Though lightweight, GRP is a solid material. In some cases, it is proved to be much stronger than metal, making it a perfect structural support system, especially if you frequently have gutter maintenance and window cleaners on your flat roof. Moreover, if correctly maintained, it can stand any damage or pressure while remaining in good condition.

Versatile and Adaptable: GRP can be moulded into almost any design and shape.

Cheap and Effective Protection: Fiberglass is an excellent waterproofing material for your roof- providing high performance at a low cost. And because it is built to last for years, it will save you a lot of money, so you will not have to change it any time soon.

Maintenance-free: Another huge advantage is that it is almost maintenance-free. Given that there are no joints and no welds, there is no way whatsoever that the structure could be damaged or weekend. There is no ongoing maintenance required, no complicated components, and the guarantee of protection goes above and beyond other comparable materials.

Customisable: You can customise GRP flat roofs in any way possible. Somewhat, it is easier to design and install these roofs to duplicate and copy other materials. You can match these roofs with the décor and style of your home. In addition, they can be used to create statement pieces to complement the background of your home.

Perfect for Rooftop Gardens: GRP is a thick and dense material that is the best for rooftop gardens. But, if you throw topsoil on it, you will need to install drainage points. Anyhow, it is a good material to use.

Outlasts Cheaper Material: You might want to go with resin or a felt roof system to save a few hundred pounds, but the reality is you will pay twice for cheaper material.

Environmentally Friendly: It is safer to say that there is no risk to the environment in GRP installation as there are no harmful emissions or toxins used.

Weathers Well: The distinctive qualities of GRP mean it can withstand extreme weather conditions. Regardless of heavy rain or shine, it will remain undamaged by the atmospheric condition.

How Much Does a Fibreglass Roof Cost?


The cost of a fibreglass flat depends on various factors, including the roof size, specifications and finishes.

The general expense of any material will depend on whether a new rooftop is being built or the existing one is being repaired or fixed. And the latter will be relatively less expensive.

You will probably need to consider if auxiliary fixes or modifications are required to the downpipes and guttering.

Because of its durability and sturdiness, you can hope to pay around £70-£90 per square meter. However, this cost can vary by region or area.

Can You Repair a Fibreglass Roof?

Fibreglass roof is extremely durable, and if correctly and properly installed, it won’t need any repairs or revisit every year. However, like any roof, it can become brittle, which results in appearing various holes and cracks. In this case, you can repair the entire or a section of your GRP roof, which will be completely watertight in no time. Moreover, many fibreglass options can be costly, but if it’s small, you can save a lot of money by fixing them yourself.


Roofing Supplies Used in GRP Roofing


A GRP resin, hardener, catalyst, top coat resin, roof trims, flashing, and fibreglass mating are the essentials of a GRP roofing system.

In addition to the above, other materials include adhesives and sealants to bond flashing and trims together with brushes, rollers and buckets.

Furthermore, to enhance the look of the roof, other materials include corners and slate chippings.

How is GRP Roof Better Than Other Roofing Materials?


GRP fibreglass is the most long-lasting and substantial roofing system on the market.

It was used to build aircraft components and marine vessels in some cases.

Its remarkable strength is comparable to certain types of steel; for that reason, it is used extensively on patios, verandas and many other installations.

The final topcoat of polyester-based resin can have its colour tailored; once completed, it can be easily regenerated and cleaned with a pressure waterjet. On the contrary, roofing material is very limited in colour customisation.

In GRP, fewer materials are needed for replacement (insulation, timber, resin and other building components. This means less fuel is burned and fewer natural resources are required to install, equating to lower carbon emissions.
