Do you want to find out: How long will a GRP roof last? This article explores the life expectancy of GRP roofing and what effects its need for replacement. Flat Roofers Basingstoke provide GRP fibreglass roofing replacement for Andover, Basingstoke, Winchester and the surrounding areas.

How Long Do Fibreglass Roofs Last?

In general, most fibreglass roofs come with a standard guarantee of 25 years. However, with diligent care, regular cleaning, and proper maintenance, these roofs can far exceed this timeframe, becoming a long-term investment that stands the test of time.

Despite the higher material costs compared to alternatives like rubber, fibreglass proves an enticing choice due to its exceptional resistance to damage. Repairs to fibreglass roofs are seamless and almost unnoticeable, ensuring a flawless and enduring surface.

While fibreglass may be less flexible than rubber, it compensates with remarkable resilience and weather resistance. Weatherproof and resistant to leaks or frost damage, fibreglass roofs provide dependable protection against various environmental challenges.

Traditional roofing materials, such as asphalt or mineral felt, generally have a limited life expectancy of 10 to 15 years and are more susceptible to leaks and water damage through pooling.

On the other hand, fibreglass flat roofs, if well-maintained, can last between 20 to 30 years before requiring replacement. Furthermore, advancements in materials, such as plastic and rubber, have further extended the potential lifespan of fibreglass roofs, offering even more enduring and cost-effective solutions.

What are the options for flat roof materials?

When it comes to selecting the ideal material for a flat roof, several options are available, each offering its unique characteristics and benefits. Understanding the properties of these materials is essential for making an informed decision regarding the best choice for your roofing needs. Let's explore the four primary options commonly used for flat roofing:

Felt Roofing

Felt roofs are constructed using a three-layer system, consisting of a vapour control layer, a reinforced felt layer, and a cap sheet. The combination of these layers is carefully welded together, earning this material the popular name, 'Torch-on felt.'

Due to the expertise required and the use of a hot flame during installation, it is strongly advisable to have a professional contractor handle the fitting process. Felt roofs generally come with guarantees ranging from 10 to 20 years, depending on the product's quality and the manufacturer's specifications. However, with proper maintenance and care, felt roofs can often endure beyond their guaranteed lifespan.

Despite being the more budget-friendly option, felt roofing may not be the most visually appealing choice for those seeking an aesthetically pleasing roof. It is often selected for concealed or unused areas, as visible patches may remain after repair work. Additionally, felt roofs are susceptible to damage from foot traffic during hot weather or from window cleaners placing ladders on them in warm conditions.

EPDM Rubber Roofing

EPDM rubber roofs have gained popularity for their impressive durability and waterproofing capabilities. Unlike felt roofing, EPDM can often be installed in one continuous layer without the need for joins, provided the roofing area is of an appropriate size.

EDPM boasts exceptional elasticity and toughness, enabling it to withstand foot traffic and accommodate temperature fluctuations without sustaining significant damage. Due to these qualities, well-installed EPDM roofs can often come with guarantees ranging from 30 years upwards, making them a long-lasting and reliable option for flat roofing.

However, it is crucial to ensure proper installation to achieve the best results, especially around complicated corners and pipes. A well-executed installation ensures a pleasing and seamless finish. While repair work on EPDM roofs is feasible, the patched areas may remain visible, which is something to consider when opting for this material.

TPO Rubber Roofing

TPO rubber roofing, or thermoplastic polyolefin roofing, has gained popularity due to its superior environmental credentials and user-friendly heat-welding process compared to EPDM.

This material comprises thermoplastic polyolefin elastomers and thermoplastic polyolefin, creating a two-component elastomer system. TPO roofing typically has an estimated lifespan of around 20 years, offering reliable performance for an extended period.

TPO rubber roofs have become a favoured choice for environmentally conscious individuals, as their production and usage demonstrate a commitment to sustainable practices.

The material's ability to be heat-welded easily streamlines the installation process, ensuring a secure and watertight roofing system. For those seeking an eco-friendly and durable roofing option, TPO rubber roofing is worth considering.

Fibreglass Roofing (GRP)

Fibreglass GRP roofs, also known as glass-reinforced plastic roofs, are another option for flat roofing solutions. These roofs are typically laid in one or two layers, resulting in a joint-less and sleek finish. The versatility of fibreglass allows it to be customised in various colours, offering aesthetic appeal alongside its practical benefits.

Most fibreglass roofs come with guarantees of 25 years, though their lifespan can significantly exceed this duration if well-maintained and cared for.

Although fibreglass roofing may be the most expensive option due to material costs, it offers exceptional resistance to damage, making it an attractive long-term investment.

Repair work on fibreglass roofs is straightforward, with the patched areas blending seamlessly into the existing surface, leaving little to no visible traces. Its weatherproof nature and resistance to leaks and frost damage make it a reliable and durable choice.

The durability and strength of fibreglass are evident in its use in other industries, such as boat hulls, where its robustness is tested in harsh marine environments. Additionally, fibreglass offers an excellent strength-to-weight ratio, making it a preferred choice for various applications.

How Much Does a Fibreglass Roof Cost?

The cost of a GRP (glass-reinforced plastic) roofing system varies depending on factors like new construction or repair/alteration of an existing roof. Repairs or alterations are generally more cost-effective. The roof's surface area and professional installation also impact the budget. Structural repairs and adjustments to guttering or downpipes should also be considered.

Despite GRP being more expensive than traditional felt or EPDM rubber roofing, its exceptional durability, low maintenance, weather resistance, and attractive finish make it a highly worthwhile investment.

The average cost for a GRP roof is around £70 to £90 per square metre, which may vary by location and specific project requirements. While DIY installation may seem cheaper initially, hiring experienced professionals ensures a proper warranty and the best results for your GRP roof, ensuring peace of mind and long-term cost savings.
