Roofers in Carshalton | The Emergence of EPDM Rubber and GRP Fibreglass Flat Roofing Systems

In more recent times, homeowners and businesses in Carshalton have turned to innovative flat roofing solutions in increasingly big numbers to improve the longevity of their installations. Traditional materials like hot felt and bitumen, both common in the past, are now overshadowed by modern alternatives such as EPDM rubber and GRP fibreglass, as well as torch-on felt.

This blog post explores how EPDM rubber and GRP fibreglass have emerged as a preferred choice with roofers and why they are superior to older systems.

EPDM Rubber | A Lasting Solution for Flat Roofs

EPDM (ethylene propylene diene monomer) rubber has become significantly popular with roofers in Carshalton due to its durability and flexibility. Made with synthetic rubber membranes, this system has revolutionised flat roofing work and provides a reliable alternative to traditional hot bitumen and felt. A primary reason for EPDM being favoured is its exceptional lifespan.

An EPDM roof can last up to 50 years with minimal maintenance, making it a cost-effective choice in the longer term. Resistance to UV radiation, extreme weather conditions and temperature fluctuations ensures it stays functional and doesn’t crack or deteriorate – unlike many older materials.

For residents in Carshalton, where unpredictable weather can take a toll on flat roofing structures, the resilience of EPDM proves invaluable. Additionally, a seamless installation process from our roofers minimises the risk of leaks, a common issue with older roofing systems that relied on felt and bitumen joints.

GRP Fibreglass | The Rise of a Versatile Roofing Solution

Another material that has surged in popularity is GRP (glass-reinforced plastic) fibreglass. GRP fibreglass is known for its strength, waterproofing capabilities and ease of installation, making it a popular choice for roofers in Carshalton. Like EPDM rubber, GRP offers superior longevity compared to hot felt and bitumen and will typically last for over 30 years with minimal maintenance.

GRP fibreglass stands out for its versatility and sleek finish. It creates a bonded and seamless surface to reduce the likelihood of leaks and provides a solid barrier against water penetration. This is crucial for flat roofs, which are more susceptible to pooling water than roofs built with a pitch.

Additionally, lightweight composition makes it easy to install without placing excessive strain on a building’s structure.

For residents in Carshalton who are seeking a roofing solution that offers both performance and aesthetic appeal, GRP fibreglass is an excellent option. The material is highly customisable and allows our roofers to adjust the final finish to suit your design needs – a distinct advantage over outdated systems.

The Practical Alternatives to Hot Felt and Bitumen

Traditional hot felt and bitumen systems were once common choices for flat roofing structures in Carshalton. However, their limitations have led to a shift towards more advanced systems like EPDM rubber and GRP fibreglass. One of the main drawbacks of bitumen is its susceptibility to cracking, particularly in areas where temperature changes can be drastic (such as on the coast).

Over time, exposure to heat and UV light causes bitumen to deteriorate and this leads to leaks and costly repairs. Older systems are prone to joint failures and require frequent maintenance from roofers to keep them watertight.

In contrast, EPDM rubber and GRP fibreglass offer seamless solutions which will eliminate the weak points where leaks usually occur. Their superior resistance to environmental factors, combined with longer lifespans, makes them a far better investment for homeowners and businesses in Carshalton.

While the initial cost might be higher, the limited maintenance requirements of these materials make them more cost-effective over time.
