GRP Roofing isn’t just for new builds – you can replace your existing felt, rubber, or membrane roofing with glassfibre for better waterproofing and lower maintenance requirements.

Pay Attention to the Lifespan of Your Roof

Most felt roofs come with a 10-year guarantee, which sounds like a long time but over 60 years it will need to be changed 6 times. Proplas’ 25 year guarantee on our GRP roofs means that you would only need to replace the roof twice if you wanted it to be consistently covered by a guarantee. In truth, a GRP roof would probably last the full 60 years with no faults or maintenance requirements. GRP has been used for over 60 years in commercial and domestic applications such as boat building, so we know that the material can stand the test of time and exposure to the elements.

Longevity has an Impact on Cost

While a torch-on felt roof is typically cheaper than a GRP roof, it is a short-term saving considering how often the roof will need to be repaired or replaced. Felt and rubber roofs require maintenance and repairs on a frequent basis to prevent leaks and even plants from growing on the roof.

GRP roofs are the most damage resistant material that you can choose for your roof, and therefore have the lowest ongoing maintenance and repair costs. With a quality installation, you will not need to replace your flat roof again within your lifetime.

Replacement Considerations

All Proplas quotes are based on all 3 layers of the GRP roof. We can build on your existing roof boards, but this depends on the quality and condition of the boards – if you have had a leak, we may need to replace the boards to ensure that the roof can be installed properly.
