Q: What is GRP material?

A: Glass-Reinforced Plastic is a composite material made, as the name suggests, of plastic re-inforced with fine glass fibres. It is lightweight and incredibly tough. In fact, it is so tough that it is used on the hulls of boats, such as RNLI life boats.

Q: What colours can I have my flat roof?

A: There are 8 different colours available for an Everest flat roof, and 3 different finishes. 

Q: Why choose an Everest flat roof?

A: They are cost effective and, if built correctly, incredibly robust. At Everest, we are so assured of the quality of our flat roofs that we offer a lifetime guarantee against water ingress. Everest Rooftrim range are included as part of the installation and these products also have extensive guarantees, with our white uPVC fascia guarantee for a lifetime against discolouration.

Q: How long will a GRP roof last?

A: GRP will last for 30–50 years and more with no measurable deterioration.

Q: How do I clean a GRP flat roof?

A: As we don’t want homeowners climbing on top of their flat roofs, we have done everything we can to ensure they are virtually maintenance free. GRP is 100% waterproof and very durable. There is no need to replace or repair. Also, the roofs are designed to take water away from its surface, reducing pooling. For more information on caring for your flat roof, click here.

Q: Will Everest repair a damaged flat roof?

A: It is our policy only to repair our own products, so if you wish to repair a roof installed from another company, we can only do so if you want us to remove it and install our own product. 

Q: Can I customise the look of my flat roof?

A: Whether you want your flat roofs to blend in to the existing style of your home or make a statement, we have provided a range of 8 stylish colours, including caramel, fern, granite and platinum, as well as three different finishes; standard, décor-style slate chippings and non-slip.

Q: How can you be sure the material will never rip or tear?

A: GRP is a material more commonly used in boat building and for expedition shelters in the Antarctic, where extreme conditions and temperatures can really take their toll. If it can last there, it can last anywhere, and that’s why we offer a lifetime guarantee.
