The Local and Regional Flat Roof Specialists


In our role as a flat roofer, we’ve grown to acknowledge that GRP roofing is the best possible alternative to traditional felt surfaces and hot application systems. Fibreglass is lightweight, hardwearing and attractive. In addition to its suitability for flat roof installation and repair work in the Shoreham and Worthing areas, GRP roofing also works well for roof terraces. This is because it has the strength and the capacity to withstand high volumes of foot traffic.


This durable material is a fairly recent addition to mainstream roofing and, combined with trim and set with a suitable resin, GRP makes an ideal surface on any flat roof for homeowners and commercial clients alike. GRP roofing has a 15-year guarantee and our company has £1m worth of public liability insurance to provide customers and clients with total peace of mind.


Today, flat roof specialists use GRP roofing in greater numbers but very few have the kind of experience we’ve gained over the past 15 years. We take incredible pride in being the go-to flat roofer for the Shoreham, Worthing and West Sussex areas. Call 01903 814865 or 07766 902323 if you would like us to inspect your flat roofing, or if you require a free, no-obligation quotation.
