Roofing Across Sussex
Our teams work across northern Sussex, including Crawley, Horsham, East Grinstead and the towns along the A23 and M23, and travel further south into the county for planned and contract work. The Gatwick area in particular has a dense commercial and industrial base that suits our large roof and planned maintenance work.
In East Sussex, we carried out a large flat roof refurbishment at Flagship School in Hastings, a specialist SEN school. The existing roof was ageing but structurally sound, so we installed a Restec Flexitec 2020 GRP overlay rather than a full replacement, saving cost and disruption while the school kept running. The school’s site manager told us the overlay system saved them time, money and unnecessary environmental impact.
Close to the West Sussex border, we also completed a Bauder flat roof replacement in Lingfield, a few miles from East Grinstead, and a flat roof refurbishment at Warlingham Park School. View our full project portfolio.
Many Sussex schools and commercial buildings have flat roofs that are ageing but still sound underneath. In those cases an overlay system can extend the life of the roof for far less than a full strip, which is why we always survey first and recommend the least disruptive option that will last.

Sussex Roofing FAQs
Which areas of Sussex do you cover?
We cover northern Sussex strongly, including Crawley, Horsham, East Grinstead and the Gatwick area, and reach further into the county for planned and contract work, such as our school project in Hastings. Call us to confirm coverage for your site.
Do you carry out commercial roofing near Gatwick and Crawley?
Yes. The Crawley and Gatwick area has a strong commercial and industrial base, and large span flat roofing and planned maintenance there are a natural fit for our teams.
Do you work on Sussex schools and social housing?
Yes. We refurbished the flat roof of Flagship School, a specialist SEN school in Hastings, and we deliver school roofing with Enhanced DBS checked teams and holiday programmes, plus planned and responsive works on housing association and council homes across the county.
What is a roof overlay, and when is it suitable?
An overlay is a new waterproofing system installed over an existing flat roof that is ageing but structurally sound, so there is no need to strip it off. It is quicker, cheaper and less disruptive than a full replacement, which is why we used a GRP overlay at Flagship School in Hastings. We confirm whether an overlay is suitable with a survey first.
