Dryseal Flat Roofing

Hambleside Danelaw’s Dryseal is a single ply roofing system, suitable for low pitched and flat roofing, comprising of pre-cured GRP components.  It is far more versatile and durable than many commonly used ‘wet lay’ systems.

Manufactured from glass reinforced polyester (GRP), Dryseal, our flat roofing system, can be installed over the existing roof covering as long as the deck is in good condition and can easily accommodate the introduction of insulation as part of a warm roof.  Unlike some other single ply roofing systems, Dryseal GRP benefits from being based on standard components that provide a system guaranteed to remain leak-free for 20 years.  The leak-free Materials Guarantee is supplemented by our Approved Installer’s Guarantee direct to the customer and further covered by an insurance backed warranty. Dryseal is manufactured in accordance with ISO 9001 Quality and ISO 14001 Environmental standards and is additionally approved by the British Board of Agrément (BBA).

The system is mechanically fixed, jointed using resin and fibreglass reinforcement then finished with a UV protective top coat. Dryseal requires much less ‘wet’ working, compared to other systems on the market, in turn improving the speed and security of installation, restricting the effects of inclement weather during installation, and helping to complete an effective single ply membrane roof covering.

Dryseal can easily accommodate most complex roof detailing and can be used on flat and low pitched roofs, on garages, extensions, or to replicate lead sheet on heritage buildings.

The video above of Chelsea Heights, Sheffield was shot by Mark Dickens of P D Contract Services, a long-standing Dryseal contractor who also carries out slating, tiling and zinc roofing.

The project has been on-going since 2020 with overall roofing completion anticipated in mid-2022 exhibiting a high standard of work throughout.

Robust and non-toxic, Dryseal flat roofing system is the ideal waterproofing membrane for green roofs.  It can also be fitted under timber decking or slabs to waterproof balconies or terraces.
