If you're seeking a durable, attractive and flexible roofing solution, then Dryseal is a great choice. Manufactured from long established glass reinforce polyester (GRP), Dryseal can be installed over an existing roof covering as long as the roof deck is in good condition, easily accommodating the introduction of insulation to form a warm roof. The Dryseal flat roofing system is guaranteed to remain leak free for 20 years and comes with an insurance backed warranty. The Materials Guarantee is supplemented by our Approved Installer's Guarantee directly to the customer.
Dryseal is suitable for the 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. As it is robust and non toxic, Dryseal is the ideal water proofing system for green roofs, and can be fitted under timber decking or slabs to waterproof balconies or terraces.
