Guaranteed Asphalt Ltd

Based in London, Guaranteed Asphalt are one of the leading roofing companies in the UK and we are also the UK's sole manufacturer/installer of mastic asphalt and rubberised hot melt. This gives us a unique edge on price and supply, both critical elements in the modern era of construction, particularly with the latest public sector contracts where the cost and programme are trimmed to the bone. Apart from mastic asphalt and hot melt systems, we are one of the UK's leading roofing contractors in built-up felt, living roofs, single-ply and liquid applied coatings.
