Liquid applied systems

Tremco’s range of liquid-applied roofing systems can be used as the foundation for roof podiums across new build construction projects. The systems can also restore a deteriorating but functional roof into a long-lasting, highly efficient weatherproofing system without the need for replacement. This option is cost-effective and reduces waste to landfill. Roof replacement should be seen as a last resort.


The solutions can waterproof over existing flat roof build-ups, structural concrete roof decks, industrial cladding, and can also be part of a build-up for roof replacement and new build construction projects. Our liquid applied systems offer heat and flame free application – therefore hot work permits are not required. This is essential for specific detailing and full roof estates in certain sectors.

AlphaGuard BIO

Also independently certified for use with blue roof applications.
