Buyer's guide
Liquid Roofing vs GRP
Liquid systems shine where GRP can't — over awkward upstands, around penetrations, on complex green-roof or balcony detail. GRP shines on regular rectangular decks. Often we specify a combination — GRP main, liquid detail.
- Liquid: ideal for complex detail and overcoats
- GRP: ideal for rectangular new decks
- Liquid can be applied over existing membranes
- GRP needs a sound deck strip-down
- Both warranted 20–25 years
How we'd specify on your project
Every comparison depends on the existing structure, the surrounding properties, and how long you'll hold the building. We'll tell you on the survey, in writing, which we'd specify and why.
