Roof Waterproofing Systems
Complete roof assemblies covering membrane, insulation and accessories.
System overview
The roof is the building element most directly exposed to climate. PORMA roof waterproofing systems are built around single-ply polymeric membranes, combined with insulation, fasteners and detailing accessories to form a specifiable, installable and maintainable assembly. Systems suit both new build and refurbishment, with mechanically fastened, fully adhered or ballasted options selected according to structure, climate and service requirements.
Main advantages
Single-source system
Membrane, insulation and accessories supplied together for clear interface responsibility.
Multiple attachment methods
Mechanically fastened, fully adhered or ballasted to suit the structure.
Verifiable seams
Hot-air welded seams can be inspected on site.
Maintainable
Local damage can be repaired on site without full replacement.
Applications
- Industrial and warehouse roofs
- Commercial and retail buildings
- Public buildings and venues
- Refurbishment of existing roofs
