Built-Up Felt Roofing

Southern Projects has completed over 100 flat roofing installations, specialising in built-up felt systems that deliver reliable waterproofing performance for commercial and industrial properties. Our experienced roofers focus on torch-applied and self-adhesive felt systems, complemented by liquid coatings and single-ply membrane solutions where appropriate.

Our built-up felt roofing approach combines proven materials with systematic installation processes, ensuring each project meets the specific requirements of the building envelope whilst maintaining compliance with current building standards.

We deploy two primary built-up felt techniques:

• Torch-applied systems using heat-bonded membranes for superior adhesion
• Self-adhesive felt applications for sensitive environments or restricted access situations
• Liquid coating integration for complex details and transitions
• Single-ply membrane solutions where building design requires alternative approaches

Built-up felt systems provide comprehensive waterproofing through multiple membrane layers, creating redundant protection against weather ingress. The systems we install offer enhanced thermal and UV performance compared to traditional alternatives.

• Proven multi-layer protection against water penetration
• System versatility to accommodate various roof profiles and details
• Enhanced thermal performance contributing to improved building U-values
• Superior UV resistance extending system lifespan
• Compatibility with existing roof structures and drainage systems

• Faster installation schedules reducing building disruption
• Low-disruption methods maintaining operational continuity
• Systematic approach ensuring consistent quality across the roof area
• Adaptable techniques suitable for refurbishment and new-build applications

Built-up felt roofing systems deliver significant whole-life cost advantages through extended service life and simplified maintenance requirements. The multi-layer construction enables early detection of potential issues before they compromise the building envelope.

• Lower whole-life costs through extended system durability
• Reduced maintenance requirements compared to alternative flat roofing systems
• Early issue detection preventing costly water damage
• System repairability extending overall roof lifespan

Our installations maintain full compliance with building regulations and industry standards. Each project includes comprehensive documentation ensuring traceability of materials and installation methods.

• Guaranteed systems backed by experienced installation teams
• Full compliance documentation for building control and warranty purposes
• Systematic quality checks throughout the installation process
• Traceability of materials and installation methods for future reference
