Project Overview:
To install a new Langley felted roof system to a block of flats after their existing roofing system failed, causing numerous leaks to the apartments in the building.
Phase 1: Scaffolding & Site Preparation:
Challenges:
- Ensuring safe access to the roof for workers and materials
- Avoiding disruption to building occupants
- Weather conditions impacting scaffolding stability
Solution:
- Designed a full perimeter scaffold system with debris netting for safety
- Used hoists and lifting equipment for material transport
- Conducted thorough risk assessments and compliance checks (CDM regulations, edge protection, fall arrest systems)
Phase 2: Roof Preparation & Removal:
Challenges:
- Stripping old roof without damaging the structure
- Managing waste disposal and minimizing dust/debris
- Avoiding water ingress during the transition period
Solution:
- Phased removal strategy to keep sections watertight
- Installed temporary waterproof sheeting after stripping each section
- Used Langley-approved waste management and disposal methods
Phase 3: Installation of Langley Felted Roof System:
Challenges:
- Ensuring proper adhesion and bonding of felt layers
- Managing temperature and weather conditions for best application results
- Compliance with Langley’s specifications for warranty eligibility
Solution:
- Applied Langley-approved primer before installing the underlay
- Installed a two-layer high-performance bituminous felt system
- Used hot air welding and mechanical fixing methods for durability
- Conducted quality control inspections at each stage
Phase 4: Final Inspection & Handover:
- Full Langley warranty compliance check
- Joint inspection with client and Langley representatives
- Provided maintenance guidelines and recommended inspection schedules
Outcome:
- Successfully installed a durable, waterproof, and energy-efficient roof
- Minimal disruption to building operations
- Achieved Langley system warranty certification
