When clients appoint a roofing contractor, they often think purely in terms of waterproofing systems. At Gable Projects, we go far beyond that. Alongside delivering high-quality flat roofing, pitched roofing, cladding and sheeting, and liquid roofing systems, we also operate as a Main Contractor or Principal Contractor, providing a fully managed, turnkey solution.
This means fewer interfaces, reduced risk, streamlined communication, and complete accountability from start to finish.
More Than Just Roofing
Our core expertise lies in delivering technically robust roofing solutions across commercial, industrial, public sector and residential projects. Whether it’s a complex flat roof replacement, a new build cladding package, or a specialist liquid waterproofing system, our team ensures every detail is handled with precision.
However, many roofing projects require additional associated works to ensure the building envelope performs as it should. That’s where our expanded capability makes a real difference.
By acting as Main Contractor, we manage and deliver not just the roofing package, but all supporting trades required to complete the project safely, compliantly and efficiently.
Our Principal Contractor Capabilities
When undertaking roofing or envelope works, Gable Projects can coordinate and deliver:
M&E (Mechanical & Electrical)
We manage and install rooftop plant supports, cable routing, containment, lighting alterations, extract systems, and electrical modifications required as part of roofing refurbishment or replacement projects.
Mastic Asphalt Car Parks
Specialist mastic asphalt waterproofing for car parks, podium decks and trafficked areas, ensuring durability, slip resistance and long-term performance.
Reactive & Emergency Maintenance
Rapid response teams available for urgent roof leaks, storm damage, structural failures and water ingress issues. We secure, repair and make safe properties with minimal disruption.
Brickwork & Structural Alterations
Parapet modifications, upstand construction, repointing, coping stone works and general masonry required to facilitate roofing upgrades.
Gutter Repairs & Rainwater Goods
Full repair or replacement of guttering systems, downpipes, outlets and drainage connections to improve water management and prevent façade damage.
Asbestos Removal
Licensed asbestos removal and encapsulation carried out in full compliance with current regulations, ensuring safe project delivery.
Steelwork
Fabrication and installation of structural steel, plant supports, edge protection supports and strengthening works associated with roofing upgrades.
Internal Repairs & Decoration
When roofing defects have caused internal damage, we carry out plastering, ceiling repairs, redecoration and associated remedial works, providing clients with a complete reinstatement solution.
Drone Surveys & Reports
High-resolution drone inspections and condition reports allow us to safely assess difficult-to-access roofs and provide accurate diagnostics before works commence.
