Principle contractor & re-roofing

Principal contractor services for commercial and industrial projects

We act as Principal Contractor for complex commercial and industrial construction projects, providing end-to-end planning, coordination, and delivery across multiple workstreams.

Our role allows clients to remain focused on their operations while we take full responsibility for safety, quality, programme, and delivery across the construction phase.

With experience delivering multi-million-pound schemes, we integrate roofing, solar, battery storage, construction, and specialist services under a single, accountable framework. This approach reduces risk, improves efficiency, and ensures works are delivered safely, compliantly, and to a high standard.

What it means to appoint a principal contractor

As Principal Contractor, Harvest Green Developments assumes responsibility for managing the construction phase, including health and safety compliance, subcontractor coordination, site logistics, quality control, and programme management.

 

We ensure all works are planned correctly, sequenced efficiently, and delivered in line with statutory requirements, with clear communication maintained throughout the project.

Clients benefit from a single point of contact, a single programme, and a coordinated delivery strategy, rather than managing multiple contractors independently.

Integrated project delivery you can rely on

As Principal Contractor, we manage multi-discipline projects that commonly include:

Solar PV installations

Battery storage systems

Full re-roofing solutions

Re-cladding works

HVAC decommissioning and reinstatement

Installation of safety systems

Lightning protection systems

Scaffolding design and management

Internal and external decorating

Security doors and windows

Asbestos removal and remediation

New roof systems and guttering

Re-roofing solutions and retrofit solar

Re-roofing and solar delivered together

One of the most common applications of our Principal Contractor service is re-roofing combined with solar installation. For many commercial buildings, ageing roof structures present both a risk and an opportunity.

By managing both scopes together, we protect the building while enabling long-term energy generation.

A smarter approach to re-roofing

Delivering re-roofing and solar as a single project ensures:

Roof structures are designed to support solar from day one

Scaffolding and access systems are installed once

Operational disruption is reduced

Programme times are shortened

Overall project costs are improved

As Principal Contractor, we manage the full re-roofing scope, including asbestos removal where required, new roof systems, guttering, and safety works, with solar integrated seamlessly within the same programme.
