2 Martingale Close:
solar panel re-installation, roof repair and waterproofing.

A targeted solar PV and roofing repair project in Richmond, focused on resolving historic water ingress, correcting defective fixing details, repairing waterproofing failures and reinstating the existing solar array onto a more robust integrated mounting system.

Project Overview

Repairing the roof first, then reinstating the solar system correctly.

JAY Executions was appointed to manage and deliver a solar PV repair and re-installation package following roof leaks linked to the original installation and fixing arrangement. The work involved carefully decommissioning the system, removing the existing panels and mounting infrastructure, inspecting the exposed roof build-up, completing local roof repairs and reinstating the solar array using a GSE integrated mounting approach.

The project also included roof repair and waterproofing works, water testing to the roof areas, gutter replacement and repairs, local fascia board replacement and making-good where required. Because the roof had to remain protected while works were opened up, the programme was managed in controlled phases with stop/start sequencing, scaffold protection and close weather awareness.

Scope of Work

A controlled repair package across PV, roofing and rainwater goods.

Solar PV Works

  • Safe shutdown of the existing solar PV system while works were undertaken.
  • Careful removal and cleaning of existing solar panels.
  • Removal of the defective existing mounting system.
  • Installation of a new GSE integrated mounting system and reinstatement of roofing elements.
  • Re-installation and re-commissioning of the solar panels, including PV array testing and commissioning checklist.

Roofing, Waterproofing & Rainwater Goods

  • Local opening-up of the roof to inspect the affected areas.
  • Correction of the batten arrangement and preparation for the solar installation.
  • Membrane and ventilation improvements, including additional vent tiles and membrane works at the bottom of the roof.
  • Roof leak investigation, local waterproofing repairs and water testing.
  • Replacement and repair of gutters, local fascia board replacement and making-good where required.
Challenges Solved

Resolving leaks caused by earlier installation details.

Existing roof penetrations

The main issue was water ingress linked to the original roofer and the fixing system used for the existing solar panels. Penetrations through the waterproofing membrane had to be identified, opened locally, repaired and tested without unnecessarily stripping the full roof.

Limited repair scope

The client’s brief required targeted repairs rather than a full roof replacement. JAY Executions managed the risk by opening the roof in controlled areas, correcting the roof build-up where required and sequencing works to maintain protection against weather.

Solar and roof coordination

The PV system had to be removed, protected, cleaned, re-mounted and commissioned while roofing repairs, ventilation improvements and rainwater goods works were coordinated around it.

Outcome

A repaired roof and reinstated solar array, with the original leak risks reduced.

The project allowed the existing solar PV system to be reinstated in a more robust manner while addressing local waterproofing, ventilation, gutter and fascia defects that were contributing to water ingress.
