Rooftop Works at Brompton Barracks - What It Takes to Lift a 59-Tonne Crane Safely

June 2, 2026

Before any roofing work begins at Brompton Barracks, CGA had to answer a straightforward question: how do you safely get people and materials onto the roof of a Grade II listed building on an active military site?

The answer, in this case, is a 59-tonne crane.

CGA has been appointed to deliver significant roof repairs and upgrades to the Officers' Mess at Brompton Barracks in Chatham. The building is listed, the site is live, and the roof requires the kind of access that does not come from a standard scaffold. Getting the crane on site required a full structural assessment of the ground conditions, a detailed method statement and a lift plan, all reviewed and approved before any equipment moved.

Works include lead and slate roof repairs, replacement of valley and parapet gutters and structural remediation where the roof structure has deteriorated. Heritage roofing on a constrained site demands careful sequencing and the right technical experience.

Brompton Barracks is an operational military establishment. That adds a layer of coordination well beyond the standard contractor-client relationship: access arrangements, security requirements and an awareness that the works must not compromise the primary function of the site.

Works are now underway.
