Trident Maintenance Services — Napier Road Pitched Roof Renewal

This residential roofing project encompassed ten terraced properties at 13-29 Napier Road in Southampton's SO19 postcode area, representing a significant planned maintenance programme for Trident Maintenance Services. The properties required comprehensive roof renewals to address deteriorating coverings and underlying membrane systems, with works designed to restore weatherproofing integrity across the entire terrace.

The scope involved complete strip-off and removal of existing roof tiles, membrane, and battening systems, followed by installation of new pitched roof materials including tile hanging elements. Operational constraints included maintaining tenant occupation throughout the works, with exclusion zones established around each property and coordination required with adjacent residents. The project operated under strict working hours of 08:00-16:00, Monday to Friday, with no weekend works permitted.

Technical specifications centred on Redland 49 tiles in brown colourway, installed at 75mm headlap with Premium Gold Treated Batten (50mm x 25mm) fixed using FIT-R Classic galvanised round wire nails. The build-up incorporated Permavent Graphite Breather Membrane for enhanced vapour management, complemented by 100mm loft insulation and TIL-R Universal Dry Fix Ridge systems in matching brown finish. Leadwork elements included ALM Lead Slate installations and weathering collars for service penetrations.

Delivery methodology required comprehensive scaffolding installation by approved contractors, with mandatory weekly inspections and wind speed monitoring using anemometers to ensure safe working conditions. All works above 28mph wind speeds were suspended, and materials handling utilised scaffold-mounted hoists to maintain safe access protocols. An NFRC Competent Person inspection validated the completed installations.

Asbestos surveys were conducted prior to commencement, with licensed removal contractors appointed by Trident where ACM was identified. The phased programme allowed 1-2 weeks per property depending on chimney condition, with waste removal coordinated through skip placement to minimise disruption. Project completion was certified on 30 September 2025, with final inspections confirming all snags had been addressed across both property groups.

Final sign-off documentation confirmed successful completion across all ten properties, with Trident Site Manager John Miller and Clerk of Works Pete Croxson validating the installations. The renewed roof systems provide enhanced weatherproofing performance and thermal efficiency through the upgraded insulation and modern membrane technology, supporting the long-term maintenance objectives for this Southampton residential estate.
