The position
Replacement is not the default. It is one possible outcome after the roof, cladding, gutters and interfaces have been properly assessed.
Work in context
Genuine application imagery, clearly separated from any project facts that have not been independently verified.
Explore project imageryCommercial services
A commercial building rarely fails in neat trade packages. The service range is structured around connected roof-and-envelope problems.
Cleaning, preparation, local sheet repairs, corrosion treatment, protective coating and colour change.
Liquid and spray-applied overlay routes for suitable existing commercial roof substrates and complex details.
Condition-led repair, sealing and encapsulation routes for asbestos-cement roofs and cladding.
Leak diagnosis, joint repair, corrosion treatment and seamless lining for commercial gutter systems.
Fixings, laps, cut edges, local sheet defects and compatible whole-roof protective systems.
Start with the symptom
You do not need to diagnose it. Choose the closest visible problem and follow the investigation route.
Find the route through roofs, gutters, flashings, rooflights and cladding interfaces.
02Treat cut-edge corrosion before loss of section closes the refurbishment window.
03Separate cosmetic weathering from coating failure, corrosion and failed seals.
04Step back from repeated spot repairs and establish the wider defect pattern.
05Assess repair, encapsulation, overcladding and removal against actual condition.
06Test joints, outlets, falls and adjacent interfaces before specifying a lining.
Evidence before specification
Photographs, site postcode, roof or cladding type and what the building is doing.
Defects, substrates, interfaces, drainage, access and operational constraints.
Repair, refurbishment, overlay and replacement tested against the findings.
Preparation, detailing, system build-up and delivery route defined.
