Warehousing

Warehouse cladding refurbishment for large-span storage and distribution buildings where retaining sound profiled steel can reduce disruption and avoid unnecessary replacement.

Sector Overview

Warehouse buildings present a refurbishment case that is primarily economic. A 10,000 sq m single-skin steel warehouse does not have a feasible full replacement option in most cases — the cost, programme disruption, and operational impact make it unworkable. Spray-applied refurbishment is not just preferable; for most warehouse owners it is the only practical maintenance route available. This shapes how refurbishment decisions are made in this sector: they are asset management decisions with defined payback horizons, not reactive maintenance responses. Cut edge corrosion is the primary structural concern on older profiled steel warehouse buildings — it is widespread, progressive, and underdiagnosed because it develops at roof level where it is not visible from the ground.

Common Failures in Warehousing

Large warehouse buildings typically experience cut edge corrosion as the primary structural concern, combined with UV-driven fading on south and west elevations. Access constraints often delay detection until corrosion is advanced.

Typical Roof & Cladding Systems

Single-skin profiled steel cladding (0.7mm CR4), often with polyester factory coatings from the 1980s-2000s. Roof sheets typically trapezoidal profile, wall sheets micro-rib or similar. Fixings are self-drilling steel with EPDM washers.

Typical Maintenance Challenges

Internal racking prevents ground-level inspection of roof soffits. Loading bay operations restrict access positioning. Refrigeration plant creates cold spots and condensation risks. Large uninterrupted elevations require careful weather window planning.

Typical Refurbishment Approaches

MEWP-based access for buildings under 8m eaves. Cut edge treatment precedes full over-coat. Large-area economics favour spray-applied systems. Programme planned around weather windows and operational constraints.

Survey Findings Typically Observed

Typical Outcomes From Survey

The range of outcomes a surveyor might recommend — refurbishment is not always the conclusion.

Monitoring

Surface degradation only, no ingress, no structural concern

Repair

Localised defects — rooflight details, gutter joints, impact damage

Refurbishment

Widespread coating failure, cut edge corrosion within treatable limits, substrate sound

Replacement review

Corrosion coverage exceeding 50%, sheet perforation, structural compromise

Systems Typically Specified

System selection follows survey findings. These are the systems most commonly specified on warehousing buildings — and the reason each is selected.

What Should You Do Next?

A professional site assessment establishes whether refurbishment is appropriate for your warehousing building, which system is suitable, and what the likely cost parameters are. Forti Nova's technical team reviews every assessment before recommending an approved applicator.
