There comes a point where no amount of patching or coating will save a roof or wall — the sheeting itself has simply reached the end of its life. When that happens, the answer isn't another repair, it's a clean re-skin. New sheeting and cladding gives an ageing industrial or commercial building a weathertight, modern envelope built to last decades — and Sicon Group installs it end to end, from strip-out to the final flashing.

When It's Time to Re-Sheet

Restoration and coatings do a superb job while the underlying sheeting is still sound. But once sheeting has corroded through, buckled, or lost its structural integrity, coating over it only hides the problem. New sheeting is the reset — it removes the failed skin entirely and replaces it with a fresh, fully weatherproof one. The tell-tale signs it's time:

  • Corrosion that has perforated the sheets, not just marked the surface
  • Sheeting that flexes, lifts or rattles because the fixings no longer hold
  • Repeated leaks spread across the whole roof rather than at one or two points
  • Old asbestos or fibre-cement sheeting that should be removed and replaced
  • A building being repurposed or rebranded that needs a modern, uniform look

Roof Sheeting and Side Cladding — the Full Envelope

The two go hand in hand. Roof sheeting is the weatherproof skin over the top of the building; cladding is the same profiled metal used vertically on the walls. Replacing one without the other usually leaves a mismatch — in colour, condition and weather performance. We handle both together, so the finished building reads as one clean, sealed envelope from ridge to ground.

Choosing the Right Profile and Material

There's no single "best" sheet — the right choice depends on the building. We specify to suit it:

  • Profile — IBR, corrugated and box-rib profiles each suit different pitches, spans and looks
  • Material — galvanised or colour-coated steel, matched to the site's exposure and the finish you want
  • Pitch & span — low-pitch roofs and wide spans carry specific drainage and fixing requirements
  • Exposure — coastal salt air, industrial fumes or intense Highveld UV call for tougher coatings and detailing
  • Insulation — new sheeting is the ideal moment to add or upgrade roof insulation underneath

How a Re-Sheeting Project Runs

Stage 01

Assessment & Specification

We measure the roof, inspect the structure beneath, and specify the profile, material and fixings suited to your building and its climate — in writing, before any work begins.

Stage 02

Safe Strip-Out

The old sheeting is removed — and where asbestos is present, it's stripped and disposed of under the correct legal procedures — exposing the purlins beneath.

Stage 03

Structure & Purlin Checks

Purlins and fixing points are inspected and repaired so the new sheeting lands on sound, load-bearing steel rather than tired supports.

Stage 04

New Sheeting & Cladding

The new sheets go on with the correct fixings, laps and sealing, and the walls are clad to match — one uniform, weathertight envelope.

Stage 05

Flashings, Ridges & Sign-Off

Ridge caps, flashings and every weatherproofing detail are fitted, then the roof is inspected and handed over with a workmanship guarantee.

Why Re-Sheet with Sicon

A re-sheeting project is only ever as good as the crew and the detailing. With Sicon Group you get:

  • A specification matched to your building, pitch and climate — not a one-size sheet
  • Certified, insured teams working to strict height-safety standards
  • Old asbestos removed and disposed of correctly where it's present
  • Insulation and waterproofing addressed while the roof is open
  • A workmanship guarantee and full sign-off on completion
Worth Knowing

"Re-sheeting isn't only about weatherproofing — it's the one moment the roof is fully open. Adding insulation, upgrading drainage and sealing every detail now costs a fraction of doing it later. Done once and done right, it sets the building up for the next twenty years."
