When it comes to factories and warehouses, the roof is your first line of defense against the elements. At Unitech SA, we understand how crucial proper sheeting installation is for protecting your assets, machinery, and operations. Unfortunately, we’ve seen the damage that incorrect installation can cause—and it’s not just a small leak here and there. It can mean thousands in repairs, operational downtime, and even structural risk.
Let’s take a closer look at the dangers of poor sheeting installation—and how we at Unitech SA can help you avoid them.
What Can Go Wrong?
Incorrect sheeting installation is more common than you’d think—and the consequences are serious:
1. Water Damage
If sheeting isn’t properly sealed or overlapped, rainwater finds its way into your building. This can damage insulation, electrical systems, stock, and machinery.
2. Persistent Leaks & Damp
Leaks might seem minor at first, but over time they can lead to mold, mildew, rust, and structural decay. It’s a slow, silent threat—and by the time you notice it, the damage is done.
3. Compromised Structural Integrity
Incorrect sheeting puts stress on your roof structure. Fasteners that aren’t properly secured or metal sheets that lift in the wind can result in real structural risks.
4. Reduced Roof Lifespan
Poor installation leads to faster wear and tear. What should last 20+ years might only last 10, and early replacement is never budget-friendly.
5. High Maintenance Costs
More repairs, more inspections, more worry. And unfortunately, these costs add up over time—especially if you’re constantly chasing after quick fixes.
Where It Usually Goes Wrong
From our experience working on industrial roofs, here are some of the most common installation mistakes we come across:
-
Inadequate Fastening: Sheets lift or warp because they weren’t properly secured.
-
Incorrect Overlaps: Water seeps in through gaps that should’ve been covered.
-
Bad Flashing Work: Vents, skylights, and ridges weren’t sealed properly.
-
Poor Sealing: Missing sealant or foam closures lead to water ingress and air leaks.
Each of these might seem small, but together, they can turn into big problems.
