Avoid these traps before you buy
And save yourself the drama:
1. Buying “Chromadek” That Isn’t Chromadek
It looks right.
It’s the right colour.
But it’s not Chromadek.
We’ve seen this trick too many times…
Distributors sell low-grade painted sheets and call it “Chromadek”
Then vanish when the paint peels or rust shows
Real Chromadek has:
✔ Factory markings
✔ Z275 galvanised coating
✔ Consistent colour across the full batch
If your supplier can’t prove it’s genuine
You’re the one stuck with the comeback call
2. Using Z150 When You Need Z275
Z150 = budget
Z275 = long life
Most buyers don’t know the difference
And some suppliers won’t explain it
Z150 works short-term
But in Gauteng’s heat, storms, and dust
That roof won’t make it to year 5 without signs of failure
We’ve helped too many clients rip out new roofs
Only to redo them with Z275 a few months later
3. Accepting “Standard” Flashings That Don’t Actually Fit
Flashings are quiet killers
Wrong angle?
Short by 20mm?
Bend doesn’t align with your pitch?
Your water runs straight into the roof
We cut every flashing to spec
Every gutter bend
Every downpipe fit
So it seals right the first time
4. Trusting a Lead Time That Isn’t in Writing
It sounds familiar…
“We’ve got stock”
“We’ll call you back”
“It’s going out tomorrow”
Then nothing
We’ve had builders lose full days waiting
Site deadlines missed
Crews sitting idle
All because the supplier over-promised
At Roofsheeting Warehouse
If we say it’s going out
It’s already loaded or cut
And we’ll show you the manifest
5. Thinking Cheaper Always Saves You Money
Some roofing costs less upfront
But costs twice as much by month six
Replacements
Leak repairs
Client disputes
Delayed COC inspections
You don’t need the most expensive sheet
You just need the right one for the job
And someone who can help you figure that out — honestly
