SMCC pharma unit: a leak-free roof across complex slope transitions
The SMCC pharmaceutical manufacturing unit needed a roof that would not leak at all, in line with stringent pharmaceutical compliance standards, and its shed design had complex slope transitions.
We developed custom roofing profiles and closures shaped for each transition, and checked water flow, overlaps and sealing in a 3D review before production. The consultant approved it at the first review, and the roof stayed dry through the monsoon.

The challenge
The SMCC unit makes pharmaceuticals, and its stringent compliance standards left zero tolerance for roof leakage.
The shed design had complex slope transitions, and every change of slope significantly increased the risk of water ingress, most of all during the monsoon.
What was at risk
- Water ingress in the monsoon
- Leaks at the slope transitions
- Pharma compliance
How we handled it
MNF Metals treated the requirement as an engineering challenge rather than a standard supply order, and worked out every transition point before production started.
- Custom roofing profilesWe developed roofing profiles specifically for this shed and its slopes.
- Closures for every transitionSlope-optimised closures were made for each transition point, so the roof was sealed where water was most likely to get in.
- 3D review before productionA detailed 3D technical review validated the water flow, the overlaps and the sealing integrity before production started.
The result
- Approved at the first reviewThe consultant approved the roof in the first review cycle.
- Precise at every junctionThe roof went on accurately across the complex slope junctions.
- Zero leakageThe roof stayed dry, even after the monsoon.
- Pharma-grade qualityThe roofing met the quality a pharmaceutical facility expects.
Why clients choose MNF
Some buildings cannot take a leak at all. In pharmaceutical manufacturing and other sensitive environments, performance, hygiene and long-term reliability are non-negotiable. This job shows how our engineering-driven approach takes the risk out of a roof before production starts.
