Karachi Chemical Services provides high-performance metal roof waterproofing services for industrial sheds, warehouses, factories, commercial buildings, and steel containers. Metal waterproofing coating, particularly for roofs, is the process of applying a protective layer to prevent water damage and extend the lifespan of the metal. This is often achieved through the use of liquid rubber, polyurethane, or silicone coatings, which create a seamless, waterproof barrier.
Why is Metal Waterproofing Important?
Metal roofs in Karachi face extreme weather conditions:
Heavy rainfall
High heat exposure
Rust formation
Metal expansion & contraction
Bolt/fastener leakage
Welding joint cracks
These issues cause water leakage, dripping, rust damage, and expensive inventory loss inside warehouses and industrial facilities. We use industrial-grade waterproofing materials — Sealant XT100, Aquashield AS100, and UV Reflector 101 — specially designed for metal
surfaces.
🟨 Why Metal Roofs Leak (Common Issues in Karachi)
Metal sheet roofs commonly face:
Screw & fastener hole leakage
Overlap joint gaps
Ridge cap leakage
Rust formation
Sheet expansion & contraction
Sealant loss due to heat
Poor drainage causing water collection
Damage from heavy rain or wind
✔ Loose bolts
✔ Hole penetration
✔ Weak welding joints
✔ Metal expansion gaps
✔ Damaged sheets
✔ Standing water
✔ Heavy rains
Our waterproofing system ensures complete sealing and long-term flexibility. We fix all of the above using advanced sealing and coating systems.

To repair a leak in a metal roof, start by identifying the leak's source. Clean the area thoroughly, removing any debris, rust, or old sealant. For small holes or cracks, a high-quality roofing sealant or caulk compatible with your roof material can be applied. For larger holes, consider patching the area with a piece of matching metal, securing it with screws and sealant. If the damage is extensive, replacing the damaged panels may be necessary. Also, inspect and potentially replace damaged flashing around penetrations like chimneys or vents.

Application of Aquashield AS100 (Liquid Rubber Elastomeric Coating) for complete waterproofing.
5. UV & Heat Protection Coat
Applying UV Reflector 101 to protect metal roof from sun and weather impact.
✔ Bolt & Screw Leakage Sealing
One of the most common issues in metal roofs.
We seal every bolt, screw, and junction using Sealant XT100.
✔ Welding Joint Waterproofing
We seal weak welding areas, panel joints, and overlapping metal sheets.
✔ Rust Treatment & Anti-Corrosion Coating
Rust is treated, cleaned, and covered with protective layer to stop corrosion.
✔ Industrial Shed Waterproofing
Large metal industrial roofs require flexible waterproof membranes capable of handling expansion and vibration.
✔ Factory Roof Waterproofing
High-performance waterproofing for large factory metal roofs exposed to heavy rain and extreme heat.
✔ Container Metal Roof Waterproofing
Shipping containers and storage containers often leak due to rust and metal expansion.
We completely waterproof them with XT100 + AS100.
OUR INDUSTRIAL METAL ROOF SYSTEM
1. Rust Cleaning & Surface Preparation
Remove rust, dust, and loose materials so chemicals bond perfectly.
2. Crack, Gap & Bolt Sealing (XT100)
