Our Roof Repair & Renovation Process:

1. Roof Inspection & Damage Assessment
We inspect cracks, joints, weak points, and leakage origins using professional tools to identify all hidden and visible issues.

We treat corners, parapet joints, expansion gaps, and plumbing areas — the most common leak sources. Damaged or hollow areas are repaired for a solid base.
4. Waterproof Coating – Aquashield AS100
After repairing the roof surface, we apply Aquashield AS100 liquid rubber coating to create a seamless, flexible waterproof membrane that prevents future leaks.
5. UV Protection & Heat Reduction (Optional)
For heat-exposed roofs, we add UV Reflector 101 to protect the surface from UV damage while reducing temperature absorption.

How to Fix Repair Roof Leakage in Monsoon/Rainy Season?
The best practice is to fix, repair, waterproof the roof leakage before monsoon or rainy season to avoid structure or any further losses.
Even though in case of emergency repairing a roof during the monsoon or rainy season requires quick, temporary fixes to stop water
ingress, as permanent repairs (like cement work or major, heat-applied waterproofing) are best done in dry conditions. The primary goal during rains is to prevent further damage to the structure until the rain stops.
KCS Roofing Specialist - Repairing a roof during the monsoon or rainy season needs a careful, damage-control approach. Full-scale work is risky in rain, but temporary + targeted repairs can stop leaks and prevent structural damage until permanent treatment is possible.
Below is a practical, KCS Waterproofing – Roofing Specialist step-by-step guide specifically suitable for monsoon conditions.
Identify the Leak Source (Priority Step. During rain, leaks become visible—use this to your advantage.
Common monsoon leak points: RCC roof cracks and hairline gaps, Expansion joints, Parapet wall joints, Pipe sleeves & drain outlets (nahani), and Old waterproofing layer failures
➡️ Mark the leaking spots once rain slows or stops.
Emergency Leak Stopping (Wet Surface Solutions) In monsoon, surfaces are often damp—normal materials won’t work.
Use only rain-compatible materials:
Polyurethane (PU) sealant – works on slightly wet surfaces, Bituminous instant sealant / rubberized paste, Cement-based quick-setting leak plugs for active water flow, and Plaster of paris quick setting powders
Where to apply:
Open cracks, Joint gaps, Pipe bases, and Water-entry points. Better to paste a cloth bandages on major cracks, leaks, joints
⚠️ Avoid normal cement or acrylic coatings during rain—they will fail.
Temporary Crack & Joint Treatment for immediate protection until dry weather:
Clean loose debris (no pressure washing in rain)
Apply PU sealant deep into cracks
Reinforce with polyester mesh / fiber tape if possible
Seal parapet wall & slab junctions (most ignored leak zone)
This can safely last one full monsoon season if done correctly.
Drainage Fix (Very Important in Rainy Season) Most monsoon roof damage happens due to standing water, not rain itself.
Immediate actions:
Clear all roof drains & rainwater pipes
Ensure proper slope towards outlets
Remove ponding water after every heavy rain
Even the best waterproofing fails if water stays on the roof.
Metal / Sheet Roof Repair in Rain for metal, shed, or container roofs:
Tighten loose bolts during dry intervals
Apply rubberized leak-proof tape on joints
Use PU sealant on screw points
Avoid welding during rain (unsafe & ineffective)
What NOT to Do in Monsoon ❌ Do not apply full waterproofing membranes
Do not use cement slurry or tile mortar
Do not apply heat proofing or reflective coatings
Do not cover leaks with plastic sheets (traps moisture)
These cause hidden damage and future peeling.
Best Long-Term Strategy (After Monsoon) Once rain stops and the roof dries completely:
Crack repair with polymer-modified mortar
Complete RCC roof waterproofing system
Protective topcoat for UV + water resistance
This ensures 5–10 years leak-free performance.
KCS Roofing Specialist Expert Tip Monsoon repairs should be treated as damage control, not permanent solutions.
A correctly executed temporary repair prevents:
Ceiling damage
Electrical short circuits
Concrete corrosion
Mold and seepage spreadDon’t let small cracks turn into costly repairs. Contact KCS Roofing Specialist today for roof leak repair and waterproofing services in Karachi.
