HOW TO CALCULATE ROOF WATERPROOFING COST
Waterproofing cost is calculated based on:
✔ 1. Total Roof Area (Sq. Ft.)
Most roofs in Karachi range between 600–4,000 sq.ft.
Price is calculated:
Roof length × Roof width = Total area
✔ 2. Roof Condition (Cracks, Damage, Leakage)
If your roof has:
Deep cracks
RCC surface damage
Water absorption
Leakage points
Weak plaster
Then additional crack sealing or repair may be required.
✔ 3. Waterproofing System Selected
We use advanced materials depending on your roof:
Sealant XT100 (Crack sealing)
Aquashield AS100 (Liquid rubber coating / waterproofing membrane)
UV Reflector 101 (Cool roof reflective topcoat)
✔ 4. Number of Required Coats
RCC roofs usually need:
2 coats of AS100
1–2 coats of UV101
Crack sealing with XT100
Metal roofs & warehouses may require additional layers.
✔ 5. Access, Height & Site Conditions
Some roofs require extra safety measures, rope access or preparation.
