PU spray, also called polyurethane spray, offers dual benefits: waterproofing and insulation. It costs between PKR 90–140 per sq ft depending on foam thickness and roof condition.
Bitumen Membrane Waterproofing Cost
Bitumen membranes are heat-applied and create a durable seal. Their price usually falls in the range of PKR 100–130 per sq ft, including installation.
Cementitious Waterproofing Rate
This is a low-cost option (around PKR 25–50 per sq ft) and suitable for small residential roofs. However, it requires frequent reapplication.
Transparent Waterproofing Coating Price
Best for rooftops with tiles or visible surfaces, transparent coatings cost between PKR 60–85 per sq ft and offer aesthetic plus waterproofing benefits.

Residential vs Commercial Waterproofing Rates
Residential buildings typically cost less per square foot due to smaller areas and simpler surfaces. In contrast, industrial and commercial waterproofing often requires specialized equipment and higher-grade materials, increasing the price.
Additional Services That Can Increase the Cost
Roof Crack Repair
If your roof has visible cracks or weak joints, contractors may charge extra for sealant applications or concrete patchwork.
Thermal Insulation
Some customers opt for combined heat-proofing and waterproofing, especially with PU spray. This adds to the cost but boosts energy efficiency.
Drainage Solutions
Clogged or poorly designed drains can worsen water pooling. Upgrading drainage systems may cost more but ensures long-term roof health.
