Premium Roof Waterproofing Services in Pakistan
The Best Solution for Roof Leakage
Water Seal provides the most reliable roof waterproofing services in Pakistan. If you need expert roof waterproofing services to fix water leakage, dampness, and ceiling cracks we are your trusted partner. We use advanced Polyurethane (PU) and Polyurea coatings that form a seamless, rubber-like barrier on your roof. Unlike traditional bitumen (luk), our professional waterproofing solution is heat-reflective, flexible, and comes with a 10-year warranty, making it the best choice for protecting homes in Faisalabad, Lahore, and other cities from heavy monsoon rains.
What is the Best Method for Roof Waterproofing?
The best method for roof waterproofing depends on the roof condition, budget, and climate. In Pakistan’s hot and monsoon-heavy weather, Polyurea waterproofing is considered the most durable solution due to its seamless application, fast curing, and long lifespan.
For residential buildings, PU (Polyurethane) coating waterproofing is the most commonly recommended method as it offers excellent flexibility, crack-bridging ability, and cost-effective long-term protection against roof leakage.
Traditional methods like Bitumen (Luk) or Mud capability fail within 1-2 years because they crack in the summer heat. In contrast, our expert PU & Polyurea Waterproofing is seamless, flexible, and long-lasting.
Problems We Fix: Why Is Your Roof Leaking?
Your roof faces constant exposure to rain, sunlight, and temperature changes — which leads to serious damage over time.
Here are the most common roof issues homeowners face in Pakistan:
Water Seepage During Heavy Rain
Monsoon rains can be devastating for flat roofs. When water accumulates (ponding) due to poor drainage or uneven surfaces, it creates pressure on the concrete slab. Over time, this standing water penetrates through porous spots, causing ceiling dampness, dripping, and unsightly yellow water stains inside your rooms.
Cracks & Weak Concrete Surfaces
Concrete roofs naturally expand during the hot day and contract at night. This constant thermal movement causes hairline cracks to develop on the surface. These cracks act as open channels for water to travel deep into the structure, rusting the steel reinforcement (saria) and weakening your building’s life.
High Indoor Temperature (Heat Absorption)
In Pakistan, roof surface temperatures can reach up to 60°C - 70°C in summer. Standard concrete absorbs this heat and radiates it into your living rooms, making them feel like an oven. This not only makes living uncomfortable but also drastically increases your electricity and air conditioning bills.
Leaks at Roof Joints & Parapet Walls
The most critical weak spots are the corners where the roof floor meets the boundary wall (parapet). Due to structural movement, these joints often open up. Without proper sealing, rainwater flows down through these gaps, ruining the paint and plaster of your internal walls.
Damaged Old Waterproofing Layers
Many homes still rely on traditional Bitumen (Luk) or mud plastering. Unfortunately, Bitumen becomes brittle and cracks under direct sunlight within a year. We specialize in treating these failed layers by applying modern PU Coatings that are flexible and do not crack under the sun.

3. Polyurea Spray Coating
Polyurea spray coating is a high-performance waterproofing system made from isocyanate and polyamine, forming an instant-cure, high-strength barrier applied using spray technology. It creates a joint-free, extremely durable protective layer that offers superior resistance against water, chemicals, and UV rays.
Best For:
- Industrial and factory roofs
- Commercial buildings and warehouses
- High-traffic and heavy-duty roof areas

Added Benefit: Heat Protection
(Waterproofing + Mild Heat Insulation)
While our primary goal is to stop leaks, our White and Blue PU & Polyurea Coatings offer a significant advantage: Sunlight Reflection.
Because the surface is white and UV-resistant, it naturally reflects solar heat instead of absorbing it. This can help lower your roof’s surface temperature and reduce the load on your air conditioning.
