Welcome to CoolTech Roof Heat & Water Proofing

We have been serving in the industry for the past 25 years!

We take pride in being one of the pioneers of roof heat proofing in Pakistan. Our company was established in the year 2000.

Our roots in the chemical industry can be traced back to our ancestors who were prominent importers of chemicals. When Pakistan gained independence, our founder's grandfather, the late Mr. Abdul Khaliq Gandhakwala, was among the first individuals to open a chemical outlet in Jodia Bazar, Karachi. His reputation is well-known throughout Pakistan among chemical-related industrialists and businessmen.

Building upon our expertise in the chemical field, we ventured into a new business that caters to the needs of households, factories, offices, hotels, schools, hospitals, and other locations. Our roof coating is a blend of various chemicals, including sunblock agents sourced from Pakistan, Korea, China, and Germany. This technology originated in the USA, Gulf countries, Saudi Arabia, and other hot regions in the early 1980s. CoolTech introduced this innovative facility to Pakistan in 2000. With our advanced techniques, we can cover approximately 10,000 square feet of clean area in a single day, without causing any damage to the roof surface or creating noise disturbances. After the coating process, your roof can be used just as conveniently as before.

At CoolTech, our mission is to provide exceptional roof heat and waterproofing solutions, ensuring ultimate protection, comfort, and customer satisfaction. We deliver superior craftsmanship, utilize cutting-edge technologies, and prioritize environmental responsibility, all while surpassing industry standards and meeting each client's unique needs.

Our vision is to be the leading provider of innovative roof heat and waterproofing solutions, setting new industry benchmarks for excellence. We aim to transform the way properties are protected, ensuring optimal comfort, durability, and customer satisfaction, while promoting environmental sustainability.

Our values encompass integrity, professionalism, innovation, and environmental responsibility. We prioritize customer satisfaction by delivering exceptional craftsmanship, utilizing cutting-edge technologies, and promoting sustainable practices. Our commitment to excellence drives us to surpass industry standards and provide superior roof heat and waterproofing solutions.

We have been providing heat proofing services for the past 25 years. Our expertise lies in offering three different types of ceramic-based heat reflective coatings that not only reduce the temperature of buildings but also result in significant electricity bill savings. Additionally, we offer different types of waterproofing services that, combined with our coating solutions, have proven to be highly effective in addressing seepage issues.


Benefits & Importance

  • It reduces the temperature inside the building by 3-5 degrees, depending on the prevailing climatic conditions.
  • The coating can lower the roof surface temperature by up to 50%.
  • It increases the effective R-value of insulation, enhancing the overall thermal efficiency of the building.
  • By reducing the heat load on the building, it helps save on the cost of air conditioning.
  • The coating provides a cost-effective solution for extending the life of the roof, allowing for re-coating instead of complete replacement.
  • In areas without air conditioning, the coating creates a more comfortable environment.
  • The coating helps slow down the premature aging of the roof caused by high surface temperatures and UV degradation, resulting in reduced overall roof life-cycle costs.
  • It reduces respiratory health risks and the likelihood of heat-related deaths, particularly in regions prone to heatwaves, such as Karachi in 2015.
  • In the case of waterproofing services, the coating acts as the first layer of defense against UV radiation, reducing thermal shocks and acting as a water-resistant barrier to prevent water penetration.


CoolTech Coating is 100% Environmental Friendly!

Our coating is not only highly effective but also 100% environmentally friendly (green). By using our coating, we contribute to the reduction of landfill materials. It is worth noting that roofing materials account for at least 10% of landfill waste. Moreover, our coating helps conserve energy, benefiting both building owners and utility suppliers. It plays a significant role in reducing the carbon footprint of buildings by lowering CO2 emissions. Additionally, it minimizes the overall environmental burden.

Waterproof Sealing Tape

A lead replacement, self-adhesive flashing strip, ideal for emergency repairs. Instant waterproof seal once applied. Grey finish. Quick and easy to use. For use on wood, glass, metal, brick and cement. Curing time immediate at normal temperature.

The surfaces that need to be sealed must be dry, able to bear load, and free from grease and dust. Start by removing any loose dust and dirt using a wire brush and soft broom in the area where you plan to apply the COOLTECH Waterproof Sealing Tape. Unroll the tape and cut it to the desired length. Peel off the backing strip and place the adhesive side onto the properly prepared substrate. To prevent air pockets and creases and ensure a tight seal, gently press down the tape using a roller or your fingertips. Pay special attention to pressing down the edges and ends of the tape as it is crucial for a secure seal.
