Do you like to stay in a cool environment and enjoy your time with your loved ones or friends? Well, we’ve got the perfect solution for you. Heat-proofing services: Insulation, reflective coatings, and barrier applications ensure temperature control, energy efficiency, and comfort in buildings.
Roof Heat Proofing is feasible for residential or commercial structures. It can be applied on different types of rooftops, including mansard, gable, flat, and hip. Easy application, reduced energy costs, higher aesthetics, and improved indoor comfort are some of its benefits. If you are in search of a reliable company, contact Sky Chemical Services.
Why is Color Important for Rooftops?
The roof’s color can change the temperature of your home by a huge margin. According to research, light-colored roofs reflect more heat whereas dark-colored roofs reflect less. White is the most reflective of all colors, having an SRI (Solar Reflective Index) of 84 and TSR (Total Solar Reflectance) of 70.
Most homeowners apply roof colors according to the environment. For example, a blue-colored rooftop looks attractive with a lake or pond nearby. Similarly, a green-top corresponds well with forests and woodlands. Colored rooftops render a distinctive look to the bystander.
In hot places, like Karachi, dark colors should be avoided due to excessive humidity, more cleaning requirements, premature deterioration, and more. The resale value of a structure also diminishes significantly. If you want to improve your structure’s interior temperatures and make it more energy-efficient, opt for light colors.

Solid Roof Heat Proofing
Thermal insulation is the key component used in roof heat proofing. Due to changing insulation standards across the globe, the use and importance of insulation materials have increased, ensuring higher demands to reduce energy loss for cooling.
Most of the insulation materials possess thermal characteristics and mechanical properties. Some common types of insulation materials include:
- Polyurethane Foam
- Stone Wool
- Expanded Polystyrene
- Extruded Polystyrene
Advantages of Solid Heat Proofing Materials
Polyurethane Foam (PUR) is made from PU foam combined with isocyanate catalyst. It is a universal and efficient solution for different types of roofs. This foam forms a flexible and long-lasting layer of monolithic membrane layer. It lasts for 20-22 years after installation.
Benefits
- Low lambda value (0.023 – 0.028)
- High compressive strength
- Fire-resistant
- Lightweight (30-60 kg/m3)
Stone Wool Roofing is produced from basalt stone fibers and chalk. It is preferable for high-temperature areas, especially where fire resistance is required. It is used for different purposes, including firestop wall, roof insulation, and more. This insulation offers a better density than glass wool. Lastly, it prohibits sound from travelling through.
Benefits
- Non-combustible
- Low lambda value (0.031 – 0.044)
- Non-toxic
- Moisture-resistant
- High acoustic performance
Also called Styrofoam, expanded polystyrene (EPS) combines a polymer infused with a foaming agent. It is mostly used in insulated concrete forms and structured insulated panels. It is approved for ground contact and does not degrade over time.
Benefits
Easy to transport
- Durable
- Moisture-resistant
- Sound-proof
Extruded polystyrene (XPS) is a plastic roofing insulation that complies with ASTM C578, a primary polystyrene insulation. It is mostly used with single ply membranes. Furthermore, it retains the R-value and energy-saving capability after exposure to moisture.
Benefits
- Damage-resistant
- Environmentally-friendly
- High compressive strength
- Easy to apply
- Recyclable
Liquid Heat Proofing
Another method to reduce heat transfer through roofs is ‘Liquid Heat Proofing’. As stated before, white color is the most reflective of all, having a solar reflective index of 84. Different coatings are applied on the roof substrates to create a UV resistant, seamless membrane. These coatings are ideal for pitched and flat roof constructions and are applied on:
- EDPM
- Modified bitumen
- Built-up roofs (BUR)
- PVC
- Concrete
- TPO
- Others

Other Methods for Roof Heat Proofing
Apart from liquid and solid roof heat proofing, there are other methods, including:
- Green roofs
- Standing-seam metal roofs
- Built-up roofs
- Spray polyurethane foam roofs
- Tiles (slate, clay, etc.)
- Shingles (metal, polymer, wood, asphalt, etc.)
Conclusion
Selecting the best roof heat proofing company in Karachi is a tough ask. Quality of work, cost, and other factors have to be taken into consideration before making an informed decision. Connect with Sky Chemical Services for the best results.
