Karachi’s scorching summers are no secret. With temperatures soaring beyond 40°C and heatwaves becoming more frequent, the city’s residents often find themselves battling unbearable indoor heat. Whether it’s a home, office, or industrial unit, roofs absorb and trap heat, turning buildings into ovens. This is where roof heat proofing services in Karachi come into play — offering a cost-effective and lasting solution to reduce indoor temperatures and energy costs.
In this blog, we’ll explore how heat proofing works, why it’s essential in Karachi, and how Sky Chemical Services can help you protect your property from extreme heat.
Why Roof Heat Proofing Is Essential in Karachi
Karachi’s climate features extended summers, high humidity, and limited tree cover — a recipe for overheating homes and buildings. The urban heat island effect, combined with poor ventilation and direct sun exposure, makes the upper floors of buildings almost unlivable during peak summer.
Here are some reasons why heat proofing is no longer a luxury but a necessity:
-
Lower Indoor Temperature by 5°C to 8°C
-
Reduce AC Usage and Energy Bills
-
Protect Roof Surface from UV Damage
-
Improve Comfort for Residents and Employees

What Is Roof Heat Proofing?
Roof heat proofing is a process in which specialized reflective and insulating materials are applied to the roof’s surface. These materials reflect sunlight and reduce heat absorption, keeping the internal temperature of a building significantly cooler.
There are various types of roof heat proofing solutions used in Karachi, depending on the roof type, condition, and budget.
Popular Roof Heat Proofing Methods
1. Heat Reflective Coating
One of the most popular methods, this involves applying a reflective white or silver coating made from acrylic, elastomeric, or polyurethane-based materials. These coatings:
-
Reflect sunlight
-
Resist UV rays
-
Reduce heat buildup on the roof surface
2. Polyurethane Foam Insulation
A more advanced solution, polyurethane foam is sprayed directly onto the roof and then sealed with a UV-resistant coating. It offers excellent thermal insulation and also helps with minor waterproofing.
3. Thermal Insulating Sheets
These sheets are installed beneath the roof slab or in the ceiling to create a heat barrier. They’re common in industrial buildings and warehouses.
4. Hybrid Heat and Waterproof Coating
In Karachi, where both roof heat and water leakage are common, dual-purpose chemical coatings that offer both heat proofing and waterproofing are a smart choice.
