Summer is finally here, which means you need to make sure your home is ready to tolerate sweltering heat waves and soaring temperatures in the coming months. While there are quite a few ways to get rid of the trapped heat and make your home feel cool, people living in southern parts of the country are completely dependent on air conditioners during summer. However, owing to frequent power breakdowns and hefty utility bills, running an air conditioner 24/7 is not a viable option. To tackle the worsening heat, opting for professional roof heatproofing is probably your best option – especially if you live on the top floor.
So, how does roof heat proofing work?
To put it simply, an additional layer of heat-resistant material is added to your roof to act as a barrier. This material will absorb both heat and water, thus protecting your roof and preventing the residual heat from entering your home.
A number of different companies, both small and big, are providing roof heat proofing services across Pakistan. However, since most homeowners are unaware of how simple, affordable, and hassle-free this home improvement project actually is, we at Zameen.com have decided to bring you a detailed guide on how to heat-proof your roof this summer.
Let’s get started.
Popular Methods for Roof Heatproofing in Pakistan
These are some of the most popular techniques for heatproofing your roof.
Installing Heat Resistant Roofing Sheets
One of the most popular ways of heatproofing your roof is to install heat-resistant roofing sheets. These factory-made sheets are highly effective for protecting your home from sun radiation. They are usually made with corrugated patterns and are considered one of the best options for those looking to insulate as well as waterproof their roofs.
There are different types of heat-proof sheets used across Pakistan, though Polyester Painted Sheet, Galvanised Steel Sheet, and PVC Plastisol Sheet are some of the most popular options available in the market.
These corrugated heat-proofing sheets are lightweight and can easily withstand harsh weather conditions. They are also long-lasting, durable, sustainable, energy-efficient, and most importantly, affordable.

Applying Modified Bitumen Membrane
This is yet another well-known roof heatproofing treatment in Pakistan.
Since roofs in houses across the country are usually flat, the application of modified bitumen rolls on its surface can significantly reduce the absorption of heat and water, simultaneously heatproofing and waterproofing your home. These bitumen rolls are made up of asphalt and other adhesives that are melted and spread across the surface of the roof until it is completely coated.
Most homeowners prefer painting them black, molten bitumen membrane with white paint to further heat-proof the roof while maintaining its aesthetic appeal.
Using Roof Cooling Chemical or Paint
Using reflective white paint to heat-proof your roof is also a popular yet affordable technique. Though it may appear like regular white paint, this heatproofing chemical serves two main purposes. First, it helps reflect the ultra-violet rays, thus keeping your home cool. Secondly, it helps bring down the temperature of the roof by increasing the resistivity index of the concrete slab.
Also referred to as roof cooling coating, this reflective paint is suitable for both flat and pitched roofs. Moreover, multiple layers of this chemical have to be applied to the surface using a regular paintbrush, roller brush, a mop, or a spray machine.
In Pakistan, Elastomeric coating is perhaps the most common choice for roof heat proofing treatment owing to its solar reflective property.
Choosing Built-up Roofing (BUR)
Built-up roofing, which is also known by its abbreviation BUR, is mostly used on flat or low-slope roofs to keep the house cool during hot summer months. This roof heat proofing treatment comprises alternate layers of bitumen, ply sheets, and reinforcing fabric. The top layer of built-up roofing comprises rocks, marble, and gravel aggregate to keep the heat from absorbing into the roof. The minerals also act as a protective layer against moisture, keeping it from seeping into the roof by completely sealing the surface.
In addition to waterproofing your roof and protecting it from ultraviolet rays, the top layer of built-up roofing is also resistant to fire.
Built-up roofing is very durable, easy to maintain, and relatively inexpensive.
To conclude, if your home gets really hot in summer regardless of how well-ventilated it is, you should consider opting for one of the above-mentioned treatments. Just contact a reputable roof heat proofing company to get an estimate and weigh all of your options before making the final choice.
