Introduction:

Now that summer has here, it's important to make sure your house is prepared to withstand the blistering heat waves and soaring temperatures to come. While there are many ways to release the heat that has been trapped in your home and make it seem cold, individuals who live in southern regions of the country are totally reliant on air conditioners throughout the summer. Unfortunately, operating an air conditioner continuously is not a practical solution due to the frequent power outages and high electricity costs. Your greatest alternative, especially if you reside on the top level, is definitely to get skilled roof heatproofing to combat the escalating heat. How does roof heat proofing operate then?

Simply put, a barrier is added to your roof in the form of an additional layer of heat-resistant material. This substance will both absorb water and heat, insulating your roof and preventing heat from escaping into your home.

COMMON ROOF HEATPROOFING TECHNIQUES IN PAKISTAN

These are some of the methods that are most frequently used to heatproof roofs.

HEAT RESISTANT ROOFING SHEET INSTALLATION

Installing heat-resistant roofing sheets is one of the most often used methods of heatproofing a roof. These sheets from a manufacturer are quite good at shielding your house from solar rays. They are often constructed using corrugated patterns and are regarded as one of the greatest solutions for people who want to waterproof and insulate their roofs.

Several varieties of heat-proof sheets are utilised across Pakistan, however some of the most often used ones on the market are polyester painted sheet, galvanised steel sheet, and PVC plastisol sheet.

These lightweight corrugated heat-proofing sheets can readily endure adverse weather conditions. Also, they are cost-effective, long-lasting, sustainable, energy-efficient, and most significantly, long-lasting.

MODIFIED BITUMEN MEMBRANE APPLICATION

In Pakistan, this is yet another popular method of heatproofing roofs. As most roofs of residential buildings in the nation are flat, applying modified bitumen rolls to their surface may dramatically reduce heat and water absorption, simultaneously heatproofing and waterproofing your property. These bitumen rolls are created by melting asphalt and other adhesives, which are then applied to the roof surface until the entire thing is coated.

The majority of homeowners chose to paint their molten bitumen membrane, which is black, with white paint to further heat-proof their roofs while preserving their aesthetic value.

PAINT OR CHEMICALS FOR ROOF COOLING

Another well-liked and inexpensive method for heatproofing your roof is by painting it white with reflecting paint. Although having the appearance of standard white paint, this heatproofing substance has two primary functions. At the beginning, it aids in reflecting ultraviolet rays, keeping your house cool. Second, by raising the concrete slab's resistivity index, it lowers the temperature of the roof.

This reflective paint, which is also known as roof cooling coating, may be used on both flat and sloped roofs. Additionally, using a standard paintbrush, roller brush, mop, or spray machine, many coats of this chemical must be sprayed to the surface. Due to its ability to reflect sunlight, elastomeric coating is perhaps the most popular option for heat proofing roofs in Pakistan.

CHOOSING BUILT-UP ROOFING (BUR)

Built-up roofing, commonly referred to as BUR, is typically installed on flat or low-slope roofs to keep the house cool during the sweltering summer months. Bitumen, ply sheets, and reinforcing fabric are layered alternately to heat proof the roof. Built-up roofing's top layer is made out of rocks, marble, and gravel aggregate to prevent heat absorption into the roof. Also, the minerals serve as a barrier against moisture, totally sealing the surface to prevent moisture from penetrating the roof.

The top layer of built-up roofing is fire resistant in addition to waterproofing your roof and shielding it from UV radiation.
