Want to protect yourself and your loved ones from the scorching heat of Karachi? There could be many options, such as installing air coolers or air conditioners, but these might come along with a massive operational cost. If you are looking for a cost-effective solution, then roof heat proofing will top the list. It is increasingly becoming a standard solution for heat protection.
Before getting a roof heatproofing service, you need to understand your roof type.
Every roof is different; this is why every roof requires another type of heat proofing service.
There are two main types of roofs widely available in Karachi.
Heat Proofing For Steel Shields
A house with a steel shield would be hotter than the one with a concrete roof, steel being the core reason for it.
If your home has a steel shield roof, then getting heat proofing might be a little more technical than the usual heatproofing, especially in the case of corrugated and galvanized roofs, due to the uneven leveling of the rooftops and the components used to make the rooftops. Steel roofs are also slanted, making it even more challenging to have a regular roof heat proofing.
Each type of steel shield has its heath absorption rate depending upon the steel roofs’ structure and composition.
Chemical heat proofing compliments the steel shields to protect it from the weather. The chemicals are white, so you would not have to compromise on the outlook of your home. In some research, it has also been stated that the heat absorption is directly linked with the color of the roof, where black absorbs the highest amount of solar energy, and white absorbs the least solar energy. These chemicals are made up of solar reflective pigmented technology, reflecting the solar light resulting in lighter house temperature. The best part about these chemicals is that these are not harmful to the environment and the people living in the house.
This type of heat proofing makes the house cooler and contributes to reducing electricity consumption and billing.
Heat Proofing For Concrete Ceilings
If you live on the top floor, you know exactly how hot your house temperature could get when the Sun is shining brightly. The heat absorption tendency in concrete is high, which results in higher temperatures inside the houses. During the daytime, concrete absorbs the heat, and during nights it releases that heat. As a result of the air stability below the roof, the air in the rooms gets hotter. If you are using a ceiling fan, then it would just push the hot air in a downward direction.
There are three main options available for concrete roof heatproofing.
One option is to apply a 40 mm layer of gravel on the rooftop. It is also known as the railway jelly. This confines the heat from entering or touching the rooftop, but it might also restrict you from walking on your rooftops.
The second option is to get bituminous sheets with silver coating. This comes with two benefits; protection from heat and water leakage during the Monsoon season.
The last and the most widely used option is a white-colored pigment used for roof heat proofing the concrete tops, which are made from Sun reflective coating technology. This acts as a membrane between the sunlight and the rooftop while confining the heat to enter inside the house.
Regardless of the type of roof heat proofing, you opt for; you would not have to wait for days to get your life back to normal. Heat proofing hardly takes a couple of hours to dry up, depending on the service provider. Hence, it is time-effective along with being easy on your pocket.
