Viral Rooftop Cooling Hack Claims To Reduce Indoor Heat By 15°C For Under ₹800
Viral Rooftop Cooling Hack Claims To Reduce Indoor Heat By 15°C For Under ₹800
As several parts of India continue to battle extreme summer temperatures, a viral video showing a low-cost rooftop cooling method has caught the attention of social media users. In the video, a man claims he managed to reduce indoor heat by nearly 15 degrees Celsius using a simple roof coating that cost less than ₹800.
The video has gained popularity online as many households search for affordable ways to stay cool during the ongoing heatwave without depending heavily on expensive air conditioners and rising electricity bills.
Simple DIY Roof Cooling Method Goes Viral
Instead of spending ₹20,000 to ₹30,000 on an air conditioner, the man demonstrated how he created a heat-reflective coating using three commonly available materials:
- White chuna (lime powder)
- Fixit URP
- Fevicol binder
According to him, the mixture forms a reflective layer on the rooftop that reduces heat absorption from direct sunlight, helping keep rooms cooler during peak summer temperatures.
He claimed that even when outside temperatures touched 45°C, the rooftop treatment significantly reduced indoor heat and improved comfort levels inside the house.
How The Cooling Mixture Was Prepared
In the viral clip, the man explained the full process step by step.
Step 1: Mixing The Ingredients
He first mixed white chuna with water to create a smooth liquid base. He then added Fixit URP and a small amount of Fevicol binder to improve adhesion and durability.
Step 2: Cleaning The Roof
Before applying the coating, the rooftop surface was cleaned thoroughly to remove dust and dirt.
Step 3: Applying The Coating
Using a brush and paint roller, the mixture was spread evenly across the roof. He suggested applying multiple layers for better cooling performance.
Step 4: Drying Under Sunlight
After application, the roof was left to dry completely under direct sunlight.
Why White Roof Coatings Help During Heatwaves
Experts often explain that lighter roof surfaces absorb less heat compared to dark concrete roofs. White coatings reflect a larger amount of solar radiation, helping reduce rooftop temperatures and limiting heat transfer into rooms below.
This is why reflective roof paints and lime-based coatings are commonly used in many hot regions during extreme summers.
“Why Spend ₹20,000–30,000 On ACs?”
One statement from the video especially grabbed attention online. The man questioned why people spend huge amounts on air conditioners and electricity bills when simple traditional cooling methods may also provide relief at a much lower cost.
The comment quickly resonated with users dealing with rising temperatures and increasing power expenses.
Many people praised the hack for being:
- Budget-friendly
- Easy to apply
- Energy-saving
- Useful during heatwaves
However, some users also noted that the effectiveness may vary depending on factors such as roof material, local weather conditions and the quality of products used.
DIY Cooling Techniques Becoming More Popular
With temperatures soaring across several Indian states, many households are increasingly turning towards low-cost cooling alternatives such as:
- White roof coatings
- Bamboo shades
- Heat-reflective sheets
- Water sprinkling systems
- Natural ventilation techniques
These methods are being seen as practical ways to reduce indoor heat and cut down electricity consumption during summer months.
Can Roof Cooling Replace An Air Conditioner?
While such DIY cooling techniques may help reduce indoor temperatures and improve comfort, experts say they may not completely replace air conditioners during severe heatwaves.
Still, these methods can play an important role in:
- Lowering roof temperature
- Reducing heat entering the house
- Improving indoor comfort
- Saving electricity
For many families, especially in extremely hot regions, affordable rooftop cooling solutions are emerging as useful supplementary options to tackle rising summer temperatures.
