Cool Roof & Heat Reflective Painting in Chennai
Reflective cool tiles and roof coatings that significantly reduce roof temperature.
Overview
Living on the top floor in Chennai can be unbearable during summer. Our cool roof painting services offer a cost-effective way to reduce radiant heat. By applying a high Solar Reflective Index (SRI > 105) coating, we reflect up to 90% of sunlight, preventing it from being absorbed by the concrete slab.
Cool Roof Paint vs. Weathering Tiles
Many homeowners ask which is better. Here is a quick comparison:
- Cool Roof Paint: Seamless (no joints for water to seep), lighter weight (good for old buildings), and highly reflective. Needs recoating every 5-7 years.
- White Cool Tiles: Durable and hard, but joints can open up over time causing leaks. Adds significant weight to the roof.
For most existing buildings, Cool Roof Coating is the superior choice as it waterproofs the roof while cooling it, without adding dead load.
Benefits of Cool Roof Coating
Apart from immediate comfort, high-SRI coatings provide:
- Energy Savings: Reduces the load on air conditioners, cutting down electricity bills by up to 30%.
- Concrete Protection: Reduces thermal shock (expansion/contraction), preventing future cracks in the roof slab.
- Anti-Fungal Properties: Most cool roof paints come with additives that prevent moss and algae growth.

Frequently Asked Questions
Can I walk on the roof after painting?
Yes, our cool roof coatings are designed to be abrasion-resistant and walkable for regular maintenance and usage.
How much temperature difference can I feel?
You can expect a significant drop of 5°C to 8°C in indoor room temperature during peak summer afternoons.
Does this work on existing weathered tiles?
Yes, we can apply the coating over old weathering course tiles effectively after proper cleaning and primer application.
How long does the cool roof coating last?
With proper maintenance, high-SRI cool roof coatings typically last between 5 to 7 years before needing a top-coat refresher.
Is this effective during monsoon season?
While its primary function is heat reflection, the coating also provides an additional layer of water resistance, helping to reduce minor dampness.
How many years does the cool roof coating last?
Our high-SRI cool roof coatings typically have a lifespan of 5-7 years, provided they are maintained with occasional cleaning.
Can I apply this myself?
While simple, professional application is recommended to ensure the correct thickness (micron level) and proper bonding, which is crucial for durability.
Does the roof become slippery?
No, the coating dries to a matte finish. However, like any wet surface, caution is advised during rains. We can add anti-skid granules if requested.
Will this reduce my electricity bill?
Yes, by reducing the internal temperature, your AC compressor works less, potentially lowering your summer electricity bills by up to 25%.
Is any maintenance required after application?
Minimal maintenance is needed. Just ensuring the roof is kept clean of heavy dust and leaves will maintain its reflective efficiency.
