Roof heat is the biggest comfort and bill problem in Indian homes. Here is what actually moves the needle.
If your top floor is several degrees hotter than the rest of the house, the roof is almost always the culprit. Dark concrete absorbs intense sun and re-radiates it indoors for hours.
Reflect, insulate, shade
Three levers work together: reflective coatings bounce sunlight away, insulation slows heat transfer, and shading keeps the surface cooler. The right mix depends on your roof and budget.
What to expect
A good cool-roof system can cut roof surface temperature substantially and noticeably reduce indoor heat and AC load. Results vary with insulation and layout — which is why we measure before and after.
