Summers can be oppressive especially if roofs are not insulated. The roof of the building stays exposed to the scorching heat of the sun to absorb temperature. This, in turn heats the room below which takes longer to cool.Anyone who has lived on the uppermost floor of a building in hot cities, might have experienced the discomfort of significantly high temperatures during the summer as compared to other floors in the same building.
Usually traditional roofs are made up of concrete or asphalt cinder blocks and are topped with flat, tar covered roofing. Concrete, being a dense material, doesn’t cool easily. Such surfaces absorb the incident solar radiation, transferring it to the interiors of the room.
When the fan is switched on, the hot air from the roof gets circulated inside the room. It takes a long time even for an air conditioner to cool such a room resulting in higher energy consumption. Although there are multiple ways to reduce this phenomenon ranging from cool roofs to green roofs to metal shades, cool roofs are considered the most cost effective and easiest to manage.Cool roofs have the ability to reflect and reject heat because such surfaces are coated with paint which has properties of high solar reflectance and emittance. White coloured roof surfaces have a high reflectivity, which can dissipate the incoming solar rays to a large extent.
Comparing Cool Roofs and Traditional Roofs
Choosing between cool roofs and traditional roofs depends on several factors, including your energy efficiency goals, budget, and personal preferences. Cool roofs are ideal for those seeking savings and environmental benefits as well as increased thermal comfort.
| Aspect | Cool Roofs | Traditional Roofs |
| Heat reflection | Reflect sunlight and absorb less heat | Absorb sunlight and retain more heat |
| Energy efficiency | Reduce cooling needs, lower energy consumption | Increase cooling needs, higher energy consumption |
| Temperature control | Help maintain lower indoor temperatures | Less effective in maintaining lower indoor temperatures |
| Environmental impact | Reduce urban heat island effect, decrease carbon emissions | Contribute to urban heat island effect, increase emissions |
| Lifespan | roof coats made with elastomeric polymers can increase shelf life of roofs | lower shelf life |
| Installation cost | Slightly higher upfront cost due to specialized materials | Lower upfront cost |
| Maintenance | Require periodic cleaning and inspection | Require periodic cleaning and inspection |
| Roofing materials | Options include reflective coatings, tiles, and membranes | Wide range of options including asphalt, shingles, tiles |
| Geographic suitability | Most effective in hot climates and sunny regions | Suitable for various climates and regions |
| Aesthetics | Available in various colors and designs | Traditional appearance with limited design options |
