Using an umbrella or a wide-brimmed straw hat on a hot day at the beach helps keep the sun at bay. Technology is bringing cover-ups to roofing as well. These cool-roof coatings have advanced in recent years, and more developments are underway. Elastomeric sealants, foam sprays, ceramic-based paints and even "recycled waste cooking oil" treatments are making gains in providing ways to cool existing roofs by applying coats of overlay that reflect heat away . Built Up Roofing (BUR) is one method for applying cool-roof surface coatings over traditional asphalt or tar roofing. Different claims regarding ease of application, durability and energy savings vary by manufacturer, but researching cool-roof overlays or coatings and consulting with a local roofing contractor and local building codes can help in sorting through what's working well in different regions.

A technology on the flipside of an overlay is a roof underpinning, or sub-roof system called a radiant barrier. This under-the-roof application involves installing a reflective material, such as aluminum, or even a specialized reflective spray treatment that's installed into an attic or space between a home's interior and the roof. These act as barriers to keep heat up and out of a home. Costs vary from about 15 to 75 cents per square foot, but those with added insulating features can cost more. But with a possible savings of about Rs14000 annually (depending on the region), the installation fees may be worth the price.



Roofing with slate tiles is a centuries-old European tradition that made its way to the Americas in the early 17th century. Slate is durable and beautiful, with a natural color range, and it lasts a long time with little maintenance. Light colored and earth-toned slate help in reducing the heat absorbed by a building because it has natural reflective properties. It also wears to a nice finish over time.

Some downsides to using slate are its upscale price and heavy weight. While slate is among the most beautiful roofing treatments, especially in re-creating Mediterranean and Spanish architecture styles, it is costly and harder to transport than lighter, less breakable materials. Its extensive use worldwide is due to its popularity as a cool roofing material for hot climates and its widespread availability. In areas without natural slate reserves, it is an expensive option. Reclaimed or salvage slate is available in some areas, but installation and transport costs still add up.



Most regions of Kerala, Tamilnadu, Andhra Pradesh and the Indian northwest have tons of heat and sunshine, and an abundance of Mission- or terracotta roofs. Some ancient sites have clay and terracotta tiles that have survived the test of time and relentless centuries baking in the sun. Basic clay roofing is light in color and doesn't retain as much heat as a darker roof. Modern clay tiles have paint treatments to make them look like more expensive slate or traditional terracotta and to add weatherproofing and reflective capabilities.
