Cool Roof Coating – Assimilating Money and Time


A roof, the highest part of a house, catches the brunt of wind forces,  wind effects, rain to name a few. This stringent point for houses need to be strong, they need to keep water out and they have to stay in the house, not collapse, and not cause other parts of a house to fail.

There are three vital aspects of your roof: the covering that keeps your house dry, all the structure that supports the covering and maintains the shape of the roof, and the connections between the roof structure and the walls below. When you evaluate the ability of your roof to defend your home against a hurricane, you need to consider all of the elements of a roof because they all play vital, essential roles in protecting your house.

Over time several experimentation has been done for the roofing innovation, for now so keeping in mind frequent weather changes and ecological balance. One such concept is that of cool roofing which includes the system of cool roof coating. Cool roofs reflect sunlight and absorb less solar heat than a standard roof, lowering the temperature of your roof and therefore your home. Materials vary, as do efficacy and price.

The edge of the system

Cool roofs offer a variety of benefits for both residential and commercial buildings. They help decrease cooling bills by lowering internal temperatures, lower the temperature in areas without air conditioning, and typically extend the life of your roof. They even help lower air temperatures, benefiting the environment. These benefits all arise from the cool roof’s surface temperature being significantly cooler than a traditional roof, to the tune of 50 degrees or more during summer months. This helps lower ambient temperatures within the home, which helps reduce cooling bills and keep spaces without air conditioning cooler.

The degree of savings and lower internal temperatures relies on a variety of factors, including the type of HVAC system you use, the amount and quality of insulation within your roof, and your local climate.

Advantage of cool roof coating:

  • Reduce the cost of energy used for cooling by 10 to 30 percent.
  • Wall applications reduce the cost of energy used for cooling up to an additional six percent.
  • Can be applied on walls, low slope roofs, steep-sloped roofs.
  • Replacement of entire roof or wall system not required – simply patch and apply.
  • Can be sprayed with the commercial sprayer or applied with  to 1-inch nap paint roller.
  • Excellent adhesion allows for use on varied surfaces: aluminum, asphalt emulsions, concrete, foam roofing, galvanic metals, glass, plastics, wood, stucco, and brick.
  • Increases in occupant comfort and productivity, especially in non-air conditioned areas.
  • Decreases roof maintenance costs by coating and protecting roofing materials and reducing up to 84 percent of solar heat adsorption, thereby greatly reducing surface temperatures.
  • May contribute to Leadership in Energy & Environmental Design (LEED) certification
  • Addresses air pollution and global warming concerns, and contributes to the reduction of the local “Urban Heat Island Effect.”

Installation of a Cool Roof: Facts to consider

When deciding whether to install a cool roof, you’ll need to determine whether the cost will justify the energy savings. How much energy you will save depends on several factors such as your home’s climate and environment, how well insulated your current roof is, the type of roof you have, and the efficiency of your heating and cooling system.



If you are building a new home, you can decide during the planning phase what type of roof to install and whether it should be a cool roof. If you want to convert an existing roof into a cool roof, you have three basic options:

  • Retrofit the roof with specialized heat-reflective material
  • Re-cover the roof with a new waterproofing surface (such as tile coating)
  • Replace the roof with a cool one.
  • If your roof is in poor condition or near the end of its life, it is usually best to re-cover, replace, or retrofit the roof.

A cool roof does not necessarily cost more than a non-cool roof, especially if you are installing a new roof or replacing an existing one. However, converting a standard roof that’s in good condition into a cool roof can be expensive. Major roof costs include upfront installation (materials and labor) and ongoing maintenance (repair, recoating, and cleaning). Additional cool roof costs include specialized materials and labor.

Cool roofs can save money several ways, including energy savings, rebates and incentives, HVAC equipment downsizing, and extended roof lifetime. One way to estimate how much energy you would save by installing a cool roof is by using the Cool Roof Calculator.

  • Areas of application
  • New and Existing Commercial Buildings
  • Maintenance Facilities
  • Non-HVAC structures
  • Storage Facilities and Hangers
  • Schools and Universities
  • Multi-Family Housing
  • Mobile Homes and Offices


Your climate is an important consideration when deciding whether to install a cool roof. Cool roofs achieve the greatest cooling savings in hot climates but can increase energy costs in colder climates due to reduced beneficial wintertime heat gains.

In warm, moist locations, cool roof surfaces can be more susceptible to algae or mold growth than hot roofs. Some roof coatings include special chemicals that prevent mold or algae growth for a few years. In cold climates, roofs can accumulate moisture through condensation, and it is possible that cool roofs might be more susceptible to accumulating moisture than dark roofs of the same design. Condensation can be avoi-ded using proper design techniques.
