There are many ways in which you, as a homeowner, can save money on energy costs simply. One of which is by applying a heat reflective coating on your roof. Heat reflective coating has become more popular in recent years for a number of reasons, but you might have never heard of heat reflective coating, and might be curious about what it is, how much it costs, and how it can be a benefit to your home.
What is Heat Reflective Coating?
Heat Reflective Coating is a coating for roofs that is used to reduce the amount of heat absorbed by the roof by reflecting sunlight. Also known as cool roof coatings, these coatings are available in a variety of colors, materials and surfaces and ultimately make for a cooler living experience within the building or home. In sunny climates during summer, cool roofs can stay up to 60 degrees cooler than conventional roofing.
Coatings are ideal for structures that cannot have a full roof replacement, and work best on low-sloping roofs in good condition. Coatings are a thick paint-like substance and are typically sprayed on. The coatings will stick to a variety of materials including asphalt, capsheet, gravel and metal.
How Much Does It Cost?
Although every building will have different roofing needs, the Environmental Protection Agency says that new cool roofing can cost $0.75 to $1.50 per square foot, while cool liquid coatings — typically white or pale in color — run $0.60 to $0.80 per square foot,. There is typically a premium for cool roofs, ranging about 5 to 20 cents per square foot.
While the initial cost is more expensive than traditional roofing materials such as asphalt or aluminum coating, the long-term savings from the heat reflection roof or coating is greater. Additionally, federal energy tax credits may be available for existing buildings that have roofs replaced with heat reflective coating roofing.
How Long Does it Last?
When installed and applied properly, cool roof coatings can last as long as 20 years. Proper maintenance, such as washing particular types of roofs, can also extend the coating's lifetime.
What Are The Benefits?
Buildings with heat reflective coatings often see a reduction in energy costs. Because of the signification reduction of heat absorption, heat reflective coating provides for reduced energy usage, specifically with air conditioning and cooling in warm months. In addition, this reduction of energy also leads to reduced air pollution and greenhouse gas emissions. Cool coated roofs can also lead to better comfort for residents and workers, including a reduction in heath-related deaths.
How Do I Find The Right Heat Reflective Coating?
Coatings are available in two types cementitious, which contains cement particles, and elastomeric, which contains polymers to make the substance more flexible and adhesive. Elastomeric coatings provide additional waterproofing, so considering the roof's climate and environment is the first step to selecting the best, longest lasting coating. If you live in a rainy area, you will want to select a coating that can withstand constant moisture.
Builders and rehabbers will also want to consider the existing roof materials when choosing the right heat reflective roof coating, as not all materials are ideal for the coating's paint-like substance, and could have moisture issues. You will also likely want to find more info on a qualified professional in their area to install the coating correctly.
If you are looking for a simple way to update your roof, increase your home's energy efficiency, or looking for different options for a new roof heat reflective coating is a good choice. It is a simple, relatively inexpensive way to update your home.
