Conservation is probably the best ways to lower a higher energy bill due to increased room heat which requires the air conditioner to run continually. High temps and rising humidity are usually both large contributors to escalating energy consumption.

One way to decrease such costs is to switch providers when such a change is allowed; another way is to replace old devices with energy-efficient ones. This may help that bill somewhat; nevertheless the real culprit is proper overhead – the roof! Yes, when there is a bad roofing system on the house, it is probably causing increased bills.

Assistance from Technology

The answer to achieving an green and cost-efficient home is getting the proper roof. Thangal From an energy-saving perspective, technology dealing with this part of a house have not shown much improvement until really recent times when some significant findings resulted in some promising changes, i just.e. the growth of an energy-efficient roofing system. Following are some of the material types that have seen significant cost-saving developments.

Asphalt Shingles – If the goal is to have a house look fabulous and become cost-efficient, recycled asphalt shingles may be the answer. ‘Cool’ shingles are increasingly being produced by manufacturers which are energy-star rated; come in a variety of colors; and carry a 40-year warranty with a potential lifespan of up to 50 years.

Metal – This may not be a consideration for each homeowner; however metal roofing is more energy-efficient when compared to asphalt shingles. It really is engineered from metal, copper, and aluminium and is free from toxic lead. Metal forms of coverings have the quality of solar reflectance thus absorbing fewer heat to go inside a home.

Clay and Slate – These components are green and are a good choice for an energy-efficient kind of covering. Clay and slate can be found in different designs, appearance and many elegant colors. They are ideal for roofs in warmer climates since they promote airflow at first glance which decreases ambient room temperatures and makes the home cool during the hot summer season.

Green Roofing – The roof structure of a house could be made totally of sod. Although an extremely old technique, the brand new version offers a wonderful layer of insulation over the rooms below. It is extremely effective in lowering energy consumption, appealing to the eye, and much more recently in German, an effective way to mitigate storm water run-away. This covering has a long service lifetime, decreases utility costs with the correct insulation, and helps absorb water during heavy rains.

Reflective coatings – Another breakthrough in the market is the expansion of reflective coatings. Reflective coatings include a higher ‘albedo’ (high solar reflectance) effect. This is often applied to any sort of roofing material. There are many types of coatings named ceramic, polyurethane and elastomeric coverings which happen to be believed to provide 80 percent solar reflectance. There are also coatings with great infrared emittance to radiate warmth back into the atmosphere.
Color Choices

Hues for roofs have varying degrees of solar reflectance. Bright white coatings reflect additional of the ultraviolet rays of the sun to help make the home cooler. A gray coloring only has 25 percent solar reflectance; terra cotta has 41 per-cent solar reflectance; sunset rose has 43 pct solar reflectance; mocha has 36 per-cent solar reflectance; and cocoa/rustic brown possess 35 percent solar reflectance. The initial cost is high; however, deciding on the best color will help save well on energy bills and can justify that initial expense. Furthermore, darker roofs retain more heat which makes the house hotter and causes the air conditioner to work harder.


An excellent ceiling insulation can reap big benefits. Roofing insulation, also known as radiant barriers, is installed to lessen cooling costs. It is made out of high reflective materials to diminish heat conductivity. Just like reflective coatings, the performance is founded on emittance and reflectance in addition to the angle of installation. There are several types of radiant barriers plus they all provide the same thermal insulation.
