Conservation is among the best ways to lower a high energy bill due to increased room temperature which requires the air conditioning unit to run continually. High temps and rising humidity happen to be both large contributors to escalating energy consumption.

One way to decrease such costs would be to switch providers when this type of change is allowed; another approach is to replace old gadgets with energy-efficient ones. This could help that bill somewhat; nevertheless the real culprit is right overhead – the roof! Yes, when there is a negative roofing system on the house, it is probably causing increased bills.

Assistance from Technology

The solution to achieving an green and cost-efficient home gets the right roof. From an energy-saving point of view, technology dealing with this section of a house has not shown much improvement until pretty recent years when some significant findings resulted in some promising changes, my partner and i.e. the enhancement of an energy-efficient roofing technique. Following are some of the material types which 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 many different colors; and carry a 40-year warranty with a potential lifespan of up to 50 years.

Metal – It isn’t really a consideration for each homeowner; however metallic roofing is more energy-efficient in comparison with asphalt shingles. It is engineered from steel, copper, and aluminum and is clear of toxic lead. Metal types of coverings have the quality of solar reflectance thus absorbing much less heat to go inside a home.

Clay and Slate – These components are environmentally friendly and are a great choice for an energy-efficient kind of covering. Clay and slate come in different designs, appearance and several elegant colors. They are ideal for roofs in warmer climates because they promote airflow at first glance which decreases ambient room temp and makes the house cool during the hot summer months.

Green Roofing – The roofing of a house can be made completely of sod. Although a very old technique, the brand new version provides a wonderful layer of insulation over the rooms below. It is extremely effective in lowering energy usage, appealing to the eye, and much more recently in German, an effective way to mitigate storm water run-down. ceramic roof tile This covering includes a long service lifetime, decreases utility costs with the right insulation, and helps absorb water during heavy rains.

Reflective coatings – Another breakthrough in the market is the development of reflective coatings. Reflective coatings contain a high ‘albedo’ (high solar reflectance) effect. This can be applied to any type of roofing material. There are numerous types of coatings known as ceramic, polyurethane and elastomeric coverings which will be believed to supply 80 percent solar reflectance. There are also coatings with large infrared emittance to radiate warmth back into the atmosphere.
Color Choices

Shades for roofs have varying degrees of solar reflectance. Light coatings reflect additional of the ultraviolet rays of the sun to make the home cooler. A gray color only has 25 percent solar reflectance; terra cotta offers 41 pct solar reflectance; sunset rose has 43 percent solar reflectance; mocha has 36 pct solar reflectance; and cocoa/rustic brown include 35 percent solar reflectance. The original cost is high; however, choosing the right color will help save on energy bills and will justify that initial expense. Additionally, darker roofs retain more high temperature which makes the home hotter and causes the air conditioning equipment to work harder.


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