Conservation is among the best ways to lower a high energy bill due to increased room heat which requires the air conditioner to run continually. High temperature ranges and rising humidity are both large contributors to escalating energy intake.

One method to decrease such costs is to switch providers when this type of change is allowed; another method is to replace old equipment with energy-efficient ones. This could help that bill somewhat; nevertheless the real culprit is appropriate overhead – the roof! Yes, if there is a negative roofing system on the home, it really is probably causing increased bills.

Assistance from Technology

The solution to achieving an green and cost-efficient home is getting the right roof. From an energy-saving point of view, technology dealing with this part of a house has not shown much improvement until very recent years when some significant findings resulted in some promising changes, i just.e. the expansion of an energy-efficient roofing program. Following are some of the material types that have seen significant cost-saving developments.

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

Thangal 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 aluminium and is free from toxic lead. Metal types of coverings have the quality of solar reflectance thus absorbing fewer heat to go inside a home.

Clay and Slate – These supplies are environmentally friendly and are a great choice for an energy-efficient kind of covering. Clay and slate can be found in different designs, appearance and many elegant colors. They are perfect for roofs in warmer climates since they promote airflow on the surface which decreases ambient room temp and makes the house cool during the hot summer months.

Green Roofing – The roof of a house could be made entirely 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 more recently in German, an effective way to mitigate storm water run-off of. This covering includes a long service life, 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 possess a high ‘albedo’ (high solar reflectance) result. This is often applied to any type of roofing material. There are numerous types of coatings called ceramic, polyurethane and elastomeric coverings which are usually believed to give 80 percent solar reflectance. Additionally, there are coatings with excessive infrared emittance to radiate heat back into the atmosphere.
Color Choices

Colors for roofs have varying examples of solar reflectance. Whitened coatings reflect more of the ultraviolet sun to help make the home cooler. A gray coloring only has 25 percent solar reflectance; terra cotta possesses 41 pct solar reflectance; sunset rose has 43 per-cent solar reflectance; mocha has 36 percent solar reflectance; and cocoa/rustic dark brown own 35 percent solar reflectance. The initial cost is high; however, deciding on the best color will help save well on energy bills and will justify that initial expense. In addition, darker roofs retain more warmth which makes the home hotter and causes the air conditioner to work harder.


An excellent ceiling insulation can reap major benefits. Roofing insulation, also called radiant barriers, is installed to reduce cooling costs. It is made out of high reflective materials to decrease heat conductivity. Just like reflective coatings, the performance is based on emittance and reflectance plus the angle of installation. There are lots of types of radiant barriers and they all supply the same thermal insulation.
