Unfortunately, the luxury of having access to online temperature converter is not always feasible. You can learn how to easily convert the temperature by using a simple formula.  We will also cover a modified / simplified formula that is easy to remember.

Thus, if you would like to convert 80°Fahrenheit to the temperature in degrees Celsius, you’ll have to use the following formula:

(° F – 32) / 1.8. For instance, (80° F – 32) / 1.8 = ° C

48 / 1.8 = ° C = 26.6° C

You can actually simplify this temperature conversion formula by replacing 1.8 with 2. Of course, your results will be slightly different, but only slightly. This is a convenient approximation and gives you a ball park conversion of temperature. For instance, by going back to the example above, you will find that

48 / 2 = 24° C , which is pretty close to 26.6 degree Celsius.

So just remember to subtract 32 and divide the results by two to get an approximate result in the temperature of different scale.

If you would like to convert a temperature in degree Celsius back into Fahrenheit, then just reverse the order. For instance if you would like to convert 31° Celsius in Paris to approximate temperature in degrees Fahrenheit, you would, then 31 times 2, and add 32.

You will get 31 X 2 + 32 = 96 degrees Fahrenheit. This is approximated result of temperature conversion done using simplified formula of multiplying by two and adding 32.

The more precise results would be slightly less than 96° F, because we would multiply 31 by 1.8 instead of 2, which would give us;

55.8 + 32 = 87.8 Vs. approximated 31 * 2 + 32 = 96
Hopefully this simplified way of converting temperature will help you to perform quick, and relatively precise conversions from one scale to another, wherever you are.

So, your old asphalt shingles roof is leaking again and you want to find a good replacement that won’t leave you drenched from roof leaks. Metal roofing is a green roof alternative that is energy efficient, environmentally safe, and can last for well over half a century.

Unfortunately, and all too often, our good old cheap asphalt roofs fails on us when we least expect it! And we used to think that, it could never happen to us… I have been in those shoes myself!

Let’s face it, a roof that is leaking is not a kind or problem that can be ignored. A leaky roof could cause thousands of dollars worth of damage to your home, and the sooner you take care of your roofing problem, the better off you will be. I know this is not the most exciting moment of your life, but you will have to make some decisions as to what roofing materials you will choose for your house. There are many different roofing options available, and I am going to suggest that asphalt roof is not the option you will want to pick, because they are becoming obsolete. Yes, I said obsolete!

Like it or not, but we live in the 21st century and it seems as though the good old cheap asphalt roof no longer cuts it. Unless, of course, you plan to sell your house in a few years and move out so that the new owner will get stock with the inferior roof. It is estimated that an average lifespan of an asphalt shingle roof is only 15 years. Add a few years in a temperate / good climate, and subtract a few years for Northern and extreme Southern climate such as Florida, Arizona, and Texas. This is not a very lucrative option to know that your roof is bound to fail and you will have to spend your money re roofing your home all over again. So what is the solution you will ask…

In the last decade, there has been a quite sizable increase in the popularity of metal roofing installations, and I am not talking about the old barn style naked roof that makes the rain drops sound like a machine gun rattle. No, that is not the case, and in fact, modern metal roofing choices have become very sophisticated. They come in a variety of metal roofing colors from white snow to Vermont slate blue, and shapes that will blow your mind. For example, there are metal roofs that look just like wooden shake with unique texture and coloring. If you like the look of slate roofing, then you can get a metal roof that looks like slates.

Whatever your style and color preferences are, metal roofing seems to provide a solution to satisfy those unique needs and desires, from red Spanish tile – stone coated steel roof, to  aluminum shakes reminiscent of traditional Cedar Shakes . But, here is the best part, unlike asphalt roofing that is bound to fail soon, quality metal roofing installations are known to last as long as 100 years. As for the material manufacturer warranty, many modern metal roofing products come with up to 50 years non-prorated warranty.

And by the way, metal roofing can save as much as 25% on the air-conditioning costs. If you choose a white colored, sun reflective metal roof, than your energy savings could be as high as 50%. And did I mention, there is also a 2010 $1500 tax credit available from the government if buy a metal roof.

Finally, as far as cost goes; metal roofing prices, may initially seem as high vs asphalt shingle roofing, but if you stay in your house long enough it will more than pay for itself. Best of luck with your roofing project.

One does not to be a hardcore environmentalist to see how detrimental asphalt shingles roofing products are to the nature and the environment. So, the big question comes up, what is an environmentally friendly and practical roofing alternative to an asphalt shingle roof? The answer is simple, for the last few years metal roofing has been gaining market share and popularity as a green roofing material of choice.

Metal roofing can last much longer than an asphalt shingle roof, which only averages 10 to 20 years of service life. Metal roofing on the other hand, can last well over 35 years when properly installed.
The key to a long lasting metal roof is strict adherence to the metal roofing manufacturers installation guidelines.

Metal Roofing Installation Video

Installing metal roofing correctly involves preparation of the roof deck, proper application of roofing underlayment, and correct installation of metal roofing system. Whether or not you hire a professional metal roofing contractor, or choose to go do it yourself way, be sure to follow the installation instructions thoroughly. This way your metal roof will last for decades providing energy savings, maintenance free roof protection, and durable and long lasting beauty.

Here are a few reasons to consider metal roofing for your home

Metal roofing is reliable and long lasting green building material, which means that you can earn green building credits for the installation of the energy efficient metal roof that is rated by Cool-Roof council and by Energy Star for its solar reflective properties.

Metal roofing can help lower your homeowner’s insurance by as much as 35%. Metal roofs are fire retardant, which means they do not support fire, which can be a significant factor if you live in a heavily wooded area. Metal roofs can withstand powerful storms and category four hurricane winds. This may be very helpful if you live in a hurricane prone area.

Metal roofs provide excellent protection in the cold climates. Coated with specialty coatings, metal roofs shed snow and ice, which may help you prevent ice dams from forming on your roof.

As far as aesthetics go, modern metal roofs may add a unique touch of modern architecture to your home. You can choose from than traditional metal shingles and shakes profiles available in beautiful metal roofing colors, to the vertically oriented lines of standing-seam metal roofing panels that can easily be enhanced with roof integrated solar roofing panels. This combination will make your house not only energy efficient, but also capable of generating electricity from the sun.

Do not let the initially higher metal roofing costs to deter you from considering installing metal roofing for your home. Metal roofing will help you lower your cooling costs, appraise the value of your property, and provide many years of reliable and worry free service to you.

My point of contention is that we can combine the economic prosperity with the betterment of our environment?

I am going to illustrate my point with two examples that are very concurrent and relevant to understanding the current state of affairs in the U.S and learning from the mistakes of the not so distant past.

Death of the electric vehicle or GM kills the electric vehicle… Why?

Whose fault was it that GM was to busy worrying about the price of its stock, and making money by producing fuel hungry cars and SUVs, and suing the state of California, while Toyota and Honda were developing energy efficient hybrids vehicles.

And what happened when the electric vehicle program, although expensive at the time proved to be a success? What did GM do? They decided to kill the electric vehicle program altogether, although there were many people willing to buy those electric cars in the state of California. That was wrong on the part of GM, and displays a clear lock of corporate social responsibility. Not to mention, their greed and obsession with price of the stock is responsible for the current state of affairs of auto-making industry in the U.S today. I am not even going to mention their current stock situation, and the governmental bailouts that we are paying for?

So what was it, excessive corporate greed, lack of foresight, or a little bit of both?

Now GM is losing all the money because of its greed and lack of foresight, in the past. Toyota and Honda on the other hand, are ripping the benefits for investing and building the hybrid vehicles. Toyota and Honda are making money, but also helping the environment by propagating the idea of clean air, ultra low emissions, reduced carbon footprint, low fuel consumption and energy efficiency. It is a win win example of money working to better the environment.

Connection between crude oil, environment and our roofs.

It is not just about ultra low emission cars. In fact, it is about something as mundane as residential building materials that go into the houses we live in. For instance, asphalt shingle roofs are petroleum based products that are heavily marketed by money hungry asphalt shingle roofing manufacturers. Asphalt shingle roof averages a lifespan of only 17 years, then comes the inevitable demise when it gets torn off and dumped into our landfills.

So what is the alternative you may ask, or is there any alternative? Yes there is, and it has been here all along!

Using the types of roofing materials that are environmentally friendly. Tamko a heavy weight asphalt shingle roofing manufacturer has made a switch by purchasing Metal Works metal shingles roofing manufacturer that makes Metal roofing that is an energy efficient and environmentally safe building material. Metal roofing is fully recyclable, and lasts three times as long as asphalt shingle roofs.

Certainteed roofing, another heavy weight of the roofing industry, on the other hand keeps pushing its line of asphalt shingle roofing products despite the fact that they are bad for the environment. And who is there to rebuke them? Who is doing public education and spreading sustainable building awareness?

The U.S green building council is the responsible body for promoting green building practices, but how come their scope of influence so limited? Why do not we hear more about it? What about EPA, and Energy Star? Why are not they doing public education campaigns to influence the corporate giants? Somebody has to do it. A lot of it is about awareness, and PR pressures, so spread the awareness, do not buy asphalt shingle roofs, nor fuel hungry SUVs. Think green and act upon it!  Somebody’s quote comes to mind here… Yes we can! …. So can we?

As means for measuring temperatures, there are two separate scales that are used, which are called Celsius and Fahrenheit. These scales are named after their respective inventors. The Fahrenheit scale is the one that is mostly used in the US, while Celsius, which is a component of the metric system, is mostly used in Europe and the rest of the world. Both use a different scale to show temperatures, which we will illustrate with an example:

On the Fahrenheit scale, regular water reaches its boiling point at approximately 212 degrees, for which the equivalent in Celsius would be 100 degrees.

In order to convert Celsius degrees to Fahrenheit, and Fahrenheit to Celsius, some simple math is required, but this is easy to do, and anyone can do this, following a few simple steps.

There are only two steps involved for Fahrenheit to Celsius conversion:

1. Take the temperature in Fahrenheit and from this outcome 32 is subtracted
2. The outcome of step 1 is then multiplied by 0.55 (5 divided by 9)

For example, if in New York the temperature is 80 degrees Fahrenheit, the same temperature, when converted to Celsius would be 80 – 32 = 48 x 0.55 = 26

Celsius to Fahrenheit conversion:

1. Take the temperature in Celsius and multiply it with 0.55
2. Take the outcome of step 1 and add 32 to it.

For Example, if the temperature in Barcelona, Spain would be 21 degrees Celsius , the same temperature when converted to Fahrenheit would be 21 x 0.55= 11.5 + 32 = 43.5

As shown in the examples above it is quite simple to make temperature conversions from Fahrenheit to Celsius and vice-versa.

However, conditions may arise, when a fast result is needed, or when there is no calculator at hand. In such an event the use of an online temperature converter, may be just what you need, in order to quickly determine the temperature in Celsius or Fahrenheit. Temperature Converters are freely available on the Internet, and there are several web sites that provide them at no charge. Simply do a search on one of the popular search for the term “Temperature Converter” and you will have several free ones at your disposal.

When using an online temperature converter, all you have to do is fill out the measured temperature and select the proper scale. Clicking the submit button of the converter will immediately display the matching temperature on the scale desired.

While most English speaking countries still use the Fahrenheit scale for measuring temperature, the current trend is that more and more countries are switching over the Celsius system as a means to measure temperatures, which means that especially for residents of the United States and to a lesser extend the United Kingdom, conversions from Fahrenheit to Celsius and the other way around are becoming more and more common, which makes the ability to convert these temperatures a necessity, in order to be able to measure the correct temperature for both scales.

Fuel hungry cars, airplanes, and manufacturing plants are not the only CO 2 / carbon footprint contributors. Residential, commercial, and industrial buildings are also contributing a great deal to overall carbon footprint. Poorly insulated buildings consume vast amounts of energy, natural resources, and contribute to greenhouse gases affect. One of the ways to combat environmental degradation associated with poorly constructed buildings, is to use green building technology in retrofitting of existing buildings and constructing new buildings using green building practices.

Green building practices encourage environmental responsibility through the use of sustainable building materials in residential and commercial retrofit and new construction projects. The roof structure of the building is not an exception when it comes to in green building design. In fact, roof constructed according to green building practices can earn green building credits with the U.S. green building council based in Washington, DC.

Whole Foods Market place, one of the U.S. top organic food retailers has embraced green building technology by building a state of the art store made of aluminum and green building materials. The roof design incorporates vegetated roofing technology by using easy to integrate green roofing containers containing local vegetation. Green roofing design provides energy savings, insulation, and combats urban heat island affect.

In order for a roofing system to qualify for green building credits it must meet solar reflectivity index of a minimum of 78 percents for flat roofs and 29 percents for sloped roofs. Solar reflectivity index is assigned by cool-roof rating council. SRI incorporates solar reflectivity and thermal emissivity.

Metal roofs provide a wide variety of sustainable roofing options including standing-seam roofs made with long lasting and environmentally friendly metals such as aluminum, zinc, steel and copper. Metal roofs contain up to 50% post consumer content and are fully recyclable. Painted metal roofing panels are coated with solar reflective paint finishes that help keep the roof cooler in warm seasons.

The use of metal in a residential, commercial and industrial roofing aides in reducing building’s carbon footprint, and provides long lasting and reliable roofing solution that is also U.S green building council accredited.

In a typical residential re-roofing situation, the cool-roof rated galvanized steel metal roofing system can offer longevity, durability, energy savings, and earn green building credits for existing buildings and new construction. Modern steel shingle metal roofing systems are available in wide variety of cool-roof rated metal roofing colors that literally reflect solar radiant heat, reduce air conditioning load and provide energy savings.

For homeowners whose roof is covered with a flat roof, installing PVC based cool flat roof membrane similar to IB roofs in performance will provide significant energy savings, reliability, and long lasting roofing solution. Yes, PVC and green combination may seem counter intuitive, but PVC roofs can last three times longer than EPDM Rubber roofs and can be recycled when the roof has served its purpose. Certain PVC roofing systems are designed to withstand standing / ponds of water, which means that they can be used for vegetated green roofing systems.

No matter what type of metal / cool roofing system you choose, be sure to pay special attention to longevity and Cool Roof ratings of the roofing system in question.
