Almost every consumer knows that black socks or dark shirts will absorb more heat versus lighter colors. Since most people realize this basic concept I have trouble comprehending why 90% of the buildings in our nation have dark colored roofs. Putting a black roof on your home or building is not the smartest thing you could do.
It is common knowledge that colors affect us differently. White colors elevate us while dark colors depress us. Every morning when I get up I pull the curtains and let the light shine in. I want to be happy and feel good. When I poke my head outside to see what's going on in the world I like to see white color roofs versus their depressing counterparts. Are these dark colored roofs contributing to the epidemic of depression in our nation?
Roof heat transfer is the process of transferring the almost 200-degree roof temperatures into your attic. Attics can reach temperatures over 140 degrees. This heat creates moisture that falls to your attic floor on your insulation. This moisture causes your insulation to become less effective and this heat then sinks into your home. Insulation slows and prevents some of the heat transfer into your home but I can assure you it never stops this heat transfer. This heat then causes you're A/C unit to work. The hotter your roof gets, the harder and longer your air conditioning unit needs to run. The more your air-conditioning unit runs, the shorter it's lifespan becomes. Roof heat transfer is a term every American should become aware of.
A white roof will reflect 30% of solar heat gain versus a black roof. Some people claim that a dark roof is better in colder climates. Although I am still doing research in this area, I believe they could be wrong. I haven't found any studies yet that prove this theory.
Something every American should realize is that yes we have a shortage of oil, but we have even less natural gas. Years ago when oil wells were drilled it was common for oil producers to find gushers. Gushers were caused by the pressure from natural gas that pushed the oil to the surface. There is normally more oil than natural gas in every case. If no natural gas exists, oil producers have to install pumps to suck the oil out. You rarely hear of any large deposits of oil and almost never hear about gushers. When you hear about the shortage of oil, this should alarm you when you consider natural gas and your electric bill.
Most of our electric plants run on natural gas. It will take decades to build alternative power plants. Environmentalist don't want pollution causing coal plants built and most Americans are resistant to having a Chernobyl nuclear plant in their back yard. Since no other solutions are rapidly approaching, conservation is a necessity. We need to do everything we can to lower our consumption of electric power and natural gas.
Many people get very upset when the price of gasoline rises. Buildings use far more natural resources than our automobiles. If you conserve energy in your home it will have a direct effect on demand and prices for other petroleum products.
If you are the manager of a business that has buildings you are doing a great disservice to our nation and your company by installing a dark colored roof. Your job is to save your business money. The more money you make for your business, the more money you will make. Dark colored tar roofs are petroleum- based so you are contributing to our demand for foreign oil. It is not only unwise it is un-American.
If you are the Grand Pu Ba of a homeowner association that insists every home in the neighborhood has a dark colored roof to match, you need to alter your antiquated by-laws.
I like to think that environmentalist are leading the nation by example and informing others as well as themselves how to conserve our natural resources. They would gain a lot more credibility by doing so.
Anti-war protestors should realize the war revolves around oil. If you sincerely want this war to subside you should do your part to prevent our dependence on other nations. Chances are very high that WW III will arise over natural resources and the need of.
The lower gasoline prices are just temporary and will surely rise after the elections. People who believe they can complain and the government will force oil companies to lower prices are deluding themselves. The only way that could happen is if we threw out our present form of government and converted to a socialist country. We live in a capitalist society and supply and demand will dictate prices. Since there is an ever-increasing shortage of natural resources prices will continue to reach higher. Our only choice is to consume less and constantly search for alternative energy.
Conserving our natural resources is truly a matter of national security.

Post a CommentIt would be nice if this truly was the biggest mistake a homeowner could make, quite a verbose title for limited information.
I read this once in a fortune cookie.
Thank you for the info on the roofs, it is helping me on my science fair project. thanks
You have some facts screwed up. There are lots of Natural Gas reserves in this country, and coal is the biggest supplier of electricity, 57% worth.
Dale%2C my doctor doesn%27t think your roof-depression theory is correct%2C but I trust you. I%27m changing my roof right now. Doctor be damned%21 You%27re the man%2C Dale. You%27re the man.
The info I presented was from a scientific study from an authority on the subject. The white shingles may not make a big difference but it will offer some help and benefits. I have gotten some negative comments where people are more concerned with asthetics versus their electric bill. When their electric bill becomes more expensive then their mortgage they may think different. You can also cover your shingles with a water based primer and white elastomeric coating that contains ceramic microspheres. This will stop conductive heat from entering your home, prevent bulging landfills and you never have to roof your home again. Just reapply another coat every 10 years and it is something you can do yourself to save money. I'm going to do this on my home next year because I am far more concerned with cutting my electric bill, conserving the environment and reducing our dependence on foreign oil then I am with appearances. If you want and believe different, enjoy your dark shingles and high
It's the black in the asphalt that absorbs the heat.....simple stuff. Yes I white granule may be a bit cooler than a dark one...but the BLACK in the asphalt is what makes it hot.
You should check your facts, all shingles reach a tempature of 183 degrees, light colored roofs justs take a little longer to get there. This info is based off of GAF/Elk Shingles & Owens Corning. You might want to check into it further, because your web-site, made a homeowner pick a color that the did not like and now they have big regrets. It also looks like to me that your stating your opinion on a feelings that colors that make you feel. Most people who get black or dark color roofs because they have light color siding, and the standards are dark siding, light colored roof, light siding dark colored roof (although dark red & blue siding look great with bleck roofs) Also you should look into studies at U of MN, they built two buildings the same, side by side and used white color shingles and black color shingles on the buildings , and found that the dark color roof reached a temp on average of 98 degrees through out the summer and the white roof average 97 degrees.
Yes there are
what would you rather have a house that uses 15-20% more energy because you have to have a dark roof or when your looking at selling your house you go up and clean the roof off and show possible home buyers that they can afford the higher price your asking because each month their energy bills will be less.. I was going to sell my house, I got the possible sale price from several agents. they were all with in 2,000 dollars of each other
I spent 300.00 on an energy audit and 4,000 dollars on energy improvements that were suggested and my house was certified as an energy star home. I sold my house for $15,000 dollars more. the buyer was able to afford the larger mortgage because of the energy cost they would not occur each month..
On a dark roof, I would recommend installing a radiant barrier. It will "reflect" alot of the heat you mention in your article away from the attic insulaiton. You can easily do it yourself. www.atticfoil.com
