Be Thermal Efficient: Use Metal Roofs
July 6th, 2010 by Theo
Do you have a very expensive electric bill? Have you ever planned to cut this cost by reducing your air-condition usage, but you just cannot do so because of the burning temperature inside your house? Are you torn apart from which to choose and prioritize between electricity bill and house cooling? If you are, don’t be confused. The metal roofing system has gotten it all for you: minimizing your use of air-condition by reducing the high temperature in your house!
With a metal roof, you can enjoy the coolness that you want while being complacent about paying your energy debts. You may not realize it yet, but this type of roof might be the house construction material that you’ve been waiting for so long.
A metal roof is a system of roofing that is made from metal tiles. Unlike other materials, metals are more durable, lightweight, portable and energy-saving. Asphalt shingles may last for 20 years with religious maintenance, while metal roofs can even last for more than a hundred years without needing demanding repairs. Most roofs of this type are painted with colors and coatings that will ensure a cool temperature in your house.
How do metal roofing colors and coatings cool your house? It’s easy. Physics tells us that a shiny surface bounces back light coming from a source. Metal roofs redirect the light from the sun, thus keeping your house interior free from heavy rays. Asphalt roofs do not bounce back light; they even absorb the heat coming from the sun. Reflective metal roofs, on the other hand, reflect solar radiation. But painted and coated metal roofs do not merely reflect the light, they also re-emit the radiation that is absorbed and probably stored in your attic. A highly painted and granular-coated metal roof can re-emit 90 percent of the absorbed solar radiation. Moreover, roofs with highly-reflective coatings like Kynar can save you up to 30 percent on air-conditioning usage! Look at how efficient you could get!
On the other hand, installing a metal roof is costly, that is why this roofing system is more popular among commercial buildings than in residential construction. But if you scrutinize the situation and look on the long run, you’ll see that metal roofs are more cost-efficient since they do not require maintenance. The fact that they can last for a century actually says it all! It also lessens your energy cost and can even protect your family from heat-related sicknesses which other roofing systems might cause. So don’t hesitate anymore. Heighten your house’s heat efficiency by installing a cool metal roof system now.

If you own a cat, at a certain point in your life you’ve probably grown tired of repetitiously opening the door every time your pet wants to go inside or outside. Cats need to “feel” the world outside for various reasons. They are born hunters in the wild. Being confined is not their nature. They have to be mobile and they need to experience independence in the “outside realm” sometimes. If you do not allow cats to go out, it will have negative effects on them.
