Roofs play the important role of keeping the elements out of your home, but it is easy to forget that UV rays are one of those elements that should be kept out of a home. Choosing a roof like an asphalt shingle roof will keep out the rain, but it will do nothing to prevent the UV rays of the sun from heating up your home. The more UV rays heat up your home, the more your air conditioner has to work to cool your home back down again. If you choose a roof based on its ability to keep your home cool rather than its ability to not strain your budget, you will end up saving more money in the long run.
An Analysis of Asphalt Shingles
Asphalt shingles are one of the most common types of roofing materials used in a home. The reason for their popularity is that they are also one of the least expensive roofing materials. While saving money is a worthy goal, trying to save money on the initial cost of a roof can cost you both on repair costs and on replacement costs. Asphalt shingles will only last 15–20 years. Other more energy-efficient options will last longer than asphalt shingles and will save you money on HVAC costs in the process.
The Energy-Efficiency of Metal
Galvanized steel roofs can last for sixty years. This is three to four times as many times as long as an asphalt-shingle roof. Thus, you can reduce your replacement costs by a third or even up to a fourth. Instead of absorbing heat like asphalt shingles do, metal will reflect the UV rays of the sun away from your home. By reflecting heat away from your home, metal can reduce your heating costs by up to 15%. While a metal roof will cost more initially, it will save you money over the long run.
The initial cost of a roof is not the cost you should focus on when you choose a roof for your home. Instead, you need to think about how the roof will protect your home for the long haul. Keeping out the rain is something that any properly installed roof can do. To really protect your home, you also need to look for a roof that keep out UV rays. Metal roofs are the way to go if you have a strong environmental conscience and/or if you like saving money. Talk to a roof contractor about your options.
