50- to 60-Year Life Span
When installed properly, a metal roof can last 50 years or longer, where asphalt roofing, on the other hand, typically needs to be replaced every 15 to 20 years. So, even though a metal roof will cost more than asphalt shingles initially, the homeowner will actually end up saving money in the long run. It is also important to note that many metal roofing products are offered with lifetime warranties of 30- to 50-plus years.
Solid Wood Purlins
The Benefits of Installing Purlins for Metal Roofs
Metal roofing is a great option for your home that can bring a modern look and increase energy efficiency. It's cost-effective and one of the most environmentally friendly options. However, they'll need some kind of support structure to keep from bending or warping over time. Of course, one of the main benefits of using purlins is if you have existing shingles on your roof, and you want to install metal roofing over top of existing shingles, the use of purlins installed on top of the existing shingles has several advantages.
One way to support a metal roof is with wood purlins. These function much like rafters, except that they stretch between each angled part of the roof rather than along it.
Here are some of the benefits of installing purlins in your next build.
The main reason to use something like wood purlins for your metal roofing is that they provide both support and stabilization.
If you were to install a roof without purlins, you'd have to build a deck for the roof. This can result in a lot of extra time and materials. Instead, purlins can be used much more easily, and they provide a unique appearance to your interior.
In addition, purlins tie the rafters together so they can withstand heavier winds and weather conditions. You don't have to worry about them flying off or sagging down.
Energy Efficiency
Studies conducted by the Cool Metal Roofing Coalition and the Oak Ridge National Laboratory show that energy-efficient metal roofing materials coated with Energy Star-certified high reflectance paint systems can save homeowners up to 40 percent on cooling costs compared to asphalt shingles. A typical shingle roof absorbs most of the sun’s energy, making the attic extremely hot in the warmer months. On the contrary, Energy Star-certified metal roofs reflect a high percentage of the sun’s energy back into the atmosphere, which lowers attic temperatures and makes the roof more energy-efficient. In order to meet Energy Star criteria for roofing, the metal roof needs to have a total solar energy reflectance of at least 25 percent. Lighter metal roof colors have better reflectivity. For example, the reflectivity of a white metal roof exceeds 60 percent.
