Everything You Should Know About Metal Roof Installation

Metal roofs are the pinnacle of roofing systems. If you’re looking for lifetime longevity and minimal maintenance, a standing seam metal roof might be the best choice for you. Metal roofs reflect heat away from your home and save energy. They have an energy efficiency ratio of around 50% with the proper underlayment, are considerably cooler to the touch than asphalt roofs, and last far longer.

How does metal roofing conserve energy?

The easiest way to think about metal roofing and the enormous benefits it offers when it comes to energy conservation is to imagine holding a mirror on a bright, sunny day. You will notice how the glass reflects the heat and energy into the air – the same thing happens with a metal roof. In fact, according to this survey conducted by the Florida Solar Energy Center, a white or light-colored metal surface offers about 67 percent reflectivity. In contrast, dark asphalt shingles have a lower reflectivity (around 22 percent), and release the heat into the structure beneath them, making your home warmer. Standing seam metal roof systems have the highest rated integration level with all solar PV systems.

Energy vs. Aesthetics

One complaint some people have against metal roof installation on their home is the look of it. However, metal roofing is now available with fitted whole-panel to single shingle-like designs, offering customers a wider choice in achieving the look they’re going for. Some metal roofing is also formed from steel, aluminum, or even copper and stainless steel, making the aesthetic perfect for many styles of commercial and residential buildings.

Putting metal roofing over asphalt shingles

Another great thing about metal or steel roofing is that you can potentially avoiding tearing off old asphalt shingles to place metal roofing over the top of them. This will depend on building department roofing codes where you live, but in many cases, as long as your roof has no more than two layers of asphalt shingles, metal roofing can be placed over the top of them. This allows you to achieve an entirely different look for your house without the additional costs involved in tearing off the old roofing materials.

Keep in mind that if you’re installing metal roofing over asphalt shingles, it’s best to use a steel shingle system instead of the standing seam steel. The reason for this is that the latter, long, single panels that run vertically are used, and are placed from the eave to the ridge. Steel shingles, on the other hand, are installed in horizontal rows, just like other shingles.

Installing a metal roof

As with any total roof replacement or repair, installing a metal roof is a massive investment, but one that should last for at least 20 to 30 years, depending on the quality of installation and the type of metal roof you’ve chosen. Placing careful emphasis on how much you want to spend and the investment you’ll be making on adding value to your home is a must when installing a metal roof!
