Why You Should Put Solar Panels on Your Metal Roof
Going solar with a metal roof could prove to be the most optimal situation for your solar power system. Meaning, your initial investment performs better than you could have ever imagined. Metal roofs are said to be the best type of roof for solar panel installation due to lifespan and durability of the roof, the ease of installation, and lastly structural and environmental/energy benefits.
Metal roofs are light and durable which is why many homes and businesses leverage it as an option for their space. Before installing solar panels be sure to understand the remaining life expectancy of your metal roof. Most metal roofs can outlast solar power systems by two times. The typical lifespan of solar power systems is averaged at 25-30 years and a typical lifespan of a metal roof is averaged at over 60 years.
Not to mention, metal roofs offer the durability typical roofing products can’t. It is less likely that your space will develop a roof leak when you have a metal roof. Damaged roofs require the expense in repair as well as the added expense that comes with removing and reinstalling the solar panels. In addition to those out-of- expenses, there is the additional (soft) expense or loss that is due to the number of days power wasn’t able to be stored for use.
Ease of Installation:
When it comes to installing solar panels on your roof, typically, an installer will drill holes into the roof so that they can attach the mounting for the solar panels. This is a serious cause for concern as improperly mounted systems can cause a leak and other roofing issues. For this reason, a standing seam metal roof is the best situation for installation because your installer can use a mounting clamp system that doesn’t put holes into your roof. As an added bonus, this can speed up installation times (and lower your labor costs) because your installer won’t have to drill any holes into the roof.
One caveat is a corrugated metal roof, this system might require some holes to be drilled. However, there are unique solutions for installation with this roofing type. It just means that waterproofing should be an important discussion point with your installer.
There are additional benefits to a metal roof and solar panel duo for your home or office:
- Structure Support: With a metal roof, there isn’t as much work needed to strengthen the building in order to support the additional load of the solar panels. That does not mean that reinforcement isn’t needed at all, just that it likely isn’t as intense as what an asphalt roof would require. However, roofing (both on conventional and metal) must always have the proper fastening so it can be reinforced with solar in mind.
- Energy Efficiency: They whole point of solar panels is energy efficiency, right? Good news, the combination of solar panels with a metal roof actually can increase the cooling benefits of your metal roof. Metal roofs reflect more sunlight than traditional shingles do and some metal roofs even come coated with reflective paint to help keep your space cool. Installing solar panels on metal roofs with this paint coating helps to lower the energy needed to regulate indoor temperatures. As a result, the combination of metal roofs and solar panels can result in higher levels of energy efficiency and savings.
- Environmentally Friendly: Metal roofs and solar panels are the two best ways to make your space eco-friendly. Installing a cool metal roof can help earn points through programs like LEED and ENERGY STAR. Both programs also encourage solar power systems as viable options for environmental impact. Not to mention, metal roofs are manufactured from recycled materials and, both metal roofs and solar panels are recyclable at the end of their lifespan. Pairing a metal roof with a solar power solution will help promote environmental sustainability as you contribute to increased utilization of recycled materials which ultimately lowers pollution.
- Performance in Extreme Weather: Unlike other types of roofing, metal roofs perform exceptionally well in high-winds. Solar panels in high-wind areas should be fastened securely using brackets. The correct way to secure solar panels using brackets is to fix it through the highest point in the metal roofing. Such an arrangement ensures that the metal roof anchors the solar panels securely to gain maximum benefit from the metal roof’s resilience to high-winds.

Explore the Next Generation of Solar Roofing
In a world of steadily increasing energy costs, solar energy has never looked as attractive as today — it is undeniably less expensive than fossil fuel-generated power. While bulky solar panels have been the norm for solar-powered homes, more homeowners are turning to the growing selection of solar roofing options for a more attractive roof.
Although they’re effective at producing energy, solar panels have not always been very attractive. They can be heavy, bulky, and can lower your home’s curb appeal even while they’re lowering your energy costs. A sleeker alternative, solar roofing looks more like a traditional roof made of shingles, tiles, or metal panels. But just like solar panels, a solar roof harvests the sun’s energy to convert it into electricity you can use every day.
The main drawback of solar roofs right now is the cost. Compared to the average cost to replace a roof (14,000 for a 2,000 square-foot architectural shingles roof at 7-15 per square foot) and the cost to install solar panels (18,000 for a 6-kilowatt system installed on the roof) combined, solar roofs can be more costly.
In this article, we’ll look at the different types of solar roofing, their pros and cons, and the average cost to have them installed in 2021. Is a solar roof right for your home?
Solar shingles are one of the hottest buzzwords in the solar industry right now. These highly durable roofing shingles mimic the look of a shingle roof but are embedded with silicon solar crystals. This can ideally give you the best of both worlds; an attractive roof and decreased energy bills.
As of right now, there are four main brands of solar shingles: Tesla, CertainTeed, Luma, and SunTegra. Of these, CertainTeed is a roofing and building material manufacturer that has jumped into the solar energy game. The others began as solar companies, then branched into roofing. All these companies offer solar shingles that match the appearance of traditional asphalt shingles, concrete tiles, or shingles that have a look all their own with a sleek, black, flat appearance. The growing selection of designs means that you can have your solar cells and an attractive look that complements your home.
Advantages and Disadvantages
The most important advantage to using solar shingles is the enhanced curb appeal for your home after they are installed. Rather than large, heavy panels installed over your current roofing, a modern solar roof will look like, well, a roof. Without the panels mounted on your roof, you also don’t have to worry about leaks or roofing deterioration; solar shingles are surprisingly durable and long-lasting.
In most instances, it is recommended that you cover the entire roof with solar shingles in order to maximize your output and get the same amount of wattage as with solar panels. In some cases, it’s also possible to mix the solar shingles with other roofing materials. Depending on the manufacturer, you may need to use their non-solar shingles to create a match with the rest of the roof. For example, if you have an area that is perpetually in the shade, and you choose Tesla shingles, you will need to use Tesla’s non-solar shingles in the shady areas to match your solar shingles.
Solar shingles do have some drawbacks compared to traditional panels. Each solar shingle tends to produce less wattage than the same area of traditional panels. To equal the output of the standard 10 to 14 panels a house may need, you will need to cover your entire roof with solar shingles. On the other hand, mixing solar and non-solar shingles can provide flexibility. For example, if you want the shingles to power your garage only, you can just install them there. There may be a subtle difference in the appearance of the shingles on the two areas.
You’ll also need to make sure that your entire roof is free of debris, dirt, and snow to help keep power flowing optimally.
Costs will vary depending on the brand. For most solar shingles, expect to pay between 20 and 25 a square foot for most homes, around 45,000 for a 2,000 square-foot roof.
Metal Solar Roofing
Metal solar roofing is an alternative for those who want all-over solar roofing but don’t like the look or costs of shingles. A metal solar roof is essentially a standing seam roof with solar film inside the metal sections. Your roof will be nearly identical to any other standing seam metal roof — this is a roof made of metal panels with a connecting seam that sits above the panels themselves. They’ll have all the benefits of a metal roof, such as durability, but with the added bonus of solar technology as well.
Several companies make metal solar roofing, including INroof Solar and Roofit.solar. Because the solar technology is built into the roof, their roofs look identical to a regular standing seam metal roof.
Advantages and Disadvantages
Metal solar roofing comes with many of the same concerns as solar shingles. You must install them over your entire roof to get the same benefits. And you need to keep the entire roof free of snow, dirt, and debris. One advantage of the metal roofing, however, is that snow tends to slide right off, so you’re less likely to need to get out there and do it yourself. Metal solar roofing also looks like traditional standing seam roofing and is highly durable. It’s not likely to crack or dent in storms or with hailstones, so it can outlast traditional panels.
start around 12.75 a square foot for a metal solar roof, which is on the high end of a traditional metal roof, but lower than the cost of solar shingles. Your costs can vary by company and design, as well as by the total size of your roof; however, you can expect the cost of metal solar roofing to start around 25,000 for a 2,000 square-foot roof.
Interlocking Solar Roof Panels
After years of high costs, solar roof panels are now the least expensive and most efficient way to get solar energy to your home. But most people don’t like the racking system, which is both visible and can damage the roof below. Interlocking solar roof panels solve these issues. Essentially, these are solar panels that install right on your roof deck — no racking or roofing material beneath them. The edges of the panels interlock and are sealed to create one, smooth, complete surface. While these are more visible than solar shingles or metal panels, they’re less obvious than traditional solar panels. They can also potentially provide more wattage for the coverage, allowing you to go off-grid more easily.
As of right now, two companies are making this type of solar roofing: GAF and SunTegra. GAF is one of the oldest roofing manufacturers, which means that they understand the limitations of what can be placed on a roof deck. SunTegra, on the other hand, is better versed in solar technology and maximizing the output from each panel. Both can give you a sleek-looking roof without the metal racking system of traditional solar panels.
Advantages and Disadvantages
The biggest advantage of this system is its simplicity and efficiency. A traditional solar installation would start with a new roof, if you needed one, with the solar panels installed on top. But with this system, there’s no need to install a new roof because the panels are the roofing — there is no roof below the panels. As a result, the panels are less prominent than traditional solar panels, and concerns about heavy panels damaging the roof are virtually eliminated. This option also has the potential to produce higher watts than other types of solar roofing.
Depending on your aesthetics, one drawback with this system is that it will look like you covered your roof with solar panels. The panels are smooth and installed together over the entirety, but it does not look like any other roofing material currently in use today. Also, they can be more expensive than some other solar installations, particularly if you don’t need a new roof.
This option of solar roofing tends to be priced by the watt, much like traditional solar systems. But while a solar panel system installed on an existing roof may cost just under 3 a watt, these systems cost nearly 5 a watt, including the materials that may not be producing solar energy. This means that for a 2,000 square-foot home, you would pay between 30,000 and 35,000 for a 6,000- to 7,000-watt system.
Consider Solar Roofing
Solar panels and solar energy are getting a lot of attention with the rise of energy costs and climate change. Solar energy use in a home can even potentially increase a home’s value due to the savings it can bring. But panels aren’t the right fit for every home or installation. If you like the idea of solar energy, but not the idea of bulky panels on your roof, take a look at the different types of solar roofing available today to see if one of these might suit your needs better.

Find the Metal Roof Solar Mounting System that Best Suits Your Application.
There are multiple options when mounting solar on a metal roof, the details of which can impact installation costs and lifetime performance. Metal rooftop mounting consists of two basic parts: the (roof) mounting hardware and the actual solar panel attachment interface. Choosing to go with a rail-based or rail-less installation method depends on a variety of factors and is also a personal preference. S-5! offers attachment solutions for both methods.
Rail-free (direct-attach™) Solar PV Mounting
The PV module attachment and the roof attachment are a single assembly, so rails are not needed to provide a separate interface.
Rail-Based Solar PV Mounting
You can mount solar using rails that interface between the module attachments and the roof mounting attachments.
Balance of System (BOS)
Clamps, brackets, and interface hardware to attach service walkways, conduit, wire trays, optimizers, other module-level power electronics (MLPE), and monitoring equipment.
What Products Does S-5! Offer for Rail-Free Solar Applications?
The S-5-PVKIT is a rail-less mounting solution that uses the metal roof’s integrated “rails ” to attach solar modules. It reduces the weight of the mounting system, provides better load distribution and lowers overall material costs when compared to traditional rail mounting.
Save up to 35% on material cost and up to 50% installation time when mounting solar PV. Use your metal roof’s “built-in” rails and the PVKIT direct-attachment system. (Compatible with all S-5! clamps and most brackets.)
What Makes the S-5-PVKIT an Ideal Choice for Mounting PV on Metal Roofs?
Most metal roofs are uniquely different from other roof types. They give the roof covering structural capacity (beam strength), due to their longitudinal seams or rib configurations. As we like to say at S-5!, “ The seams (or ribs) of the roof are the rails!” The PVKIT attaches the modules directly to the seams or ribs of the roof without the need for the addition of rails. This leads to savings in material, equipment needs, shipping, logistics and install time. [link to content]
The PVKIT is mounted to S-5 clamps and brackets according to roof type. The distance from the roof surface to the back sheet of the module is approximately 4” or more, an ideal height for module cooling and performance.
Wire management is easier than you might think. In the words of our customers, “. it’s a piece of cake…”
When using the seams or ribs of the roof as rails, the modules are installed in landscape using the manufacturer’s prescribed mounting zones, which must be aligned with mounting locations.
The weight of PVKIT mounting is about 15% of rail mounting. Think of the savings in freight and logistics, not to mention added load to the roof structure!
The S-5-PVKIT is a great option for mounting to a metal roof. Just use the rails that are already there – they are free!

Why RAIKO ENERGY ROOF?
A sheet metal roofisup to 20 times lighter than other solutions. At the same time it is so durable that it doesn’t require any additional reinforcements. It is installed easily and quickly, minimizing the cost of a roofing work.
The use of roofing sheets and accessories is a profitable investment, influenced also by savings in construction of a foundation, walls, roof structure and the covering it self – with accessories and setup.
Shading a part of the mat doesn’t affect the efficiency of the entire installation. There is no need to install neither microinverters nor power optimizers as it is in case with standard modules. Up to 125W of clean energy can be produced on a single square meter of the roof!
Roof sheets can also be installed on old roofings with a weakened structure. The steel sheet is fully recyclable.
A well-mounted metal roofing providesan excellent protection from breaking during whirlwinds. Invisible connections between sheets prevents individual elements from tearing off.
