Do Solar Panels Hurt Your Roof?

So, when solar panels are put, do they harm your roof? As long as your solar panels are properly installed, they shouldn’t cause any damage to the exterior or infrastructure of your roof for most homes. Solar panels will not harm the integrity of your roof provided you deal with a certified licensed contractor and your roof is in good shape.

When solar panels are installed, the technicians will drill holes in the roof to secure the panels. These huge holes are for lag bolts, which are strong enough to keep solar panels in place while also being weather resistant.

While knowing that a contractor is drilling holes in the outside layer of your home may give you the creeps, this is all part of the process of mounting solar panels so that they are completely secure and won’t cause damage.

To protect your roof, the lag bolts are covered with flashing after the panels are installed. A thin roll of moisture-resistant metal or plastic called flashing is used to help block off this hole and keep moisture, wind, and the weather out. It diverts water away from the area, so you don’t have to worry about moisture seeping into your roof from solar panels.

Many homeowners are hesitant to install solar panels because they are concerned about the roof’s integrity. What if the roof needs to be replaced or repaired only a few years after the solar panels have been installed? If this occurs, the panels will need to be removed, the roof repaired, and the panels reinstated, increasing the expense of repairing or replacing a roof.

Is it true that solar panels cause roof leaks?

The firm that installed the solar panels is a common reason for a roof to leak. Although most solar firms work hard to avoid leaks, others do not employ sub-roofing materials. Another cause of unintended roof damage is inexperienced sub-contractors.

If you find a leak soon after the job is finished, contact your solar panel company right away. The majority of solar firms provide guarantees on the solar panels themselves, but only limited warranties on the installation costs.

What are the disadvantages of having solar panels installed on your roof?

Solar power is ineffective at night.

Some solar enthusiasts may ask if they can live fully off the grid by adopting solar. In most solar technology applications, this isn’t feasible. While numerous solar businesses, including SunPower, provide home battery storage systems, most homeowners have only lately been able to purchase them. Solar energy is generally consumed in real time, with any excess sent back to the utility grid or stored in a battery. In the evenings and other times when sunlight is scarce, solar homes must rely on utility grids or battery storage for power.

Solar panels are unsightly.

The now-obsolete panels with enormous silver frames that sat high off the roof epitomized this. Solar panels today are streamlined, with significantly more simple designs that lay flush with roof surfaces, merge with diverse roof types, or even completely replace an existing root. Different color options allow homeowners to create systems that complement their houses’ appearance while yet producing the same clean, powerful energy.

Furthermore, homeowners with enough roof space or many portions of roof with adequate sunshine exposure may be able to design and install systems that aren’t visible from the street.

It’s also worth remembering that familiarity has a big impact on our impression of “attractiveness” at first. Most people don’t think garage doors are attractive, yet we’re so used to seeing them that we don’t notice them when we’re appreciating a home’s beauty. The same thing is happening with solar. As more solar panels are installed on homes across the United States, our impressions of how they affect the overall appearance of a property are shifting as well.

Thanks to advancements like SunPower Equinox home solar systems and InvisiMount racking, which have a minimalist design and eliminate superfluous hardware and utility boxes on exterior walls, some solar panels are now sleek, tiny, and fit snuggly against the roof. The inverter box is hidden behind each panel, making your system look more elegant while also increasing the amount of power it can generate. The panels appear to hover above the roof thanks to SunPower’s unique InvisiMount structure, which is practically invisible. SunPower Signature solid black solar panels are also available, which have a distinctly attractive appearance.

A home solar system is not something you can do on your own.

A residential solar system can be installed by expert DIYers, but most homeowners will need to hire a professional solar installation. While some DIYers may see not being able to install solar as a negative, for most homes, hiring professionals to handle the planning and technology to go solar simplifies what may otherwise be a complicated process. (For further information, see this Five-Step Guide.)

There’s also the issue of warranty coverage to consider. Most solar panel warranties exclude faults caused by shoddy installation by a third party. Furthermore, even if a DIY installation isn’t the source of a defect, consumers may be charged additional warranty fees for the removal of damaged panels and the reinstallation of replacement panels that weren’t installed by a qualified installer.

SunPower dealers are familiar with local permitting requirements, so they can help make the solar installation process go as smoothly as possible. Of course, the wiring must be handled by someone with electrical competence. You can schedule a free consultation to learn more about what it will take to convert your home to solar power. Professional solar installers have extensive experience designing solar systems for houses, ensuring that the system absorbs the maximum amount of available sunshine and saves you the most money on your electricity bill.

My roof isn’t suitable for solar panels.

Solar panels will not function on every structure due to shadowing and roof orientation. It helps to have a lot of sun-facing roof space to get the most out of your solar system.

Solar firms are used to dealing with a variety of roof kinds and styles, and often offer free consultations to help you figure out how a solar system will work best for you. SunPower solar panels are the most efficient on the market, which means you’ll need fewer of them on your roof. In other words, you can generate more energy in a less place. SunPower panels are also more efficient in low-light settings, such as shading, so even if your roof isn’t completely exposed to the sun, your system will still generate electricity. Because the SunPower inverters are situated behind each panel, if one is shaded, the others will be able to compensate.

Solar energy is harmful to the environment.

Solar panels are a produced product, and they have an environmental impact, just like any other building process, from the chemicals needed to make the panels to transportation and beyond.

Solar energy is one of the least polluting sources of electricity, and SunPower manufactures the most environmentally friendly solar panels today. SunPower’s “Beneficial by Design” philosophy, which seeks to be a regenerative force on the environment and society, elevates the bar for environmental and social sustainability.

Is there a disadvantage to using solar panels?

  • Before making a decision, homeowners should weigh the benefits and drawbacks of solar panels.
  • Electric bill reductions, a high return on investment, energy independence, and environmental friendliness are just a few of the benefits of solar panel installation.
  • Solar panels have some drawbacks, such as large upfront prices, the need for a lot of space, and the fact that you can’t take them with you if you move.
  • Overall, solar panels are an excellent investment for homes.

Is it true that solar panels void your roof’s warranty?

Fortunately, the answer is no. Unless you have a metal roof, drilling into the roof deck to attach the bolts for the solar panels will void your roofing warranty. It shouldn’t be an issue if your solar panels are correctly installed, mounted, and weatherproofed. Just make sure to study up on your roofing warranty before going solar, and communicate with your roofing and solar contractors to ensure that any roof penetrations or shingle removal do not void the guarantee.

When it comes to solar panels, how prevalent are roof leaks?

Roof leaks as a result of solar panels are relatively uncommon. When roof leaking occurs after the solar panels are installed, it usually occurs relatively rapidly after the installation procedure is completed. When it starts to rain or snow, almost all homes will discover the leak within the first year.

Is it necessary for me to clean my solar panels on a regular basis?

Cleaning solar panels every 6 months to a year is generally recommended to keep the panels’ productivity, efficiency, and effectiveness. Cleaning may be required more frequently depending on where you live and the degree of grime and pollutants.

Maintain Your New Solar System with Green Convergence!

A solar power system from SunPower is a fantastic investment. With SunPower’s 25-year warranty, you won’t have to worry about ongoing maintenance once you start saving money with solar, however we do recommend keeping your panels clean over time to get the most out of them. Investment in a house comes with certain maintenance charges, as does investing in a car, and investing in a solar system comes with specific polishing operations.


The cost of purchasing a solar system is relatively expensive at first. Solar panels, inverters, batteries, wiring, and installation are all included in this cost. Nonetheless, because solar technology is continually improving, it’s realistic to predict that prices will continue to fall in the future.


Although solar energy can be collected during overcast and rainy days, the solar system’s efficiency is reduced. Solar panels must be exposed to sunlight in order to collect solar energy. As a result, a couple of overcast, rainy days can have a significant impact on the energy system. It’s also important to remember that solar energy cannot be collected at night.

Thermodynamic panels, on the other hand, are an option to consider if you need your water heating solution to work at night or during the winter.

Check out our video for a breakdown of how effective solar panels are in the winter:

What are the top ten drawbacks of solar energy?

Solar Panels Have 10 Drawbacks

  • The initial investment is quite high.
  • The size of the system is determined by the amount of space available.
  • It works well in sunny conditions.
  • Solar panel manufacturing has the potential to affect the environment.
  • Low rate of energy conversion.
  • It is not possible to utilize it at night.
  • Solar panels are fastened in place once they’ve been installed.

Does solar power raise the value of a home?

Solar panels and battery storage can improve the value of your property on the real estate market, according to savvy homeowners, potential buyers, and assessors.

Each installation and property has its own set of numbers. Recent studies reveal that each 1 kilowatt of solar panels added increases the resale value by $4,020 to $5,911. 1,2

A 5 kilowatt solar panel installation would add an average of $20,100 to the market value of a mid-sized U.S. home at $4,020 per kilowatt. In California, a tiny 3.1 kilowatt system would add an average of $18,324 to the value of a mid-sized property at $5,911 per kilowatt. 2 Homebuyers are willing to pay a significant sum for a home. In addition, the selling price of a solar property is typically 3.74 percent or more than comparable properties without solar. 3

The cost of a typical rooftop solar installation and battery is typically recouped in the sale price of a home. Additionally, homeowners that invest in solar are rewarded with lower energy bills and favorable tax advantages that can pay the cost of the system multiple times throughout the warranty period.

Buyers Appreciate Solar’s Added Value

When acquiring a home, buyers take into account monthly electric expenditures. As a result, when evaluating the long-term financial value of a property, they’re becoming more willing to pay a premium for a solar-ready home.

Installing solar panels is considered as an improvement, similar to renovating a kitchen, according to the National Renewable Energy Laboratory, and homebuyers throughout the country are prepared to pay a premium for the economic and environmental benefits of a solar home.


With decreased monthly electricity bills and tax advantages for new installations, homeowners can realistically expect to not only recoup their initial investment, but also to make a significant profit. If you invest in a solar energy system, you can expect to see a significant increase in the value of your home. It’s a sensible, environmentally friendly energy alternative that’s inspiring more Americans to go solar every day.

When it comes to solar panels, how long do they last?

Photovoltaic (PV) panels, commonly known as solar panels, are designed to last for more than 25 years. Many solar panels that were placed as early as the 1980s are still operating at full power. 1 Solar panels are not only incredibly dependable, but their lifespan has risen substantially in the previous 20 years. 2 Many solar manufacturers back their equipment with performance guarantees in their warranties, in addition to decades of successful performance. 1

Keep in mind that just because your solar panels are predicted to last a couple of decades doesn’t imply they’ll stop producing electricity. It simply implies that their energy production will be reduced by the amount that solar panel manufacturers believe is necessary to meet the energy needs of the ordinary American family.
