Does Installing Solar Panels Damage Your Roof

Will Your Roof Get Damaged From Solar Panels

Do Solar Panels Damage Your Roof?

Your roof wont get damaged as long as it is in good condition and can handle the weight of the panels. Fortunately, most of todays roofs can bear the added load of solar panels, and it wouldnt take your contractor long to install them.

There are a couple of factors you must consider before investing in solar roofing. One of them is the age of your existing roof. This part of your home naturally deteriorates as it ages. You must address any damage and get rid of the debris before having solar panels installed. Its also vital that your roof is the ideal size of the solar panels. You can make the most of your solar panels if they are facing west or south because they will receive a significant amount of sunlight.

Are Solar Panels Good For Your Roof

Many people worry about the damage their roof will suffer in the process of solar panel installations. But do they need to worry about the imaginary holes drilled into their roof?Brackets or solar shingles used to install solar panels, make the installation process effortless. Solar panels do not merely keep your electricity bill low, but they also come with some added benefits.

A cooler house

In addition to absorbing the suns rays, solar panels also reflect those rays and provide a break to thermal energy. The roofs covered by solar panels show an average drop of 5 degrees, keeping your cooling bill even lower.


Once installed, the solar panels dont require much maintenance. They equally protect your roof from different weather conditions, making it cost-effective and helping you save money on roof repairs. Since installation rarely needs drilling, one saves enough money on further restoration of the attic in case of water leaks. The panels act as a shield for the roof, reducing weather-related damages and increasing its life.

Do You Really Save Money With Solar Panels

Solar panels and solar panel systems will save you money and bring back your investment in an instant. Growing property value, reduced utility costs and a federal tax credit ease the cost of installing solar panels in advance.

How long does it take for solar panels to pay for themselves?

If you are at home all day, you will need less time to get your money back. You will reimburse the cost of installation on average between 11 and 13 years, depending on where you live. For comparison, if youre home only in the evening, its between 22 and 27 years old. This is all about how much electricity you consume.

Why is my electric bill so high with solar panels?

Solar energy systems are limited resources they can only produce as much energy according to the size of the system, and most utilities limit the size of the system to the historical average energy consumption on site.

Installation Procedures On Rooftop Pv Systems

There are two main types of installation procedures on rooftops for PV systems.

The first and most common for commercial applications is the ballasted footing mount system. This applies for commercial buildings or even some households that have a flat roof. This is the most ideal combination between roof and ground-mounted systems, because the PV system is able to combine the advantages of ground-mounted systems with those of rooftop systems.

Basically, it consists of pre-cast concrete blocks or steel structures anchored to the roof that can be placed on any position and angle. Generally, these flat roofs are made of concrete, so the engineers can ensure that the roof withstands the weight of the solar panels and the ballasted mounting system. You can take a look at an innovative flat roof mounting system design here.

Ballasted mounting system with concrete blocks

The second option, most common for residential US households is the sloped rooftop mounting. This option can be divided into several installation procedures:

Rail-Less Mounting Systems: This system does not use any rails to attach the modules to the sloped roof. Instead, it directly uses screws and bolts to attach the solar panels to the tiles. This type of system is less frequent now because it involves more penetrations to your roof, installation times are slow, and it can damage a tile by lifting it up with the force of the wind.

Does removing solar panels damage the roof? The process of removing the solar panel can be dangerous and cause damage to the roof if licensed professionals do not do it properly.

Weight Problems: Cracks And Collapse

Probably this is the number one concern when installing solar panels. Are the panels going to cause the roof to collapse or crack on the wall in the house?

Solar panels are not going to cause stability problems to the house in more than 90% of the cases, especially if we are talking about residential properties .

Solar panels are only a few centimeters thick and weigh an average of around 13kg/m2 . Each m2 provides approximately a peak power of 150W .

Hence, assuming an installation of 3kW, this implies you need 20 m2 of roof area for a total of 260kg . This is a lot of weight, but distributed over a large area it is not a problem for the majority of roofs.

Is your roof within this majority? Your installer must assess the property including also a deep check of your roof. If your property is not very old there are very high chances that it can withstand the solar panel weight.

However, even in the best conditions, your roof might be affected by drastic weather changes. Not talking about heavy snow but mainly sudden temperature variation. Are you experiencing cold freezing days followed by high temperatures within the next 24 hours? If so, consider reinforcing the roof.

Require Flashing In Wet Area

Conduit penetration flashing is becoming common practice for the majority of roofs with solar panels. Without getting into many details, these are kind of plastic or better metal covers, with a hole in the center where the cable passes through . Flashing is laid out either below or above the shingles and prevents water from getting in through a particular elevation of it.

Here my fourth tip.

To avoid roof damage due to solar panel installation ask the installer whether he is planning a conduit roof flashing for the cable. If the answer is negative, challenge the reason and ask for further explanations before signing any contract.

Why Your Roofs Age Matters

Do solar panels damage your roof? Do they protect it?

Just because you dont notice any damage at first glance at your roof, it doesnt mean that your roof is ready for a solar panel installation. The age of your roof can play a big role here too.

The lifespan of a roof depends on multiple factors including what it is made from, the climate and environment, and how well it has been maintained.

Many Florida roofs use clay tiles which have a long lifespan of almost 50 years. Shingled roofs often last for 15-20 years. If you live in a harsh climate your roof may have a shorter lifespan.

Why does this matter? Well, as the components of your roof age and wear out, they become vulnerable to cracking, holes, and leaking. An old roof will not be able to carry the added weight of heavy solar panels and might not hold up well when installing racking for your system.

If your roof is nearing the end of its lifespan, it is wise to replace it before installing solar panels.
