How to Reduce the Risk of Leaks before and after a solar panel installation

You want to get solar panels installed on your roof, but one of the greatest concerns you have is the possibility of a leak on your roof after the installation of a solar panel.

Or you are a homeowner who has recently installed a solar panel system on your roof and is concerned about roof leaks.

In this article we explore the following:

  • Reasons why your roof may leak after a solar power installation.
  • What causes roof leaks on a tiled roof?
  • What causes roof leaks on a tin roof?
  • Ideas to prevent roof leaks from occurring.

 

While some aspects of the solar panel installation process can put your roof at risk of leakage, all these risks are very easy to alleviate provided the right steps are taken before and after the installation of a solar panel. Here are some reasons why your roof may leak after a solar power installation –

  • Improper installation of the solar panels can cause roof leaks which is why it is important to ensure your solar installation is done by a CEC licensed solar installer.
  • When solar panels are mounted onto the roof, holes need to be drilled for the bolts or screws that hold them in place. If these holes are not sealed correctly or are not sealed at all, rainwater can seep through and cause leaks.
  • Solar panels that are installed too tightly can also cause damage to the roofing material, leading to leaks.
  • The weight of the solar panels can cause stress on the roof, especially if the roof is already weakened or damaged.
  • If the solar panels are not installed at the correct angle, water can pool on top of them and potentially cause leaks.

In this article, we will share ways to reduce the risk of leaks, both before and after a solar panel installation.

What causes leaks on a tiled roof after a solar installation?

One of the processes that can cause leaks on a tiled roof after a solar installation is due to the damage caused during the grinding of the tiles in the installation process. Grinding of tiles during a solar installation refers to the process of grinding or cutting into roof tiles in order to make space for the mounting brackets that hold the solar panels in place. This is done to ensure that the solar panels are securely attached to the roof and do not become dislodged or damaged by wind, rain, or other weather events.

After grinding the tiles, the solar installer must seal any gaps or penetrations with a waterproof sealant to prevent leaks from occurring in the future. Proper sealing is essential to ensure that the roof remains water-tight and does not become damaged over time

What causes leaks on a tin roof after a solar installation?

A solar installation can cause leaks on a tin roof if proper installation procedures are not followed. Some common causes of leaks on a tin roof after a solar installation are:

  1. Improper sealing: When mounting brackets are attached to a tin roof, holes need to be drilled into the roof. If these holes are not properly sealed, water can seep in and cause leaks.
  2. Improper installation of the solar panels: If the solar panels are not installed correctly, they may not be level or may put undue stress on the roof. This can cause the tin roof to become damaged and develop leaks.
  3. Loose hardware: If the bolts or screws that hold the solar panels in place become loose, the panels can shift and cause damage to the tin roof, leading to leaks.
  4. Damage to the roof during installation: If the roof is not properly inspected before the solar installation, existing damage to the roof may be exacerbated during the installation process. This can cause leaks to develop over time.

To prevent leaks on a tin roof after a solar installation, it is important to hire a qualified installer who is accredited by the CEC and is experienced in working with tin roofs and can ensure that proper installation procedures are followed.

Here are a few ideas to prevent water leaks from occurring:

  • Hire professionals to do the job

The installation of solar panels is too complicated a job to ever be taken on as a DIY project. Or be left in the hands of unqualified or inexperienced people.

The first step as part of your solar risk assessment should be to get a certified professional or company to do the job for you. This is encouraged because they will be able to evaluate your roof, point out any potential problems as well as draw a plan of action for fitting the panels in a manner that won’t adversely affect the existing structural limitations of your home.

 

 

  • Ask for references

The next step in your search for a professional person or company would be to verify them. Before committing your roof, home and money, ensure that the company is reliable with a proven track record of excellent and hassle-free service.

One way to do this would be by asking them for their license and other certifications. Searching online for reviews is another help. You can also ask them to provide references from the people they’ve worked for in the past. This simple cautionary step just might save you a lot of heartache and loss of money in the long run.

  • Keep the holes sealed

Since holes are drilled into the roof in the process of installing a solar panel, any type of such penetration is likely to make room for leakages. Make sure a layer of industrial-grade sealant is applied around the hardware. This will keep the hole sealed with no room for water to pass through.

  • Consider using add-ons

Add-ons such as commercial grade deflecting brackets are a great way to aid with water runoff. Consider using these and many other alternatives available in the market to minimize the contact of water from your roof and the panels installed on it.

 

 

  • Clean it regularly

Regular inspection of your solar panels and roof gives you the opportunity for immediate action in case a leak does occur. This will help reduce the damage that can be caused by the leakage.

In conclusion:

While there have been cases of water damage and leaking of roofs after the installation of solar panels, this doesn’t have to be the case with you. Carrying out due diligence of the contractors or the company that you choose to have your solar panels installed by will go a long way in ensuring roof leakage. Making the above-mentioned changes or additions can also prevent these water leakages from occurring and causing damage to your roof.

Sometimes, even if you take all the necessary precautions, something may go wrong. Therefore, it is highly advised to ask for details about the company’s or professional’s workmanship warranty and whether that warranty will cover possible roof damage in the future.
