Issue- 1: Solar Panel Installation Error

Improper installation of solar panels can lead to various issues, including roof leaks. If the installer is certified or qualified, they may take shortcuts or need more experience to ensure a high-quality installation.

As a result, the roof’s protective layers may be damaged, inadequately sealed, or punctured.

How to Fix:

You can try these fixes to solve this issue:

• Make sure the solar panel installers you hire are certified and qualified.
• Consult reputable installers with a successful installation record to get competitive quotes.
• Overlook the cheapest option in favor of quality and expertise.
• Check the installer’s credentials and read customer reviews.
• Ensure the installer follows industry best practices and uses sub-roofing materials.

Issue- 2: Too Old Roof

Usually, an old roof can leak after the installation of solar panels if it is 30 years or older. In fact, as a roof age, its shingles may deteriorate due to exposure to various weather elements over the years. Under the shingles, this deterioration can lead to weakened spots and dry rot.

When solar panels are mounted on such a compromised roof, the additional weight can cause extra stress. During rain or other precipitation, these stresses can create gaps, cracks, or holes in the roofing material.

Moreover, an old roof may need an adequate sub-structure that can efficiently support the added weight of solar panels. Over time, sub-structures like rafters and joists may lose their load-bearing capacity. Thus, installing solar panels without proper support can further strain the weakened substructure, increasing leakage risk.

How to Fix:

Follow these tips in order to fix the problem:

• Be sure to thoroughly inspect the roof before installing solar panels.
• Address any issues with deteriorated shingles or weak spots.
• Consider replacing the roof if it is too old or in poor condition.
• Ensure the top has adequate sub-structure to support the solar panels’ weight.
• Consult with a reputable solar installer to assess roof suitability.
• Avoid installing a new solar array on an old roof to prevent future complications.
• Prioritize roof compatibility to avoid potential leaks and water damage.

Issue- 3: Damage Roof

If the roof has pre-existing issues like damaged shingles, cracks, or weakened areas, installing solar panels can exacerbate these problems. Usually, roofs can be damaged by weather elements, age, poor maintenance, or previous construction.

Generally, mounting brackets are attached to the roof by drilling holes and screwing or bolting them into place.

If the top already has weakening areas, such as cracked or missing shingles or damaged roofing components, the drilling and attachment process can further compromise the roof’s structural integrity.

However, during rain or snow, water can easily penetrate beneath the solar panels if the roof has cracked or missing shingles.

Similarly, damaged flashing around roof penetrations can allow water to seep into the roof’s layers. This leads to leaks that may not be immediately apparent but can cause significant damage.

How to Fix:

If you want to resolve this issue, please try these solutions:

• Check the roof before installation to see if any damage has already occurred.
• Install solar panels after repairing any existing roof damage.
• Ensure the roof’s sub-structure is strong enough to support the panels.
• Use high-quality sealants and flashing during installation to create a watertight watertight seal.
• Hire a reputable and experienced solar panel installer for proper installation.

Issue- 4: Incompatible Roof with Solar Panels

Often, roof leaks are caused by the incompatibility of the existing roof with the solar panel installation process.

Typically, solar panels are mounted to residential roofs by drilling into rafters and attaching mounting brackets.

However, some roof materials need to be more suitable for this installation method. Thus, it can lead to leaks and damage.

Usually, solar panels can cause damage to certain materials, including wood shingles, clay tiles, slates, and terracotta tiles.

These materials may not be strong enough to support the weight of the panels and withstand the installation process.

Moreover, these materials may vary in thickness and irregularities, making it difficult to achieve a watertight fit.

How to Fix:

There are several quick fixes you should try:

• Make sure your roof is compatible with solar panels before you install them.
• Replace vulnerable roof areas with more suitable materials, if needed.
• Consult with a professional installer for guidance.
• Use high-quality sealing and flashing during installation.
• Secure mounting brackets properly to avoid gaps.
• Regularly inspect the roof for leaks or damage.
• Utilize the installer’s warranty for any post-installation issues.
