Roof Replacement With Full Decking Replacement After Solar-Related Leaks

Full roof replacement, plywood decking replacement, chimney flashing, ridge vent installation, and solar provider coordination.

This project involved a full roof replacement for a homeowner dealing with active leaks in multiple areas of the home. Before roofing work could begin, the project required coordination with the solar provider because the existing panels were part of a PPA solar system and could not be removed directly by our team.

Once the panels were removed and the roof was opened, Peak Quality Roofing found significant roof decking deterioration caused by long-term water intrusion. This expanded the project from a standard shingle replacement into a full roof deck replacement with a complete new roofing system.

The reroof installation itself was completed efficiently once work began, but the overall project required careful planning, communication, and coordination because of the solar system logistics.

When Roof Leaks Pointed to a Bigger Problem

The homeowner contacted Peak Quality Roofing after dealing with several active leaks throughout the property. The leaking was not isolated to one small area. Water was entering through multiple points in the roof system and had been affecting the interior of the home over time.

During the inspection, there was clear evidence of ongoing water intrusion, including buckets placed inside the attic to catch incoming water. The homeowner also suspected that the existing solar panel system was contributing to the problem.

Key issues included:

Active leaking in multiple areas of the home
Water intrusion visible inside the attic
A solar panel system installed over the existing roof
Roofing concerns that could not be solved with temporary repairs
Deteriorated roof decking beneath the shingles
Need for solar provider coordination before roofing work could begin

Because of the extent of the leaking, this project required more than a surface-level repair. The roof needed to be opened, evaluated, and rebuilt properly to restore long-term protection.

What We Found After Tear-Off

Once the roofing work began and the old roof system was removed, the extent of the damage became clear. The roof decking had suffered substantial deterioration from prolonged water exposure.

This was not simply a shingle issue. The plywood beneath the roof system had been compromised, which meant the home needed a full roof deck replacement before the new roofing system could be installed.

Our assessment confirmed:

The roof decking had widespread moisture damage
Multiple plywood sections were no longer suitable for reuse
Long-term leaking had affected the structure beneath the shingles
A full decking replacement was needed for a proper installation
New flashing and ventilation details were needed as part of the rebuild

Replacing the damaged decking was one of the most important parts of this project. Without correcting the compromised roof base, a new shingle system would not have had the support it needed to perform properly. The homeowner was very cooperative and also relied on input from family members during the decision-making process, so we made sure the scope and next steps were explained clearly as conditions changed.

Coordinating the Roof Replacement Around the Solar System

One of the most important parts of this project was the solar panel coordination. The home had a PPA solar system, meaning the solar provider retained ownership of the panels. Because of that, Peak Quality Roofing could not remove or handle the panels directly.

The solar provider had to coordinate the panel removal before roofing work could start. This added significant lead time to the project, with approximately six weeks needed before the panels were removed and the roof was ready for replacement.

This coordination included:

Confirming the solar system ownership structure
Waiting for the solar provider to remove the panels
Keeping the homeowner informed during the delay
Planning the roofing work around the solar removal timeline
Preparing the roof for future solar panel reinstallation

This project is a strong example of how roofing work can become more complex when solar panels are involved, especially with leased or PPA solar systems. Clear communication and proper sequencing were important throughout the process.

The Roofing System We Installed

For this roof replacement project, Peak Quality Roofing installed a complete asphalt shingle roofing system using GAF Timberline HDZ shingles in Weathered Wood.

The main roofing materials included:

GAF Timberline HDZ shingles in Weathered Wood
GAF Pro-Start starter strips
GAF Seal-A-Ridge cap shingles
ABC Pro Guard synthetic underlayment
Ice and water shield
White aluminum drip edge
Aluminum step flashing
Lead roll flashing
Ridge vent system
New plywood roof decking

Together, these materials helped rebuild the roof from the decking level up, creating a stronger foundation, better leak protection, improved ventilation, and a complete roofing system ready for long-term performance.

Rebuilding the Roof System the Right Way

After the damaged materials were removed, Peak Quality Roofing completed a full roof deck replacement and installed a complete new roofing system. The goal was to restore the roof from the structure beneath the shingles all the way to the final finished surface.

The project also included new chimney flashing and ridge vent installation to improve protection around key roof areas and support better ventilation.

Our work included:

Full roof replacement
Full plywood roof decking replacement
Removal of damaged roofing materials
Installation of a complete new roofing system
New chimney flashing installation
New ridge vent installation
Roof ventilation improvements
Final cleanup and inspection

Once the solar panels were removed and the project was ready to begin, the roofing installation was completed efficiently in a single day. The larger timeline was mainly due to the required solar provider coordination before the roof work could start.

Long-Term Protection After Full Roof Deck Replacement

By the end of the project, the homeowner had a fully rebuilt roof system designed to address the active leaks and the damage caused by long-term water intrusion. The full decking replacement gave the new roof a solid foundation, while the updated flashing and ridge ventilation helped improve the system’s overall performance.

Key outcomes included:

Active leak issues addressed with a full roof replacement
Damaged plywood decking removed and replaced
A stronger roof foundation beneath the shingles
New chimney flashing for better water protection
Improved ventilation through ridge vent installation
Roofing work coordinated around the solar provider’s timeline
A complete roofing system ready for future solar panel reinstallation

This project shows why active roof leaks should be inspected carefully. When water intrusion continues over time, the damage can move beyond shingles and affect the roof decking underneath.

Roofing Help for Homes With Solar Panels

Roof replacements involving solar panels require extra planning, especially when the panels are leased or part of a PPA system. In those cases, the solar provider may need to remove and reinstall the panels before roofing work can be completed.

Roof Replacement FAQs for This Solar Panel Project

Can a roof leak happen around solar panels?

Yes. Roof leaks can happen around solar panel mounting points, flashing areas, or roof penetrations if the system was not properly integrated with the roof. In this project, the homeowner was experiencing multiple active leaks and suspected the solar panel system was contributing to the issue.

Did Peak Quality Roofing remove the solar panels?

No. Because the solar panels were part of a PPA solar system, the solar provider retained ownership of the panels. The solar company had to remove the panels before roofing work could begin. Peak Quality Roofing coordinated the roof replacement around the solar provider’s timeline.

Why did the project take longer before roofing work started?

The project required additional lead time because the solar provider had to remove the panels first. Since the system was not homeowner-owned, PQR could not remove or handle the panels directly. Once the solar panels were removed, the roofing work was completed efficiently.

Why was full plywood decking replacement needed?

Once the old roofing system was removed, the roof decking showed significant deterioration from long-term water exposure. Replacing the damaged plywood was necessary to give the new roof system a solid foundation.

What should homeowners do if they have roof leaks under solar panels?

Homeowners should schedule a roof inspection and contact their solar provider if the panels need to be removed. A roofing contractor can inspect the roof condition, identify leak sources, and explain whether repair, decking replacement, or full roof replacement is needed.
