Best Practices for Installing Solar Panels on Older Roofs


post img

Older roofs can be full of hidden surprises—and not all of them are good. Beneath weathered shingles and outdated materials, you may find structural weaknesses or code challenges that complicate even the most carefully planned solar installation. Whether you specialize in commercial arrays or residential systems, understanding how to navigate these variables will help you protect your client’s investment and your bottom line. Read on for proven best practices that help you deliver safer, more efficient installations on aging rooftops.

Assess Roof Condition and Load Capacity Early

Before you begin any installation, conduct a thorough evaluation of the roof’s current condition. Older roofs may have hidden issues, such as water damage, rotting wood, or compromised decking that can affect structural integrity. Engaging a qualified structural engineer to assess load capacity can help you avoid expensive surprises later in the project. Confirm that the roof can handle the additional weight of the solar array and mounting system, and document any areas that may require reinforcement or repairs.

Plan for Code Compliance and Permitting

Every jurisdiction has specific building codes and permitting requirements, and some are more stringent for older structures. Review all applicable regulations early, including setback requirements, fire safety codes, and structural guidelines. Securing necessary approvals upfront can prevent delays and protect your clients’ investment. Choosing UL 467 and UL 2703 compliant mounting systems like those from DynoRaxx can help streamline inspections, simplify documentation, and demonstrate your commitment to safety and compliance.

Prioritize Lightweight, No-Tool Mounting Solutions

Older roofs often have reduced load tolerance, making lightweight equipment critical. Fiberglass-based racking systems can significantly cut down on rooftop weight compared to traditional steel or aluminum products. DynoRaxx’s lightweight baskets and toolless design allow you to minimize strain on fragile surfaces while improving installation speed and safety. Fewer components mean less handling, lower risk of damage, and faster project timelines—helping you protect your margins while delivering exceptional results.

Plan Around Roof Lifespan and Replacement Timing

Installing a solar system on a roof near the end of its service life can create unnecessary costs in the near future. Removing and reinstalling panels for roof replacement is disruptive and expensive. Before installation, discuss the roof’s projected lifespan with the property owner and explore options for roof repairs or replacement in tandem with the solar project. Proactive planning ensures that the system stays secure and fully operational without unplanned interruptions.

Communicate Clearly with Property Owners

Older roof projects often require more collaboration and transparency. Make sure clients understand how roof age, condition, and code requirements can impact project timelines and costs. Explain any recommended upgrades, reinforcements, or repairs in clear terms. Providing detailed proposals and honest timelines helps clients make informed decisions and builds trust in your expertise.
