Evaluating Existing Roofs for Solar Panels

  • Aug 28
  • 4 min read

As homeowners increasingly look to solar energy as a way to reduce their carbon footprint and energy bills, it's essential to evaluate whether your existing roof is suitable for solar panel installation. Understanding the condition of your roof and its potential for solar energy can save you time, money, and headaches in the long run. Let’s explore the critical aspects of evaluating your roof for solar panels, including safety, code compliance, and common issues, and how our structural engineers at Instinct Structural LLC can assist you in this process.


Safety First: Ensuring Your Roof Can Support Solar Panels


Before considering solar panel installation, safety should be your primary concern. Solar panels add significant weight to your roof, and if it’s not structurally sound, this could lead to serious issues, including roof collapse.


When evaluating your roof, consider factors such as the age of the roof, material used, and its current condition. Most roofing materials, such as asphalt shingles and metal roofs, can last 20-50 years if maintained properly. However, if your roof is nearing the end of its life, it might be better to replace it before adding solar panels.


Tip: Have a professional inspect your roof for any signs of wear, damage, or deterioration. Small leaks can lead to significant structural issues over time, especially with increased weight from solar installations. Contact us to setup an inspection!

Understanding Code Compliance for Solar Installations


Once you've confirmed that your roof can handle the weight of solar panels, the next step is to check local building codes and regulations. Compliance is crucial, as failing to follow these guidelines can result in fines, mandatory removal of panels, or even legal issues.


In many areas, local codes dictate specific requirements for solar panel installations, including:


  • Structural integrity assessments

  • Permitting processes

  • Required inspections


Every municipality has different regulations, so it’s vital to consult with professionals who are knowledgeable about your local building codes. Failing to comply with these regulations can set you back significantly in terms of costs and time.

The Benefits of a Professional Roof Assessment


While it may be tempting to assess your roof yourself, hiring experts like our engineers at Instinct Structural provide many advantages. A licensed structural engineer has the training and experience to evaluate your roof thoroughly, ensuring it's safe for solar panel installation.


Some benefits of a professional roof assessment include:


  1. In-Depth Analysis: Our structural engineers will examine your roof’s structure, checking for signs of deterioration or damage that you might miss.

  2. Code Compliance: Professional assessments often include ensuring that your roof meets local building codes, saving you potential complications later on.

  3. Tailored Solutions: If issues are found, our experts can provide specific recommendations for repair or reinforcement. They may suggest adding support beams or fixing leaks before solar panel installation.


A professional assessment is a small investment that can lead to significant savings and peace of mind down the road. Contact us for a free phone consultation.

Common Issues Discovered During Roof Evaluations


During a professional assessment, several common issues may arise that could affect your roof's ability to support solar panels. Being aware of these can help you prepare for necessary repairs or adjustments:


  • Water Damage: This includes visible mold or stains, which can indicate leaks or water intrusion.

  • Structural Weakness: Cracks in beams, sagging roofs, or other signs of structural failure can pose a risk during solar panel installation.

  • Inadequate Drainage: Poor drainage systems can lead to standing water on your roof, exacerbating existing issues and complicating solar installation.


  • Improper Ventilation: Without proper ventilation, your roof can overheat, leading to damage and diminished lifespan for both the roof and solar panels.


Identifying and addressing these issues before installation can save you from costly repairs later.
