Installing Rooftop Solar Panels

With the advancements in technology and the decrease in the cost of equipment, solar panels have become a popular source of energy solutions throughout many communities. After seeing your neighbor’s home with rooftop solar panels, you begin to want some of your own. However, before you make the jump, there are a few things to consider from a home improvement standpoint.

Ask yourself these questions: 

  • What does my roof look like?
  • What is the condition under my roof?
  • What is the warranty on both my roof and the solar panels? 

What To Look For

Solar panels should always be installed on a new roof, or at a minimum, a roof that is only a few years old. An average lifespan of an asphalt shingle roof is 20 to 30 years depending on the materials used. Inspecting your roofing system is not only looking on the outside, it is also about looking at the condition of the roof on the inside. In your attic space, a homeowner should inspect for damaged rafters or trusses, leaks or stains, dark looking spots and mildew. If your roof reflects any of the warning signs above or hasn’t been replaced in the last 10 years, consider getting a roofing estimate from a professional roofing contractor.

Also, it is important to ask yourself, what is the warranty on the roof compared to the warranty on the solar panels? It wouldn’t make much sense if the roof will only last another 10 to 15 years, while the life of the solar panels could last in some cases almost 20 years. This would require the removal of the solar panels in order to have a replacement roof installed, and then the reinstallation of the solar panels back on the new roof. 

Understanding the cost and harm of installing these rooftop solar panels on an older or damaged roof can save you thousands of dollars in repairs down the line and protect your investment from any future issues.
