Before installing solar panels, it’s important to evaluate the condition of your roof since solar systems have a lifespan of 20 to 30 years or more. A roof that is near the end of its life could require replacement shortly after solar installation, which means removing and reinstalling your panels, adding to your costs and hassle. Roofs typically need replacing due to age, visible damage like cracked or missing shingles, leaks, or sagging. To check if your roof might need replacing before going solar, start with a simple visual inspection from the ground and attic. Look for signs such as curling shingles, granule loss, dark streaks, or damp spots inside the house. If you’re unsure about what you see, using a cell phone photo or video for closer inspection or consulting online guides can help you better understand the roof’s condition.
If your roof shows signs of aging or damage, it’s best to call a licensed roofer for a professional assessment before proceeding with solar installation. When you speak with the installer or roofer, ask specific questions such as “How many more years would you estimate my roof will last?” and “If I replace my roof, can you coordinate the timing of roof work and solar installation for minimal disruption?” This ensures your roof and solar warranty terms are compatible and you avoid unnecessary removal costs. Solar companies also often offer a roof inspection as part of their consultation, so check if that service is available. Remember, a solid roof underneath your solar panels means better protection, fewer repairs down the line, and a safer, more efficient system overall.
