How do I know if my roof can handle solar panels

Before contacting installers, inspect your roof for age, condition, and available space. Walk around your house at different times of day to note which areas receive direct sunlight. Check for large trees, neighboring buildings, or chimneys that cast shadows, as these reduce panel efficiency.

Structural requirements

Your roof needs to support roughly 2 to 4 pounds per square foot of additional weight. Most residential roofs built after 2000 handle this easily. If your roof is nearing the end of its lifespan, replacement before solar installation saves money and hassle later.

Space and orientation

A typical home needs 300 to 400 square feet of unobstructed roof space. South facing is ideal in the northern hemisphere, but west or east facing roofs can work too. North facing roofs rarely generate enough power to justify the cost. If your roof doesn't fit the bill, ground mounted systems are an alternative worth exploring.
