wood-framed roof is about 15 pounds per square foot. The load increases with the use of heavier roofing material. A clay-tiled roof may have a dead load of as much as 27 psf. LIVE LOADS
Roof load refers to the total weight or force that is imposed on a roof by various factors, such as the weight of the roofing materials, snow, wind, and other environmental factors. There are two main types of roof loads: dead load and live load. Dead Load. Dead load is the weight of the roof itself, including the materials used for construction.
Section 1607.13.5.1 in the 2019 IBC implies that if the roof was designed for 20 psf live load, you do not need to double count weight of solar panels assuming the reaction is not larger than the 20 psf roof live load design. This is assuming

A solar panel roof load calculator can help you determine the size and weight of solar panels your roof can accommodate. This article explains some of the core factors determining whether a roof can support a solar system and provide a formula to determine your roof load.
To calculate the area of one panel, multiply by the number of panels to get total area, and ensure it does not exceed the roof's usable space, considering orientation and tilt. Will My Roof Take the Weight of Solar Panels?
The final step in ensuring your roof can support a solar panel installation is to calculate the distributed load. To calculate the distributed load, we need to divide the total weight of the solar panel system (including panels and mounting hardware) by the total array area we've calculated.
To calculate the distributed load, we need to divide the total weight of the solar panel system (including panels and mounting hardware) by the total array area we've calculated. This gives us a weight per square foot measurement, which is crucial for assessing the structural integrity of your roof.
The point load represents the pressure applied to specific points where the solar panels and their mounting hardware attach to the roof. It's like pinpointing exactly where your roof will need to support more weight to ensure those spots can handle it without any issues.
Total Array Area = Area of One Panel × Number of Panels If you are installing 10 panels, the calculation would be: Total Array Area = 15 sq ft × 10 = 150 sq ft This means the solar panels will occupy a total area of 150 square feet on your roof. 3. Calculate Distributed Load
