Solar-related roofing work for older roofs is about 2% of the roofing work. By about 2025, solar will be on all new houses in the USA. California and some other states have mandated that all new houses will have solar. Solar roofs are about 35-40% of new houses and will be about 50% in 2022. New houses seem to be about 15% of the overall roofing work. There are 85 million detached houses in the USA and about 20 million multi-unit buildings. This re-roofing fraction stays relatively consistent based upon most roofs lasting 20-30 years. ![]() About 7% of houses are re-roofed each year. In 2019, it was about 360,000 solar roof-related installations out of about 1 million new roofs. This would need to include not just new roof but re-roof or installation of solar panels on old roofs and maintenance work. However, this will be large number statistics, where the number of accidents and deaths for solar roof would be a fraction of the total roof work. I could not find a report that breaks out roofing deaths that are solar roof, solar panel related and those that are regular roofing work. In 2020, 912,000 single-family homes completed in the USA and 375,000 multifamily units completed in 2020. The US is installing about 500,000 solar roofs every year. The US is expected to pass three million total solar installations in 2021 and will go over four million solar panel installations in 2023. This was three years after surpassing one million solar panel installations, which took 40 years to accomplish. ![]() had more than two million total solar panel installations. In total, 880 of the deaths in 2019 were due to a fall, slip or trip, an 11% increase from 791. According to BLS, 93 of the 111 roofing fatalities were caused by a fall, slip or trip incident. In roofing, the most common cause of injuries and deaths are fall-related incidents, and is the most cited OSHA violation. ![]() The average rate across all occupations is 3.5, meaning roofing’s fatality rate is roughly 15 times higher than the average. The 2020 BLS’ report shows roofer fatal injury rate of 54 per 100,000 workers, up from 51.5 - an increase of nearly 5%. By comparison, the average rate across all occupations is 3.5. In 2019, this was 51.5 fatal injuries for every 100,000 full-time equivalent workers. Bureau of Labor Statistics (BLS) recently reported that roofing contractors had a work fatality rate more than 10 times the average rate of work fatalities per year in 2018. In the 2020 US Bureau of Labor National Census of Fatal Occupational Injuries report, the data shows roofers accounted for 111 of the 5,333 fatal injuries that occurred in 2019.
