There are 135,580,000 housing units in america. If we assume an average of 30 squares per unit, or a total number of 4,067,400,000. Four billion and some change squares. Assuming a very generous rate of 2 squares/day, that’s 16,269,600,000. Sixteen Billion hours to roof every “housing unit” (at assumed 30 squares). There are 2080 hours in a standard work-year meaning it would take 782,163 years of labor to roof every house. The “Roofing community” on Facebook has about 18k members. So if every member was trained and did only permanent roofing for 43 years, we could roof the entire building stock, forever. Since we already know seamed roofs in copper can last up to 800 years (St. Mary’s Cathedral, Hildesheim) We could eliminate the entire disposable roof market with only 18k people, and 43 years. In the span of one career, you can change the world.
