Regular legal Americans in the roofing installation biz are like bigfoot riding a unicorn. Rumored to exist, but I have never seen one. A legal with passable but poor English usually runs the crew but everyone else on the crew is not exactly legal and does not speak a lick of English. The contractor that hires the crew in is usually American.
How this happened is easy to explain. Someone needed to spend more time in Spanglish class.
“The contractor that hires the crew in is usually American.”
In South Florida, likely Cuban.
Inquiring for help, I asked a crew of seven next door. None spoke English!
