My roofers used a magnet to collect them. I found maybe two or three after they left. I checked recommendations on Nextdoor app, and got three quotes. The owner came out for the quote, got up on the roof to inspect, and he was also there for the job. 2000 sf roof, they started at six AM and were done by lunch, they had another job after lunch. I’ve seem some roofs in the neighborhood take three days.

I was very happy with the job they did. $12,000.
