Had roofers redo the roof awhile ago. I checked the lawn for errent nails thinking I'd find none or two. It went from mildy to infuriating.
Still cleaning up roofing debris from when my roof was replaced in 2014, or before that, and have found plenty of pieces of glass from old windows, and tile pieces that were probably from the original 1956 build...
Builders need to remember to keep it clean and clean up after, 100%!
