We found these points on a house. We have permision to remove them, but will have to put holes in the coating on the metal roof, (if will fix if i take them off). Since i don't know much about lightning rod points, i don't know if it is worth all the trouble. If any one could help me i would appreciate any info i could get. We already got the insulators off the side of the house, i will post pictures of them later.
