My concern is because you open the structure to the elements; you compromise the original strength of a wall, floor or roof. My training was never to pierce the structure or shell if not required. I'm not saying I won't, but I will think two to three times before I do that, I also ask other experts just to make sure I'm not making a mistake. I try to see if there's another option. Not everyone preps or applies sealants correctly. Sealants/glues can and have failed, especially if applied incorrectly and for age.
