Yes and no, most the time it will work, there are some instance that they are not usable. Example, if you have steel overhanging a long ways with the gutter not going all the way up, you will have a difficult time getting it in there. There is no perfect gutter guard out there unfortunately. It just depends on your job. I apologize if this doesn't help much, I wouldn't be able to confirm a yes or no without being at the location and seeing the job itself.
