Why do the manufacturers not want holes in their shingles? Could it be that holes tend to leak!
The satellite dish installers could care less about your roof, their job is to install the dish as quick as they can and then move to the next victim.
So the next time you see this type of roof mounted dish you will know that it is wrong!
The owner of this home kept trying to tell me that it must be OK, because all of the other homes in the area have been done like this. I could not make him understand that Direct TV does not control what is right when it comes to roofing materials.
I have also noted that many home inspectors are not reporting them either. I just finished reviewing three reports from home inspectors who did not note the roof mounted dishes. All three homes have had problems. Two of the homes have roof and wall damage from water leaks and the other had a section of the roof (along with the dish) torn off in a thunderstorm. The dish acted like a sail and as it was only screwed into the OSB decking, that section of the roof took off like a sailboard.
