Tenant wants to install Direct TV in rental townhome

[Colette Bartos]

Looking for advice - tenant wants to install Direct TV in or rather on my townhome.

What do I need to be consider?  Anybody had to deal with damage as the result of the installation or removal of the dish?  How did you discover the damage, and were you able to recoup directly from the tenant or from the security deposit?  

Do I need to add an addendum to the lease with any specific language?

Any guidance would be greatly appreciated, thank you!
