My sister is living near a sea shore area and she has some difficulty with sea gulls. They used to land in her roof and make abundant noise as well as cover the roof completely with poop. She said that she is not able to clean up the roof and it looks really awkward. She is now planning to install a shock reflex track
in her roof in order to chase them away. Will it help?? Also I need some suggestions to clean the roof. How can she clean the roof?? What equipment will she need to reach and clean the roof??
