Ruined my house

Adt came to install their security devices last week Wed. The system works well but the problem is now there's a leakege from the roofing exactly where part of their installation goes. Mind you my house is less than a year and we have never encountered any leakeges from the roof until we installed adt alarm system. The 29/01 there's heavy rain part of the connection is through my kitchen unit which is also being damaged as we speak. I am not gonna pay for the damages please do a plan about my roof and kitchen unit. Im not gonna let these go until you pay for my damaged roof and kichen
