Roofs on residential homes are usually not designed to accommodate extra equipment that is common on commercial buildings.
Your roof protects you, your personal possessions and all the building materials installed underneath it. If you allow contractors to perforate your roof, there will undoubtedly be leaks down the road and ultimately you will be forced to pay to fix the leaks. The only method to repair leaks is to remove the installed equipment in order to access your damaged roof underneath. Therefore, you will have to pay the installers to remove their equipment, and then pay a roofing contractor to repair your roof.
I recently inspected a house that had an internet antenna with a very tall tower installed on the roof.
The roof consisted of clay tiles on top of typical metal laminates. The installers made perforations at the top for a bracket to support the antenna tower and then they connected various cables to support the tower that are attached to steel plates that perforate the roof tiles and metal laminates in various areas of the roof. When the wind blows, the tower and its supporting cables are being stressed and the metal plates are pulling on the roof laminates, and gradually, the installation screws to attach the laminates are being pulled out.
Installing antennas, solar or air conditioning equipment on residential roofs is irresponsible, unless the roof was specially designed to accommodate this type of equipment. The installers for the antenna on this roof broke at least fifteen clay tiles during the installation, and this greatly increases the chances of roof leaks.
Understand that the installers who arrive at your home are usually subcontractors for the service providers, and these guys are paid to install the equipment as quickly as possible and connect you to the service.
The sooner they complete your installation, the sooner they can go to their next client and make more money.
Homeowners have the option of telling the providers of equipment to put their installations on the ground and not on the roof of the home. If you avoid installations that perforate your roof, you will save yourself many headaches and avoid leaking roofs.
