Leak around fixings of TV aerials and satellite dishes

Cause

Sealing washers to fixings were left out at installation 

Repair

  • roof leaks should be attended to without delay to avoid the risk of damage below the roof cladding
  • if the TV aerial or satellite dish was installed recently by a tradesperson or company installer, call them back to fix the problem
  • fixings for aerials and dishes through roof claddings should include sealing washers to keep the penetration weathertight
  • the fixing (and the washer) should be appropriate for the roof cladding type and profile
  • when the fixing is installed, the washer (often made from EPDM) should compress slightly when the fixing is tightened to provide a good seal against the cladding. Don’t overtighten the fixing
  • ensure all materials are compatible. In E2/AS1, Tables 20 and 21 refer to materials in contact and materials subject to runoff view here
  • when using a ladder to climb onto a roof, ensure it is on a firm and level base. The base should be 1.0 metre out from the wall for every 4.0 metres of height. Secure the top of the ladder where possible
  • tell someone when you are planning to work on a roof
