Your roof insulation could be improved
You don't have roof insulation that meets HomeFit standards. Ask an insulation supplier and installer to install R3.3 blanket insulation, or R4 segment insulation. See the supplier directory in the report section for a list of installers
You may have downlights that require a gap in the insulation. These will need to be upgraded to meet the HomeFit standard (see an installer or electrician).
