  • No leak from roof
  • should walk on joist, use crawling board screw to the joist while working
  • Check and identify cables (some cables are high voltage cables; those may melt if it covered from insulation)
  • Please check if there are any downlights. If it is advisable to cover those from fire rated downlight caps. If you don’t put insulation over the downlight you may keep 50mm gap around the downlight but that may lose your heating and also often you can find fire rated downlights, still we recommend you to cover those downlights with fire rated caps as some by mistake change any of those fire rated downlights to normal downlights it may cause fire.
