Assessing existing roof insulation before replacement

Document the existing insulation and arrange a competent inspection before planning removal or replacement. Record visible concerns and access limitations so the proposed scope addresses the cause of the problem, rather than covering it up.

Define the selection

Keep the product comparison linked to the project assessment. Ask for the current datasheet and installation guide for the exact code being considered; a catalogue selection is not a substitute for a coordinated building specification.

Check before comparing products

• Existing material and installation condition.
• Moisture or access concerns needing assessment.
• Removal, disposal and replacement scope.

Build a material list that can be checked

Record the selected product name or SKU, each required size and the quantity for each work area. Use the actual listed coverage when estimating packs or boards, and confirm the allowance with your installer. Include compatible accessories and keep a copy of the agreed selections.
