• Survey and plan: Document defects, check access and safety requirements, confirm the roof build-up and agree the replacement system.
• Remove failed materials: Strip back to the agreed layer and protect the building while managing waste safely.
• Repair and prepare: Fix substrate defects, check falls and drains, and replace unsound insulation or deck sections as specified.
• Install the new roof: Fit panels or membrane, flashings, edge trims, penetrations, and drainage details to approved instructions.
• Final checks: Inspect seams, fixings, edges, and outlets; document completion and provide maintenance guidance.

Important: Do not assume a new membrane can be installed directly over concrete or an existing roof without checking moisture, substrate condition, adhesion, wind uplift, fire requirements, drainage, and compatibility.

General note and references This guide is not a project specification. Follow local codes, approved drawings, safety requirements, and the selected manufacturer’s installation instructions. Confirm final repair/replacement scope through a qualified roofing contractor.
