Why this matters

A roof can use good material and still leak where sheets meet walls, chimneys, valleys, parapets or service penetrations. Wind-driven rain tests these transitions more severely than a light shower.

Before work starts

Drawings should identify falls, laps, upstands, counter-flashing and compatible sealants. Gutters and outlets need capacity and safe overflow routes so blocked drainage does not push water back into the building.

What to watch on site

Inspect the concealed work before ceilings close access. Photographs, water tests and signed snag items create better evidence than waiting for the first storm to reveal a weak junction.

Handover and the lasting record

At handover, record warranties, cleaning requirements and safe access for maintenance. Roof-leak reporting periods should be understood and defects notified in writing.

Editorial note

This practical article explains a project-control issue using the official reference listed below. Requirements depend on the contract, site, approving authority and current law; the responsible registered professional should confirm the project-specific position.

What we will track next

The next record for Roof leaks often start at the flashing, not the roof sheet should show how approvals, design, inspection and workmanship connect. Drawings and certificates matter, but photographs of concealed work, written instructions, test results and a dated defects list make the project easier to verify.

Owners should keep the signed contract, payment proof, professional appointments, enrolment records where applicable and the final approved plans together. This file becomes most valuable when a leak, crack or service problem appears after occupation.
