Roof penetrations and wall wrap at lock-up

The water details that close over at a Sunbury lock-up, and the ones we keep finding open.

Sunbury 3429 · 2026-05-14

In short: Lock-up is the last look at the roof and wall wrap from the inside. Unflashed penetrations and torn wrap are the items we find most.

Roof penetrations

Every pipe and vent through the roof needs a flashing. One left open lets water straight into the ceiling space.

Wall wrap

Wrap behind the cladding is a second line against wind and water. Tears and untaped openings weaken it.

Frame items carried over

On one Sunbury job, items from the frame report were still open at lock-up, which is the last chance before plaster.

Gutters and sumps

Unclipped brackets and an unsupported box gutter sump were also recorded on Sunbury lock-ups.

FAQ

Questions Sunbury owners ask about this

Why check the roof from inside?

Penetrations and sarking are easiest to see from the roof space before ceilings go up.

Is torn wrap a big problem?

It is a defect worth fixing with tape before cladding and plaster hide it.

What if frame items are still open?

The report lists them again so they are fixed before plaster.

Do you check insulation?

Yes, for coverage and missing batts.
