Water appearing near a wall, roof junction or penetration may need investigation of the flashings and surrounding roofing. ACG Roofing & Plumbing handles metal roofing and roof-plumbing enquiries, including flashings and cappings. Describe the leak and send safe photos to start the discussion.

Flashing and penetration detail

Flashing and the surrounding roof work together
A visible gap or earlier patch may be only part of the issue. The condition of adjoining sheets, junctions and drainage can affect the proposed repair. An assessment helps identify the components that need attention rather than assuming the visible stain marks the entry point.
Common enquiry locations
- Roof-to-wall junctions
- Junctions between adjoining roof sections
- Roof penetrations and associated flashings
- Cappings and sheet connections
- Flashing details beside gutters and roof drainage
Repair or replacement of the affected detail
The appropriate approach depends on the existing material and profile, deterioration, access and how the detail connects to the roof. ACG can discuss the proposed scope, including associated sheet or roof-plumbing work where required. Confirm what the quote covers before work proceeds.
Help us understand the problem
Include the suburb, where water appears, when it happens, any previous repairs and roof photos taken from a safe position. Plans or earlier reports can also help. A site assessment may be necessary before confirming the cause or repair scope.
Flashing repair questions
Can sealant alone fix the leak?
It depends on the cause and condition of the detail. Discuss the existing junction and surrounding roofing rather than assuming a surface patch is sufficient.
Do all flashing problems need a new roof?
No. A localised problem may suit targeted work when the surrounding system is suitable. Widespread deterioration may call for a broader discussion.
What determines the price?
Access, extent, materials, adjoining components and investigation requirements affect the quote.
Where can I find related services?
