Can a metal roof leak at the screws?
Fixings can be one entry point, but laps, penetrations, flashing and drainage should also be reviewed.
Can rust be patched?
That depends on its extent, metal thickness and connected details; a photo alone may not show the full condition.
Why is material compatibility important?
Different metals, coatings and sealants can interact. The existing sheet and adjoining components need to be identified before materials are selected.
Does a visible seam show the whole leak source?
Not always. Water can travel along laps, penetrations or drainage details before it appears at the visible mark.
When might metal roof work involve roof plumbing?
Work on roof drainage, flashings or other regulated components may require an appropriately registered practitioner once the exact scope is known.
