The stain is not always directly below the leak.
Water can travel along roof sheets, flashing, membranes, ceilings and structural junctions before it becomes visible. That is why leak repair starts with assessment, not guesswork.
Repair the cause, not only the ceiling mark.
Metal roofs
Fasteners, laps, penetrations, flashings and corrosion can all become leak paths.
Pitched roofs
Ridges, valleys, broken tiles, underlay and roof junctions require systematic inspection.
Concrete roofs
Cracks, membrane failures, outlets, parapets and standing water can contribute to leaks.
Box gutters
Overflow, blocked drainage, failed joints or inadequate waterproofing can affect adjacent interiors.
Useful information before the site visit.
When does it leak?
Only in wind-driven rain, during heavy storms, after prolonged rain, or even when it is dry?
Has it been repaired before?
Previous coatings or patch repairs can change both the diagnosis and preparation required.
Where is the visible damage?
Photos of stains, cracks and exterior roof areas can help frame the initial assessment.
Stop active damage, then fix properly.
Temporary measures can sometimes reduce immediate water entry, but permanent repair still depends on finding the underlying failure and installing a suitable system.
