Remove debris
Leaves and sediment reduce working capacity and can block the outlet. Clear only from a safe position or use a trained technician.
Maintenance guide
What should you check before monsoon rain?
Before a heavier-rain period, check the complete roof-edge route: clear debris, inspect joints and outlets, confirm downpipes discharge correctly, and look for roof or flashing defects. Maintenance reduces overflow risk but cannot repair a failed roof detail by itself.

Quick answer
What should you check before monsoon rain?
A safe ground-level check can catch leaves, rust, open joints, sagging, cracked sealant and downpipe blockage. If the roof is high or wet, do not climb it—send photos to a professional and arrange a safe inspection.
Practical checklist
Pre-monsoon checklist
Inspect joints and corners
Look for open seams, corrosion, drips or staining below the gutter line.
Check downpipes and roof edge
Confirm discharge is clear and look from the ground for loose tiles, lifted flashing, cracked sealant or water marks.
Practical checklist
When maintenance is not enough
Repeated overflow
If the gutter overflows after cleaning, check fall, profile, outlet spacing and roof catchment.
Multiple failed joints
Many leaks across a run may justify a new stainless steel gutter or redesigned outlet route.
Roof junction or ponding
A wall, valley, extension or flat slab leak needs the roof detail or waterproofing checked.
FAQ
Questions people ask before booking
These answers explain what can be checked from photos and when an on-site inspection is needed.
How often should gutters be checked?
Inspect before heavier rain periods and after storms when overflow or visible blockage occurs; the useful interval depends on trees and roof type.
Can I clean a high gutter myself?
Do not climb a wet or unstable roof. Use a qualified technician when ladder access, height or roof hazards are involved.
Will cleaning stop every roof leak?
No. Roof tiles, flashing, joints, downpipes and waterproofing still need their own diagnosis.
