A leaking roof needs prompt attention, but your first priority should be keeping people safe and limiting damage inside the property.
Water appearing on a ceiling does not always mean the roof is leaking directly above that spot. Water can enter through damaged roofing, flashing, screws, skylights or gutters, then travel through the roof space before becoming visible indoors.
PMR Profilio Metal Roofing repairs metal roof leaks across Wollongong, Shellharbour and the wider Illawarra. This guide explains what to do during an active leak, common causes of metal roof leaks and when repair or roof replacement may be required.
Common Causes of Metal Roof Leaks
Metal roof leaks can have several causes, and the visible water stain inside the building may be some distance from the original entry point.
Common causes include:
- Loose, missing or deteriorated roof screws and washers
- Corrosion around fixings, sheet edges or roof penetrations
- Damaged, lifted or incorrectly installed metal roof sheets
- Cracked or poorly sealed flashing around walls, chimneys and roof junctions
- Problems around skylights, vents, whirlybirds or other penetrations
- Blocked or overflowing gutters and valleys
- Storm, hail or falling-branch damage
- Previous patch repairs beginning to fail
- Incorrect roof pitch, sheet overlap or installation details
- An ageing roof with widespread deterioration
Locating the source of a leak often requires a professional inspection. Applying sealant to the visible area without identifying the cause may temporarily hide the problem rather than fix it.
What to Do When Your Roof Starts Leaking
1. Keep Clear of Electrical Hazards
If water is near lights, power points, appliances or electrical wiring, keep away from the area. Do not touch wet electrical fittings.
Where it can be done safely, switch off power to the affected area at the switchboard. Contact a licensed electrician if you are uncertain or there are signs of an electrical hazard.
2. Move People and Belongings
Keep children and pets away from the leaking area. Move furniture, electronics and valuables to a dry location where possible.
Cover larger items with plastic sheeting or a waterproof tarp if they cannot be moved.
3. Contain the Water
Place a bucket or waterproof container beneath the drip. Put an old towel underneath the container to absorb splashes and reduce the risk of slipping.
Check the container regularly and replace or empty it before it overflows.
4. Relieve a Bulging Ceiling Only if Safe
If water is collecting above a plasterboard ceiling, the ceiling may begin to bulge and could eventually collapse.
Keep everyone away from the area. Do not stand directly beneath the bulge. Where there is any electrical risk, uncertainty or significant sagging, leave the area and contact an appropriate professional rather than attempting to release the water yourself.
5. Photograph the Damage
Take clear photographs or video of the leak, water stains and damaged belongings where it is safe to do so.
These records can be useful when speaking with your roofer or insurer.
6. Contact a Roofing Professional
The indoor steps above only manage the immediate symptoms. The entry point still needs to be located and repaired.
PMR provides roof inspections and metal roof leak repairs during normal business hours. We do not offer after-hours emergency leak repairs.
During severe weather, do not climb onto the roof or attempt repairs yourself. Wait until conditions are safe and arrange a professional assessment.
What Should You Avoid During a Roof Leak?
During an active leak:
- Do not climb onto a wet roof
- Do not attempt repairs during rain, strong wind or lightning
- Do not walk through water near electrical equipment
- Do not rely on silicone or sealant without finding the cause
- Do not pressure-clean the area to search for the leak
- Do not ignore a leak because it stops when the rain ends
- Do not assume the visible ceiling stain is directly below the roof defect
Metal roofs can be extremely slippery, and walking on unsupported or damaged areas can cause injury or additional roof damage.
How Is a Metal Roof Leak Located?
A roof leak investigation may include checking:
- Roof sheets, laps and fixing points
- Screws, washers and fasteners
- Ridge, apron and barge flashings
- Valleys and drainage paths
- Skylights, vents and other roof penetrations
- Gutters and downpipes
- Corrosion, punctures or lifted roofing
- Previous repair areas
- Visible signs of moisture inside the roof space, where access is available
Because water can travel along roofing materials, insulation or framing, the source may not be directly above the internal stain.
Once the likely entry point has been identified, PMR can explain whether an isolated repair is suitable or whether more extensive roofing work may be needed.
Can a Leaking Metal Roof Be Repaired?
Many metal roof leaks can be repaired where the problem is isolated and the surrounding roofing remains in serviceable condition.
A repair may involve:
- Replacing damaged screws or washers
- Repairing or replacing flashing
- Replacing a damaged sheet
- Correcting an issue around a skylight or penetration
- Repairing gutter or valley drainage
- Removing failed patching and completing a more suitable repair
Complete roof replacement may be worth considering where corrosion is widespread, several areas are failing, previous repairs have not lasted or the roof is approaching the end of its serviceable life.
PMR can assess the visible condition and explain whether a targeted repair or a new metal roof is likely to provide the better long-term outcome.
What if the Leak Started After a Storm?
If the leak followed hail, strong winds, falling debris or another severe weather event, photograph visible damage where it is safe and contact your insurer promptly.
Your insurer may have requirements about assessments, emergency work and authorisation of repairs. Avoid committing to major permanent work before checking the claims process, unless immediate action is required to make the property safe.
Keep copies of reports, photographs, invoices and communication relating to the damage.
Insurance cover varies between policies. PMR can assess and quote roofing work but cannot determine whether an insurance claim will be accepted.
