What you will see
- Dampness appearing during rain near the array’s location.
- A leak that began after installation or later roof work.
- Water collecting near supports, penetrations or drainage routes.
- A stain whose indoor location does not clearly identify the roof entry point.
- Record when the leak occurs and whether it changes with the duration or direction of rainfall. These observations can help plan the investigation.
Why it happens
Rooftop PV planning needs coordination with the roof’s condition, attachment details, waterproofing and maintenance requirements. A leak review should examine those interfaces rather than assuming that adding sealant at the nearest support will solve the problem.
Drainage also matters. Debris and obstructions can allow water to accumulate, increasing the risk of roof leaks and damage around electrical equipment.
The inspection should distinguish installation-related damage, later building work and pre-existing roof defects where the evidence allows. If the cause is uncertain, that uncertainty should be recorded rather than concealed by a quick cosmetic repair.
Ask what corrective work is proposed, who will perform it and how the affected waterproofing will be checked afterward.
Where the water could come from
Installation
Supports, penetrations, waterproofing.
Later work
Other trades on the roof.
Existing roof
Defects that were already there.
What you can check yourself
- Photograph indoor water damage from a safe, dry position.
- Note the first occurrence and relevant rainfall dates.
- Gather earlier roof-condition and installation photographs.
- List any waterproofing or building work completed since installation.
- Describe the location using a room name or existing roof plan.
- Avoid positioning buckets or moving belongings where doing so brings you close to wet electrical equipment.
What not to do
- Do not walk onto a wet roof, touch wet switches or electrical enclosures, or drill exploratory holes near wiring. Do not cover the evidence with an unplanned sealant repair before the cause has been assessed.
When to call us
- Report new leaks promptly. If water is entering electrical equipment or approaching exposed wiring, keep clear and seek urgent electrical assistance as well as roof repair.
