Jeff's company normally does not go on roofs. Not for safety theater -- for real reasons: fall hazard, two-story risk, roof damage risk, brittle old solar piping, insurance coverage limits, and roofing scope. This does not mean the leak cannot be identified. It means the leak detection company must stay inside its safe and insured scope.
Solar Leaks Are Usually Found by Behavior
When the solar system runs, pool water is pumped up to the roof. If there is a pinhole leak in a panel, header, riser tube, coupling, valve, or rooftop pipe, the water often becomes visible -- from the ground.
What to Watch While Solar Runs
- Water running down the roof surface
- Wet area on a dry roof
- Water dripping from the roof edge
- Water dripping from fascia or soffit
- Water coming from gutter drains
- Water streaking down exterior walls
- Air or bubbles entering the system
Behavioral Comparison
- Observe pool with solar OFF
- Observe pool with solar ON
- Watch whether visible water appears only when solar loop is active
- Check whether water loss rate increases only when solar runs
- Note whether air appears in returns only with solar operating
If water appears only when the solar loop is operating, that strongly supports a suspected solar leak. The report should say "suspected solar leak based on visible operating evidence" -- not "confirmed rooftop defect" -- unless the actual leak point was safely observed and documented.
Why Old Solar Systems Should Not Be Aggressively Pressure Tested
Old solar panels, headers, couplings, and rooftop PVC can become weak and brittle over years of UV exposure and temperature cycling. Aggressive pressure testing can turn a small pinhole into a broken system. Jeff's company normally avoids pressure testing old rooftop solar systems for this reason. If a qualified person with the appropriate scope, training, and insurance performs a test, the logic follows normal pressure-test principles -- isolate the section, use controlled pressure, watch for loss. But for old solar systems, low-pressure water testing with manufacturer guidance is the safer concept. No specific pressure numbers should be published for public use.
Ultrasound as a Support Tool
A trained technician may sometimes use ultrasound to listen for leak sounds while the solar system is under pressure or running. This can support the diagnosis when visible evidence is ambiguous. It is a support tool -- not a guaranteed answer and not a replacement for safe visual observation.
The H.U.N.T.E.R. Method: Scope Control
This page is fundamentally about scope control. H.U.N.T.E.R. keeps the technician from taking dangerous actions outside their training and coverage just to reach a conclusion.
Ask when the loss started. Ask whether it happens only when solar runs or all the time.
Understand the solar system layout, pipe age, and access before deciding what can safely be done.
If loss only occurs with solar on, narrow the suspect to the solar loop -- from a safe ground-level position.
Test only what can be tested safely. Visual observation while the system runs. Ultrasound if trained. Do not climb.
Document visible water evidence from a safe location. Photograph roof runoff, gutter drains, and wall streaking.
Recommend referral to a qualified solar or roofing contractor for rooftop confirmation or repair.
My company does not go on roofs. That is a real policy, not a talking point. Two-story fall risk, brittle solar piping that can shatter if you step on it, insurance limitations, and the fact that rooftop solar repair is a different trade than pool leak detection.
What I can do from the ground is run the solar system and watch. If water is running down the side of the house only when the solar pump is running, that is a suspected solar leak. That goes in the report. The customer then contacts the solar company or a roofing contractor to get on the roof safely with fall protection and the right tools.
Knowing when to refer is part of professional leak detection. It is not a failure. It is the correct recommendation.
Beginner vs. Advanced
Beginner Rules
- Do not climb two-story roofs casually
- Compare solar on vs. solar off water behavior
- Watch roof runoff and gutter drains
- Document what can be seen safely
- Do not pressure test old solar systems aggressively
- Refer rooftop solar inspection and repair
Advanced Evaluation
- Solar valve and bypass behavior
- Air entering system only when solar runs
- Ultrasound support while system runs
- Equipment-side solar plumbing leaks
- Ground-level evidence documentation
- Coordination with solar or roofing contractors
Common Mistakes
- Going on a roof outside training or insurance coverage
- Aggressively pressure testing brittle old solar panels
- Missing gutter drain evidence while solar is running
- Blaming underground plumbing before checking solar operation first
- Ignoring air that appears only when solar runs
- Failing to state in the report that roof work is outside scope
- Promising rooftop leak confirmation from ground-level evidence alone
Frequently Asked Questions
Can a pool leak company diagnose a rooftop solar leak without going on the roof?
Sometimes. A suspected solar leak can often be identified from ground-level by observing operating behavior and visible runoff while the solar system runs. Actual rooftop confirmation or repair requires a qualified solar or roofing contractor with proper fall protection and access equipment.
Should old solar systems be pressure tested?
Not casually. Old rooftop solar systems can have brittle panels, weakened couplings, and aged PVC that may fail under aggressive test pressure. Jeff's company normally avoids pressure testing old solar systems for this reason.
What is the most useful diagnostic step for a suspected solar leak?
Run the solar system and observe the roof, roof edge, fascia, gutters, and downspouts from a safe ground-level position. Compare water behavior with solar on versus solar off. If water appears only when the solar loop is active, that is meaningful evidence of a suspected solar leak.
Can ultrasound help find solar leaks?
Sometimes -- as a support tool. Ultrasound may help a trained technician detect leak sounds while the system is under pressure or running. It is not a guaranteed method and does not replace safe visual observation and proper referral.
