Lightning protection system annual maintenance checklist

The annual lightning protection system service is the deep pass: the measurements, cleanings and tests a quarterly round doesn't reach. This checklist keeps the full service on record with the photos that make it defensible later. Work is commonly verified against NFPA 780, the applicable building code. Confirm the edition your authority having jurisdiction has adopted.

The checklist

Every item, and the photo evidence it needs

The photo count on each row is what RTI would require before the item can be submitted. Work the list here and watch the gate hold, or load it into RTI and let it enforce the real thing.

01

Before the inspection

  • Inspector's qualification and the prior report on file

    The inspector's lightning protection qualification recorded, and the last report and system drawings pulled so this visit is read against them.

    No photo
  • Inspector escorted on the roof under the fall protection plan

    Inspector briefed on the site's fall protection procedure, access route and edge controls agreed, and roof hazards from other trades pointed out first.

    No photo
02

Inspection observed

  • Inspector's continuity checks observed and recorded

    Watch the inspector check down-conductor continuity to ground, record which downleads were checked and the outcome the inspector reports.

  • Terminal, conductor and bond survey observed

    Inspector's survey of terminals, runs and bonds observed across the roof, deficiencies the inspector calls out photographed and listed.

  • Rooftop equipment added since the last inspection reviewed

    Each unit, antenna, rail or solar rack added since the last report listed for the inspector, and its bond into the system observed or noted missing.

    No photo
  • System compared against the as-built drawings

    Terminals, runs and downleads on the drawing matched to the roof with the inspector, and anything added, removed or rerouted marked up for the record.

    No photo
03

Grounds and connections

  • Ground connections and test wells opened and observed

    Test wells opened with the inspector, connections examined for corrosion or looseness, condition the inspector reports recorded.

  • Inspector's ground readings recorded by location

    Where the inspector measures ground resistance at the test joints, each reading and its downlead recorded against the last report for the inspector to judge.

    No photo
  • Tie to the building grounding electrode system observed

    The inspector's check of the interconnection between the system grounds and the building electrical ground observed at its accessible point and recorded.

    No photo
  • Every downlead left connected to ground after the inspection

    Each downlead seen connected to its ground, any test joint opened for the inspection remade with bolts tight and any well lid lifted seated again.

04

Findings and records

  • Inspection report filed and deficiencies assigned

    Inspector's report attached to the maintenance record, each deficiency given a follow-up owner and the next inspection date noted.

  • Last report's deficiencies checked off on the roof

    Each item on the prior report found repaired, or carried onto the new report with its original date so a repeat defect shows as repeated.

    No photo
  • Listed installer's inspection status recorded

    Where the system holds a UL or LPI certification, its status and the listed installer's inspection noted; renewal stays with the listing body and the installer.

    No photo

What usually sends this back

The failures are almost always the evidence, not the work

  • Inspector's findings left on the inspection report and never turned into work orders, so the same loose terminal shows up year after year.
  • Down-conductor continuity called good from a visual only, with the inspector's actual continuity check never observed or recorded.

Common questions

6 answers

What does this lightning protection system annual checklist cover?
13 items across 4 sections, covering before the inspection, inspection observed, grounds and connections, findings and records. Each item spells out what the person walking the job is actually looking for, not just a box to tick.
Who should run this inspection?
The facilities lead documenting the visit while the qualified lightning protection inspector performs the periodic inspection.
When in the schedule should this walk happen?
On the periodic cycle, scheduled with the inspector so the continuity checks and any findings are witnessed and recorded, especially after major roof work.
Why do these items ask for a photo?
5 of the 13 items call for photo evidence, 7 photos in all. A checklist answer without the photo is a claim; the photo is what makes the record worth something in a dispute and lets a reviewer approve work without re-walking the job.
What most often fails a lightning protection system annual inspection?
Inspector's findings left on the inspection report and never turned into work orders, so the same loose terminal shows up year after year. Down-conductor continuity called good from a visual only, with the inspector's actual continuity check never observed or recorded.
Can I use this checklist in RTI?
Yes. Start a free RTI workspace, build this list as a checklist, and the Photo Gate holds the submit button until every mandatory item is answered and its photos are attached. Approved inspections roll into a branded turnover package with a tamper evident audit trail.
