Commercial Roof Leak Incident Log for Los Angeles Property Managers

A leak log records when and where someone saw water, who saw it and who they told next. It keeps those facts in order, so the next person does not have to guess. It does not diagnose the roof or decide who pays for the damage.

Keep what people saw apart from what a roofer later finds. Each gets its own column, with a name or role and a date.

Record only what you can see from the floor in spaces you already use. Do not climb onto the roof, lift ceiling tiles or stand on ladders or furniture for a better look. If water drips near lights or a ceiling sags, keep people clear and tell the building manager.

This blank commercial roof leak incident log gives every sighting of water its own row. Print the page, or copy the column names into a spreadsheet. If the same location leaks again, add a separate row that refers back to the earlier incident ID.

You can find this log again with our other commercial roofing resources for building owners.

What to Write in Each Column

Write only plain facts in every leak log column, and put "unknown" instead of guessing or leaving a blank. The location, history, leak and photo columns follow a published roof record form for school buildings. That form also covers rooftop checks, which this log leaves to a roofer.

• Incident ID: A short code, such as a building initial plus a number.
• Observed date/time/time zone: When the water first appeared and last looked active. Add PT for Pacific Time.
• Interior area: A unique building or site code, then floor, room or corridor and a landmark.
• Observer role / permitted contact: A role, such as front desk, plus a contact route the person agreed to share.
• What was seen: Plain facts, such as a drip, a stain or wet carpet. No guesses about the cause.
• Safely taken photo/file reference: File names for photos you took from the floor, or "none."
• Known prior incident or work reference: Earlier IDs, or a known repair with its date and who did it.
• Official weather lookup and station/time context: The weather note from the next section, or "not checked."
• Manager notified / follow-up owner: Who got the report, when and how, and who owns the next step.
• Contractor findings recorded separately: The roofer's written findings, with company name and date. Never edit the original sighting notes.
• Open/closed status and evidence: Open until the follow-up owner records a dated closure decision and the evidence behind it. A repair invoice alone cannot confirm that the leak stopped.

Weather data adds context to a leak row, but it only describes conditions at a weather station. It cannot show what fell on your roof or why water came inside. For past hourly readings and links to climate records, use the National Weather Service Los Angeles/Oxnard historical observations page.

For a site in Los Angeles or elsewhere in Los Angeles County, California, choose the closest station.

Put these details in the weather column:

• the page address you used
• the station name or ID the page shows
• the date and hours you checked
• whether times appear in local time or UTC
• the units the page shows
• the station's reported values, exactly as the page lists them
• the date you looked it up

Write "no data" if the station shows nothing for your hours. Write "unknown" if no station fits or the hours miss your sighting. Never add storm totals from news stories or memory.

A station reading describes the spot where the station stands. Rain there does not prove rain fell on your roof or caused the leak. A dry reading does not prove your roof stayed dry, either.

This made-up entry shows how front desk staff record one corridor stain and report it to the building manager. It describes no real building, person or project. The entry names no cause, makes no guess about rain and notes only what staff observed from the floor.

Later, the roofer's written findings belong in the contractor column, while the front desk's stain note stays unchanged. If the stain spreads, the manager adds EXAMPLE-02, linked to EXAMPLE-01 without naming a cause.

Give the roofer every leak log row, photo and repair record for the affected area in one package. A stain inside does not prove where water gets through the roof. Your log still gives our commercial roof repair team the where, when and how often of the leak.

Include the following records:

• every row for the affected area, open and closed
• photos with file names that match their incident IDs
• repair or reroof records you hold, with dates
• the name of the person who can arrange roof access
• the follow-up owner and how to reach them

Call (424) 842-2249 to report the leak and set up a free repair estimate.

Some owners also need a written record of the roof's condition. We provide that through a commercial roof inspection with a detailed written report, which is a separate paid service. Your leak log can support that work, but it does not become the report.

We handle commercial roofing in Los Angeles, from leak repair to full roof replacement.
