How to Write a Hood Cleaning Inspection Report Customers Actually Understand

A hood cleaning inspection report is a written record that documents the condition of a commercial kitchen's exhaust system before and after service — including grease accumulation levels, deficiencies found, work performed, and compliance status. Done right, it takes 10–15 minutes to complete, protects you from liability disputes, and gives restaurant owners the documentation their fire marshal or insurer may require.

Most technicians skip the report or hand over a vague one-liner that says "cleaned hood system." That's a missed opportunity. A well-structured report is the single best tool you have for justifying your price, getting re-signed on a service contract, and standing out on professionalism alone — before a customer even compares quotes.

What Should a Hood Cleaning Inspection Report Include?

A complete hood cleaning inspection report covers six core areas: site and system identification, pre-cleaning grease levels, deficiencies found, work performed, post-cleaning condition, and compliance or recommendation notes. Each section serves a distinct purpose and should stand on its own — a fire marshal or insurance adjuster may read only one section.

1. Site and System Identification

Start with the basics so there's zero ambiguity:

• Business name, address, and contact name
• Date and time of service
• Technician name and (if applicable) certification number
• System description: hood type (Type I or Type II), make/model of fan, duct configuration, number of filters, access panel locations
• Frequency of service (e.g., quarterly, semi-annual) and date of last service

This header turns a report into a legal record. If a fire ever damages the kitchen, this section proves you were there and what system you serviced.

2. Pre-Cleaning Grease Accumulation Levels

This is where most reports fall apart. "Heavy grease buildup" means nothing to a restaurant owner — or a fire marshal. Use a standardized scale. The most commonly referenced benchmark in the industry comes from NFPA 96, the Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations, which is the code most jurisdictions adopt. NFPA 96 describes grease accumulation in terms of depth and location.

A practical field scale looks like this:

| Level | Description | Typical Depth |

|-------|-------------|---------------|

| 1 – Light | Thin film, easily wiped | Under 1/16" |

| 2 – Moderate | Visible coating, some pooling | 1/16" – 1/8" |

| 3 – Heavy | Thick deposits, dripping risk | 1/8" – 1/4" |

| 4 – Critical | Carbonized buildup, fire hazard | Over 1/4" |

Document the level at each location: the hood plenum, the duct interior (top, middle, bottom if accessible), the exhaust fan housing, and any grease troughs or drip cups. A photo paired with each entry is worth more than a paragraph of description — use your phone and attach images to the report.

3. Deficiencies Found

List every issue you observe, even ones you can't fix yourself. This protects you from being blamed for pre-existing problems later. Common deficiencies to document:

• Missing or damaged baffle filters
• Grease cup overflowing or missing entirely
• Damaged or unsealed access panels
• Fan belt wear or motor issues
• Ductwork gaps, holes, or unsealed joints
• No make-up air (common and a fire risk)
• Suppression system nozzles blocked by grease
• Missing or expired suppression system inspection tag

Write each deficiency in plain language: "Grease cup on east side fan was missing — grease dripping onto roof surface." Not "deficiency noted at exhaust unit." If it's a code violation or a safety concern, say so explicitly. Customers take action on specific, clear language.

4. Work Performed

Document exactly what your team did:

• Surfaces cleaned and method used (hand scraping, hot water pressure wash, chemical degreaser — specify product if relevant)
• Areas that could NOT be fully accessed and why (document this carefully — it limits your liability)
• Filters removed, cleaned, and reinstalled or replaced
• Grease cups emptied and cleaned
• Fan blades cleaned
• Any repairs made

If a section of duct was inaccessible without an additional access panel (a common upsell opportunity), note that in writing and explain the risk of leaving it uncleaned. This sets up a natural follow-up conversation — not a hard sell, just documentation that gives the customer a clear reason to act.

5. Post-Cleaning Condition

Use the same grease accumulation scale from section 2 and document the post-service level at each location. This before/after comparison is the most powerful trust-builder in the report — it shows the customer exactly what they paid for.

Include a note on overall system condition: "System cleaned to bare metal on all accessible surfaces. Recommend quarterly service given high-volume fryer operation."

6. Compliance Notes and Recommendations

This section is brief but important. State whether the system, based on your inspection, appears to meet the service frequency requirements for the type of cooking operation — and note that final compliance determination rests with the local authority having jurisdiction (AHJ). Never certify code compliance yourself unless you're licensed to do so in your state. In many jurisdictions, only a certified inspector or fire official can make that determination.

List any recommendations with urgency levels:

• Immediate (safety risk): Grease cup missing, suppression nozzles blocked
• Within 30 days: Access panel needs resealing, filter damage
• At next service: Fan belt showing wear

How Do You Format the Report So Customers Actually Read It?

Keep it to one or two pages. Use checkboxes and a table for the grease levels — walls of text get skimmed and ignored. A photo page can be a third page.

A simple layout works well for most operators:

• Page 1: Header info, pre/post grease level table, deficiencies checklist
• Page 2: Work performed, compliance notes, recommendations, technician signature
• Photo attachment: Numbered photos keyed to the deficiency list

PDF is the right format. Email it the same day as service — ideally within an hour of leaving the job. Same-day delivery signals professionalism and keeps the report attached to a fresh memory of your work.

For operators managing multiple recurring accounts, a field service app that captures photos and auto-generates the PDF on-site removes nearly all the friction from this step. The goal is a format you can complete consistently on every job without it feeling like extra paperwork.

How Does the Report Justify Your Invoice?

A detailed report turns your invoice from a number into a story. When a restaurant owner sees "Level 4 – Critical grease accumulation (1/4"+ depth) in duct interior, reduced to Level 1 post-service," they understand why they paid what they paid.

This matters most when you're charging rates at the higher end of the typical range — and those ranges vary meaningfully by region, with metro markets often running 30–50% above rural rates. For context on how hood cleaning is priced, see Hood Cleaning Rates by Kitchen Type: A Complete Rate Guide and How to Price Hood Cleaning Jobs: A Flat-Rate vs. Hourly Breakdown — both break down how job complexity, kitchen type, and service frequency affect what you should charge.

A report that documents a Level 4 duct condition and a missing suppression nozzle also sets up an honest conversation about more frequent service — and that's a contract renewal, not a sales pitch.

What's the Fastest Way to Build a Report Template?

Build a fillable PDF or use a field service app that lets you add photos and checkboxes on-site. At minimum, your template needs:

• Pre-built grease level scale (just circle or check the level at each location)
• Deficiency checklist with a blank field for notes
• Work performed section with standard line items you can check off
• Photo attachment section
• Signature field for the technician

Spend 90 minutes building this once and you'll use it on every job. A consistent format also makes it easier for your customers' managers and accountants to file the reports for their own compliance records — which means they'll actually keep them, and keep calling you.

Frequently Asked Questions

Q: Is a hood cleaning inspection report legally required?

A: Requirements vary by jurisdiction. Many local fire codes and health departments require documentation of hood cleaning service — and some require it to be available on-site for inspection. Check with your local authority having jurisdiction (AHJ) and your state fire marshal's office to confirm what's required in your market. NFPA 96 is the baseline standard adopted in many areas.

Q: How long should I keep copies of completed inspection reports?

A: Industry best practice is to retain reports for at least three years, though some jurisdictions require longer. Keep a digital copy and offer your customer a copy for their own files. Both parties having records protects both parties.

Q: What grease accumulation level is considered a fire hazard?

A: Generally, grease deposits exceeding 1/8" to 1/4" in depth — particularly in duct interiors — are considered a significant fire risk and may trigger a re-clean requirement under NFPA 96 guidance. A Level 3 or Level 4 condition on the field scale above warrants immediate attention and should be clearly flagged in your report.

Q: Should I document areas I couldn't access?

A: Yes, always. Documenting inaccessible areas protects you from liability if a fire originates in a section you couldn't reach. Note the reason (no access panel, equipment in the way) and recommend remediation so the customer understands the risk.

Q: Can I use my inspection report to upsell additional services?

A: Absolutely — and it's more effective than a verbal pitch. A documented deficiency with a clear explanation of the risk gives the customer a reason to act. If a suppression nozzle is blocked or a duct section is uncleaned, the report creates a natural, non-pushy path to scheduling a follow-up.
