HazCom for Roofing Contractors: Why Almost Every Citation Is Serious
Roofing contractors are cited less often than machine shops or stone fabricators in our dataset of federal OSHA Hazard Communication citations — 12 of 138. But of those twelve, ten were classified Serious. That is the highest share of any trade with ten or more citations in our data.
1. What the citation data shows
We track federal OSHA HazCom citations and publish them in our citation tracker. Filtering to NAICS 238160 (Roofing Contractors) for citations issued between January 2025 and March 2026 gives 12 citations, seven of them in Florida, three in Missouri and two in Texas.
By paragraph of 29 CFR 1910.1200:
| Paragraph | Subject | Citations |
|---|---|---|
| (e) | Written hazard communication program | 6 |
| (g) | Safety data sheets | 3 |
| (h) | Employee information and training | 3 |
Half were for having no written program. As in most trades in our data, labelling was not what got roofers written up.
2. The problem is that the workplace moves
Every other trade we have looked at has a fixed shop. Roofing does not. The chemicals travel on the truck, the crew changes between jobs, and the office where the paperwork lives is nowhere near the roof.
That is the practical reason this trade struggles with paragraphs (e), (g) and (h) rather than labelling: a written program in a filing cabinet at the yard, safety data sheets on a shelf that no one on the roof can reach, and training records for a crew that has turned over since the last project. None of those failures are visible on site, which is exactly why they get cited.
3. What roofers actually carry
- Solvent-based adhesives, mastics and lap cements
- Primers and bonding adhesives for single-ply membranes
- Hot-applied bitumen and its solvent thinners
- Roof coatings, whether acrylic, silicone or asphalt-based
- Sealants, caulks and their catalysts
- Cleaners and solvents used to prepare a surface before bonding
Whether a specific product is covered depends on the definitions and exclusions in paragraph (b), which is also where the labelling exemption for certain consumer products sits, at (b)(5)(v).
4. Training when the crew changes
Paragraph (h) covers employee information and training. The standard requires it “at the time of their initial assignment, and whenever a new chemical hazard the employees have not previously been trained about is introduced into their work area”.
The second trigger matters too, and it fires more often in roofing than in a fixed shop. A different membrane system means a different adhesive chemistry, and that is a new hazard for a crew that has never used it.
5. Making a written program work off a truck
Paragraph (e) requires a written hazard communication program. Nothing in it says the program has to sit in one building. For a mobile trade the workable version is a copy that travels: the program itself, the current list of what is on the truck, and the sheets for those products, kept together and reachable by the crew rather than by the office.
This is the most-cited item in this trade and across our whole dataset, and it is the one that costs nothing but the writing.
6. A realistic order of work
- Write the program, and write it for a crew that is not at the yard.
- Put a copy, plus the sheets, in each truck — paper or on a phone, so long as the crew can open it.
- Train new hires before their first job, and record it.
- When a system or supplier changes, treat it as a new hazard and cover it.
- Keep the truck list current, because the inventory is whatever is on board today.
Frequently asked questions
What do roofing contractors get cited for under OSHA HazCom?
In our dataset of federal HazCom citations issued to NAICS 238160 employers between January 2025 and March 2026, 6 of 12 were for the written hazard communication program (paragraph (e)), 3 for safety data sheets (paragraph (g)) and 3 for employee information and training (paragraph (h)). Ten of the twelve were classified Serious.
Do safety data sheets have to be at the job site, or is the office enough?
Paragraph (g) is about employees having access to the sheets for the chemicals they work with. For a mobile trade the practical test is whether the crew on the roof can reach the sheet for what they are applying, rather than whether a copy exists back at the yard.
Does a roofing crew need HazCom training every year?
The word “annual” does not appear in 29 CFR 1910.1200. Training is required at the time of an employee’s initial assignment, and whenever a new chemical hazard they have not previously been trained about is introduced into their work area — for example moving to a membrane system with a different adhesive chemistry.
Can the written program live at the office if the work is on site?
Nothing in paragraph (e) requires the program to sit in one building, but it must be a real program describing how the company handles labels, safety data sheets and training. For a mobile crew the workable version is a copy that travels with the truck alongside the current product list.

Most SDS software stops at the safety data sheets. OSHA HazCom asks an employer for five things: a written program, a chemical list, container labels, SDS access and employee training. SDSentry covers all five in one product and builds the written program from your own chemical list. See how 11 SDS tools compare on all five →
