AI for roofing supply distributors, tested on roof packages and job accounts you already closed.

This is a wholesale trade with its own line in the federal code. NAICS 423330 covers establishments primarily engaged in the merchant wholesale distribution of nonwood roofing and nonwood siding and insulation materials. A low-slope desk sells membrane, polyiso, fasteners, adhesive and flashing as one assembly per roof. Each closed quote left a spec, a plan, a takeoff and the lines your team chose, so a draft can be graded against work already done.

A product standard stops at the product. The public abstract for ASTM D4434, the standard specification for poly(vinyl chloride) sheet roofing, puts fire resistance, material compatibility, wind uplift and in-place shrinkage outside its scope. A line citing it says nothing about the insulation and adhesive quoted next to it. Insulation carries its own code: ASTM C1289 sorts faced polyisocyanurate board into five types, with classes and grades inside some of them. Reading those pieces together is the skill your desk has, and the thing worth testing.

Some lines are regulated at the point of sale. South Coast AQMD Rule 1168, last amended November 4, 2022, reaches anyone who sells, stores, supplies or distributes a covered product above its VOC limit, not only the crew that applies it, and it gives EPDM and TPO single ply roof membrane adhesive a line of its own at 250 grams per liter. Where the building sits can decide which adhesive belongs on the quote, so the draft notes each job's location beside its adhesive lines for a person to check.

The spec reaches into delivery and timing. Texas State University's roof insulation standard for its Round Rock campus bars insulation and cover board from sitting on the roof overnight, wants them in a covered storage trailer, and has each day's allotment loaded up and used that day. It also says materials ordered before written approval of submittals are ordered at the contractor's risk. A package quoted as one drop may not be the package that job can accept.

Notices run on state clocks, and not all of them go to the owner. Utah has suppliers file a preliminary notice on its State Construction Registry, within 20 days of beginning work on the property according to the state's own page, and property owners can look up who has filed. Other states route the same idea through the mail or a recorded notice of commencement. Your credit team already worked that out for every job account it opened, which makes a job sheet and its notice list a fair test too.

What neither test does. Neither one touches your ERP, your credit system or a live quote, and nothing gets sent or filed. No draft says a roof system qualifies for a manufacturer's warranty, and none decides what a lien statute requires. A person checks every quote, and your credit manager or counsel decides every notice. Notice rules vary by state and they change, so this is a drafting test, not legal advice.
