16,558 roofing contractors certified under this manufacturer's program, with street address, phone, website, coordinates and the exact certification tier each holds. CertainTeed's ShingleMaster and SELECT ShingleMaster credentials require documented training and workmanship standards. Certification is the most reliable quality filter available in a trade with very low barriers to entry, which is why distributors, insurers, lead generators and acquirers all use it to qualify. Refreshed weekly from the manufacturer's own contractor locator, so newly certified and lapsed contractors move in and out rather than the list quietly going stale.

The file has all 16,558 locations across 51 states in one download. Building the same list by searching one area at a time tends to miss places, and a missed place looks like a gap in coverage that is not really there.

## Questions

### What does the certification actually require?

Broadly: proof of licensing and insurance, a workmanship track record, and training. The specifics differ by manufacturer and tier, but in every case it filters out the uninsured and transient operators that make roofing a difficult trade to prospect.

### Do these contractors work exclusively with this manufacturer?

Rarely. Most certified roofers hold credentials from several manufacturers, which is why our combined roofing dataset accumulates every certification onto one row and gives you a certification count.

### How current is it?

File built on October 18, 2026. Rebuilt weekly on an automatic schedule. The date on this page is the date of the file you would download.

### How is this data cleaned?

Every rebuild runs the same steps and counts what each one changed. For the current file, rebuilt October 18, 2026 from certainteed.com: Merged 0 duplicate listings that had the same business name, street address and ZIP code, keeping every filled-in detail from both (October 18, 2026). Unified 295 city names written more than one way within the same ZIP code (for example with and without a space or an abbreviation) to the US Census Bureau spelling (October 18, 2026). Corrected 26 misspelled city names to the US Census Bureau place name for their ZIP code (October 18, 2026). Set the state on 3 listings to its two-letter US Postal Service code, matched to the US Census Bureau state register (or, for Canadian rows, the ISO province code) (October 18, 2026). Shortened 383 ZIP codes to the five-digit code every address filter expects, keeping the delivery-route segment in a column of its own (October 18, 2026). Removed the second copy of 17 street addresses that were typed twice in the same field (October 18, 2026). Added map coordinates to 0 listings that had none, from the US Census Bureau address geocoder or, where the street address could not be matched, the centre of the ZIP code (October 18, 2026). Set the county and its federal county code on 15,437 listings, matched to the US Census Bureau county list from the county the source records, the listing's map point, or its ZIP code area (October 18, 2026). Checked every map point against the state in its address and re-placed 14 points that fell outside that state (October 18, 2026). Flagged 821 addresses that are incomplete, a PO box, or missing a house number, in an address quality column (October 18, 2026). Checked that the row count, state count and field completeness published for this file were measured from the file itself (October 18, 2026).

### Isn't this free on certainteed.com?

The underlying records are public on certainteed.com. What you pay for is the work between that public release and this file: unified 295 city spellings, corrected 26 misspelled city names, standardised 3 state codes, shortened 383 ZIP codes, fixed 17 doubled addresses, added the county to 15,437 listings, re-placed 14 misplaced map points, flagged 821 incomplete addresses and measured 16,558 rows, and a fresh rebuild every week. The current file was rebuilt October 18, 2026 from certainteed.com. Doing it yourself means downloading the full release, repeating each of those steps, and repeating them again every time the source updates.

### How complete is each field?

Measured on every row of the current file, the share of rows that carry each key field: phone 100%, website 77%, street address 100%, city 100%, state 100%, ZIP code 100%, latitude 100%, longitude 100%. 18 of 20 columns are filled on at least half the rows.
