Roofing shingle product attributes

Asphalt shingles are bought by the square but sold by the bundle, and the conversion depends on shingle size and exposure. Supplier titles usually say three bundles per square, yet metric-size and English-size shingles cover different areas per bundle. Without exposure, coverage and bundles per square as numbers, takeoff tools and online calculators produce the wrong order quantity.

Performance ratings come from different test methods that suppliers mix freely. Wind resistance can be reported under a fan-driven test or an uplift-based classification, and warranty wind speeds are a separate commercial term that depends on nailing and accessories. Impact classes, fire classes and SBS modification are often stated on a brochure but missing from the item file.

In high-wind and hurricane-prone regions, the sale also depends on a current product approval number from the state or county. Those approvals carry revision numbers and expiration dates. Recording profile, color, dimensions, coverage, rating classes and approvals per SKU keeps a roofing distributor's quotes defensible when the building department or insurer asks.

The roofing shingles attribute template

18 candidate fields in 4 groups, ordered the way a record gets built: identify the item, capture its specifications, then record fit and the evidence behind any claim. 9 are marked Core: without them the item cannot be identified or filtered. Example values show the expected format only; they do not describe a real SKU.

Identity

Which exact item, variant and pack this record describes.

Check before use: Preserve leading zeros and punctuation, validate against the manufacturer record, and check the GTIN check digit and packaging level before linking.

Attribute	Type	Priority	Example format
Manufacturer Part Number manufacturer_part_number	Identifier	Core	SH-LAM-30-CHR
Brand & Product Line brand_product_line	Text	Core	Example Brand Laminated 30
Bundles per Square bundles_per_square	Number	Core	3
GTIN / UPC gtin_upc	Identifier	Core	00614141370061

Technical specifications

Measured or rated values that must travel with their unit and test conditions.

Check before use: Store the number and unit separately. Convert only when the source unit and test conditions are known.

Attribute	Type	Priority	Example format
Exposure exposure	Number · in	Core	5-5/8
Coverage per Bundle coverage_per_bundle	Number · ft²	Core	33.33
Nominal Shingle Size (W x L) nominal_shingle_size_w_x_l	Text · in	Core	13-1/4 x 39-3/8
Enhanced-Nailing Fastener Count enhanced_nailing_fastener_count	Number	Buyer decision	6

Selection attributes

The type, material and option choices buyers filter and compare on.

Check before use: Map supplier wording to a governed vocabulary only after checking the source text and which variant it applies to.

Attribute	Type	Priority	Example format
Shingle Profile shingle_profile	Controlled list	Core	Laminated (architectural)
Color Name color_name	Text	Core	Charcoal
Asphalt Modification Type asphalt_modification_type	Controlled list	Buyer decision	SBS polymer-modified

Evidence & compliance

Listings, standards, classifications and origin claims that need a document behind them.

Check before use: Link the manufacturer document or label with its edition or date. Never copy a certification from a neighboring SKU.

Attribute	Type	Priority	Example format
Wind Warranty Speed wind_warranty_speed	Number · mph	Buyer decision	130
Algae Resistance Warranty Term algae_resistance_warranty_term	Number · yr	Buyer decision	25
Limited Warranty Term limited_warranty_term	Controlled list	Buyer decision	Lifetime Limited
Fire Resistance Class fire_resistance_class	Controlled list	Channel / evidence	Class A (ASTM E108 / UL 790)
Wind Resistance Classification wind_resistance_classification	Controlled list	Channel / evidence	Class H (ASTM D7158)
Impact Resistance Class impact_resistance_class	Controlled list	Channel / evidence	Class 4 (UL 2218)
Code Approval Numbers + Expiry code_approval_numbers_expiry	Text	Channel / evidence	State approval FL00000-R0, expires 2028-06-30

Normalize supplier values

The same value arrives in many spellings. Map each raw string to one governed value, and keep the raw text beside it so a reviewer can see what the supplier actually wrote.

Often missing from supplier files

These fields are commonly absent from price lists and basic feeds, even though the information usually exists in a datasheet, label or installation manual. Treat an empty value as a request for evidence, not as permission to fill it from a similar model.

• Wind Resistance Classification (ASTM D7158)
• State / County Product Approval Number and Expiration
• Aged Solar Reflectance and Thermal Emittance
• Asphalt Modification Type (SBS vs oxidized)
• Exposure and Coverage per Bundle as numbers

Questions the record must answer

Buyers and counter-sales reps choosing roofing shingles ask questions like these. Each one needs a specific field, sourced for the exact variant.

• How many bundles do I need to cover a 30-square roof?
• Does it meet the high-wind classification our county requires?
• Is it Class 4 impact rated for the homeowner's insurance paperwork?
• Does the higher wind warranty require six nails per shingle?

From supplier file to record

1. Resolve identity first. Link the supplier SKU, manufacturer part number and packaging identifiers without merging distinct variants or pack sizes.
2. Extract with the source attached. Pull values from rows, tables and datasheets, keeping the raw text, unit and page or row reference.
3. Map to your classification. Assign the ETIM, ECLASS, UNSPSC or internal class your company licenses, and keep the supplier's original terms.
4. Review, sync and watch. Hold conflicts and safety-related values for a category expert, write approved values to ERP or PIM, and recheck when the supplier sends a new file.
