For Roofing Manufacturers
The Roofing Book gives roofing manufacturers an authoritative, structured listing — 314 manufacturers and 4383 products today — rendered as machine-readable Schema.org that AI answer engines and search crawlers can cite.
A structured listing built to be cited
Each product renders as Schema.org Product / ProductModel and each manufacturer as Organization / Brand, baked into server-rendered HTML — so crawlers and answer engines that read raw HTML see the full structured record. Manufacturer records carry a sameAs link to your official site so engines reconcile your brand identity correctly.
Provenance that earns trust
Product specs — wind and impact classes, fire rating, warranty terms, standards met — are each cited and dated. That per-field provenance is the exact signal search and answer engines use to decide what is trustworthy enough to quote. Your accurate spec, sourced and dated, is far more citable than an unsourced marketing claim.
Keep your listing accurate
Every manufacturer page carries a "claim this profile / suggest an edit" link so you can flag a discontinued product, a superseded line, or a corrected spec. Corrections are verified against a source and dated on publish.
How sponsored listings work
The reference data in this book is sourced, and it is not for sale. A sponsored listing is a separate, paid placement with its own rules:
- Labeled. Every sponsored placement carries the word "Sponsored" and sits in its own panel, apart from the sourced records. It has no verification badge, because the book has not verified it.
- Placement only. Payment does not change, reorder or remove any sourced record, and it does not change what the book says about a code, a product or a jurisdiction.
- Kept out of the data. Sponsored content is left out of the structured data, the AI-readable index and Supplement Packs. An answer engine citing this book is never citing an ad.
- Identity checked. The one thing checked is that the request comes from the company's own domain. The wording in a placement is the sponsor's.
Sponsored placements are not live yet. The form below registers interest and goes to a person.
