# Roofing Directory > A structured, provenance-disciplined reference of 147 sourced roofing records across six entity types — materials, products, manufacturers, suppliers, trade organizations, and Denver-metro permitting authorities — plus in-depth guides and per-city hubs. Every field carries a cited source URL and a verification date. The Roofing Directory is a reference asset, not a lead-generation site. Pages are server-rendered HTML with Schema.org JSON-LD baked into the initial response, so the content and structured data are visible without executing JavaScript. Static facts inherit each record's entity-level source and date; volatile facts (warranties, hours, permit rules) carry their own field-level citation. Records pass an 8-pass validation gate before publishing. See the methodology page for the full sourcing discipline. Last verified content dates up to 2026-07-12. ## Core reference - [Roofing materials (23)](https://roofing-directory.pages.dev/materials/): Material categories with lifespan, wind/impact/fire ratings, cost band, and slope suitability. - [Roofing products (42)](https://roofing-directory.pages.dev/products/): Named product lines with ratings, warranty terms, and the standards they meet. - [Manufacturers (22)](https://roofing-directory.pages.dev/manufacturers/): Roofing manufacturers, their product lines, and certification programs. - [Suppliers & distributors (5)](https://roofing-directory.pages.dev/suppliers/): Distributors and supply houses with their Denver-metro / Front Range branches. - [Trade organizations (9)](https://roofing-directory.pages.dev/trade_orgs/): National and regional roofing trade associations and standards bodies. - [Permitting authorities (46)](https://roofing-directory.pages.dev/permitting_authorities/): Colorado jurisdictions: roofing permit and contractor-registration requirements. ## Browse by attribute & city - [Roofing materials by attribute](https://roofing-directory.pages.dev/materials-by/): Class 4 impact-resistant, by slope, by material family, and Class A fire-rated. - [Roofing suppliers by city](https://roofing-directory.pages.dev/suppliers-by-city/): Distributors and supply houses by their Denver-metro and Front Range branch cities. ## Guides & glossary - [Roofing guides (index)](https://roofing-directory.pages.dev/guides/): In-depth, sourced guides for homeowners and contractors. - [Class 4 Impact-Resistant Shingles in Colorado: A Buyer's Guide](https://roofing-directory.pages.dev/guides/class-4-impact-resistant-shingles-colorado/): What UL 2218 Class 4 actually means, why impact-resistant shingles matter on the Colorado Front Range hail belt, and the real Class 4 products tracked in this directory. - [How to File a Roof Insurance Claim After Hail (Colorado)](https://roofing-directory.pages.dev/guides/roof-insurance-claim-after-hail-colorado/): A step-by-step Colorado roof hail-claim walkthrough, including the state consumer-protection statutes (C.R.S. title 6, article 22) that govern roofing contracts, deductibles, and your right to rescind. - [Roofing Permit Requirements Across Denver Metro](https://roofing-directory.pages.dev/guides/denver-metro-roofing-permit-requirements/): How roofing permits and contractor licensing work across Denver-metro and Front Range jurisdictions — no statewide license, locally adopted I-Codes, and a directory of the real permitting authorities. - [Asphalt vs. Metal vs. Tile: A Colorado Roofing Material Comparison](https://roofing-directory.pages.dev/guides/asphalt-metal-tile-roofing-comparison-colorado/): A side-by-side comparison of asphalt, metal, and tile roofing — service life, weight, cost band, and hail behavior — using the sourced material data in this directory, framed for Colorado conditions. - [What Does a New Roof Cost in Colorado?](https://roofing-directory.pages.dev/guides/new-roof-cost-colorado/): How to think about roof-replacement cost in Colorado using relative material cost bands and the real drivers of a bid — framed as estimates, not fabricated prices, so you can compare quotes intelligently. - [Roofing Wind & Fire Ratings Explained (ASTM D3161 / D7158, UL 790)](https://roofing-directory.pages.dev/guides/roofing-wind-and-fire-ratings-explained/): A plain-language explainer of the roofing performance standards behind the specs — wind (ASTM D3161 and D7158), fire (UL 790 / ASTM E108), and impact (UL 2218) — with the real rated products in this directory. - [Roofing glossary](https://roofing-directory.pages.dev/glossary/): Plain-language definitions of common roofing terms. ## For business - [For contractors](https://roofing-directory.pages.dev/for-contractors/): Neutral sourced spec + local permitting reference. - [For manufacturers](https://roofing-directory.pages.dev/for-manufacturers/): Authoritative, structured, citable product listings. - [For suppliers](https://roofing-directory.pages.dev/for-suppliers/): Branch-level local discovery via per-city hubs. ## About - [Methodology & Sourcing](https://roofing-directory.pages.dev/methodology/): Provenance model, the 8-pass validation pipeline, and why the data is citable. ## Per-city hubs - [Roofing by city (37 cities)](https://roofing-directory.pages.dev/roofing/): Each hub aggregates a city’s permit rules, local suppliers, and hail-appropriate materials. ## Optional - [Sitemap (XML)](https://roofing-directory.pages.dev/sitemap.xml): Every crawlable URL. - [robots.txt](https://roofing-directory.pages.dev/robots.txt): Crawl policy — AI answer-engine crawlers explicitly welcomed.
