What is stone-coated steel roofing?
Stone-coated steel is a steel roof panel coated to resist rust, then covered with stone granules bonded to the surface. The panels are pressed into shake, tile, shingle or barrel shapes. From the street it looks like a traditional roof, but it is a metal roof that weighs far less than clay or concrete tile.
Because the panels overlap rather than run in one piece from eave to ridge, stone-coated steel behaves differently from standing seam. Our metal roofing hub compares the two at a glance.
Is stone-coated steel right for your home?
It fits homeowners who want a metal roof’s durability with a traditional look, often in neighborhoods or HOAs that discourage exposed-seam metal. It is also a common replacement for heavy tile on framing that was not built for it. It costs more up front than asphalt shingles, so it suits owners staying long term.
When we’d steer you elsewhere
If you want the lowest price for a short stay in the home, a Class 4 asphalt shingle may make more sense. If you want a clean modern look or have a very low slope, standing seam may fit better. We price the options side by side on the same measurements so you can compare.
How does stone-coated steel hold up to DFW hail?
Hail is a major reason North Texas owners choose it. DECRA, for example, lists its stone-coated products as UL 2218 Class 4 and on the Texas Department of Insurance list of products qualifying for impact-resistant roofing credits. Large hail can still knock granules loose and dent panels, so have the roof inspected after storms.
Ratings belong to the tested product, not to the roofer. Here is what one maker publishes for its line, as an example of the paperwork to ask for:
| Item | What DECRA publishes |
|---|---|
| Hail rating | UL 2218 Class 4 |
| Fire rating | UL 790 Class A |
| Wind uplift | UL 580 / UL 1897 Class 90 |
| Texas listings | TDI impact-resistant credit list; TDI wind reports RC-281, RC-282, RC-235 and RC-548 |
| Code evaluation | ICC-ES ESR-2901 (on battens) and ESR-1754 (direct to deck) |
| Profiles named | Tile, Villa Tile, Shake, Shake XD, Shingle Plus, Shingle XD |

We install stone-coated steel from DECRA and other makers. Whichever product you choose, ask for its impact, fire and wind reports and check that your insurer accepts them.
How is stone-coated steel installed?
Depending on the product, panels go on wood battens or straight onto the roof deck, over underlayment, with fasteners through the panel overlaps. Trim covers ridges, hips, rakes and valleys, and flashing seals walls, chimneys and pipes. Check the maker’s minimum slope; the code minimum for metal roof shingles is 3:12.
That code minimum comes from the 2021 International Residential Code (§R905.4.2). The maker’s own limit for the exact profile governs if it is stricter. Battens add an air space under the panels; direct-to-deck installs sit lower. Your written scope should say which method the product calls for.
Stone-coated steel vs standing seam vs tile
Stone-coated steel gives a traditional look with metal’s light weight and hail ratings. Standing seam gives a clean modern look and suits lower slopes. Clay or concrete tile is the heaviest and needs framing built for it. Ratings belong to specific products, so compare the exact systems quoted, not categories.
| Stone-coated steel | Standing seam | Clay or concrete tile | |
|---|---|---|---|
| Look | Shake, tile, shingle | Smooth panels, raised seams | Barrel, flat, low-profile tile |
| Code minimum slope (2021 IRC) | 3:12 (metal roof shingles, §R905.4.2) | ¼:12 (§R905.10.2) | 2½:12 (§R905.3.2) |
| Hail rating | Many products UL 2218 Class 4 (check product) | Belongs to the tested assembly | Varies by profile (check product) |
| Weight | Light (check the maker’s data) | Light | Heavy; 9 lb per sq ft or more installed is “standard weight,” per the Tile Roofing Industry Alliance |

Repairs and care
Usually a damaged panel can be repaired. Single panels can be lifted and replaced because panels overlap rather than lock along the full roof. Matching color on an older roof can be harder, so keep a few leftover panels from your install. Ask the maker which touch-up products it offers for small areas of granule loss.
For care, walk only where the maker says, keep valleys and gutters clear because granules wash into gutters over time, and have the roof checked after major hail. Avoid pressure-washing the surface, which can strip granules. If hail has already hit, see our storm damage page.
