Natural slate or roof tiles: criteria to compare
Published on 31 July 2026 · Verified on 18 September 2026 · The Mestravaux.lu team
The choice is not simply durable slate versus economical tile. Appearance, geometry, support, fixings and junctions must suit the building. Compare exact products and installation, then supply-and-fit offers.
The essentials in 30 seconds
- Confirm appearance constraints before ordering.
- Check model suitability for slope and exposure.
- Compare whole-system load rather than one piece.
- Ask about junctions, replacement parts and upkeep.
- Lifespan and cost rankings are not universal.

Start with the building’s options
Present material, colour and appearance to the municipality. Guichet.lu explains the relationship with applicable planning rules. An old-town location or grand house alone does not establish a slate requirement; confirm the exact rule and heritage constraints.
| Critère | Ardoise naturelle | Tuile terre cuite | Tuile béton |
|---|---|---|---|
| Prix posé au m² | 180 – 320 € | 140 – 200 € | 120 – 160 € |
| Durée de vie | 80 – 100 ans | 50 – 70 ans | 30 – 50 ans |
| Poids au m² | 40 – 50 kg | 45 – 55 kg | 45 – 60 kg |
| Entretien | Quasi nul | Limité | Hydrofuge après 15-20 ans |

Connect format, slope and exposure
CUPA describes overlap depending on slope, site, water run and fixing. Wienerberger’s Standard S slope information also depends on installation conditions. An isolated figure is not universal; have the actual solution confirmed professionally.
Compare actual added load
Request installed load per area with piece count, overlap and associated components. Add planned insulation or equipment. A lighter piece or material name alone does not establish structural suitability; assess the complete assembly.
Inspect appearance and details
Compare samples, sizes, colour variation, edges, ridges and junctions. Natural slate, clay tile and concrete tile are not interchangeable references. Request exact product and accessories for your roof forms.
Your project deserves an accurate estimate — it's free.
Request a quotePlan upkeep and repair
Ask about inspection, professional access and compatible spares. No material removes the need to check fixings, drains and junctions. Do not automatically schedule coatings, aggressive cleaning or replacement at a generic age.
Compare without a universal ranking
Match supply, fitting, support, adaptation, access, removal and junctions. Separate product warranty from actual whole-roof behaviour. Without suitable evidence, no price gap, doubled life or universal best compromise is established.
Frequently asked questions
Is slate compulsory throughout Luxembourg?
Not as a general rule. Check requirements for the plot and building.
Does every tile suit every slope?
No. Assess model, installation, exposure and project requirements.
Is slate always lighter?
Compare complete installed load at defined overlap and components.
Are tiles necessarily cheaper?
Only equivalent quotes including adaptations can answer for the project.
Which material needs no upkeep?
Do not accept that promise for an entire roof. Ask about appropriate checks and interventions.
