Střecha na klíč / Roofing and its replacement
Roofing materials and their replacement
You choose roofing for 40 years. The pitch, roof truss load capacity, local weather conditions and the desired appearance of the house are decisive factors. Below is a comparison without prices; costs vary by brand and scope and will be provided in the quotation following an inspection.
Comparison of roofing materials
| Roofing materials | Minimum slope | Weight | Service life | Suitable for |
|---|---|---|---|---|
| Clay tile | from approx. 22° | high | 60 years and more | traditional houses, heritage zones, long service life |
| Concrete roof tile | from approx. 22° | high | 40 and more years | standard detached houses, good price-to-durability ratio |
| Beaver-tail tiles | from approx. 30° | high | 60 years and more | historic houses, curved shapes, dormer windows |
| Metal tile | from approx. 12° | low | 30 to 50 years | older roof trusses, quick replacement |
| Standing seam metal | from approx. 3° | low | 50 and more years | low-pitched and shed roofs, modern houses |
| Asphalt shingles | from approx. 15° | low | 25 to 35 years | cabin roofs, complex shapes, small roofs |
| Fibre-cement | from approx. 25° | medium | 30 to 40 years | asbestos-free replacement for Eternit |
The values are indicative based on standard installation instructions. Below the minimum slope, additional waterproofing measures are required.
Selection criteria
- Slope. Below 20 degrees, tiles are removed, leaving only metal sheeting and shingles. Try it out. slope gauge.
- Roof truss. Heavy tiles require a sound and properly sized roof structure, whereas sheet metal can be supported by almost any frame.
- Location. Mountains and wind favour sheet metal; heritage zones favour tiles.
- Appearance. The colour and texture of the roofing material determine whether notification is required (change to the appearance of the building).
How the roofing replacement process works
Removal of old roofing material, inspection of battens and roof structure, new underlayment and counter-battens, battens according to the spacing required by the roofing material, laying, ridge tiles and corner pieces, sheet metal work, cleaning. A sound roof structure is not replaced, so this replacement is faster and cheaper than a full reconstruction. If the old roofing material is eternit, we will arrange authorised removal and disposal of asbestos.

Questions we are asked
Can I use tiles instead of sheet metal?
Only if the roof structure can support it. Tiles are five times heavier than sheet metal, so we first assess the rafters, spacing and condition. Sometimes adding purlins is enough; other times it is safer to stick with lightweight roofing.
Is a fired clay tile better than a concrete one?
Clay tiles have a longer lifespan, more stable colour and better frost resistance; concrete tiles are cheaper and dimensionally more precise. Both are a good choice; the difference lies in price and appearance.
Do I need a permit to replace the roofing material?
Replacement with the same type and colour is usually not required. A change in appearance or a property in a heritage zone typically requires notification. We will verify this before starting work.
