1According to ÖNORM B 3419, what is the definition of the standard roof pitch (Regeldachneigung) for pitched roof coverings?

A.The lowest pitch limit at which a specific roof covering material has proven in practice to be sufficiently rainproof without requiring additional specialized under-roof waterproofing measures.

B.The maximum permissible structural pitch beyond which roof tiles must be 100% mechanically screwed rather than clipped.

C.The theoretical pitch angle at which snow cannot accumulate under any circumstances due to gravitational slip.

D.The minimum pitch required strictly to ensure rainwater runoff into eaves gutters without exceeding downpipe hydraulic capacity.

Explanation: In Austrian roofing standards (ÖNORM B 3419), the standard roof pitch (Regeldachneigung) is defined as the lower pitch limit at which a specific roofing material (such as plain tiles or interlocking tiles) provides proven, long-term rain resistance under standard climatic conditions without requiring heightened sub-roof waterproofing measures (erhöhte Zusatzmaßnahmen / Unterdach). When the actual roof pitch is lower than the Regeldachneigung, ÖNORM B 4119 mandates specific supplementary under-roof measures (such as an erhöht regensicheres or wasserdichtes Unterdach).

2A master roofer is planning a plain tile double lap covering (Biberschwanz-Doppeldeckung) per ÖNORM B 3419. The plain tiles have a standard length of 380 mm, and the required headlap (Höhenüberdeckung ü) is specified as 80 mm. What is the exact batten spacing (Lattweite / Lattenabstand l_a)?

A.150 mm (15.0 cm)

B.300 mm (30.0 cm)

C.190 mm (19.0 cm)

D.110 mm (11.0 cm)

Explanation: In a Biberschwanz double lap covering (Doppeldeckung), each course of tiles rests on its own batten and overlaps two courses beneath it. The standard mathematical formula for batten spacing is l_a = (l - ü) / 2. Substituting tile length l = 380 mm and required overlap ü = 80 mm: l_a = (380 mm - 80 mm) / 2 = 300 mm / 2 = 150 mm (15.0 cm).

3For a plain tile crown lap covering (Biberschwanz-Kronendeckung per ÖNORM B 3419) using 380 mm tiles with a required overlap (Höhenüberdeckung ü) of 80 mm, what is the required batten spacing (Lattweite l_a)?

A.300 mm (30.0 cm)

B.150 mm (15.0 cm)

C.260 mm (26.0 cm)

D.340 mm (34.0 cm)

Explanation: In crown lap roofing (Kronendeckung, also known as Ritterdeckung), two tile layers (bearing course and covering course) are hung on the same batten. The batten spacing is calculated using the formula l_a = l - ü. With l = 380 mm and ü = 80 mm, l_a = 380 mm - 80 mm = 300 mm (30.0 cm).

4Under Austrian standards ÖNORM B 3419 and ÖNORM B 4119, what is the essential structural distinction between a 'watertight under-roof' (wasserdichtes Unterdach) and an 'increased rainproof under-roof' (erhöht regensicheres Unterdach / UD Typ 2)?

A.In a watertight under-roof, the counter-battens are integrated directly into the waterproofing membrane layer or fully covered with welded membrane strips, whereas in an increased rainproof under-roof, counter-battens are mounted on top of the membrane using nail-sealing tapes (Nageldichtbänder).

B.A watertight under-roof allows counter-battens to be fixed with unsealed wire nails, whereas an increased rainproof under-roof mandates hot-air welded counter-batten shoes.

C.An increased rainproof under-roof requires full bitumen hot-melt asphalt, whereas a watertight under-roof only uses loose-laid microperforated diffusion foils.

D.A watertight under-roof can only be installed on roofs with pitches above 45°, whereas an increased rainproof under-roof is restricted to flat roofs with slopes under 2°.

Explanation: ÖNORM B 4119 distinguishes under-roof classifications: in a watertight under-roof (wasserdichtes Unterdach), the waterproofing membrane completely envelopes the counter-battens (eingebundene Konterlattung) or counter-battens are placed below/sealed seamlessly into the membrane, eliminating penetration points from fasteners. In an increased rainproof under-roof (erhöht regensicheres Unterdach, UD Typ 2), the counter-battens are positioned above the membrane on full timber sarking, and fastener penetrations are sealed using certified nail-sealing tapes (Nageldichtband) with bonded seams/overlaps.

5What are the standard minimum ventilation cross-sections (Hinterlüftungsquerschnitte) required at the eaves (Traufe) and ridge (First) for a ventilated pitched tile roof per ÖNORM B 3419 / DIN 4108-3?

A.At least 200 cm² per meter of eaves width (and at least 0.2% of the associated roof surface area), and at least 50 cm² per meter of ridge length (or 0.05% of the associated roof area).

B.At least 500 cm² per meter of eaves width, and at least 500 cm² per meter of ridge length regardless of rafter length.

C.At least 50 cm² per meter of eaves width, and at least 200 cm² per meter of ridge length.

D.A uniform 100 cm² per meter of eaves width, with no ventilation opening required at the ridge if an underlay is installed.

Explanation: ÖNORM B 3419 (and complementary building physics rules in DIN 4108-3) mandates a minimum clear ventilation opening at the eaves of 200 cm²/m (or 0.2% of the tributary roof area, with a minimum counter-batten cavity height of 24–30 mm depending on rafter length). At the ridge/hip, the exhaust ventilation opening must provide at least 50 cm²/m (or 0.05% of the tributary roof slope area).

6A pitched roof has a long rafter length of 12.0 m and a roof pitch of 25°. To maintain the required 0.2% ventilation volume and compensate for airflow resistance and bird mesh blockage at the eaves per ÖNORM B 3419, what is the recommended minimum counter-batten height (Konterlattenhöhe)?

A.50 mm (e.g., 50 x 50 mm or 50 x 80 mm counter-battens)

B.24 mm (standard lath thickness)

C.10 mm (thin battens)

D.100 mm structural timber

Explanation: While 24–30 mm counter-battens are permissible for short rafter lengths (under 6–8 m) and standard pitches, for long rafter runs (> 10 m) or lower pitches, ÖNORM B 3419 requires increasing the counter-batten cavity height to at least 50 mm. This ensures that the effective ventilation cross-section of at least 200 cm²/m is preserved after accounting for eave ventilation grilles (Lüftungsgitter) which reduce free airflow area by 30–50%.

7What is the standard roof pitch (Regeldachneigung) for concrete roof tiles with lateral interlocking (Betondachsteine per ÖNORM B 3419) under standard climatic conditions in Austria?

A.22°

B.15°

C.30°

D.35°

Explanation: Per ÖNORM B 3419, the standard roof pitch (Regeldachneigung) for concrete roof tiles with side interlocking (e.g., standard profiles like Frankfurter Pfanne / Classic) is 22°. If installed between 17° and 22°, an increased rainproof underlay/under-roof (regensicheres/erhöht regensicheres Unterdach) is required, and below 17° down to 12°, a watertight under-roof (wasserdichtes Unterdach) is required.

8In traditional natural slate roofing according to Austrian craft conventions (Altdeutsche Schieferdeckung), what are the two defining geometric rules regarding course height reduction (Verjüngung) and lap direction (Hiebrichtung)?

A.The slate course heights decrease progressively from eaves to ridge (Verjüngung des Gebindes), and the visible outer slate edges face away from the prevailing wind direction (Hiebrichtung mit dem Wind).

B.The slate course heights increase from eaves to ridge to catch more snow, and the outer edges face directly into the prevailing storm wind.

C.All slate courses must maintain a constant height of exactly 25 cm, and the lap direction must alternate every second course.

D.Course heights decrease towards the eaves, and slates must always be laid with vertical straight butt joints.

Explanation: In Altdeutsche Deckung, the largest slates are placed at the eaves where water volume is highest, and course heights gradually decrease towards the ridge (Verjüngung / Steigender Bund). Furthermore, slates are laid with the overlap directed away from the prevailing weather direction (Hiebrichtung mit dem Wind / rechter oder linker Hieb) so driving rain and wind glide smoothly over the joints without penetrating.

9In natural slate rectangular double lap roofing (Rechteck-Doppeldeckung), how is the visible exposure / batten gauge (Lattweite l_a) calculated for a slate of length l with a required headlap ü?

A.l_a = (l - ü) / 2

B.l_a = l - ü

C.l_a = (l - 2 * ü) / 3

D.l_a = l / 2 + ü

Explanation: Rectangular double lap slate roofing (Rechteck-Doppeldeckung) follows the identical geometric principle as Biberschwanz double lap covering: each course is covered by two layers above it. Therefore, the gauge/batten spacing is l_a = (l - ü) / 2.

10A roof is covered in rectangular natural slate double lap (Rechteck-Doppeldeckung) using slates measuring 300 mm length by 200 mm width with an overlap (ü) of 80 mm. The slate thickness is 5.0 mm and the slate density is 2,700 kg/m³. What is the approximate number of slates per m² and the resulting dead load of the slate covering per m² (excluding battens)?

A.Approx. 45.5 slates/m² and approx. 36.8 kg/m² (0.37 kN/m²)

B.Approx. 22.7 slates/m² and approx. 18.4 kg/m² (0.18 kN/m²)

C.Approx. 60.0 slates/m² and approx. 52.5 kg/m² (0.53 kN/m²)

D.Approx. 33.3 slates/m² and approx. 27.0 kg/m² (0.27 kN/m²)

Explanation: 1. Batten gauge l_a = (l - ü) / 2 = (0.30 m - 0.08 m) / 2 = 0.11 m (110 mm). 2. Exposed area per slate = l_a * width = 0.11 m * 0.20 m = 0.022 m². 3. Slates per m² = 1 / 0.022 m² ≈ 45.45 slates/m². 4. Volume per slate = 0.30 m * 0.20 m * 0.005 m = 0.0003 m³. 5. Mass per slate = 0.0003 m³ * 2,700 kg/m³ = 0.81 kg. 6. Total dead load = 45.45 * 0.81 kg ≈ 36.8 kg/m² (~0.37 kN/m²).

Meisterprüfung Dachdecker Study Tips from Top Performers

1Master batten spacing calculations for Biberschwanz tiles: for double lap (Doppeldeckung), gauge l_a = (length - overlap) / 2; for crown lap (Kronendeckung), gauge l_a = length - overlap.

2Know under-roof classifications under ÖNORM B 4119: understand when a watertight under-roof (counter-battens wrapped/embedded in membrane) is mandatory versus an increased rainproof under-roof UD Typ 2 (counter-battens on top with Nageldichtband) based on pitch undershoot below the Regeldachneigung.

3Memorize flat roof slope and upstand requirements per ÖNORM B 3691: standard slope G1 >= 2.0% (min 1.5% at drainage points); minimum upstand height >= 15 cm above the finished surface (reduced to 10 cm on slopes > 5° or 5 cm at door thresholds when using drainage channels).

4Calculate snow load on roofs per ÖNORM EN 1991-1-3: s = mu_1 * C_e * C_t * s_k, where mu_1 = 0.8 for pitch <= 30°, mu_1 = 0.8 * (60 - alpha) / 30 for 30° < pitch < 60°, and 0 for pitch >= 60°; and determine snow guard line load F_s = s * L * sin(alpha).

5Understand wind suction mechanics per ÖNORM EN 1991-1-4: calculate peak velocity pressure q_p, corner/eave suction zones F and G (high c_pe coefficients), and verify whether tile self-weight g_k * cos(alpha) suffices or storm clips (Sturmklammern) are required.

6Review roof drainage formulas per ÖNORM EN 12056-3: calculate design flow rate Q = r * A * C and ensure every flat roof has an independent emergency overflow (Notentwässerung) sized for catastrophic storm events discharging to open terrain.

7Familiarize yourself with worker safety and fall arrest standards: know BauV triggers (mandatory fall protection for roof work at heights >= 3.00 m) and ÖNORM B 3417 equipment classes (Class 1 single anchors, Class 2 horizontal lifelines, Class 3 collective guardrails, Class 4 public access).

8Understand ÖNORM B 2219 contract and measurement rules: openings under 2.5 m² (chimneys, skylights) are measured over without deduction (Übermessungsregel), and understand the 3-year statutory warranty under ABGB § 933.
