Question 1

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

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. The maximum permissible structural pitch beyond which roof tiles must be 100% mechanically screwed rather than clipped. The theoretical pitch angle at which snow cannot accumulate under any circumstances due to gravitational slip. The minimum pitch required strictly to ensure rainwater runoff into eaves gutters without exceeding downpipe hydraulic capacity.

Correct Answer:

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.

Question 2

A 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)?

150 mm (15.0 cm) 300 mm (30.0 cm) 190 mm (19.0 cm) 110 mm (11.0 cm)

Correct Answer:

150 mm (15.0 cm)

Question 3

For 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)?

300 mm (30.0 cm) 150 mm (15.0 cm) 260 mm (26.0 cm) 340 mm (34.0 cm)

Correct Answer:

300 mm (30.0 cm)

Question 4

Under 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)?

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

Correct Answer:

Question 5

What 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?

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). At least 500 cm² per meter of eaves width, and at least 500 cm² per meter of ridge length regardless of rafter length. At least 50 cm² per meter of eaves width, and at least 200 cm² per meter of ridge length. A uniform 100 cm² per meter of eaves width, with no ventilation opening required at the ridge if an underlay is installed.

Correct Answer:

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).
