Simplified imposed roof loads by altitude and zone
Table 4B.2 specifies imposed roof loads in kN/m² based on site altitude above sea level and geographic zone (A or B), ranging from 0.75 to 1.00 kN/m².
Table 4B.2 Simplified imposed roof loads
Altitude of site above sea level (m) | Zone A (kN/m2) | Zone B (kN/m2)
from 0 to 100 | 0.75 | 0.75
more than 100 but not more than 150 | 0.75 | 0.75
more than 150 but not more than 200 | 0.75 | 1.00
more than 200 but not more than 250 | 1.00 | 1.00
