Loads Due to Rain:

This load to be considered separately if due to certain reasons accumulation of rain water becomes possible on roofs; otherwise provisions of Table 6 are sufficient.

Every member which is directly supporting the roof covering shall be designed to carry the more severe of the loads caused by live load and wind load (given in the next section) or an incidental concentrated load of 0.9 kN placed at the most unfavourable position of the member. A roof covering also should be capable of carrying this load concentrated on an area of 12.5 cm square. (This load might be reduced up to 0.5 kN along with the approval of the Engg-in-charge where it is ensured that the roof covering would not be traversed without suitable aids).
