Porogaramu yashizweho kugirango ibare igisenge cya atike: ingano y'ibikoresho byo gusakara n'ibisenge, battens na rafters.
Urashobora kandi kubara ingano yingirakamaro yinzu.

Ibiharuro byerekana ubunini cyangwa ubunini bwibikoresho byigice cyigisenge no mumurongo ubunini cyangwa ubunini bwinzu yose.

Icyitonderwa! Iyo ubara impapuro (ondulin, icyapa cyangwa icyuma) Reba icyo gahunda itekereza kubisenge.
Kurugero, imirongo 2.8 igwiza impapuro 7.7 kumurongo. Mu bwubatsi nyabwo, hashyizweho imirongo 3.
Kugirango ubare neza neza umubare wamabati, birakenewe kugabanya uburebure bwurupapuro mumibare kugirango ubone umubare wuzuye wumurongo.
Ntiwibagirwe gushiraho agaciro karenze neza (kubikoresho bitandukanye birashobora kuba bitandukanye - kurikiza ibyifuzo byababikora).

Nongeye kubibutsa ko mukeneye kugura ibikoresho byubwubatsi hamwe n’imyanda.
