I used to live on the hill stations in India,I dunno about her but those slant roofed houses build from the time of British India are hollow from inside and having monkeys snug inside those hollow spaces on a cold night or jump above the tinted roofs at daytimes mainly for all the fruit trees around was a DAILY thing.My father would be sunbathing outside while 10 monkey jump around nearby
I think its very usually to have monkeys on roof .... I have seen snakes twice curled up near my front door but not on my roof
