Would a new roof lantern installed in a existing flat roof require rsjs?

I'm thinking of getting a roof lantern installed into a pitched roof area would this require any rsjs?

How many sqaure meters is your flat roof and what is the weight of your lantern

Size relative is the simple answer.
We are installing one at the moment which is 7m x 4m and our structural engineers have called up for 2 rsjs 203 x 133 x 30 to carry the load of the new flat roof and skypod and any additional imposed loadings such as snow. Recommend getting engineers report in most instances.
