Insurance on commercial building

[William Tong]

I have insurance on a NNN single tenant building. The tenant, Workout Anytime, has insurance for his equipment and business related structures. I have had 4 roof leaks in the past year and have decided to replace the whole roof. In the experience of the readers, should the tenant's insurance cover any leak related internal damage? Should my insurance on the building cover roof leaks? Of course I am contacting the insurance companies but thought someone here may have recommendations. Thanks for anyone's help.
