I put a roll-up door in my shed. The door height is 8ft..so the door roll is less than 18"
The door size will specify the clearance needed.
I really like the convenience of a roll-up. One finger to lift it..and it seals up good.

Maybe get some specs from a page like this...https://www.ebay.com/itm/Insulated-Roll-Up-Door-106-wide-x-100-high-with-lift-handle/141774880240?_trkparms=aid%3D222007%26algo%3DSIM.M BE%26ao%3D1%26asc%3D20160908110712%26meid%3D86c294 e598264e9f89ff933eddae4747%26pid%3D100677%26rk%3D2 %26rkt%3D25%26sd%3D141236416038&_trksid=p2385738.c100677.m4598
