However, it only says the following with regards to umbrella roofs:
Edition: 9th - Feb. 1996
Section: 1.2.1
Inquiry No.: 620-I-10/00
Question 1: Does Section 1.2.1 prevent tanks with umbrella roofs and eccentric cones, from being marked as being in accordance with API Standard 620?
Reply 1: No.
Edition: 10th - Feb. 2002
Section: 5.1.1
Inquiry No.: 620-I-05/02
Question: Are umbrella roofs, eccentric cone roofs and bottoms, and bottoms sloped to one side, among those designs for which API 620 does not present design rules as noted in Section 5.1.1?
Reply: Yes.
Are there other technical interpretations available?

There was an older one that basically said you couldn't use umbrella roofs on an API-620 tank, and I think the item above is an update to it.
