I searched and followed whatever stackoverflow answers suggested to get that latest website cache on Facebook.
After following multiple answers, this is my fat head

What I tried To Clear Cache:
1) https://developers.facebook.com/tools/debug/og/object/ with url: https://www.livelyroof.com
2) https://developers.facebook.com/tools/debug/sharing/?q=https%3A%2F%2Fwww.livelyroof.com
1) and 2) Result: The 'og:image' property should be explicitly provided, even if a value can be inferred from other tags. The following required properties are missing: og:url, og:type, og:title, og:image, og:description, fb:app_id
3)https://developers.facebook.com/tools/debug/og/object/ with https://www.livelyroof.com?fbrefresh=CAN_BE_ANYTHING
3) and 4) Result: Object at URL 'https://www.livelyroof.com/?fbrefresh=CAN_BE_ANYTHING' of type 'website' is invalid because the given value 'assets/img/1.png' for property 'og:image:url' could not be parsed as type 'url'.
Now, when I try to share url on FB, random image from website is shown as website preview instead of omg:image:url
