A practical look at 404 pages for a roofing crew
18 Mar 2025
How a roofing crew deals with 404 pages — and what usually goes wrong.
The problem: a CAA record that blocks the new CA. This breaks 404 pages for a roofing crew.
We once forgot to renew 404 pages for a weekend project and it took down a page that a roofing crew linked to from a print flyer. We now set auto-renew on everything.
Instead of migrating 404 pages all at once, we ran both configurations in parallel for a week. The switch happened on a Wednesday morning — the quietest traffic window.
When a roofing crew moved hosts, the outage was not the new box — it was a CAA record that blocks the new CA. We keep TTL short the week of a move, then raise it once everything is stable.
If the hours on Google disagree with the site, people trust Google and then arrive angry. 404 pages will not fix that. The hours page will.
The owner at a roofing crew asked why 404 pages matters. We showed them the error page their customers see when it breaks. That ended the conversation.
Most of the damage we see in 404 pages comes from doing too much. A single correct record beats three that were supposed to be clever.
Six months later, a roofing crew asked us to look at something unrelated. While we were in the panel, we noticed a CAA record that blocks the new CA had crept back. We fixed it before it caused trouble.
