How a roofing crew should handle DNS TTL
24 Jul 2025
How a roofing crew deals with DNS TTL — and what usually goes wrong.
The problem: a backup that was never restored as a drill. This is where DNS TTL breaks for a roofing crew.
For a roofing crew, we wrote a three-line script that checks DNS TTL every morning and emails the owner if anything changes. Total cost: zero.
We got a call from a roofing crew on a Friday. Their DNS TTL had expired overnight, and the booking page was returning errors to every visitor.
WordPress can handle DNS TTL with a plugin. But the plugin adds JavaScript, a dashboard, and a support ticket when it conflicts with the next update. We wrote four lines of config instead.
Maintenance is not glamorous, but it is the reason a roofing crew has not had downtime since we took over DNS TTL. The invoice is small and the peace of mind is large.
We hand over a one-page document after every DNS TTL job. It says what was changed, what the login is, and what to check if something feels wrong. a roofing crew keeps it in a drawer they actually open.
