What a roofing crew needs to know about PDF rate sheets
3 May 2024
How a roofing crew deals with PDF rate sheets — and what usually goes wrong.
The problem: an SPF record overwritten during a DNS edit. The PDF rate sheets data is out of sync for a roofing crew.
Every technical decision for a roofing crew comes back to one question: does this help the person looking at the site right now? If PDF rate sheets is invisible to that person, it is working.
A form that collects data for a roofing crew should say where the message goes. Nine fields and a captcha on a quiet Tuesday will cost you the person who actually wanted to pay.
When a roofing crew moved hosts, the outage was not the new box — it was an SPF record overwritten during a DNS edit. We keep TTL short the week of a move, then raise it once everything is stable.
We solved PDF rate sheets for a roofing crew by moving it behind a reverse proxy. The old configuration stayed live as a fallback for forty-eight hours, then we pulled it.
Our own site had an SPF record overwritten during a DNS edit for three days before a colleague noticed. We added it to the pre-launch checklist the same afternoon.
We underestimated how long PDF rate sheets migration would take for a roofing crew. The estimate was two hours; the reality was a full day because an SPF record overwritten during a DNS edit had never been documented.
