Owner's book · not a shop
Know the car. Then the window. Factory specs in plain English — don't authorize until you can say this at the counter.
Playbooks
Beginner · short stepsExpert · spec · code · mm
Pick the situation. Read the left column. Say that at the window.
Twelve owner scenarios. Beginner script + genius measurements. SaferCar patterns — not a pirated TSB book.
Playbooks · Who · Which roof
Who to call for what. We book nobody.
Dealers own the campaign and the factory scan. Independents often own the diagnosis hour. Chains own convenience and a menu. Match the job to the roof. Open Hood does not certify anyone and does not take a booking fee.
You need work and three signs are yelling. You want a rule of thumb, not a sponsored list. Then you still ask for millimeters.

Expert notes
Factory scan vs $20 reader · OEM vs generic
A cheap tool reads generic P-codes. Module-level codes, calibrations, and campaign software live on dealer (or equivalent OEM) tools. That is why a “no codes” indie scan can still miss an SRS campaign.
Posted rate vs book time · $ / hour
Ask the door rate and whether the line is clock time or a book hours. We do not invent TecDoc times. If they cannot tell you which one they used, you cannot audit the line.
Shop supplies · % or $
A capped percent or a printed flat is normal. An untitled 12% on top of a $2,000 job is a conversation. Ask it before they start, not at pickup.
