The software you picked is probably fine. Most of them are. What kills a rollout is the four weeks after the decision, when the tool has to survive a crew that is already busy and did not ask for it.
I have watched good products die because they were introduced on the wrong day, and mediocre ones stick because somebody sequenced the first month properly.
Week one: one person, real jobs
Do not roll out to the crew. Roll out to one inspector.
Pick the one whose opinion the others actually listen to, which is not necessarily the most senior or the most enthusiastic. Enthusiasts are bad first users because their endorsement is discounted by everyone else. You want the credible skeptic.
Give them a week on real inspections, not a sandbox. The whole point of running the trial on live jobs is that the failure modes only appear on real roofs — gloves, glare, a homeowner who is late, two bars of signal.
Your job that week is to collect the friction, not to defend the tool. Every "this is annoying" is worth more than a compliment, because it is what the rest of the crew will hit in week three.
Week two: fix the friction before you widen
This is the step everyone skips, and skipping it is why rollouts stall.
Whatever your first user hit — a login that keeps timing out, a step in the wrong order, a setting nobody knew about — sort it before anyone else sees it. Half of it is configuration, half is knowing a thing exists. Almost none of it requires the vendor.
Then write the shortest possible instruction. Not a manual: the five steps of a normal job, on one page, in your company's own words, with your own screenshots. Every product ships documentation for its whole surface area. Your crew needs the ninety percent path and nothing else.
Week three: the rest of the crew, with a floor not a ceiling
Now widen, and set the expectation as a minimum rather than a total conversion.
"Every inspector runs this on at least one job this week" is achievable, and it gets everyone past the first-time awkwardness that is most of the resistance. "We are switching to this for everything" invites a debate you do not need to have yet, and one bad first experience becomes an argument for going back.
Expect a dip. Week three is slower than the old way, because everything new is. Say that out loud in advance, because an unpredicted dip reads to a crew as proof the tool is bad, and a predicted one reads as the cost of learning.
This is also where onboarding a new inspector and rolling out software converge: the same one-page path serves both, and if it does not work for a new hire it will not hold for a veteran either.
Week four: make it the default, and let the record prove it
Adoption sticks when the new thing is how the work is counted, not an extra thing on top of the work.
The clearest move: if the job is not in the system, it is not documented. Not a threat — just the same rule you already have about paperwork, pointed at the new place. As long as there is a parallel path, the parallel path wins, because it is familiar.
Then show them their own evidence at the end of the month. Not vendor marketing — your jobs. The walk where the homeowner said yes on the roof. The callback that got answered from a recording in two minutes. A crew that has seen its own wins argues for a tool better than any rollout plan does.
What sinks it
Three things, and they are all schedule, not software.
Launching in your busiest week. Making it optional indefinitely. And the owner not using it — nothing signals "this is not real" faster than a rollout the person who bought it does not personally touch.
The most reliable predictor of a rollout working is whether the first month was planned as carefully as the purchase was. If you are still evaluating, the free week is week one of this plan; the use cases page covers what crews of different sizes actually do with it.
InspectStream records what an inspector observed. It is not a public adjusting service and does not prepare, negotiate, or advise on insurance claims.
