I understand your statement however we just don’t have time to stop workflow and work all supplements ahead of time. Also some supplements require to be done after roof removal (existing items).
We get short changed constantly.
It doesn’t matter what we say it will take for material. These companies are set on their numbers so we have a supplement on 95% of jobs and it’s just became one of those ordeals where we just make sure and ask on every single one for what is rightfully owed. Maybe one day all that work will pay off and all of that proof of asking even though we won’t receive will be our evidence.
