A repair is easier to evaluate when the affected area has a documented baseline. Monitoring should record the same interior locations after relevant weather, while keeping the contractor's completion photographs and scope together.
What to do next
Agree on how to report recurrence and what follow-up the repair arrangement includes. Do not use the absence of one rainy-day stain as a lifetime assurance. Keep records of changing conditions so a later visit can distinguish old marks from new moisture.
