A Roofing Plan You Can Understand Before Work Starts
A roof leak does not always begin directly above the stain you see inside. Water can travel from flashing, seams, penetrations, roof edges or drainage areas before it becomes visible indoors. That is why Rohan’s starts by assessing the roof and explaining the likely source instead of treating every leak as the same problem.
The current Rohan’s process includes inspection, photos, a written scope and pricing in plain language. For roof projects, the company states a ten-year workmanship warranty, with manufacturer material coverage handled separately. Any change to the agreed scope is presented for approval before the additional work proceeds.

Details Around Seams, Flashing and Drainage Matter
Flat roofs depend on more than the field membrane. Roof edges, penetrations, flashing and drainage conditions all affect how water moves across the roof. When a leak appears, identifying the entry point and the surrounding conditions helps determine whether a localized repair is appropriate or whether a larger section needs attention.
Rohan’s states that it repairs ponding, failed flashing and membrane damage. For winter or poor-weather conditions, work is scheduled within product and safety requirements because some materials need dry or warmer conditions.
