What does a roofing consultant do?

A roofing consultant evaluates roofing conditions, investigates leaks, reviews roofing designs, and provides technical guidance on repair and replacement projects. An independent roofing consultant helps building owners make informed decisions about roofing performance, maintenance, and long-term asset management.

What causes recurring roof leaks in commercial buildings?

Recurring roof leaks may result from deteriorated membranes, failed flashing, poorly detailed penetrations, inadequate drainage, or deficiencies at roof-to-wall transitions. Water can also travel within roof assemblies before becoming visible inside a building. A professional investigation helps identify potential water entry paths and develop appropriate repair recommendations.
