Plan roof work around a working building. Start with the system, moisture condition and drainage, then compare repair, restoration and replacement.
A ceiling leak in a business can interrupt stock, tenants and daily work. The roof decision needs to account for the membrane above it and the insulation and support beneath it. An isolated open seam and a broad area of wet insulation need different work.
A commercial roof walk looks at seams, perimeter edges, drains and the flashings at equipment curbs and penetrations. The roof type, attachment and moisture condition help establish which options remain useful. Tell us the building use and whether an active leak is affecting an occupied space.

A compatible repair can address a seam, puncture or flashing defect when the surrounding system is sound. The water path and the affected layers need to be established.
A coating or restoration system needs a compatible, prepared, sufficiently dry and well-attached base. It cannot restore wet insulation or replace failed support.
Widespread moisture, deterioration or attachment problems can make removal and a new assembly the useful route. Replacement can address drainage and insulation as part of the design.

Explore the service| Building concern | What the work plan needs to address |
|---|---|
| Occupants and operations | Entrances, tenant communication, material movement and protection of sensitive interior uses. |
| Roof access and staging | Safe access, loading locations, debris handling and space needed for the selected work. |
| Rooftop equipment | Equipment curbs and penetrations need coordinated flashing. HVAC, electrical or other trade work stays clearly identified. |
| Drainage | Drains, scuppers and slope direct water off the roof. Persistent ponding needs its cause assessed rather than a coating assumed to solve it. |
Yes, when the defect is localized and the surrounding roof and underlying layers support a compatible repair. Moisture and attachment conditions can change that decision.
No. Wet insulation needs to be identified and addressed. A coating is a surface restoration system, not a repair for damaged layers below the membrane.
Occupancy belongs in the project discussion. Building use, access, equipment and the selected installation method determine how the work can be organized.
