Commercial roof restoration renews an aging roof without tearing it off. The crew repairs damaged areas, replaces wet sections and applies a new surface, usually a coating system, over the existing membrane.
Restoration versus replacement
| Restoration | Replacement | |
|---|---|---|
| Existing roof | Stays in place | Removed or covered |
| Disposal | Minimal | Often significant |
| Disruption | Usually lower | Higher |
| Candidate roofs | Aged but sound, mostly dry | Any, including failed roofs |
Is your roof a candidate
A roof is a good candidate when:
- Most of the insulation is dry, confirmed by a moisture survey or core samples
- The deck is sound
- The membrane is weathered but not failing across the field
- Leaks are isolated and repairable
A roof with widespread wet insulation or deck damage usually needs replacement instead.
The restoration process
- Survey and moisture scan
- Remove and replace wet areas
- Repair seams, flashings and penetrations
- Clean and prime the surface
- Apply the coating system at the specified thickness
- Final inspection and warranty registration
Restoration works best when it is followed by regular maintenance.
Common questions
Is restoration cheaper than replacement?
Usually, because the existing roof stays in place and there is little tear off or disposal. The roof must be a good candidate for the savings to be real.
Can a restored roof carry a warranty?
Many coating manufacturers offer warranties on restoration systems installed by approved contractors, subject to their inspection.
