With any commercial roof restoration, the eligibility is determined on the condition of the existing roof system. If your existing metal roof is severely damaged, then restoration may not help your problems or even be possible.
The best way to find out if your facility is eligible for a spray on roof coating, you should schedule a contractor to evaluate your existing roof system. They will be able to recommend the best solution for your facility needs.
For an existing roof system to be eligible for a roof restoration, the roof needs to be in better condition than most roofs at the end of their serviceable life. Some signs of a roof in good condition include:
- The seams of the existing membrane are relatively intact
- The field of the roof has been adequately maintained over its life
- Less than 25% of the underlined substrate and insulation is wet (It is still cost-effective to do spot replacement of small saturated areas rather than a complete replacement.)
