A few guidelines can reduce your cost and save you money down the line:
The PRI Preventive Roof Maintenance (PRM) is intended to provide owners of facilities an alternative to manufacturer’s roofing system warranties, which generally provide no protection against conditions, which usually result in leakage to the interior, and no provision for preventive maintenance of roofing assemblies. Roof system warranties issued by manufacturers become potentially effective only when the roof actively leaks; there is no provision for anticipation of leakage nor is there provision for corrective action to all roof assembly components affected by leakage.
Once or twice a year (or more often if conditions dictate), an experienced roof auditor will walk the roof areas covered by the PRM, conduct a visual audit and an informal non-destructive survey of the roof(s) and provide a written report and pictures on existing roof conditions. All routine maintenance required will be noted for corrective action. If the roofing assembly has been damaged by wind, lightning, other maintenance contractors, or facility maintenance personnel, a written proposal for the cost to repair such damage will be provided with the report.
Following each audit, a PRI maintenance crew will be dispatched to the facility to perform routine maintenance to the roofing assemblies (top-off pitch pans, clean drain strainers, repair minor damage to membrane flashings, re-secure existing loose accessory metal, etc.). If the PRI. repair proposal (if applicable) has been accepted by a facility representative, the maintenance crew will complete repairs to the damaged roof areas during the time of maintenance work.
