Eventually, every commercial roofing system must be replaced. But, with inspection, maintenance and repair, building owners can extend a roofing systems life cycle to maximize their return on investment.
According to the National Roofing Contractors Association preventive maintenance adds 30%-100% service life to a commercial roofing system. That means repair costs could be triple the cost of a preventive maintenance program over the life cycle of a commercial roofing system.
Another facilities management factor to consider in maintaining roofing systems is energy management. Wet insulation in a roofing system loses energy. According to the Building Owners and Managers Institute, good maintenance practices and good energy management go hand in hand. Some of the highest rates of return on energy conservation are generated simply by performing maintenance.
The key element to an effective facility asset management process is having professionals inspect those assets on a regular basis. On a periodic schedule determined with the building owner or manager the following should be done;
* Inspect the entire roofing system including flashings, drains or gutters and leaders, masonry, etc.
* Document each inspection (roof plan, inspection forms, and photo documentation). Each technician should carry a digital camera to document noteworthy roof conditions. Digital photos can be included with inspection reports.
* Perform infrared testing as needed to provide thermal energy reports to identify moisture within a roof system
* Remove all debris, clean gutters, leaders and drains
* Make minor repairs at the time of inspection.
* Provide estimates for roof repairs (or replacement if necessary)
* Comply with and document compliance with the maintenance requirements of any roofing system manufacturer warranties in effect.
Physical rooftop inspections and color infrared camera surveys are the keys to the effective documentation and analysis of energy loss, roof repair and maintenance issues.
In addition to the information gathered during roof inspections, the importance of maintaining warranty, design, installer, as-built materials data, and repair history information should be emphasized. Contractors will benefit from assisting in the compilation of this additional data.
If this process is followed, the repair, maintenance and energy conservation of commercial roofing systems will be as cost-effective as possible, and with this process, facilities-manager clients know years in advance of when a roofing system will have to be replaced, and what its projected expense will be.
