For shallow pitches or flat roofs on all or certain areas of your office, consider a Green roof. The technology has become very sophisticated and the insulation benefits are terrific, as is the run-off water prevention. Plant-filled rooftops offer an attractive and energy-saving alternative to a conventional one. You can either run the planting with the soil directly integrated into the roof and drainage system or add planting 'trays'. In either case, you will increase the structural load on your roof, so check with an engineer accordingly.

The advantage of the planting tray option is that you can test it out in stages and add more as your budget permits. One of the advantages of a green roof that is a great feature for employees is the ability to let them enjoy the space for lunch breaks or even outdoor meetings when the weather permits. Green roofs typically cost $8 to $10 a square foot, whereas a regular roof costs about $4 to $6 a square foot. In addition to energy savings via the insulation factor, one of the top reasons for installing a green 'living' or vegetated roof is to absorb rainwater.

The ROI Calculation is based on the offset cost of a 2,000 sq. ft. section of a small office building. This calculation factors in the replacement cost of typical roof once over 20 years, and spreads the savings across the ten year life of the calculation.
