Photovoltaic Installations

With the foundation of our business solidified in roofing and waterproofing, we understand the very basics to the very complex components of a roofing assembly system.  As the realm of renewable energy began to emerge (ROOFTOP EVOLUTION:  The convergence of roofing and energy technologies, by Guy Akasaki – Building Management Hawaii Feb/Mar 2012 issue read article) we naturally progressed into building integrated photovoltaics — suddenly taking the roof from a liability to an income producing asset.   While the credits and incentives are generous and and accelerated depreciation make the opportunity to “go green” an attractive offer, we continue to educate our clients on both the benefits of PV as well as the drawbacks that can come with less than professional installation.   A solar array requires penetrations to the roof.  Along with any penetration comes the risk of leaks and/or potential voiding of the warranty due to incorrect installation.  Also, most PV systems are warranted for 20-25 years.  You would not want to install a brand new PV system atop a roof that will be up for re-roofing in the near future and incur the additional cost of removal and reinstallation of the system – thus matching the life of your roof as close to the life of your PV system is ideal.  There are an array of roof top solutions that will deliver the most benefit to your building by addressing all related facets – possible energy savings, financial feasibility, existing roof condition, and hedging against potential litigation related to roof integrated energy solutions.
