The Integrated Commercial Solar Solution
Combining Roof Mounted PV With Spray-In-Place Polyurethane Foam (SPF) Roofing
Our network of roofing contractors works with solar installers to provide a robust and economical commercial solar package made up of 3 components:
- A spray-on polyurethane foam (SPF) roof
- A photovoltaic (PV) system
- An energy monitor

Until now, commercial rooftops provided no revenue stream and indeed incurred costly repairs and periodic replacements.
ElectroRoof™ "electrifies" these roofs with PV arrays and adds a high-quality, thermally insulating, long-term roofing system.
ElectroRoof can guarantee both the roof and PV array for 20 years. ElectroRoof also provides electrical metering for billing, maintenance, and educational purposes.
Spray-on Polyurethane Foam Roofing
We install cool, solar-reflective roofing with a layer of foam offering significant insulation. This seamless waterproof product can be installed as a reroofing or new construction roofing system and will usually last the life of the building.
It is lightweight and significantly reduces HVAC expenses over conventional roofing products.
- HIGH INSULATION VALUE The foam component adds an R-value of 7 per inch of foam thickness.
- REFLECTIVE The coating component is bright white so it reflects the sun’s heat instead of absorbing it.
- SUSTAINABLE Design life of system is over 30 years before a recoat. Full warranty period is 20 years.
- GREEN BUILDING MATERIAL The energy savings from an insulated roof can yield 100% payback in as few as five years.
- SEAMLESS SPF has no joints or seams (or the heat and water leaks associated with them).
- ECONOMICAL An SPF roof is cost effective when compared to traditional insulated roofing methods.
Photovoltaic Array
Using PV makes it possible to tap into a limitless, pollutionfree energy source and protects you from electric price spikes, brownouts, and peak pricing.
Either crystalline or thin film panels can be used. The thin film panels are recommended if roof weight load is a limiting factor.
- ELECTRICITY Photovoltaic (PV) panels convert the sun’s energy to electricity.
- RELIABLE Solar panels are rugged and have a life expectancy of over 25 years. Guaranteed for 20 years.
- NO LEAKS There is no roof penetration. The panels can be mounted directly on the roof or racks are mounted on brackets which are foamed in place.
- ENVIRONMENTAL BENEFITS The panels are a renewable energy source that produces electricity with no byproducts or waste.
- POWER INDEPENDENCE Using PV protects your company from brownouts, price spikes, and rate increases.
View power every 15 minutes. View energy daily, weekly and monthly.

Resource Monitor
The rMeter monitoring system prepares real-time graphs viewable from any web browser and also provides climate data.
- MONITOR solar irradiance, power generated, power used, power purchased in dollars, kWh, carbon dioxide saved, barrels of oil equivalent.
- ACCESS your data in real time from any web browser. Graphs can be put on your own website. Raw data can be downloaded for your own analysis.
- EDUCATE about how much energy you are using. See the peak usage times and relate that to energy produced by the solar panels.
- VERIFY the energy produced from the sun and how much money it saves.
- MAINTAIN your system with quick alerts that identify problems. Troubleshoot from a web browser.
- BUILD public awareness with data that confirms your environmental commitment. Monitoring System

Before this new 25,000 Sq. Ft. commercial building was fitted with a 36,000 watt PV system as a part of the tenant improvements, Fiberglass Reinforced Plastic (FRP) blocks where lag bolted to the roof joists before the SPF Cencoat roof system was installed.

The Solar-Ready Roof
The energy manager of a building sees the roof as a great place to generate some electricity using photovoltaic panels!
The maintenance manager sees a photovoltaic installation as a roof maintenance nightmare. He sees lots of leaks waiting to happen and a nearly impossible re-roofing project half way through the expected performance life of the PV installation.
The maintenance manager can relax and enjoy reduced roof maintenance and the energy manager can have his money saving PV installation when they install an SPF (sprayed-in-place polyurethane foam) Cencoat roofing system in conjunction with their PV panels.
There are four easy steps to the Cencoat system:
- Identify and resolve design shortfalls or code issues including
the building's ability to support the additional weight of the PV panels.
- FRP (fiberglass reinforced plastic) blocks are lag bolted to the roof support members. This proprietary use of FRP was developed by CCC and has been used on hundreds of roofs to support all kinds of roof mounted equipment with 100% successful performance.
- A minimum of one inch of SPF is installed over the entire roof surface encapsulating the base of the FRP blocks and tapering up around them to create a perfect waterproof seal.
PV racks mounted on FRP blocks, which have been Lag Bolted onto the roof joists and foamed in place.

- The Cencoat Coating System, consisting of multiple passes of acrylic coating, with granules in the top coat, is installed. Bright white coating and granules qualify the roof for "Cool Roof" credits and rebates where applicable.
Cencoat roofs have proven performance beyond the 25 year warranty period of the PV system.
The combination of energy producing PV and an insulating SPF roof may even result in turning your building into a "net energy producer!
