Rack your system, not your brain. PV solar racking systems shouldn't be a puzzle, with a pile of hardware and no help with the engineering.
RoofScreen gives you a complete kit, neatly packaged with pre-assembled parts. There are no questions about which part goes where. Here's what else you get:
• Watertight roof attachment
• Engineering and AutoCAD included
• Stronger frames, fewer penetrations |

Solar Rack Industry Comparison |
|
RoofScreen Solar Rack |
Other Racking Systems |
Ballasted Systems |
Roof Attachment |
Watertight industry approved penetrations.
Fewer mounting points.
Adjusts to roof pitch.
Patent pending Sprocket Lock creates rigid frame and reduces stress on the roof framing members. |
Waterproofing left up to installers to design on the fly often resulting in chronic leaks.
Weaker connection requiring many more penetrations. |
Many ballasted systems still need attachments into the roof system at some interval. These penetrations are often done incorrectly resulting in chronic leaks. |
Effect on Roofing System |
Small footprint allows water and debris to flow through.
Approved by major roofing material manufacturers.
Works with all types of roof systems. |
Relies on caulking and sealants, which leak over time. |
Creates depressions in roof causing roofing to deteriorate.
Blocks water flow.
Relies on mastics and adhesives.
Prevents access for maintenance and repairs. |
P.V. Panel Efficiency
|
Elevated frames allow air flow around PV panels.
Adjustable design allows installation at correct angles and pitch. |
With a high number of attachment points, placement options are limited, reducing the ability to set to proper angles. |
Reduces air flow lowers efficiency.
Reduced angles and pitch lower efficiency. |

Maintenance |
Roofing fully accessible for maintenance and repairs.
Racking and hardware fully accessible for maintenance and repairs. |
Requires more frames, reducing accessibility. |
Roof not accessible. |
Roof Usage |
Fewer frames and attachment points allow system to elevate over rooftop equipment resulting in higher density of usable space. |
Reduced density due to inability to span over larger rooftop equipment. |
Can only be used on wide open roofs with no equipment or pipes in the way. |
Installation |
Fewer frames equals less installation time.
Parts shipped in assemblies for fast installation.
Simple tubular design with telescoping fittings allows for unlimited adjustment during installation.
Framing elements (tubing) pre-cut at factory to allow for roof pitch and slope. |
Many nuts, bolts and hardware pieces to assemble and install.
Limited adjustability during installation.
Longer elements require field cutting resulting in more labor and material waste. |
No major challenges for this type of installation. |
