How Will The Solar Panels Attach To My Roof?

This is a common question from homeowners. Our VP of Solar Production, Gailan Wensil-Strow, explains how we use the RT-MINI II to ensure panels are connected to your roof without causing any damage and maintaining your roof’s integrity.

The RT-MINI II

The RT-MINI II is a self-flashing base designed for mounting solar panels on various types of roofs, including asphalt, metal, EPDM, and TPO. The RT-MINI II is designed to provide a secure and waterproof attachment point for conventional rail mounting systems used in photovoltaic (PV) installations.

Key Features

• Self-Flashing: The RT-MINI II incorporates a self-flashing design, which helps prevent water infiltration and maintains roof integrity.
• Versatility: It can be installed on various roof types and attaches directly to the roof deck, eliminating the need for attic access or inter-rafter blocking.
• Strength: Engineered to withstand wind speeds up to 180 mph and ground snow loads up to 90 psf.
• Compatibility: Suitable for use with conventional L-foot attachments and various rail systems.
• Waterproofing: Uses RT-Butyl, a flexible flashing material certified by the ICC for waterproofing.

Installation and Benefits

• Quick Installation: Fastens with wood screws, eliminating the need for pilot holes and speeding up the installation process.
• Roof Warranty Preservation: When properly installed, it doesn’t damage the seal on asphalt shingles, helping to maintain the roof’s warranty.
• Flexibility: Can be attached to rafters, blocking, or directly to the roof decking, providing installation options for various roof structures.

The RT-MINI II represents an evolution in solar panel mounting technology, offering a balance of strength, ease of installation, and roof protection for residential and commercial solar installations.
