The RT-MINI II with AlphaSeal™


The RT-MINI II is our most popular residential roof mount base featuring Roof Tech Inc's Self-flashing AlphaSeal™ PV Mounting Technology. The RT-MINI II is designed to attach conventional rail mounting systems for any sloped roofs consisting of metal, EPDM, TPO, and asphalt. 

The RT-MINI II has more mounting options for rafters and also combining rafter and deck attachments. The optional RT 5 x 90mm stainless wood screws (rafter only) can provide a wider span, and the offset rafter mounting adds more options on any style of roof and pitch. The new design uses less aluminum, making it a more efficient design that reduces raw materials and decreases logistic expenses.

RT-MINI II is engineered to withstand wind speeds up to 180 mph and ground snow up to 90 PSF. The main difference between RT-MINI II and conventional flashing is the faster installation time because RT-MINI II is fastened with wood screws, eliminating the need for pilot holes. As a result, there is no damage to the seal on asphalt shingles. RT-MINI II is fully waterproof and certified by the International Code Council (ICC-ESR 3575). Stamped PE letters are available for 40 states in the U.S. and five provinces in Canada. The RT-MINI II is also Florida product approved for all HVHZ projects!
