QBase Universal Tile Mount
The QBase Universal Tile Mount uses the QBase foundation and two spun aluminum cone flashings for installing solar panels on tile roofs with superior strength and waterproofing. The installer can conform the secondary top flashing to fit virtually any roof tile, flat or curved.
The primary flashing at the roof deck forms a waterproof shield isolating all penetrating fasteners from water intrusion. The top flashing is malleable, so it works equally well for curved and flat tile roofs. Both flashings feature a spun aluminum cone, with no seams to fail in extreme climates. The reinforced QBase makes an extraordinarily strong foundation. Ideal for both retrofit and new roof solar panel installations.
Available in aluminum mill finish.

Installing the QBase Universal Tile Mount
Waterproofing Technology for Tile Roofs
Tile Roof Waterproofing Methods
All Quick Mount PV tile mounting products are designed to comply with the roofing best practices listed by the Tile Roofing Institute (TRI) for tile penetration flashing (MC-02). The photos below show our QBase Universal Tile Mount. The same waterproofing methods are recommended for all of our tile mounting products. For more info go to www.tileroofing.org or contact firstname.lastname@example.org.
If permitted by the building inspector, the three-course method may be an option for waterproofing the deck flashing. This process uses a layer of asphalt roof cement (approved by the roof manufacturer), a layer of reinforcing fabric, and another layer of asphalt roof cement to seal the flashing to the felt paper. Click here to download step-by-step instructions to use the three-course method with our tile roof products. (PDF 617K)
Felt Paper Bibbing Method
In retrofit installations where the standoff and primary flashing do not fall in a position that is close to the overlap of felt paper, an approach that is sometimes called “bibbing” can be used. When the overlapping drip edge of the felt paper ends in the tile course above the penetration, a separate piece of felt paper is positioned under the battens and overlapping felt, which then extends down to bib around the penetration and over the deck flashing.
UL 2703 CERTIFICATION
All IronRidge Systems have been listed to UL 2703, the standard for evaluating solar mounting systems. This ensures they maintain strong electrical and mechanical connections over an extended period of time in extreme outdoor environments.
IronRidge products come with a 25-year warranty, guaranteeing they will be free of defects in materials and manufacturing which materially impair the use of the products for the purposes for which they were designed.
