The subflashing at the roof deck forms a waterproof shield isolating all penetrating fasteners from water intrusion. 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 installations.

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 .
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.

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.
