QBase® Low Slope Mount Installation & Flashing Guidelines BI 7.2.
Low Slope Mount Installation & Flashing Guidelines The Quick Mount PV Low Slope Mount is one of the strongest mechanically attached standard solar mounts available. The aluminum QBase® post has a 50 year life and is warranted to 20 years. The Low Slope Mount is available in 7", 9" and 12" heights and works on the low slope roof types below: Single Ply Membranes • • • TPO PVC EPDM (rubber roofing) Asphaltic Roofing • • • BI 7.2.
QBase® Low Slope Mount Installation Instructions WARNING: Quick Mount PV products are NOT designed and should NOT be used to anchor fall protection equipment. Installation Tools Required: Drill with 7/32'' bit, impact gun with 1/2'' socket, 1 tube of sealant compatible with roofing materials, pencil, chalk line 1 Locate the desired mount placement over a rafter (or custom wood blocking). Using the base as a template, mark the two penetration points with either a pen or light drilling.
Working On Insulated Membrane Roofs For membrane roofs with insulation, remove the membrane insulation with a hole saw or suitable cutting tool. Bolt the QBase® with attached post directly to the deck or rafter using two lag bolts. Drill pilot holes directly into to the deck or the rafter. Re-insert insulation around post before sealing hole with flashing. 4 BI 7.2.
Single Ply Membrane Flashing Please note: Building code requires flashing per roofing manufactures instructions. Single Ply membrane typically requires that qualified roofers install flashings using heat welded or chemically welded flashing from approved suppliers, but other solutions can be used depending on circumstances. TPO • • Heat welded flashing purchased from roofing manufacturer. Chemlink E-Curb PVC • • Heat welded or chemically welded flashing purchased from roofing manufacturer.
Asphaltic Roofing Material Flashing Modified bitumen membranes typically require that a qualified roofer install metal flashings using torch down the method shown below, but other solutions, including Soprema ALSAN flashing or Chemlink E-Curb can be used depending on circumstances.
Chemlink E-Curb Flashing Installation Instructions Find more information at www.chemlink.com/index.php/chemlink-products/e-curb-system. E-Curbs are designed for use on granulated modified bitumen, asphalt and coal tar B.U.R. (built up roofing). E-Curbs are specified for PVC, PIB, and TPO single ply roofing membranes. E-Curbs are highly versatile for sealing penetrations around solar panel mounts, HVAC, electrical, and any type of structural supports. TPO Primer is required for use with TPO.
Soprema ALSAN Flashing Installation Instructions Find more information at www.soprema.us. Clear away all debris around the mount. Apply roof compatible sealant in a square around the mount where the flashing will be placed. Place flashing over mount and nail down at each corner of the flashing. Scuff up the surface of the flashing with sandpaper. Apply a base coat of ALSAN over the flashing, overlapping the edge of the flashing by at least 4".
