Sunbank Installation Manual
9. Roof Attachments
There are many companies that make robust solar roof attachments. Roof attachments are specific to
the type of roofing to which you are attaching the Sunbank and all roof attachments should be
approved by a structural engineer for the specific installation. For mounting to most composition
shingle roofs, we recommend a flashed L foot design like the Quickmount QSME-Lag. Snap-n-Rack and
S-5! make metal roof attachments, Pegasus for tile roofs, and Chem-Link and Eco-Fasten have
products for flat or membrane roofs.
Spec sheets, distributor information, and installation diagrams can be found on their websites.
It is recommended to attach the roof attachments to strut rail (second set of photos) and then mount
the Sunbank bracket to the rail. Especially underneath the tank, where most of the weight lies. This
has the advantage of allowing the installer to put in more lagged roof attachment points, to spread out
the weight between more rafters, and to have the final mounting position not be constrained by rafter
position.
