Flat roofs

September 18, 2017

Flat roofs (also called low-slope roofs) are equally compatible with solar as pitched roofs. The materials used to cover flat roofs vary widely, and solar can be installed on almost all of them. The three main racking arrangements for flat roofs are parapet-to-parapet wall mounts, ballasted racking, and standing seam clamps. In parapet-to-parapet wall mounts, aluminum beams are attached between the two parapet walls of the home or building. The beams provide a structure upon which you can lay the panels and clamp them down. In ballasted racking, panels will be connected directly to the roof and tilted upwards at the appropriate angle. In these cases, non-penetrating hardware secure the panels to your roof via weighted blocks. For flat standing seam metal roofs, clamps are used to connect the standing seam of the roof to a series of aluminum rails, on top of which you attach the panels.
