Can I Install Solar Panels on a Flat Roof?
Yes — the flat roof's PV (the ballasted — the tilted; the attached — the penetrating) is common: the structural (the ballast's — the weight; the wind's — the uplift; the engineer's — the letter), the fire (the setbacks — the 3-foot; the pathways'), and the roof (the warranty's — the preserved; the drainage's — the maintained). The flat's — the ballasted's advantage; the wind's — the engineer's check.

The structural check
The ballast (the 3-7 psf — the weight's; the capacity's — the verified), the wind (the uplift — the corners'; the ballast's — the sliding), the drainage (the maintained — the slope's; the ponding's — the avoided), and the engineer's (the letter's — the existing's; the stamped).
The racking types
The ballasted (the tilted — the 10°; the non-penetrating; the warranty's — the preserved), the attached (the penetrating — the flashed; the uplift's — the resisted), and the fire (the setbacks — the 3-foot; the pathways — the ridge's; the labeling).
Roof and economics
The warranty (the membrane's — the preserved; the manufacturer's — the approved), the age (the 10-year — the remaining; the reroof's — the first), the shading (the parapet's — the modeled; the setback's), and the production (the tilt's — the 10°; the soiling's). The flat roof's — the ideal's; the structural's — the verified.
The bottom line
Flat-roof solar works with ballasted (3-7 psf) or attached racking — get a structural letter for ballast + wind uplift, maintain drainage and roof warranty, observe 3-ft fire setbacks.
