Solar without a pitched roof.
Solar Panels on a Flat Roof
A flat roof does not rule out solar. Panels are mounted on frames that tilt them towards the sun, and a flat roof can sometimes offer more freedom in orientation than a pitched one, because the panels do not have to follow the roof slope.
This page explains how flat roof systems are designed and what we check before fitting one.
How panels are mounted
On a flat roof, panels sit on angled frames rather than lying on the surface. The frames are either held down by ballast, which avoids penetrating the roof, or fixed to the structure. The right method depends on the roof's load capacity, the covering and wind exposure.
Orientation and spacing
Because the frames set the angle, panels can face south even if the building does not. Rows must be spaced so one does not shade the next, which affects how many panels fit. East and west facing layouts are another option, spreading generation across the day.
Roof condition comes first
Panels stay on a roof for many years, so the covering underneath should be in good condition before installation. If a flat roof is near the end of its life, replacing it first is usually the better decision. Drainage must also be kept clear around the frames.
Extensions, garages and dormers
Flat roofs on rear extensions, garages and dormers are common candidates. They are often out of public view, which can help in conservation areas. Access for installation and maintenance is checked at survey.

Frequently asked questions
Can solar panels go on a flat roof?
Yes. Panels are mounted on angled frames, held down by ballast or fixed to the structure depending on the roof.
Do flat roof panels need drilling?
Not always. Ballasted systems avoid penetrating the roof, subject to the roof's load capacity.
Which way should flat roof panels face?
Frames let panels face south regardless of the building, or an east and west layout can spread generation across the day.
Should I replace my flat roof first?
If the covering is near the end of its life, replacing it before installing panels is usually the better decision.
Will panels on a garage roof work?
Often yes. We check the structure, shading and access at the survey.
