Portsmouth Roof Guide
Portsmouth housing is mostly dense Victorian terraces, interwar semis, and post-war housing across Portsea Island, with slate and clay tile on the older terraces, concrete tile on later housing. Here is what that means for solar.
Pitched Tile Roofs
Concrete and clay tile roofs are the most common solar substrate in Portsmouth. What the installer checks and where it gets complicated.
Slate Roofs
Natural slate is common across Portsmouth's older housing. It works well for solar, but it is less forgiving than tile.
Flat Roofs
Ballasted and tilted frames on flat roofs — how they work, and the two things that decide whether it is viable.
East-West Roofs
Splitting an array across east and west slopes — why it often beats waiting for a south-facing roof you do not have.
In-Roof / Integrated Systems
Flush-mounted solar that replaces the roof covering rather than sitting on it — and when it is the right call in Portsmouth.
Shaded Roofs
How shading really affects a solar array, what panel-level electronics can and cannot fix, and when to say no.
Listed & Conservation Area Homes
Planning, permitted development and discreet design for protected properties in Portsmouth.
