Solar Panels for Slate Roofs
Slate roofs need a different approach. Installation is more complex than plain or interlocking tiles— the fixing method, weatherproofing, and finish all have to be right.
We specialise in slate roof solar installations and only use dedicated slate hooks and flashing kits, such as Genius Speed Flash, to protect the roof and keep everything waterproof
Done properly, solar on slate is clean, secure, and looks great from the street.
How solar works on a slate roof
Slate roofs can’t be drilled and fixed the same way as standard tiles. Each slate has to be carefully removed, cut and replaced, with fixings installed beneath, and the roof made watertight with flashing kits again before any solar panels are installed.
We use specialist mounting hooks designed for slate, combined with Genius Speed Flash to protect the roof long-term. It’s a slower, more precise process — and that’s exactly why most installers avoid it.
Done properly, the system sits neatly on the roof, keeps its weatherproof integrity, and looks great.
This is where time and experience matter.

Why choose Greenway Energy
Slate roof solar isn’t a standard install. Each fixing sits beneath the slate, so everything has to be done carefully to keep the roof watertight and looks right from the street.
We take our time to ensure the installation is done properly and use dedicated mounting systems and slate-specific flashing like Genius Speed Flash to keep the roof fully weatherproof and maintain a clean finish.
