Installing solar panels on slate roof

What to consider when installing solar panels on slate roof

Are you looking at installing solar panels on slate roof​ but aren’t sure what the process is?

Most new build homes are built with tiled roofs, however there are millions of houses in the UK that use slate roofing materials. A slate roof can be a little more difficult than a standard tile roof but an experienced solar company will have no trouble installing solar panels on slate roof​.

How are solar panels installed on a slate roof?

The process for installing solar panels on slate roof is pretty much identical to installing on tiles. You should open up the roof and fix your brackets onto an exposed rafter. These are your roof anchor positions.

The removed tiles should then be cut around the positioning of the brackets. To ensure the roof is weatherproofed, a SolarFlash kit should be used. First, position the foam to the bracket drop then position the SolarFlash in the correct position. The remaining slates should then be repositioned, securing with a HallHook where neccessary; Position the Hallhook between the slates. Use the nail hole that positions the bottom hook at least 10mm up from the finished slate line. Slide object slate into position then using the hookpull, pull firmly until the Hallhook locates the base of the object slate.

What not to do when installing solar panels on slate roofs

We’ve already covered this in a previous post however it’s worth re-emphasing… You should never drill any roofing tile when installing a solar panel as it can have several negative consequences. Tiles may crack and they will lose their weather tightness causing leaks and voiding warranties.
