North London Roofs Are Filling Up With Solar Panels — Here's What That Means for Your Tiles
Ask around Cockfosters or Whetstone this summer and you'll find at least one neighbour who's had scaffolding up for a solar install rather than a re-roof. Government figures released at the end of August show nearly 172,000 solar installations went up across the UK since the start of 2026, with almost 19,800 rooftop systems fitted in July alone – roughly one every two minutes of the working day. The South East and East of England, which take in a fair chunk of our patch through to Enfield Chase, are among the fastest-growing regions, both up around 14 to 15 per cent year on year.
What a lot of homeowners don't ask, until we're already up the ladder, is whether their roof can actually take it. A tiled roof laid with Marley Modern or Redland Regent needs its rafters and battens checked before anyone starts drilling in mounting rails, and on older Barnet and Enfield terraces we're regularly finding batten gauge that's tight or timber that's had sixty-odd years of London weather. K2 and similar rail systems clamp to the rafters through the tile, not the batten, so it's worth knowing where your rafters actually sit before a scaffold goes up.
Flashing is the other thing people forget. Any array that sits near a chimney or party wall abutment needs proper Code 4 lead dressed in behind it, not mastic smeared round the edge, because that's exactly where we get called back to fix a leak eighteen months later. On flat roof extensions – common enough on the Victorian semis around Southgate and Winchmore Hill – panels sit better on a ballasted frame over a fully bonded felt or single-ply system than screwed straight through the membrane.
The Warm Homes Plan due to kick in next year is expected to push funding towards rooftop solar for both social housing and privately owned homes, so this isn't a trend that's slowing down. If you're planning a re-roof anyway, it's worth having the solar conversation before the felt and battens go on rather than after, because retrofitting rails to an already-laid roof means lifting tiles you'd rather leave alone.
