Yes! That's reminds me I need to buy some more lap vents.
I was up there for a bit before I noticed so wondered if it was from the warm house air coming up through the open hatch but the top of the timbers did feel a bit damp so I suspect it had been there for a while. Not noticed it in warmer times. I have about 10 lap vents and two tile vents but going to buy another 20 lap for good measure.

Anyone had condensation appearing on the underside of the roof felt?
I imagine it’s due to the solar panel brackets that were recently installed and the extreme temps.
Is it something that’s probably only an extreme weather thing or something I need to sort with better ventilation / circulations?
