As befits a playhouse the T&G roof panels are pretty thin, and I am a bit reluctant to hammer clout nails in for fear of damaging them
The original felted roof had nails sized something like 3mm x 20mm from what I see in Screwfix. I am wondering if there is anything smaller, or less 'impactful', that I could use in this situation.
I have seen smaller diameter nails, but wondered if there is anything else - perhaps something that I could screw in, that would work with roofing felt? Happy to eg. put some blobs of sealant on top if that would help...
