Repair roofing felt from inside loft

We are talking about the under tile felt or "sarking" here are we?

If so I would have thought that ordinary felt adhesive would do the job with a piece of underfelt as a patch. You could also probably use "torch on" felt if you are feeling brave enough to wield a blow torch in the loft (make sure you have a fire extinguisher handy though!).

You need a bitumen based roffing felt adhesive as used to stick down roofing felt.

I take it you mean the sarking? Shouldn't worry about it too much unless water is getting in but that would indicate a more serious problem with the primary roof covering...

You don't really want to just "stick a patch on" water will collect behind it. / Sarking> /g/ // < patch // --/ // patch > // < sarking L// //

With good overlaps you don't need any glue just clout nails through the felt into the rafters each side. This works, BTDTGTTS, using old feed bags as patches during a F8 Gale when the slates where off the barn roof and the old sarking was getting torn to shreds.
