Is there anything better than black exterior mastic (frame sealer) to
repair a foot long crack in a bitumen felt roof? The crack is near the
edge where there is a lip to control direction of water flow.

Some has used what is now hard grey stuff to repair some previous
blemishes in the tiles. It is subsequently cracked.

I repair my flat metal kitchen extension roof with a length off a roll of
grey foil with bitumen layer obtained from a roofing merchant. Heat from
a
blowtorch melts it onto the metal.

JOOI If the roof's metal, to what part(s) are you applying the
lengths of tarred foil?

Over the split in the metal caused by slates falling off the main roof onto
it, corner first.
