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.

Flash band on top of bitumous mastic.
Use the flashband primer.
Best done in warm weather. Unfortunately.

Aluminium strip with about 2mm bitumen on one side. I have found it
very effective when it is used with the appropriate primer. It can
easily be moulded. I used it once to seal a circular downpipe going
through a flat garage roof. Very effective
