I could not get onto the roof so just applied on the inside to seal the areas where water penetrated, usually between the roof board joints which the felt sits on top off and is just the easiest entry point for water. Very sticky stuff so force into gaps with spatular or brushed around rusty nails/knots etc. Monitor next heavy rain then do same lower down if required and works a treat. Not a permanent fix but has held for several months.
Absolutely brilliant product

I bought this to repair an old roof and I was gobsmacked at how well it worked. The roof looks brand new. It was easy to use and the finish was excellent.
