victorian slate roof is letting in a very small amount of water in very heavy rain

My victorian slate roof is letting in a very small amount of water when it rains heavily and the wind blows in a certain way (in some bursts of heavy rain no water comes in). The actual amount of water is small (say 100 ml) and I have put a large plastic container in place to catch the water so it is not damaging the insulation. Certain timbers also get wet but they dry out within a coupe of days and feel structurally sound when I tested them with a hammer and nail. A local roofer suggested that the best fix (without putting a new roof on) was to apply a resin of about 1m x 1m over the area of the leak. Does this seem like a good fix? Given the leak is quite small and not happening very regularly this seems like a sensible first step before taking much more drastic and costly action. Assume this will not have an impact on ventilation overall as it would be a small area of a much larger roof. I have not seen any other leaks but only a third of the loft is floored so it is difficult to tell if there are leaks elsewhere. What do people think?
