You'd better take Barry's advice as he has been in the roofing trade for 30 years. I only have 27 years experience in investigating why guys with thirty years expeience still can't install a roof system correctly. What's your problem with salt and pantyhose ? It will temporarily solve your problem and won't cause damage to the roof.

In any case, I am available to discuss roofing, ventilation of the roof (which is the root of the problem), secondary protection through flashing, eave protection, or whatever.... but I don't like pissing contests, so perhaps you should not get your pantyhose in a knot and follow the advice offered by others.
