As a contractor I usually use a product made by Gilsonite. This product is marked on the can for professional or industrial use only. I'm not sure if the general public can get it. They are asphalt coatings that are either emulsion or solvant-based.

Asphalt emulsions are highly recommended for most circumstances, especially under reflective coatings. They are solvant-free and have great stability, longevity and freedom from flow or sag regardless of slope or temperature. As they are water based they require adequate time to dry before exposure to rain or cold temperatures.

Solvant-based asphalt coatings have high penetration and are recommended on old dried out roof surfaces or where there is threat of rain or very cold temperatures before an asphalt emulsion could cure.

As far as products available to the public I saw some stuff at Lowes that I believe is also available at Home depot called Snow Roof that had some elastormeric properties that would probably work for you. These are roof coatings and not for patching. You don't need to coat your whole roof but you'll want to coat the whole problem area from the top down to at least where the problem is occurring.

As far a spray stuff in a can, sounds like the truck bed lining stuff I've seen at Shucks Auto Supply. Might be a bit rinky dinky but for a nonprofessional trying to save some money, something like that stuff might work out for you but you are your own ginny pig here and I have no experience or knowledge of any roofing product that comes in a spray can. I imagine its probably a temporary solution.

Hope this helps,

use a roofing cement and a fabric, apply directly to whole,do not coat the whole roof with a asphalt base material it will do only harm unless there are to many holes and then you should replace I do not know were this concept got started but if you ask the makers of tin they will tell you the same thing. (Follansbee)Use a water bmetal paint ad primer.
