Things You'll Need
Latex paint remover
Roof shingles are made of small pieces of stone and asphalt. They protect the wood underpinning from rain and keep water from getting into your house. If you get paint onto your shingles, you need to work fast to get the paint off. Allowing the paint time to fully dry means it will take you much longer and be much harder to remove the paint, and it also will add to the possibility that you might damage the shingles.
Wet a rag with paint stripper or paint remover, and blot the surface of the paint with the rag. Do not scrub with the rag, because that will damage the shingle.

Place several drops of rubbing alcohol onto the surface of the paint; use enough to completely wet the surface.
Cover the alcohol with plastic wrap, and tape the plastic wrap to the shingle to prevent the alcohol from evaporating. Leave the plastic wrap on the shingle for 30 minutes. This will liquefy the paint.
Blot the paint off the shingle with a clean rag. Again, do not scrub. Repeat the process until the paint comes off.
Clean the surface by blotting clean water onto the shingle.
