To prevent this from occurring a chimney should extend at least 3 feet past a flat roof and be at least 2 feet above any roof peak within a 10 foot radius. The stovepipe connects the stove to a chimney pipe which extends through the roof. A single wall stovepipe requires more clearance than a double walled stovepipe. The first is known as an air cooled chimney system.

As the name implies air cooled systems use air for cooling. The structure of the flat roof is wood combustible and the covering is single ply pvc.
