Rake edge: The overhang of an inclined roof plane beyond the vertical wall below it. Random-tab shingles: Shingles on which tabs vary in size and exposure. Rebar: When concrete cracks it will separate or become uneven, rebar is a rod of steel placed into the concrete, usually in square feet one or two. Refill tube: On most toilets, a refill tube directs water from the Ballcock into the overflow tube to refill the bowl after the siphon break. Release tape: A plastic or paper strip that is applied to the back of self-sealing shingles. This strip prevents the shingles from sticking together in the bundles, and need not be removed for application.

Ridge vent: A single or continuous roof vent located at the peak of a gable roof Rim holes: A series of small holes, in the underside of a toilet rim, around the circumference of the bowl.
