Shingles
Definition and meaning of Shingles in real estate.
Shingles are thin, overlapping pieces of building material installed in rows to cover roofs and exterior walls to protect them from rain, snow, and wind. They are laid from the bottom of the roof or wall upward, with each row overlapping the joints of the row below it.
In more detail
Shingles can be manufactured from a wide variety of materials, including asphalt, wood, slate, clay, and composite materials. Asphalt shingles are the most common type used on US homes because they are cost-effective, durable, and relatively easy to install. Higher-end materials like slate or cedar shakes offer distinct architectural styles and can last much longer, but they come at a higher price and may require reinforced roof structures due to their weight.
Home buyers should ask about the age and condition of the shingles, as a failing roof is one of the most expensive repairs a homeowner can face.

Frequently asked questions
How do I know if my roof shingles need to be replaced?
Signs of failing shingles include curling edges, cracking, missing pieces, leaks, and excessive loss of mineral granules in the gutters.
Can you install new shingles over old ones?
Some local building codes allow a second layer of shingles to be installed over the first, but stripping the old roof is generally recommended to inspect the sheathing beneath.
