Which shingles are specifically used to cover the ridge board?

Ridge shingles are specifically designed for use on the top of the roof where two slopes meet at the ridge board. They serve both functional and aesthetic purposes. Functionally, ridge shingles help to protect the vulnerable area at the peak of the roof from weather infiltration. They create a barrier against rain, snow, and wind, ensuring that these elements do not penetrate and cause damage to the underlayment or the roofing structure beneath. Aesthetically, ridge shingles provide a finished look, completing the overall appearance of the roof by matching or complementing the other shingles used on the slopes.

In contrast, ridge rafters are structural components that form the peak of the roof but do not serve the purpose of covering it. Re-covering refers to the process of applying new roofing material over an existing roof, rather than a specific type of shingle. Ridge vents are ventilation products that help improve airflow in the attic space, but they do not cover the ridge board in the same way as ridge shingles do. Therefore, ridge shingles are the appropriate choice when it comes to covering the ridge board on a roof.
