There’s a lot of information out there on this project—maybe an overwhelming amount during the first stages of considering roof repair or replacement.(Image: https://media.defense.gov/2024/Sep/10/2003542385/-1/-1/0/240910-F-GD062-3003.JPG) However, the information comes in handy when it comes time to make informed decisions about maintaining a roof.

Shingle cost is quoted on a per-square basis or often a roofing-square basis (100 square feet is considered a roofing square).(Image: https://upload.wikimedia.org/wikipedia/commons/b/b2/Ashdod_20052C_rooftop_view_p2.JPG)
