Dorothy L. Corley, 82, who founded and operated a Prince George’s County roofing business with her husband, died Dec. 4 at her son’s home in Harwood. She had multiple myeloma, her son John Corley said.

Mrs. Corley had been a bookkeeper for Adams-Burch, a restaurant supply business, before she and her husband started the Corley Roofing Co. in 1959. She managed the accounting and office work for the company for many years before retiring in her 70s. Her sons now run the business, which is based in Temple Hills.

Dorothy Lee Hendley was born in Washington and attended Oxon Hill High School. She lived in Temple Hills before moving to Brandywine in 1991.

Her husband of 37 years, John A. Corley, died in 1984.

Survivors include two sons, Richard F. Corley of White Plains, Md., and John D. Corley of Harwood; a brother, William Hendley of Waldorf; five grandchildren; and two great-grandchildren.
