The founder of the eponymous firm of chartered surveyors has died aged 73 after a period of illness.
He passed away last Friday and leaves his wife Carol and daughters Sarah and Victoria.
A statement from Manchester-based Roger Hannah said: “We announce with immense sadness the death of our friend and founder, Roger Hannah.
“The past few years have been difficult for Roger and his family as he struggled with declining health.
“Our thoughts and prayers are with his family and friends at this time of sadness and loss.”
Based at Parsonage Gardens in Manchester, the business has been involved in some significant developments over the years, including the acquisition of land for the Commonwealth Stadium in Manchester, and supporting the delivery of the London Olympics and Crossrail.
Simon Cook, managing director at Roger Hannah, said: “Roger Hannah started our business more than 40 years ago and was a highly respected chartered surveyor, a man of huge integrity, unrivalled tenacity and a devoted family man.
“Our deepest condolences go out to Carol and the family.”
