The churches, some dating back to the 19^th century are getting timely overhauls thanks to state government Heritage Council funding and money raised in the community.

While the coronavirus has stopped church services across NSW, it was the threat of falling slate tiles injuring parishioners that forced the closure of the Holy Trinity Anglican Church on the corner of Anson and Byng streets last year.

The rector, Fr Mal Dunnett, said work was now underway to replace about two-thirds of the roof.

"The whole section that needs to be replaced is being replaced," he said.

Fr Dunnett said the work was part of a $1.2 million project to renovate the church and its historic bell tower.

He said the Holy Trinity Foundation had driven the fund-raising.

"It has been a substantial task. It will be good. The slate is guaranteed for 50 years. It was over 100 years old," he said.

"It will outlive all of us."

Fr Dunnett said they were hoping to have the work completed by July.

"It will be another six-seven weeks," he said.

Fr Dunnett said they planned to celebrate the completion of the works, and hopefully allowing for the removal of coronavirus social distancing rules, the resumption of services in the church.

"It is our intention to throw a big party," he said.

The church has been surrounded by barricades for several months after it was ruled too dangerous for the public to be near it.

The congregation had been meeting in the church's memorial hall until that too was stopped by Covid-19 rules.

Ernest Shave, secretary of the church's National Trust Foundation appeal, last September said, about 12 tiles had slipped down to a gutter after years of wintry weather had rusted the metal cleats that held the tiles down.

Fears of them falling further closed the church. "They are like an axe, it would chop your head off," he said.

There will be reports on the other church restorations in future editions of the Central Western Daily.
