Business advisers and accountants Scott-Moncrieff were called in last Wednesday after contract losses and cash flow difficulties.

Provisional liquidators Stewart MacDonald and Pamela Coyne have said they are following up interest from potential buyers.

However, former Miller Roofing employees are blaming the “heartless” management that took over in 2007 for the recent collapse.

One man, who did not want to be named, said: “Everything went downhill when the new management took over a few years back. I’m worried. I’ve been there for nearly 20 years and now I have to find another job. “There are still unfinished contracts — the one I was on is incomplete. We also had jobs at the Southern General Hospital working for big firms. I don’t know what’s going to happen to them.” Miller Roofing has been trading in Clydebank since it was set up in 1984 by Stuart Miller.

New management took over seven years ago, with director Alan Hilditch appointed as managing director.

Many workers have been left devastated after the shock news hit them last Wednesday.

Another man, who was employed for more than 20 years, said: “I have some very fond memories until it was taken over by heartless men who were in it for themselves from the offset, unlike Stuart who treated us like number one.

“I am now like loads of others who used to work there — with a mortgage and other bills to worry about.” Clydebank MSP Gil Paterson said: “The collapse of this company is a tragedy at many levels. It is a loss for the owners, the workforce and for Clydebank where jobs are so desperately needed.

“It is very sad news indeed and my sympathies are with everyone affected.” West Dunbartonshire MP Gemma Doyle said: "I'm extremely sorry to hear about the problems at Miller Roofing and deeply sorry for those facing the prospect of redundancy, especially when some of the workforce have been with the company for a long time.

"I hope a buyer can be found and that the jobs will be saved."

A Scott-Moncrieff spokeswoman said: “Miller Roofing Ltd, having traded from its base in Clydebank for the past 30 years, has unfortunately had to appoint provisional liquidators. “The company had traded successfully since a management buyout in 2007 but recent contract losses and cash flow difficulties made it impossible to continue in its present form.

The joint provisional liquidators, Stewart MacDonald and Pamela Coyne, advise that interest has been noted from potential buyers.”
