I strongly recommend you never use McDermond Roofing.
I have used McDermond to re-roof a small iron roof and while they were prompt and seemed competent at the quotation stage, once I accepted the quote and paid the deposit everything fell to pieces.
I was told the work would be scheduled within six weeks of paying the deposit which I paid in January as I wanted to get the job done during summer, and that it would take no more than a week to complete. Five months later and the job still isn't complete. I had to chase the company up a number of times and nobody kept me informed as to when the job would be done. There has been issues with sharp pieces of metal and screws etc left lying around the site. The roofers managed to drill through and damage the ceiling of the house. The house isn't weather tight as a cap on a ventilation shaft has been removed and not replaced even after informing the roofing manager who assured me it would be done the next morning. A car was damaged by the roofers who dropped iron on it.
I have been back and forth to the roofing manager a number of times who always assures me the issues will be sorted straight away and then nothing happens.
It is beyond a joke and I hope to spare anyone else the stress, hassle and anger of dealing with this company by posting this review.
