    Roof replacement

    Posted 6 days ago

    Quality roof replacement at my property by Alpha SG in July 2025 with excellent customer care from Rory. My roof inspection was carried out with diligence with identified problems pointed out. Scope of work was clearly explained. I am happy with the replacement roof . Thanks Rory.

    Replace a complete roof

    Posted 02 July

    We had water appearing in the kitchen ceiling. We got three quotes and chose Alpha because they appeared more knowledgable about the cause of the leak. - primarily due to poor condition of the primal felt which was over 100 years old. The house was empty when they came to start the job, Rory, the man in charge of the job, continually kept me informed all through accompanied with photos. I have a Ring camera and was able to see some of the work being carried out. The crew always arrived on time and were very polite to neighbours and passers by in responding to questions or requests.

    Gave quote, which I was happy with. Came with his team. Showed pictures before and after. They also noticed issues with my next door neighbour. Had a word with them show the pictures and was happy to have the work done. Have had no more leaks. They were prompt. Cleared up everything. Really pleased

    Fixed damaged tile

    Posted 04 June

    Very easy to deal with and had the roof repaired in no time. I’d tried a couple of other companies and had poor service with them not coming back to me. Alpha SG were the complete opposite. Would use again.

    5-Star Review for Rory at Alpha Roofing

    Posted 30 May

    Rory from Alpha Roofing was fantastic from start to finish. The job was fairly urgent and he responded immediately. He was friendly, honest and kept me informed throughout. His team were professional, fast and incredibly respectful of the house and tenants, no disruption and they left everything spotless. The work was completed to a high standard at a very reasonable price. I wouldn’t hesitate to recommend Alpha Roofing and will definitely use them again.
