The roof the trade turned out for.

I cannot recommend this company enough. All solid hard working lads and the best in the business. They will be forever my go to roofers. My elderly parents were recently scammed of £18,000 for a new roof from another cowboy company and the family turned to Cormack Roofing for their advice. The work from these other people meant that it had to be redone from scratch. Tommy called on the roofing community for their help and arranged skips, scaffolding, roofing supplies and an army of lads who all volunteered to help 2 pensioners in dire need of help. The new roof is expertly done and the family are so grateful for everyone’s help, all thanks to Tommy and his workers. I would not hesitate to use Cormack roofing as my go to for any future work needed by myself, friends or family. We are so grateful for everything they have done.

This company came out to a relatively small job for them. Rain Water spilling out of the top joint of the down pipe. We have been trying to get someone out since last October. Let down after let down….. until we contacted Cormack roofing. Found them on a Knowsley group with good recommendations so contacted them, sent a video of the problem. They came out within a couple of days and identified the issue immediately! The bottom of the pipe was blocked with mud so rainwater wasn’t draining out. He charged £20 and there was 3 men! I would recommend him to any friends or family now. Very honest and knows his stuff.

I’ve used this company many times & would never consider using any one else. I recommend them to anyone in need of roofing. Always had a brilliant job at a really competitive price, all done by an amazing friendly bunch.

Cant recommend Cormack Roofing highly. We had a leak which was coming through to our new bathroom and they came out the next day and removed the chimney stack which was causing the leak due to loose bricks and the lead coming away. They did an excellent job and will be using for future work and would recommend to all friends and family..
