Brilliant roof cleaning from Coljack Team. We are delighted with the work carried out by George and his team. George and Dan cleaned our home roofs, gutters, external soft fascia and windows. They were extremely efficient, professional and clean. The transformation is amazing. Thank you.

Jason, George and Dan from Coljack did an amazing job at cleaning and treating the roof on my 1959s house. I wanted a clean roof before getting solar panels added and didn’t want moss lifting tiles or damaging my roof. Before they started the roof had around 50 years of moss and dirt on it, but the guys cleared it all thoroughly and carefully off using their special tools and equipment. They were super hard working plus they did a great job of explaining the process and happily answered any questions. They arrived promptly on time each day and were very professional & friendly. They did a careful and thorough clean and roof treatment, cleared and washed all the gutters/soffits and then washed the windows. They even did a walk round to make sure I was 100% happy and left everything super clean and tidy. The roof now looks like it is brand new and I’m super impressed with the service. I thoroughly recommend Coljack for cleaning and treating your roof - money well spent!
