Mark Dickson Roofer and Slating

Good- Replaced the felt on my shed roof without issue. Bad- Removed the moss from the front half of my roof with a power washer. I had read mixed opinions on doing this and didn't realise it was happening until they'd started. However, I figured they knew what they were doing (they're a roofing company after all) and I did admit the roof looked good afterwards. That being said, all I wanted was the moss taken off and not the entire roof cleaned, should have said something at the time but chalk that up as a lesson learned. Come the first heavy rain though and I come home to a wet patch on my bedroom ceiling. Looking into the loft showed numerous wet patches all over the power washed half of the roof (untouched half was dry). After Mark returned 3 times to attempt to 'fix' this, wet patches still appeared and he stopped replying to my texts. Him going up the ladder with a silicone gun on the 3rd occasion should have spoken for itself. Don't repeat my mistakes, AVOID.
