There were reports of water ingress effecting an industrial premises so our gutters team were sent to investigate. The building had gutter guards so not much debris in them. Where there was debris removed gutter guard and cleaned. Managed to access area on roof where slates had slipped and could be the cause of ingress. Unable to reach 1 tile with MEWP.
Gained access to building roof
Sealed some splits on valley, this looks like it may have been repaired previously.
