We needed the moss cleaned from our roof and our builder recommended Pro-clean. We received a home visit and prompt quotation for the work. The scheduled date was postponed several times, sometimes at unavoidably short notice, as the work is weather-dependant, which we understood. The job itself took longer than planned which was slightly inconvenient, but the cleaning has enabled our builder to clearly identify broken roof tiles that are leading to internal water damage during heavy rain. We received an invoice for the quoted amount shortly after the work was completed. The roof is visibly cleaner now and we are satisfied with the work.
