What was the roof problem?
Dave records this job as manual moss removal. These photographs were taken at the biocide stage of the work, so they do not show the moss on the roof.
What did Moss Men do on the roof?
After manual moss removal, Moss Men spray a biocide, Pureseal Bac Clear Pro, at about garden-hose pressure. Both photographs show a yellow hose across the slope, which fits that spraying, and the biocide in pale patches and streaks on the tiles.
What do the roof photographs show?
The first looks down the slope from beside the verge, and the second looks across the tile rows towards the ridge. Both are labelled During: the pale patches on the tiles are biocide, sprayed as part of the work. Neither shows the roof when the work was finished.
How can you ask about your roof?
Each roof is looked at on its own before we recommend a method or discuss the likely result. A past job shows what was done on that roof; it does not predict the result on yours.
Send your address, the roof concern and photographs taken safely from the ground, if you have them. Include any restricted access, previous repairs or property requirements you know about.
