North Wales weather is generous with rain, and Denbigh's roofs pick up moss and algae as a result, particularly on shaded or north-facing slopes. A build up left untreated for several years can trap moisture against tiles and shorten their lifespan.
Most jobs start with moss removal before a softwash treatment lifts remaining algae and grime from the surface of the tiles.
Roof cleaning prices depend on roof size, access, and whether the work is a manual scrape and biocide treatment or a full steam clean. A modest semi-detached roof with easy ladder access will typically cost less than a large property needing scaffolding.
Bark also connects homeowners with roof cleaners working in Prestatyn, Rhyl and Ruthin, so if you're open to a slightly wider search you may find more tradespeople to compare. Post your job details once and see who's available.
