Moss removal and roof cleaning
West Wales roofs grow moss readily. On a north or shaded slope it can hold water, lift the edges of tiles, block valleys and overload gutters. Summit Roofing carries out moss removal and careful roof cleaning, and will also tell you when the covering underneath is the real problem.
Why moss is more than a colour change
A green film is often harmless. Thick, established moss is not only unsightly: it keeps the surface wet, can work under the nibs of concrete tiles, and sheds into gutters and valleys after dry spells. On slate it can hide cracks. Cleaning has a maintenance purpose, not only a kerb-appeal one.
Method matters
A roof is not a driveway. Aggressive blasting can strip the surface of concrete tiles, drive water under the laps and shorten the life of a covering that was otherwise sound. We work with methods suited to the material, and we tidy the gutters and downpipes as part of taking the growth off, otherwise the problem simply moves to the hopper.
Treatments and expectations
Where a biocide or similar treatment is appropriate after removal, we will say what it is for and what it will not do. No treatment turns a porous, frost-damaged or end-of-life tile into a new one. If cleaning would only reveal a covering that already needs repair or replacement, that is the conversation to have first.
Trees, shade and coming back
Roofs under trees or on permanently shaded pitches will grow moss again. Cleaning is maintenance. If a valley or gutter is chronically blocked by a neighbouring tree, we can say so; we cannot alter someone else’s trees without the right permission.
