Moss in your Cobham gutters: why it happens and the real damage it causes Issues · 7 min read # Moss in your Cobham gutters: why it happens and the real damage it causes Moss in the gutter is a red flag, not a nuisance. Here is what it does to your Cobham home and how we clear it without ladders on your lawn. ## Where the moss comes from Gutter moss almost never grows in the gutter itself — it slides off the roof. A single Cobham autumn storm can drop 10–15kg of loosened moss from a mature colony straight into the gutter run, blocking outlets in a single afternoon. ## What blocked gutters do to a Cobham home Once the outlet is blocked, water backs up. On period brickwork common around the village core and Stoke d'Abernon, that overflow soaks the wall head, wets the wall plate, rots fascia and soffit, and eventually shows as damp on upstairs bedroom ceilings — which is very often mis-diagnosed as a roof leak. ## How we clear it We use a 40-foot carbon-fibre gutter vacuum operated from the ground — no ladders in flower beds, no risk to conservatory glass. Pole-mounted CCTV footage of the cleaned gutter is emailed to you the same day. ## Cost and cadence From £85 for a small Cobham semi, £130–£195 for detached. If your home is under mature trees, plan two clears a year (spring and late autumn). Otherwise once a year in October is enough. ### Get your free roof cleaning quote Fixed-price quote within 24 hours. No call-back chasing — we'll email you.
