If the roof cleaning at your Downderry property has started looking tired, you're not alone. Bungalows take the worst of it because there's nowhere for water to go but the wall itself. Downderry sits in Cornwall at PL11, close enough to seaton that we regularly share visits.

Cliff-edge coastal village between Rame and Looe, which shapes how roof cleaning on painted render and pebbledash and Cornish slate and concrete tile actually plays out around PL11. Working out of PL11 we're rarely more than 13.7 miles from a Downderry job.
Most enquiries we take are from owners who've been thinking about it for a while and finally caught the right week for the weather. We aim to send the written quote inside the same evening you get in touch, and we don't chase you afterwards. The single most common feedback we get is that the invoice matches the quote exactly. The van carries hot and cold, softwash rig, vac pole and full drain protection so most jobs don't need a return trip. Detergents are biodegradable and lawns are pre-wetted before biocide goes near anything green. Cameras go on the vac pole as standard so you see the gutter before and after, not just take it on trust. Parking is where a lot of jobs go slow, so we ask about it up front rather than turn up and hope. Water usage is metered and quoted realistically — we never charge for water we didn't use. Pressure washing patios always finishes with a lawn edge tidy so borders don't end up sanded. Downpipe inlets are water-tested before we leave, not just visually checked. Copper sulphate never touches a roof we clean — it stains tiles and kills nothing worth killing. Runoff is diverted with drain bungs where soakaways feed straight into wildlife ponds. The most expensive part of any softwash is time on site, not the chemistry. For historic properties we send a method statement covering exactly what will and won't be used. The wall pump gets calibrated at the top of each visit, not once per job — it drifts otherwise.
Most Downderry properties we treat have painted render and pebbledash walls and a Cornish slate and concrete tile roof. That changes a few of the choices we'd make.
Aluminium roof ladders sized for the pitch typical of Cornish slate and concrete tile - noted across Cornish slate and concrete tile - the difference between a two-year finish and a five-year one.
Manual scrape and bag - moss never flushed into the gutters on your coastal village property - noted on cliffside bungalows stock - one of the calls we get most in the wetter half of the year.
Full-pitch biocide softwash via low-pressure boom across Cornish slate and concrete tile - noted at very exposed exposure - a job with a proper written scope, no verbal add-ons.
Solar arrays worked around without disturbing fixings - common on newer Downderry builds - noted in the Cornwall Council patch - still small enough to fix in one visit, big enough to be worth doing.

Slate roof under tree cover
Heavy lichen and moss — manual scrape over two days, biocide finished it.
Older clay tile + Victorian valley
Valleys cleared by hand before any softwash went near them; no debris pushed into the gutter system.
roof cleaning isn't urgent until it is. Catch it on the way down and the price is small; leave it for a fourth winter and it becomes a project. Downderry weather doesn't slow down for anyone.
