Roof Cleaning in Exeter
An Exeter roof soaks up plenty of soft, wet Devon weather, and the toll shows early. Moss sinks into the slate, dark lines bleed from the ridge, and growth collects in the gutters through the long wet spells that hang over the Exe valley. That build-up tends to have a season or two to spread quietly before anyone notices from the street. Unchecked, it locks moisture onto the slate, edges into the seams that keep a period roof sealed, and eases the old fixings loose over time.
The red-sandstone cathedral city on the Exe enjoys a mild, wet climate that suits moss all too well. The terraces of St Leonard's, Heavitree, St Thomas and Pennsylvania carry natural slate on steep pitches, Georgian stock stands near the cathedral close, and cob-and-thatch cottages sit in the villages beyond. River air off the Exe, the shade of the city's old trees, and the sheltered, humid valley leave these slopes slow to dry from one downpour to the next, the two rivers keeping the low city air soft the year through. The wooded hillsides above the city hold that damp in place.
We work these Devon roofs without ever standing on them, which keeps fragile slate and old detail whole. Easing moss, algae and lichen off each pitch and out of the valleys with specialist equipment, all worked off towers or the ground, we let nothing take our weight. For over 15 years Ben's Roof Cleaning has delivered experienced roof cleaning in Exeter this way, patch-testing before we start and closing with a non-toxic biocide against the regrowth the valley damp keeps feeding.
About Exeter
Exeter stands on the River Exe in Devon, a cathedral city with Roman walls, a medieval cathedral and a long history as the county's capital. Built largely of the local red sandstone, its old core sits above the river, with the restored quayside below and Victorian and later suburbs spreading out around it.
Housing runs to Victorian and Edwardian terraces and villas under natural slate, steep-pitched in the manner of their day, with Georgian stock by the cathedral close and newer building beyond. Old trees, the parks along the Exe and the wooded hillsides shadow whole roofs much of the day, and the valley pins the river damp to the slopes, just the setting moss favours.
Steep period slate, damp valley air and the mild, wet Devon climate give moss and algae the moisture they thrive on, so roofs weather and green faster here than across the drier counties. Along the shaded valley streets the change is plainest of all.
How Moss Takes Hold on Exeter Rooflines
Moss takes to an Exeter roof wherever the wet hangs about. The sheltered Exe valley keeps moisture in through the mild, wet Devon seasons, and slopes on the shaded side of a street catch little of the sun or wind that would dry them. That standing damp is all a colony of moss needs to grip the slate.
Old slate gives the growth its grip. Weathered natural slate wears a textured face that spores hold to easily, and the steep period pitches trap leaf debris where it collects in the valleys. Once moss mats along a course, it pins yet more water onto the slate below and spreads.
Aspect decides where the damage bites. North-facing pitches and the lowest courses by the gutter keep the least sun and the most damp, so growth is always worst there to begin with. Clearing it soon keeps the harm on the slate face rather than in the laths and fixings below.

The Right Way to Clean an Exeter Roof
Cleaning an older Devon roof well begins by reading it, not blasting it. The age of the slate, the steep pitch and the depth of growth all set how an Exeter roof gets tackled, and so a patch test and a close look lead the work. That care protects slate that has stood generations of valley weather.
On old slate, method matters more than force. Growth is eased off the pitches and out of the valleys with specialist equipment rather than scraped or stood on, so brittle slate keeps its face and nothing splits underfoot. The valley gutters, downpipes and hopper heads are cleared the same visit, where the debris collects.
A careful finish is what makes it hold. With the roof clear, a non-toxic biocide is worked over the slopes and into the shaded valleys to slow moss returning in the damp valley air. A closing check then passes over the tiles, flashing and roofline before the site is left tidy. Old valley slate rewards that patience well.
How Ben's Roof Cleaning Works on Exeter Roofs
Getting an older city roof right turns on method, and ours starts by understanding it. We survey the slopes, read the slate and the growth, and talk through what we find, which is why homeowners have chosen Ben's Roof Cleaning for dependable roof cleaning in Exeter over more than 15 years across the city.
From there the no-contact method takes over. Reaching up from towers or ground level, we ease the growth away without loading a slate or disturbing old detail, protect the garden below, and clear all the debris we bring down. Fully insured, we handle villa and terrace alike with care.
What protects the work is the finish. Once the slope is clear a non-toxic biocide goes on to slow moss returning in the shaded corners, and a last check passes over the slates, valleys and ridge line before we leave the site clean. In the damp valley air a treated slope holds far longer than a bare one.

Frequently Asked Questions
Does the damp Devon weather make roofs worse in Exeter?
Very much so. The sheltered Exe valley and the mild, wet Devon climate keep even steep slate moist, so moss takes hold fast. Shaded slopes near the river and under the trees colour over well before the open, sunnier ones do.
Can you clean an old period or cottage roof safely?
Yes, with real care. The aged slate on the city's period houses never sees a boot with us. We patch-test at the start, then work the growth off the pitches and out of the valleys from towers or below.
Will the clean damage my old slate?
No. Nobody treads the roof, and the growth is coaxed free with specialist equipment, so the slate meets no scrape or load. That protects fragile Devon slate, which chips readily beneath a foot on a steep pitch.
Do you clear the valleys and hopper heads?
Yes. The valley gutters, downpipes and hopper heads all come clear with the roof, since debris off the steep pitches lodges there. Keeping them open stops water pooling under the trees along the valley floor after rain.
Why does moss keep regrowing on valley slate?
Damp and shade keep spores living in the old slate, so a plain clean greens over again before long. The non-toxic biocide we close with keeps at it for months, slowing the return through the city's wet valley air.
How do I know an old roof needs cleaning?
Moss set into the slate, dark streaks off the ridge, and growth in the shaded valleys and gutters all mark trapped wet. Message us and we will study it from the pavement and say where it stands.
Are you covered by insurance for the job?
Yes, insured on every job. The access is looked over and the towers set properly before any work starts, keeping your Exeter home and the team safe from the first ladder-rung right to the last.
What happens during a complete clean?
We survey the roof, clean it softly, clear the valleys and gutters, rinse the ground, and walk you round the finished pitch with pointers, all left tidy before we go. The old slate is handed back sound.
