Does my roof actually need cleaning?

If there's visible moss, especially thick cushions in valleys or along ridge lines, or dark algae staining across a north-facing slope, it's worth having cleaned. A light green tinge with no thick growth can often wait, but it's worth a look before it gets worse.

How much does roof cleaning cost?

Typically from around £250 for a smaller roof with light staining up to £600 or more for a larger roof needing a full moss scrape and biocide treatment. We survey before quoting so the price reflects your actual roof.

Can I clean the roof myself?

It's possible for very minor work, but roof cleaning carries real fall risk and the wrong products or pressure can damage tiles. Given the height and access involved, most people are better off having it done professionally.

What weather do you need for roof cleaning?

Dry, calm conditions are best, particularly for access equipment work, which we avoid in high winds for safety reasons. Light rain doesn't always stop a job but heavy or persistent rain usually means rescheduling.

Do you clear gutters as part of a roof clean?

We can, and it's often sensible to do both on the same visit since moss and grit dislodged during roof cleaning tends to end up in the gutters anyway. Ask us to quote both together when you book.

Can moss actually damage roof tiles?

Yes — moss holds moisture against the tile surface for long periods, which over time can contribute to frost damage, lifted tiles and blocked gutters as growth washes off during rain. It's a slow process but a real one.

Stockton-on-Tees Borough Council · TS15 · 28.1 miles south of our Washington base

We clean roofs across TS15 and the surrounding postcodes using softwash, steam or low-pressure methods depending on the roof, always working from ground level or access equipment rather than walking the tiles. It's a slower way of working, but it's the one that doesn't crack a slate to save ten minutes.

There's a common idea that the only way to clean a roof properly is to get up there with a pressure washer and blast it. In practice that's usually the worst thing you can do — high-pressure water forces its way under tiles and slates, strips the protective weathering off the surface, and can turn a cosmetic moss problem into a leak within a season or two.

We clean roofs across Yarm and the wider North Yorkshire area using softwash, steam and low-pressure methods — moss scraped off by hand where needed, biocide applied to kill what's left at the root, all done from ground level or access equipment rather than walking the tiles.

Pole-mounted camera

We use a pole-mounted camera to check gutter condition and confirm the roof's been cleaned thoroughly, without anyone needing to climb up for a look. It also gives you genuine before-and-after evidence of the work rather than a description of it.

What we do — and what we deliberately don't

We do clean from ground level or from access equipment such as a cherry picker or podium steps. We do use low-pressure softwash and biocide rather than high-pressure jetting. We do hand-scrape heavy moss before treating, and we do check gutters while we're up there.

We don't walk on tiles unless there's genuinely no other way to reach a section, and even then only with roof ladders and boards to spread the weight. We don't pressure-wash roofs with a wand at close range — it's fast, but it's also how good roofs get turned into leaking ones. And we don't apply biocide to a roof that hasn't been scraped clear of heavy moss first, because it won't reach the surface underneath.

Roof Cleaning & Moss Removal near Yarm

Fitting access equipment to your street

Terraced streets, tight driveways and shared parking all affect what access equipment we can realistically use on the day, so we ask about parking and street width when booking rather than turning up and finding out. Most jobs work fine with a cherry picker or podium parked on-street; some need a bit more planning.

Roof cleaning cost by rough property size

As a general guide, cost tends to scale with roof area rather than house size on paper — a bungalow with a large roof footprint can cost more to clean than a narrow-fronted terrace with a tall roofline. Access matters too: a roof reachable from a driveway is usually cheaper to clean than one needing scaffolding-style access equipment on all sides.

Terraced house	typically £250–£400
Semi-detached	typically £350–£500
Detached	typically £450–£750
Bungalow (larger roof area)	typically £400–£650
Heavy moss/difficult access surcharge	typically +£50–£150

Homeowners

New to a property and inheriting a mossy roof

If you've recently taken on a house in Yarm and the roof clearly hasn't been touched in a good few years, that's a common and very fixable starting point. We'll survey the roof, tell you honestly whether it's a straightforward softwash or needs a fuller scrape first, and get it back to a condition you can maintain going forward.

Exposed roofs on higher ground

Properties on higher or more exposed ground catch more wind-driven rain and generally see more temperature swings than sheltered streets lower down, which can mean faster weathering on ridge tiles and pointing as well as more moss on north- and west-facing slopes that stay damp longest.

Access is usually the bigger practical issue on exposed sites — wind affects what access equipment we can safely use on a given day, so these jobs sometimes need a bit more flexibility on scheduling than a sheltered terrace would.
