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.

Do you walk on the roof to clean it?

No, not where it can be avoided. We work from ground level with extension poles or from access equipment like a cherry picker or podium, since walking tiles is one of the main causes of cracked or slipped roof coverings.

Can pressure washing damage a roof?

Yes, high-pressure jetting close to the surface can force water under laps and strip the protective weathering off tiles and slates. That's why we use softwash and low-pressure methods rather than a straight pressure wash.

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.

Are you insured for roof work?

Yes, we're fully insured for the roof cleaning work we carry out, including work from access equipment.

Do you guarantee the work?

We stand behind the quality of our cleaning and treatment. Regrowth timing varies by roof and location, so while we can't promise a moss-free roof forever, we'll always talk you through what to expect for your specific roof.

Does a mossy roof actually need cleaning, or is it just cosmetic? It's a fair question, and the honest answer is: it depends how far it's gone. A light dusting of algae is mostly appearance. Thick moss cushions holding water against tiles for weeks on end is a different problem entirely.

A softwashed roof looks like it's been re-tiled — moss gone, algae staining lifted, and none of the surface damage a pressure washer leaves behind. That's the result we're aiming for on every job, whether it's a single slope over a porch or a full three-bed semi in Sacriston.

Sacriston sits around 10.8 miles from the coast, close enough that salt-laden air and prevailing wind both play a part in how quickly roofs pick up algae and moss compared with drier inland spots. Add in the North East's fair share of damp, overcast weather and you've got conditions moss genuinely likes.

Low-pressure clean with gutter check

1
Combined-visit survey
We look at both the roof and the guttering together, since one visit covering both is usually more cost-effective than two.
2
Low-pressure wash
Loose debris and light moss or algae are washed off at low pressure, gentle enough not to disturb tile fixings.
3
Targeted biocide
Biocide is applied to areas with active moss or algae growth rather than blanket-treating a roof that doesn't need it.
4
Gutter clearance
Gutters are cleared and checked for flow, often using our pole-mounted camera to confirm they're running clean.
5
Photo record
Before-and-after photos are provided so you can see the difference without needing to get up a ladder yourself.

Steam cleaning equipment

Where a chemical-free approach suits the job better, we bring a steam unit capable of lifting algae staining and moss residue using heat alone. It's a good option for smaller roof areas or where biocide isn't preferred near ponds, planting or a vegetable patch below.

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.

What affects the price — method by method

Softwash-only jobs on roofs with light algae staining and no significant moss are usually the most cost-effective, since there's no scraping time involved. Heavy moss scraping adds time and cost roughly in proportion to how much has to come off before biocide can reach the tile surface underneath.

Softwash only (light staining)	from around £250
Softwash plus moss scrape	typically £400–£650
Steam clean (smaller areas)	typically £200–£400

Coastal and near-coastal exposure

Roofs closer to the coast around Sacriston tend to pick up algae staining faster than inland properties, thanks to a combination of salt-laden air, higher humidity and more exposure to driving rain. It's less about moss specifically and more a general acceleration of anything that likes damp — algae, lichen, general black staining on north-facing slopes.

We treat these roofs the same way structurally, but tend to recommend a shorter interval between cleans for anything close to the coast, since regrowth is generally quicker there than a few miles further inland.

Homeowners

Getting a roof ready before a sale

A moss-covered roof is one of the first things a buyer or their surveyor notices, and it can raise questions about condition that a clean roof simply doesn't invite. If you're preparing to put a property in Sacriston on the market, a softwash and moss scrape ahead of viewings is a relatively small cost against what a tired-looking roof can do to first impressions.
