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.

How often should a roof be cleaned?

Every two to four years is a reasonable guide for most roofs, though shaded, tree-lined or coastal properties may need it more often. We can give a more specific recommendation once we've seen the roof.

How long does a roof clean take?

A standard softwash clean on an average semi usually takes half a day. Heavier moss scraping or larger roofs can take a full day or more — we'll give you a realistic estimate at survey stage.

What if my roof might contain asbestos?

We're asbestos awareness trained, so we know how to identify older roofing materials that may be a concern and handle the job appropriately rather than cleaning straight over it. Flag the roof's age when booking if you're not sure.

Are you insured for roof work?

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

Can I see before-and-after photos of my roof?

Yes — we use a pole-mounted camera to document gutters and roof condition, so you get genuine before-and-after evidence rather than just a description of the work.

Darlington sits around 17.6 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.

Everything is done from ground level or from access equipment — cherry picker or podium depending on the property — because walking a roof to clean it just isn't necessary with the right kit, and it's the single biggest cause of cracked and slipped tiles we get called out to fix elsewhere.

Safety and access come before the clean itself

Every roof job starts with how we're going to reach the roof safely, not with the cleaning method. Wherever possible we work from ground level with extension poles, or from a cherry picker or podium for higher and steeper roofs, rather than walking the tiles — that's both a safety decision and the single best way to avoid cracking or slipping anything up there.

We're fully insured, biocide trained, and follow proper spill management practice so nothing runs off into guttering, drains or planting where it shouldn't. Where a roof has visible asbestos-containing material, our asbestos awareness training means we know to treat it differently and flag it rather than clean straight over it.

Steam-clean approach

1
Survey and method check
We confirm steam is suitable for the roof type and staining before starting — it's not the right choice for every job.
2
Steam application
High-temperature steam lifts moss residue, algae and ingrained staining without pressure-washing or biocide chemicals.
3
Rinse and inspect
The roof is rinsed at low pressure and checked over for any missed patches, particularly in valleys and under overhangs.
4
Aftercare notes
We'll let you know if a follow-up biocide treatment would extend the result, since steam alone doesn't leave residual protection.

Homes & businesses

For retail and hospitality premises

A moss-streaked roof over a shopfront or pub isn't the impression most businesses want to give passing customers. We can schedule these jobs early morning or outside peak trading hours where that matters, and keep the site tidy while work's underway.

Commercial and mixed-use roofs

Units around North Road Industrial Estate and similar commercial premises often carry flatter roof pitches, larger surface areas, and sometimes a mix of tile, felt and flat-roof sections that each need a slightly different approach. Moss and algae buildup on commercial roofs tends to get noticed later than on a house, simply because fewer people are looking up at it day to day.

For commercial roofs we plan around business hours and access to loading areas or car parks, and can work to a maintenance schedule rather than a one-off clean where that suits the site better.
