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.

Will the moss just come back?

Some regrowth over time is normal — biocide treatment slows it considerably compared with an untreated roof, but nothing stops moss returning eventually given the right conditions. Regular maintenance cleans keep it from building back up to the level it was at before.

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.

Are you insured for roof work?

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

How do I get a quote?

Call Trevor on 07501 060609 or get in touch through the website. We'll usually want to see the roof, either in person or from photos, before giving a firm price.

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.

A roof that's gone green rarely gets noticed until it's bad. Moss builds slowly along ridge lines and in the shaded valleys of a roof, lifting tiles as it thickens and holding water against the felt underneath for months at a time. By the time it's visible from the street in Willington, it's usually been growing for a couple of seasons already.

Roof cleaning in Willington typically runs from around £250 for a small softwash job up to £600 or more for a larger roof with heavy moss needing a full scrape and biocide treatment. Exact cost depends on roof size, pitch, access and how much moss has to come off before treatment.

Willington sits around 16.5 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.

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.

Biocide treatment

The core product on most jobs is a professional-grade biocide designed to kill moss, lichen and algae at the root rather than just stripping visible growth off the surface. Applied evenly across the whole roof at low pressure, it keeps working after we've left, which is what slows regrowth compared with a rinse-only clean.

The products and equipment behind the clean

The core of the job is a professional-grade biocide, applied by low-pressure sprayer, formulated to kill moss, lichen and algae at the root rather than simply stripping the visible growth. It's applied evenly across the whole roof surface so nothing gets missed in shaded corners or valleys, which is usually where regrowth starts first if a job's been rushed.

Alongside the biocide we carry hand tools for moss scraping, a steam unit for jobs where chemical-free cleaning is preferred, and access equipment — extension poles, cherry picker or podium — chosen to reach the roof without anyone needing to stand on it. Which combination we bring depends on the survey, not a fixed package.

Coastal and near-coastal exposure

Roofs closer to the coast around Willington 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

For residents who'd rather not deal with it themselves

Roof cleaning isn't a job we'd recommend most people take on themselves — it's not really about ability, it's about the equipment and the risk of a fall. We handle the whole thing from survey to clean to gutter check, so there's nothing for you to arrange beyond letting us know a roof needs attention.

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

Roof Cleaning & Moss Removal in Willington — common questions

Softwash, steam or low-pressure — whichever suits your roof type, moss coverage and access best. We assess before we clean rather than running the same process on every job in Willington.

A roof cleaned before moss gets thick costs less and takes less time than one left until it's a full scrape job. Whether you're in Willington or nearby, getting it looked at now is generally the cheaper option.

Green roof, blocked gutters, or moss that's been building up for years — we clean it properly, treat it so it stays cleaner for longer, and never walk your tiles to do it.
