Clean clay tiled roof after soft washing. A Star Decorators

RESIDENTIAL ROOF SOFT WASHING

Soft washing that lifts moss and algae off your roof without smashing the tiles

Low pressure treatment that kills the growth at the root and rinses it clean. The same trained crews and the same safety paperwork we run on national retail sites, on your house. Covering London and the South of England.

01 / service

When soft washing is the right call

  • The roof has green, black or red staining.
  • Previous jet washing cracked or lifted tiles.
  • You want it gone for 2-3 years, not back in a month.
  • Gutters and valleys are filling with washed down moss.

02 / why soft washing

Why pressure washing a roof is a false economy

High pressure water strips the protective surface off tiles, forces water under the laps, and spreads moss spores so it grows back faster. Soft washing treats the cause.

01

Cracked and dislodged tiles

Force lifts the edge of tired tiles and creates repairs you did not have before the clean.

02

Water ingress under tiles

Pressure drives water under laps and into places rain would not normally reach.

03

Faster regrowth

Spores are spread across the roof instead of killed at the root.

04

Voided tile guarantees

Some tile makers exclude damage caused by high pressure washing. We avoid that route.

03 / process

Survey first. Then the roof is treated properly.

01

Survey and access plan

Check the roof, gutters, safe access and the areas below before the method is agreed.

02

Protect and prep

Sheet planting, isolate gutters where needed and set the exclusion zone before treatment starts.

03

Soft wash and biocide treatment

Apply the treatment at low pressure so the product does the work, not force.

04

Rinse and clear down

Rinse, clear debris, check the gutters and leave the site tidy.

Working over your roof is no different to working over a live shop floor for us. Trained operators, planned access, signed RAMS, and a clean exit.

Frequently asked

Answers before the survey, not after the quote.

Will the chemical harm my plants or pets?
We sheet down planting and rinse the run off areas. The biocide breaks down once applied. We tell you what to move and when the garden is safe to use again.
Will you damage the tiles?
No high pressure touches your roof. Soft washing runs at garden hose pressure. The product does the work, not force.
How do you reach it safely?
Access is planned before we arrive: powered platform, tower or roof ladders as the survey decides. RAMS signed off before a boot goes on site.
How long does it last?
The biocide keeps killing regrowth after we leave, so a soft wash typically holds for 2 to 3 years before it needs another look.

“Had a good experience on a large scale retail superstore with interior and exterior decorations. Undercroft carpark spraying and fire intumescent coatings. Good attention to detail with a compassionate and professional lead from the director of the company.”
