Will cleaning damage my roof tiles?

Not when the method suits the roof. The covering, pitch and condition are checked first, and tiled roofs are not pressure blasted. If a roof is too fragile to clean, you will be told before work starts.

How long does a roof clean take?

It depends on the size, the amount of growth and the access. Ashford jobs are booked as full days on site, so the roof, gutters and any treatment can be finished in the visit.

Do you clear the moss out of the gutters afterwards?

Yes. Gutters and downpipes are given attention at the end, because loosened moss and debris need clearing rather than leaving to block the drainage.

Does moss come back, and what does biocide do?

Moss can return over time because spores arrive on the wind. A biocide applied after the clean kills remaining spores, so regrowth starts from a treated roof and is slower.

Is a roof in an Ashford conservation area cleaned differently?

Older clay tile and slate in areas such as Queens Road or Willesborough Lees are assessed carefully and given a lighter method. Nothing is altered, and if a gentler treatment is wiser you will be told before work starts.

Do you clean commercial roofs in Ashford too?

Yes. Commercial roofs are quoted with access arrangements agreed in advance, and coated metal roofs usually suit a low pressure soft wash.

Roof cleaning in Ashford, booked as full days

Moss, lichen and black streaks

Ashford's roofs fall into three broad eras. The oldest are in its eight conservation areas: Ashford Town Centre, Queens Road, Lacton Green, Willesborough Lees, Kennington and Ball Lane, Great Chart, Kingsnorth and Hothfield, where older clay tile and slate need a light hand. Then come the roofs of the 1959 London overspill, around 5,000 homes that created most of South Ashford and Kennington, many with concrete tiles now several decades old whose rough face moss and lichen grip easily. Newest are Park Farm from the late 1990s, Repton on the former Templer Barracks in the 2000s and Finberry from 2013, where roofs look smart for years and then pick up dark algae streaks down the slope.

Across Ashford borough, about a third of homes are detached, so many roofs are individual rather than shared terrace runs, and each is assessed on its own covering. Shaded slopes near the Great Stour and the Green Corridor stay damp for longer, which is exactly what growth needs.

Thick moss holds water against the tiles and sheds into the gutters. Lichen is flatter and tougher, and comes back if it is only scraped.

Our method

Roof moss removal is never treated as a standard pressure-washing job. Jordan checks the covering, pitch, condition, valleys, roof lights and safe access first, then explains the approach before anything is agreed. On tiled roofs, loose growth is removed with care rather than blasted off. Coated metal sheeting on commercial units usually suits a low pressure soft wash instead.

If a roof should not be cleaned, or would be better left with a gentler treatment, you will be told that before work starts.

Biocide treatment afterwards

Removing moss deals with what you can see, but spores stay in the tile texture and joints. A biocide treatment applied after the clean kills that remaining growth so the roof stays clearer for longer. It is offered as a separate line on the quotation, so you can decide whether to include it.

Biocide treatment

Gutters cleared at the end

Loosened moss and debris end up in the gutters, so they are cleared at the end of the job and the downpipes given attention. Leaving them would undo the point of cleaning the roof.

A few photographs taken from the garden or the road, showing each slope, are usually enough to start. Add your postcode and any access notes and Jordan will reply with a recommended method and a free written quotation.

Photograph the pattern, not just the darkest tile

An Ashford roof enquiry is easier to assess when the pictures explain how growth is distributed. Show a complete slope and then, from a safe position below, the area where moss gathers. Include an extension or adjoining roof if it obscures the eaves. A patch beneath a tree may need different consideration from streaking spread across an exposed face; neither photograph alone proves the tiles require physical cleaning.

If the property has newer roof sections beside an older covering, identify them in your message. Matching colours do not necessarily mean matching materials. Note where fallen moss collects and whether gutters overflow when it rains, rather than guessing at concealed damage. Because visits towards Ashford are planned as full days, a clear description of the whole roof helps establish the scope before the journey is arranged.
