Roof Cleaning Market Harborough
Green moss, black algae and grey lichen creep across roofs all over the Welland Valley. On a north-facing slope they take hold fast, holding damp against the tiles and blocking gutters. Roof cleaning in Market Harborough is one of the most misunderstood jobs on a house. Done the wrong way, it does more harm than the moss ever would.
Tate & Sons Roofing cleans roofs the safe way. We use soft washing and careful hand work, never a high-pressure lance. This page explains why that matters, what each method costs, how often a roof needs cleaning, and what to watch for. Roof cleaning is one part of the wider service we offer as a roofing contractor across Market Harborough. Start with a free drone survey and a written quote before any work begins.

Is Roof Cleaning Actually Worth It?
A clean roof is not only about looks, though the kerb appeal is real. Thick moss holds water against your tiles long after the rain stops. That trapped damp works into tiny cracks, then freezes and expands in winter. Over a few seasons it lifts and splits tiles that were otherwise sound.
Moss also breaks off in clumps and slides into your gutters and valleys. Blocked gutters overflow down the wall, and blocked valleys back water up under the tiles. Both cause damp inside long before you spot the leak. A proper clean clears the growth, frees the drainage, and lets us check the roof over while we are up there.
So yes, cleaning is worth it when the growth is heavy or the gutters keep clogging. Homes near mature trees around Great Bowden and Lubenham see it worst. On a bright, exposed roof with only light staining, a clean is more about appearance than protection. We give you a straight answer either way.
The Warning Signs Your Roof Needs a Clean
You do not need to climb up to spot most of these. A look from the garden or the street tells you plenty.
Watch for these:
- Thick green moss cushions sitting proud of the tile surface
- Black or grey streaks running down the slope
- Clumps of moss collecting in the gutters or on the ground
- Gutters overflowing in heavy rain despite being clear of leaves
- Patchy white or pale-green lichen crusting the tiles
- A north-facing slope that stays damp and dark for days
- Debris packed into the valleys between two roof slopes
One or two of these does not mean a crisis. A roof carries a little growth for years without trouble. The point to act is when moss starts blocking drainage or falling in clumps. That is the stage where it stops being a cosmetic issue and starts letting water where it should not go.
Why We Never Pressure Wash Your Roof Tiles
A high-pressure jet wash looks impressive and clears moss in minutes. It is also the fastest way to wreck a roof. The trade and the tile makers agree on this, and so do we. We turn down more pressure-washing requests than we take.
Concrete and clay tiles carry a factory surface layer that sheds water and slows regrowth. A pressure lance strips that layer clean off. The tile is left rough and open-pored, so it soaks up water and moss comes back faster and thicker than before. You end up cleaning more often, not less.
High pressure also cracks older tiles outright and drives water up under them, straight onto the felt and timber below. The National Federation of Roofing Contractors warns against power-washing for exactly these reasons. You can read their plain advice on moss on your roof before you let anyone near your tiles with a jet wash. Many tile makers void the warranty if a roof has been pressure washed.
Soft Washing Cleans the Roof Without the Damage
Soft washing is the method that suits almost every tiled roof in Market Harborough. It uses very low pressure and a proper cleaning solution rather than brute force. The solution kills the moss, algae and lichen at the root, so the growth dies back and washes away gently.
Where the moss is thick, we scrape and brush the worst of it off by hand first. Careful hand work lifts the heavy growth without touching the tile surface underneath. Then the biocide treatment goes on to kill what is left and hold back regrowth. Results from a good soft wash and biocide typically last two to five years, depending on how shaded the roof sits.
Once the roof is clean and dry, some homeowners ask about protecting it further. Our Roof Coatings and Sealing service is a separate step for that. For the growth itself, our Moss & Algae Removal page goes into more detail on treatment and prevention.
Roof Cleaning Methods Compared
Three approaches cover most roof cleaning jobs. The right one depends on how heavy the growth is and what your tiles are made of. In short: soft washing suits most tiled roofs. Hand scraping clears heavy moss first. Low-pressure rinsing has its place on hard surfaces, but carries more risk. The table below sets out the trade-offs in plain terms.
| :-: | :-: | :-: | :-: |
| Method | Typical cost (per m²) | Risk to roof | Best for |
| Soft wash + biocide | £12–£16 | Low | Moss, algae and lichen on most tiled and slate roofs |
| Manual scrape & brush | £8–£15 | Low | Clearing heavy moss by hand before a soft wash |
| Low-pressure rinse | £8–£15 | Moderate | Hard, sound concrete tiles where care is taken |
- **Soft wash and biocide*is our default on tiled and slate roofs. Low pressure, a root-killing solution, and no harm to the tile surface. It gives the longest-lasting result.
- **Manual scrape and brush*is hand work for heavy moss. We lift the thick growth off first, then soft wash what remains. Slower, but it protects the tiles.
- **Low-pressure rinse*uses a gentle flow, well below a jet wash. It has a place on hard, sound surfaces, but we keep it well away from old or fragile tiles.
Ryan Tate, our project manager, is up on the roofs doing this work himself. He will look at your tiles and tell you which method suits them, in plain English rather than sales talk.
How Often Should You Clean Your Roof?
There is no single answer, because it depends on your roof. A shaded, north-facing slope under trees near Foxton or Medbourne grows moss far quicker than an open, sunny one. Roof pitch matters too, as steeper roofs shed growth better than shallow ones.
As a rough guide, most roofs benefit from a clean every few years once growth takes hold. A soft wash with biocide buys you two to five years before it needs doing again. Cleaning too often does more harm than good. We would rather you did it when the roof needs it, not on a fixed timetable.
The better habit is a yearly look and a gutter clear each autumn. Keep the drainage flowing and you slow the whole problem down. If you spot moss falling in clumps or gutters backing up, that is the signal to book a survey.
What Roof Cleaning Costs in Market Harborough
Cost comes down to three things: roof size, how heavy the growth is, and access.
As a general guide, a full soft wash runs roughly £12–£16 per square metre, with hand scraping and low-pressure work around £8–£15. For a typical semi-detached house, that lands somewhere around £350–£800 for the whole roof. A separate biocide treatment usually adds £150–£300 and is what makes the result last.
What pushes a price up or down:
These are general market ranges, not a quote for your roof. Two houses the same size can price very differently once growth and access are factored in. The only way to a firm figure is a proper look at your roof, which is exactly what our free drone survey gives you. A fixed price needs a survey.
- **Roof size and pitch*— a bigger or steeper roof takes longer and needs more care
- **How heavy the moss is*— thick growth means more hand scraping before the wash
- **Access*— if the job needs scaffold or a cherry picker, add roughly £150–£400
- **Gutter and valley clearing*— usually rolled into the job while we are up there
- **Biocide treatment*— the extra step that holds regrowth back for years
Why Market Harborough Homeowners Call Tate & Sons First
You are not just buying a wash — you are buying whoever does it, and whether they respect your tiles. Ryan Tate, our project manager, joined the trade full-time after his NVQ Level 3 in Roofing. He is on the roofs doing the cleaning himself, not just the man who quoted it. He knows which tiles a pressure lance would ruin, and he never uses one.
Founder Michael Tate started his apprenticeship at sixteen and built Tate & Sons on one conviction: look at the whole roof first, then do the job that actually protects it. He surveys every roof before we clean it. Between us we carry over 45 years of combined experience, hold NVQ Level 2 and 3 qualifications in Roofing Occupations, and keep CSCS cards and NFRC trade-body membership.

Got Questions?
Your Roof Cleaning Questions, Answered Properly
Does pressure washing damage roof tiles?
Yes, it often does. A high-pressure jet strips the protective surface off concrete and clay tiles, leaving them rough and open to soaking up water. It cracks older tiles and drives water up underneath onto the felt and timber. The roughened surface then grows moss back faster than before, so you clean more often. This is why we soft wash rather than pressure wash.
Is roof cleaning worth the money?
It is worth it when moss is heavy or your gutters keep blocking with growth. Thick moss holds damp against the tiles and clogs the drainage, which can let water inside over time. A clean clears that and lets us check the roof over. On a bright roof with only light staining, cleaning is more about appearance than protection, and we will tell you so.
What is soft washing?
Soft washing uses very low pressure and a proper cleaning solution instead of brute force. The solution kills the moss, algae and lichen at the root, so it dies back and rinses away gently. Where growth is thick, we scrape the worst off by hand first. It cleans the roof without stripping the tile surface, which is why it lasts longer.
How much does it cost to clean a roof in Market Harborough?
As a general guide, a soft wash runs around £12 to £16 per square metre, with a typical semi-detached roof landing somewhere between £350 and £800. A biocide treatment to hold back regrowth usually adds £150 to £300. Scaffold or a cherry picker, where needed, adds more. A free drone survey gives you an exact written price. A fixed price always needs a survey first.
How often should a roof be cleaned?
It depends on your roof, but most benefit from a clean every few years once growth takes hold. A soft wash with biocide typically holds for two to five years. Shaded, north-facing roofs under trees need it more often than open, sunny ones. Cleaning too often does more harm than good, so do it when the roof needs it, not on a fixed schedule.
Will roof cleaning damage my tiles?
Not the way we do it. Soft washing and careful hand work clean the growth without touching the tile surface underneath. The damage people worry about comes from high-pressure jet washing, which we do not use on tiles. We match the method to your tiles, and we keep even low-pressure rinsing well away from old or fragile ones.
Does moss really need removing from a roof?
Not always. A little moss on the tiles is rarely a problem on its own. It needs removing once it starts blocking gutters and valleys or falling in clumps that clog the drainage. That is the stage where trapped water can find its way inside. We look at the whole roof and tell you whether it genuinely needs doing.
Can you clean the gutters at the same time?
Yes, and we usually do. Moss and debris clear off the roof straight into the gutters, so clearing them is part of the same job. Free-flowing gutters and valleys are half the battle against roof damp. We leave the drainage running clean before we come down, and check it over while we are up there.
