Your roof is a working system that sheds water, protects structure, and keeps heat where it belongs. When moss, algae, and debris are left to build up, that system struggles. In our local climate – with shaded streets, mature trees, and changeable weather – roofs in and around Milton Keynes collect organic growth faster than many homeowners realise. Professional roof cleaning not only refreshes appearance, it also helps prevent leaks, reduces damp risk, and can extend the life of tiles, slates, and membranes.

Maxwells Roofing is a family-owned, owner-led team headed by Luke Maxwell. We use careful, proven methods that respect your roof type, follow UK safety regulations, and minimise disruption. Homeowners choose us for clear communication, tidy work, and results that last.

1. Why cleaning your roof matters

Moss, lichen, and algae hold moisture against roof surfaces. Over time, that moisture can freeze-thaw, expand, and damage tiles or slates. Debris travels into gutters and downpipes, leading to overflows, stained walls, and potential damp. Organic growth can also lift tiles slightly and compromise overlaps, increasing the chance of water tracking under the roof covering during wind-driven rain.

Benefits of professional roof cleaning include:

• Better water run-off and less standing moisture on tiles and slates.
• Lower chance of leaks by keeping overlaps and flashings clear.
• Fewer damp issues around walls and eaves thanks to clear gutters and downpipes.
• Longer covering lifespan by removing growth that accelerates surface wear.
• Cleaner skylights, valleys, and abutments for improved performance and appearance.
• Improved kerb appeal and buyer confidence when selling or refinancing.

2. DIY vs professional – risks you can avoid

Cleaning a roof looks simple from the ground, but using the wrong method can cause unintended damage or safety hazards. A professional approach protects both your property and the people working on it.

• High-pressure jetting risk – strong jets can strip tile coatings, damage slate, and drive water under laps. We avoid destructive pressure methods on vulnerable coverings.
• Water ingress – poor technique around overlaps, flashings, and vents can force water into the roof build-up. Our methods reduce ingress risk and respect the way each covering is designed to shed water.
• Working at height – falls remain one of the most common home-related accidents. We use the correct access equipment and trained operatives.
• Chemical misuse – the wrong products or overuse can harm landscaping and pollute drains. We follow product guidance and handle run-off responsibly.
• Hidden defects – cleaning often reveals cracked tiles, slipped units, or failing mortar. We can identify and fix minor issues before they escalate.

A careful, methodical clean is an investment in the health of your roof covering and the fabric of your home.

3. Safe cleaning methods we use

Every roof is different. Before any work begins, we carry out a visual survey, capture photos, assess access, and identify fragile areas and details that need special care. Then we select the most suitable approach for your roof type and condition.

• Manual moss removal – gentle scraping and brushing to lift moss without roughing tile or slate surfaces.
• Low-pressure steam cleaning – used where appropriate to lift staining and biofilm with minimal water volume and lower ingress risk.
• Targeted soft-wash treatment – professional-grade biocides applied to neutralise spores and slow regrowth, following manufacturer guidance.
• Gutter and downpipe clearing – we collect dislodged debris and ensure free-flowing drainage before we leave.
• Detailing and sensitive areas – careful work around chimneys, valleys, skylights, vents, solar fixings, and abutments to protect seals and overlaps.
• Aftercare plan – optional follow-up inspection and top-up treatment to keep your roof looking better for longer.

Where we find slipped or broken tiles, minor verge issues, or small flashing defects, we can often complete simple remedial work during the same visit, saving time and return trips.

5. Safety, regulations, and good practice

Roof cleaning usually does not require Building Control notification. Even so, our approach always respects UK regulations and widely accepted good practice:

• Working at Height Regulations – planned access, trained operatives, and safe systems of work.
• COSHH and environmental care – controlled use of treatments and responsible debris handling.
• Ventilation and moisture performance – keeping eaves and roof vents clear so the roof space can breathe.
• Fire and covering performance – suitable methods on flat roofs to avoid compromising surface classifications.
• Structure and weight – no unnecessary loading or actions that might weaken fixings or battens.

If we discover that a section of roof needs significant refurbishment or replacement, we will explain any steps that may require notification or additional upgrades such as insulation when large areas are renewed.

6. Roof types we clean

• Concrete and clay tiles – manual removal followed by low-pressure cleaning where appropriate, plus targeted treatment to slow regrowth.
• Natural slate – gentle, non-abrasive techniques that respect slate layers and traditional fixings.
• Flat roofs – EPDM, felt, and GRP surfaces cleaned with low-pressure methods that avoid forcing water at seams or edges.
• Skylights and roof windows – cleaning and sealing checks to improve light and water control.
• Solar PV arrays – careful cleaning around frames and fixings while maintaining watertightness and manufacturer guidance.

We plan access to minimise foot traffic on fragile coverings and use scaffold towers or MEWPs where needed for safe, efficient work.

7. When to clean – frequency and signs

In Milton Keynes and surrounding areas, a sensible routine is:

• Roof and gutter inspection every 12-24 months.
• Cleaning every 3-5 years, with optional top-up treatment in shaded or tree-lined streets.

Common signs to look out for:

• Green moss cushions or thick lichen patches on tiles or slates.
• Black or dark streaking on north-facing slopes.
• Overflowing gutters during rain or frequent downpipe blockages.
• Slipped or cracked tiles where trapped moisture has expanded.

Timing through the year:

• Spring to autumn often provides faster drying and good conditions for treatments.
• We work year-round and adjust methods to weather, always prioritising safe and reliable outcomes.

8. What to expect – process and typical timescales

Every roof is unique, so our quotes are tailored to your property, roof type, and access. You will receive a clear scope of work and a fixed price before we start.

1. Survey and photos – we assess access, identify fragile areas, and document the roof and gutters.
2. Preparation – protection for landscaping where needed, safe access installed, and gutters isolated for debris control.
3. Cleaning – manual removal, low-pressure steam where appropriate, and careful detailing around features.
4. Gutters cleared and flushed – dislodged debris removed and water flow restored.
5. Treatment – targeted soft-wash to neutralise spores and delay regrowth.
6. Final checks – photos, review of flashings, overlaps, and ventilation pathways, plus any recommendations.

Timescales: Most standard homes take 1-2 days, depending on size, pitch, access, and growth levels. Larger or complex properties may take longer. We will always explain the plan before work begins.

9. Keep it cleaner for longer

A simple maintenance plan keeps your roof performing and looking its best without over-cleaning:

• Inspection every 12-24 months to catch minor issues early.
• Gutter cleaning at least once a year, or more often under heavy tree cover.
• Top-up treatment in shaded areas to slow regrowth and extend time between full cleans.
• Proactive small repairs – replacing slipped tiles, resealing minor flashing issues, and keeping vents clear.

Ask about bundling inspections and gutter maintenance for convenience and savings.

10. Roof cleaning FAQs

Is pressure washing safe for roofs?

High-pressure jetting can remove protective tile finishes, damage slate, and drive water under laps. We use manual methods, low-pressure steam where appropriate, and targeted treatments to deliver clean results with minimal risk.

How long do results last?

That depends on shading, nearby trees, and local conditions. With treatment, most roofs stay clean for several years. Inspections every 12-24 months help keep things on track.

Do you clear gutters as part of the service?

Yes. We clear and flush gutters and downpipes so the whole system performs as intended.

Will cleaning void a roof warranty?

Our methods are designed to be compatible with common roof coverings. If you have a specific manufacturer warranty, tell us and we will follow the recommended maintenance guidance.

Can you work around solar panels and skylights?

Yes. We clean carefully around frames and fixings, protect seals, and maintain watertightness.

Do I need permission or approval to clean a roof?

Cleaning usually does not require Building Control. If larger repairs or refurbishment are needed, we will advise on next steps before any additional work is carried out.
