How much does exterior cleaning cost in Harrow?

Most homes in Harrow should have gutters cleaned at least twice a year, ideally in autumn after leaves fall and in spring. Properties near trees may need quarterly cleaning. Signs you need gutter cleaning include water overflowing during rain, sagging gutters, plants growing from gutters, or damp patches on external walls. Regular cleaning prevents expensive water damage to your property.

Is pressure washing safe for my driveway or patio?

Yes, when done professionally. We adjust water pressure based on your surface type. Block paving, concrete, tarmac, and natural stone all require different pressure settings. Our experienced team knows exactly how to clean each material effectively without causing damage. DIY pressure washing often causes problems because people use too much pressure. We get it right first time.

What equipment do you use for window cleaning?

We use a pure water fed pole system for most window cleaning jobs. This produces streak-free, spotless results without chemicals. The purified water dries naturally without leaving marks. For interior windows or specific requests, we also use traditional methods with professional-grade squeegees and cleaning solutions. Our equipment reaches up to four storeys high safely from the ground.

Can you clean my gutters if they're very blocked?

Absolutely. Heavily blocked gutters are our specialty. We use industrial vacuum equipment that handles even the worst blockages, including compacted leaves, moss, and debris. We'll also clear downpipes and check the entire gutter system is flowing properly. If we find any damage or issues during cleaning, we'll let you know immediately so you can arrange repairs.

What's the difference between pressure washing and soft washing?

Pressure washing uses high-pressure water to blast away dirt, perfect for hard surfaces like driveways and patios. Soft washing uses lower pressure with specialised cleaning solutions, ideal for delicate surfaces like roofs, render, and painted surfaces. We choose the right method for your specific surface to get excellent results without damage. Sometimes we use both techniques on different areas of the same property.

Do you offer regular maintenance contracts?

Yes. Many of our five star customers book regular window cleaning every 4 to 8 weeks, gutter cleaning twice yearly, or annual pressure washing. Regular maintenance keeps your property looking great and prevents minor issues becoming expensive problems. We offer flexible scheduling and discounted rates for recurring customers. Our Google reviews frequently mention customers who've used us for years. Just ask about setting up a maintenance plan that suits your property and budget.

Will cleaning damage my roof tiles?

No. Before we start, we always carry out a full inspection of your property to assess the condition of your roof. We then use a high-flow, low-pressure cleaning method to safely remove most moss, algae, and debris without damaging your tiles. Any stubborn, hardened lichens are treated with our BAC 50 chemical biocide, ensuring your roof is cleaned thoroughly while staying protected.

How long does the treatment last?

After a professional roof clean, most moss, algae, and lichen growth will be removed, and a biocide treatment like BAC 50 helps prevent regrowth for around 2 to 3 years. We offer a 12-month guarantee on treated areas. If moss does return, we can come back and apply a chemical treatment at a reduced cost rather than carrying out a full roof clean. How long the effects last can vary depending on your roof's exposure, shade, and surrounding trees, but regular maintenance can help extend the treatment's lifespan.

Is roof cleaning actually necessary or just cosmetic?

Roof cleaning isn't just about appearances — while a clean roof looks better, it's also vital for the health and longevity of your property. Moss, algae, and lichen trap moisture, which can accelerate tile damage, cause leaks, block gutters, and affect the roof structure. As a leading exterior cleaning company, we recommend regular roof cleaning as preventative maintenance to help extend your roof's lifespan and avoid costly repairs.

How long does the job take and will it disrupt my day?

Most roof cleaning jobs take 1 to 2 days, depending on the size and complexity of your property. We work efficiently to minimise disruption, keeping your home safe and tidy throughout. You'll be kept posted throughout the process with regular updates and before-and-after photos of your roof, gutters, windows, or any other areas being cleaned, so you can see the progress every step of the way.

What about my garden, driveway, and windows?

We take care to protect your garden, driveway, and surrounding areas during any roof clean. Any dirt or debris created is thoroughly rinsed away. We'll initially rinse your windows to remove dust and debris, and at the end of the job provide a professional window clean with purified water to leave them streak free. We also rinse your patio, driveway, and garden to leave everything tidy. If you'd like, we can often quote and pressure wash your driveway and patio on the same day, giving your whole property a fresh, clean look at once.

Can I just clean it myself to save money?

You cannot, and we do not recommend it. For many exterior cleaning tasks like windows, driveways, or patios, a DIY approach can work. Roof cleaning is extremely dangerous — working on ladders with a pressure washing lance puts you at serious risk. DIY attempts often crack tiles, especially ridge tiles, force water under flashing, and miss moss roots so moss grows back quickly. Roof work is the second highest cause of DIY accidents in the UK, and your insurance likely does not cover it. Considering the average UK home is worth £300,000, paying trained, insured professionals ensures the job is done safely and properly, protecting both your home and yourself.

Yes. We are fully insured and professionally trained to carry out all exterior cleaning work safely. Our coverage includes indemnity insurance and public liability, meaning your property is protected while we work. Unlike DIY cleaning, any accidents or damage during the job are covered by our insurance, giving you peace of mind throughout the process.

The Real Cost of Moss on Your Roof

Property Value Loss

Moss-covered roofs reduce kerb appeal and property value. When potential buyers see a neglected roof, they assume structural problems and negotiate thousands off the asking price. Many of our Harrow customers book roof cleaning specifically before selling.

Tile Damage and Roof Failure

Moss roots penetrate tile surfaces, causing cracks and breaks. As moss expands, it lifts tiles and allows water ingress. The freeze-thaw cycle then accelerates damage. We regularly see roofs where moss has caused £5,000 to £15,000 worth of tile damage that could have been prevented with regular cleaning.

Water Damage and Damp

Moss holds moisture against your roof structure, increasing the risk of leaks, damp, and rot in roof timbers. Blocked gutters from falling moss debris compound the problem. Our customers often discover we've prevented serious water damage by cleaning their roof before problems develop.

Heat Loss and Energy Costs

Moss and algae reduce your roof's ability to reflect heat, increasing cooling costs in summer and trapping moisture that reduces insulation effectiveness in winter.

Why Choose Elite Spotless Solutions for Roof Cleaning?

Hire shop pressure washers often run at one fixed pressure. Too high for some surfaces (damages mortar, splinters wood, etches stone), too low for others (doesn't clean properly). We adjust pressure for each material. Block paving needs different pressure than natural stone or tarmac.

Frequently Asked Question

How much does roof cleaning cost in Harrow?

Roof cleaning typically costs between £300 and £800 for a standard residential property in Harrow. Price depends on roof size, pitch, access, and the level of moss coverage. A small bungalow might cost £300, while a large detached house could be £700+. We provide free surveys and fixed-price quotes before starting any work. Our customers regularly comment that our pricing is fair and transparent compared to competitors.

Will roof cleaning damage my tiles?

No, not when done properly with soft washing. We never use high-pressure washing on roof tiles, which can crack them, force water underneath, and cause expensive damage. Our soft washing method uses low pressure with specialist biocide treatments that kill moss and algae safely. We’ve cleaned over 400 roofs across Harrow without damaging a single tile. Cowboys who pressure wash roofs cause thousands in damage. We don’t.

How long does roof cleaning take?

A typical residential roof cleaning takes 4 to 8 hours depending on roof size, pitch, and moss coverage. Most jobs are completed in a single day. Complex or heavily moss-covered roofs might take longer. We’ll give you an accurate timeframe when we quote. We work efficiently without rushing, ensuring thorough cleaning and safe working practices throughout.

How often should I have my roof cleaned?

Most roofs in Harrow need cleaning every 3 to 5 years. Properties with overhanging trees or north-facing roofs may need more frequent cleaning due to increased moss growth. If you can see green moss from the ground, it’s time to clean. Regular cleaning prevents tile damage and extends roof lifespan, making it far more cost-effective than ignoring the problem until tiles need replacing.

What's the difference between soft washing and pressure washing?

Soft washing uses low pressure (similar to a garden hose) combined with specialist biocide solutions that kill moss, algae, and lichen at the root. It’s safe for tiles and highly effective. Pressure washing uses high-pressure water that can crack tiles, strip protective coatings, force water under tiles, and cause leaks. Professional roof cleaners use soft washing. Cowboys use pressure washers. We’re professionals.

Will the moss come back after cleaning?

Moss will eventually return over 3 to 5 years, but proper soft washing significantly extends the time between cleanings. We can apply protective coatings that further inhibit regrowth. The alternative is leaving moss to damage your tiles permanently, which costs far more than periodic cleaning. Many of our customers book maintenance cleaning every few years to keep their roofs in top condition.

Can you clean my roof if it's very steep or high?

Yes. We use mobile scaffold towers and specialist equipment designed for steep roofs and difficult access. Safety is paramount. We never compromise on safe working practices. If your roof requires special access equipment, we’ll factor this into the quote. Over 400 completed jobs means we’ve handled every roof type across Harrow.

Do I need to be home during roof cleaning?

Not necessarily. As long as we have access to an outdoor tap and can work around your property, you don’t need to be present. We’ll take before and after photos and send them with your invoice. Many customers leave us to work while they’re out. Our reviews often mention how much they trust us with property access.

What happens to all the moss and debris?

We remove all moss, debris, and organic matter from your roof and gutters. Everything is bagged and removed from your property. We also clear gutters of any moss that’s fallen during the cleaning process and ensure downpipes are flowing properly. Your property is left completely clean and tidy.

Is roof cleaning worth the cost?

Absolutely. Roof cleaning costs £300 to £800. Roof tile replacement costs £5,000 to £15,000+. Moss damages tiles, reduces property value, and causes water ingress. Our customers regularly tell us we’ve saved them thousands by catching problems early. It’s preventative maintenance that protects one of your property’s most expensive components. Far cheaper than the alternative.
