Basic Roof Cleaning Services

Having your roof cleaned is a relatively new service offered to home-owners who have a problem with bacterial and fungal infestations on their roofs. The most common problems are green and black algae, mosses, mildews, and moulds as well as other fauna. These create a problem for shingles and tiles and also attract birds which may result in unwanted nests and clogged gutters. Roof cleaning services include removing the algae, clearing gutters and inspecting for damage. Then Dorset roof cleaners will then recommend repairs if required.

What Causes Those Black Streaks?

Black streaks on a roof are the most common cause for concern. These often harbour a number of fungal and bacterial growths including common green and black algae. Fungal infestations can be extremely damaging. The layer of spores increases the heat and humidity on your roof which can warp shingles and damage roof materials. Fungi also feed on tar and limestone disturbing the roofing compounds responsible for UV protection. This can greatly reduce the longevity of your roof.

The Pressure Washing System

Although pressure washing has been a preferred method of roof cleaning for several years, this process can be more detrimental in the long run. Pressure washing should only be used for rinsing an already cleaned roof, never for the removal of fungi and algae itself. The high pressure jet of water can erode your roof, damaging shingles and tiles, while only spreading spores of algae and mildews resulting in a thicker, healthier regrowth. Pressure washing merely prunes without addressing the root of the problem.

This involves:

Setting up access equipment
Inspecting the roof for signs of damage and replacing as required
Disconnecting guttering and covering yard areas with plastic sheeting
Cleaning guttering and reconnecting downpipes
Applying a coat of moss repellent once roofing has dried
Removing access equipment and waste products and cleaning windows if needed

Soft-wash Roof Cleaning

The better method of Dorset roof cleaning includes the use of low pressure water systems complete with sanitation chemicals to bleach and kill colonies of algae and fungi. The soft-wash method poses no risk of erosion and allows for a deeper permeation of chemicals so that the unwanted pests are not only removed once, but are also prevented from returning. Be sure to discuss different cleaning methods with the professionals as some roofing materials may not be able to withstand certain chemical washes.

This will involve:

Erecting an access tower to get on to the roof
Covering garden and paved areas
Removing moss by scraping it off the roof manually
Sweeping tiles to ensure smaller particles are removed as well
Inspecting the roof and performing any repairs that may be needed
Clearing guttering and downpipes
Applying a coat of moss treatment
Removing all waste and access equipment

Why it’s Essential to Remove Moss and Dirt from a Roof

Not only does an accumulation of moss make your roof look unsightly; over time, it can cause damage to some types of roofing as well. Clay and cement tiles can be especially prone to damage because the moss is able to eat into them over time.

When having your roof cleaned, it’s also recommended that a new coat of sealant be applied to it afterwards. This will help prevent leaks from forming over time.

How Long will the Moss Take to Reappear?

Homeowners who only opt for manual moss removal and not the required post treatment will see this pesky substance re-growing within a very short period of time. This happens because it’s impossible to remove every single moss spore from a roof.

Having the moss treatment performed will help ensure that any hidden moss spores are eliminated, which will in turn keep your roof clean for far longer. It’s usually recommended to have a moss treatment applied to your roof once every two to three years.

Factors that affect how quickly moss grows back on a roof include:

Climate
Whether any other roofing in the immediate area has a moss covering or not
Amount of trees and other tall structures surrounding your home – the more shade your roof is in, the quicker moss will grow back

Comparing Moss Removal to Pressure Cleaning

Many homeowners find themselves feeling unsure about whether they simply need to have the moss manually removed from their roofing or whether it will be better to simply pressure wash the entire roof. The only way to determine which of these methods will be most suitable is to have a professional roof cleaner assess your property.

In cases where roofing is in poor condition and issues such as missing pointing, torn membrane or underlay, loose flashing or broken tiles, it is not recommended to have it pressure cleaned because water will most likely penetrate into your home.

Manual moss removal is a far gentler option, making it more suitable for older roofing and/or that which is damaged. It’s also a less messy option than pressure cleaning in most cases.

Average Roof Cleaning Costs

Roof cleaning prices will vary according to the part of the country your property is in, its size and whether it needs to be cleaned manually or with a pressure washer. Below are examples of approximate pricing for these services:

Removing roof moss and applying a biocide treatment to prevent re-growth can average between £5 and £15 per m²
Having your home’s roof pressure washed can cost anywhere between £7 and £20 per m²

Basic examples of pricing for different types and sizes of properties:

A small terraced or semi detached home could cost between £350 and £420 to clean
Slightly larger terraced or detached homes could attract roof cleaning rates of between £480 and £520
A bigger single family home’s roof cleaning cost can vary between £550 and £650
Larger than average double storey homes could attract roof cleaning costs of between £750 and £850 – or more if the roof area is excessively large

Factors Affecting Roof Cleaning Costs

Several factors will have an effect on the cost of quotes you receive to have your home’s roof cleaned:

Size of the company performing the task - larger companies will have more employees and higher overhead costs than smaller businesses – and these costs will ultimately be passed on to clients
Size of the roof - a roof on a smaller home will generally cost less to clean than one on a larger property
Ease of access - do any parts of your roof require scaffolding access, or will any public areas such as walkways need to be used to access your home’s roof? If so, this will result in you obtaining higher priced quotes
Amount of dirt and moss that has accumulated on the roof - the grimier it is, the more time and effort will be needed to clean it properly
Type of roof - some types of roofing require specialised forms of cleaning, which can be more expensive
Method used to clean the roof - is power washing required or will the build-up need to be scraped off manually?
Are that your home is situated in - quotes tend to be higher in central London than in the north, south and Midlands

How Long Does Roof Cleaning Take?

The amount of time needed to perform roof cleaning depends on a few factors:

Amount of moss, algae and dirt that is on the roof
Size of the roof
Ease of access to all parts of the roof

Regular Professional Cleaning is Recommended

Although it may look like an easy task to clean a roof, it is in fact a specialized job that should be handled with care. Roofing contractors and companies have the correct equipment and high quality cleaning supplies to do the job correctly, while also ensuring that no damage occurs to your roof during the process. While it can be tempting to hire a pressure cleaner to do the job yourself, this is not recommended, as it can not only damage the surface of the roof; it can result in leaks appearing at a later stage as well.

Cleaning Your Roof After a Storm

The weather can be unpredictable at times, and things like high winds can leave debris trapped on your roof. While it’s recommended that you have your roof cleaned regularly by a professional, you should consider additional cleaning after significant weather events. This is especially true if your home is located under trees that may drop limbs, leaves, or other debris. If left uncleaned, it’s possible for pests and animals to build nests from this debris. Eventually, those pests may cause damage to the structure of your home.

Cleaning and Inspection in One

Some roofing companies may offer a service in which they’ll inspect your roof for problems as they clean. This only makes sense; after all, they’re experts who are already on your roof. As they clean, they’ll make note of any potential problems, and you’ll have the option of having those problems repaired. Remember that it’s always best to resolve roofing issues early on to prevent potential disasters – such as major leaks – later down the line.

The Dangers of DIY

DIY roof cleaning is strongly not recommended. Identifying the type of infestation and knowing how best to handle it takes years of experience and certified training. Working at extreme elevations can also put you in danger of personal injury should you fall from a ladder or roof top. Improper roof cleaning can cause significant damage to your roof and could end up costing you more in the long run. Why risk injury and unnecessary expenses with a DIY when the professionals are standing by, ready to clean your roof?

Finding Reliable Dorset Roof Cleaning Companies

Although several companies offer roof cleaning services these days, it’s crucial that you choose a reputable service provider. While this may be difficult if you are trying to obtain quotes on your own, we have simplified the process of obtaining quotes from reputable and accredited service providers.

If you’d like to obtain up to four quotes from various pre-screened roofing companies, all you need to do is provide us with your basic contact information. This will then be passed on to the roof cleaning companies, who will in turn contact you within a day or two at the most.

When contacting you, the various service providers will schedule an appointment to view your property so that an accurate quote can be provided. Always be wary of companies that provide quotes over the phone without seeing your property – chances are that you could receive an invoice for an amount that is far higher than what was originally quoted.

Always Hire Reputable Tradespeople

Before agreeing to have a particular roofer or company clean your home’s roofing, it’s essential to check that they are experienced, insured and reputable.

If you require quotes for roof cleaning near me, all you need to do is fill in our contact form. Yes, it is that easy! After receiving your information, you will be contacted by up to four pre-screened roofers or companies that are reliable and reputable.

When choosing a contractor to clean your roof, your choice should be based on reputation instead of on pricing alone. This will ensure that you have the job done properly and at a fair price.

Keeping Your Warranty Effective

A brand-new roof is quite the investment. In fact, it can cost you thousands of pounds to install a brand-new roof, depending on the materials you select and the size of your home. Most manufacturers will provide you with a warranty on the materials, but Dorset homeowners are often obligated to keep their roofs clean to keep their warranties effective. For example, if your roof starts leaking in the warranty period, the manufacturer may not cover any repairs or replacements unless you can show proof that you’ve had it cleaned regularly. Make sure to check the terms of your warranty, and contact a professional to schedule regular cleaning.

Your Dorset roof cleaning questions answered

Why should I clean my roof?

The black streaks you see on your roof are actually algae growth. This build up can damage the tiles on your roof, as well as increasing cooling costs by holding large amounts of heat in your attic spaces.

Can I just clean it myself with my pressure washer?

You should not use a pressure washer on a roof. While it may get rid of the algae, it can also cause damage to the roof structure and tiles, which can lead to leaks and roof failure. Most cleaning services use environmentally friendly cleaning and low-pressure water hoses.

Is it safe to use chemicals to clean my Dorset roof?

Using chemicals is not recommended on most roof surfaces, since they may cause damage to a number of surfaces. Mild detergent or degreaser is all you need to get rid of most stains on your roof.

Why should I hire Dorset professionals to clean my house roof? The job looks easy enough to do myself.

Although it may look easy, cleaning a roof can be an extremely labour intensive and not to mention, risky task. If you suffer from any health conditions such as vertigo, high or low blood pressure or you are afraid of heights, you could injure yourself severely by attempting to clean your roof. Rather enlist the help of an expert.

How much does roof cleaning cost?

The cost varies based on things like the size of your roof, its condition, and the last time since it’s been cleaned. The best way to determine the cost is to obtain quotes from multiple contractors.

Are there eco-friendly chemicals I can use?

Many of the roofing contractors in your local area specialize in the use of eco-friendly chemicals that can not only clean your roof, but also prevent the regrowth of algae, moss, mould, and mildew. Be sure to put this information in your request for a quote to be contacted by the right contractors.

Are all roofs cleaned the same way?

No. The processes involved in cleaning your roof will depend primarily on the materials used in its construction. A rubber flat roof, for example, will need different cleaning techniques than a roof with asphalt shingles. Your contractor can go over the process with you in detail.

How long will I have to wait for a roofing company to come out and clean my roof?

This will depend on how booked up the roofing companies are at the time that you schedule an appointment with them. In most cases though, you will not have to wait longer than a few days for the job to be done.

Does it take a long time to clean a roof?

The amount of time needed to clean your roof will vary according to the type of roofing material that has been used and the size of your roof. In some cases, it may not take longer than an hour or two, while larger areas may require half a day or a little longer to clean thoroughly.
