How do you clean moss from a roof?
Cotec roof cleaners use two systems Low Pressure Wash or Softwash Roof Cleaning.
The unit we use for roof cleaning is set at a lower pressure than your standard pressure washer as all we need is the dirt and moss removed from the roof. The inhibitor treatment will kill any residual biofilm and continue to clean the roof for the follow 12 months.
There are certain roof tiles (Rosemary Clay Fibre Cement) that do not benefit from low pressure cleaning so for these roof tiles we would recommend softwashing but we would advise which is the best solution to clean the property roof.
Low Pressure Wash Roof Cleaning:
Pros: Same day clean-night and day results
Cons: Messy Job and there is always the chance of a water leak.
Softwashing is scraping the roof removing the bulk of the moss before applying a premium inhibitor treatment some roof can be treated with a cleaner if a quicker result is required.
Softwash Roof Cleaning:
Pros: The works are not as messy as pressure washing. There is no chance of water leaks
Cons: The product can take up to 1 year to work. Roof only look a little better on the day of the clean.
Low Pressure Roof Cleaning:
Cleaning is carried out in two stages: 1) The roof is washed using our low pressure jet wash which removes the bulk of visible dirt lichen and moss. The roof is then rinsed of all debris before the next step. 2) The second stage is the application of a premium inhibitor (residual cleaning properties) at the correct dilution rate according to the manufactures instructions killing any residual spores. The application of the inhibitor is essential as it will slow the regrowth of moss lichen etc a reasonable expectation is that the roof surface will be biofilm free for 18-36 months before a second treatment is required.
Roof Cleaning the Works Sequence
Arrival on Site
This is normally 8am. We will contact you a few days prior to our arrival. The weather can delay roof cleaning but we would always advise you if we could not start works. Works can last up to 3 days depending on the roof size.
Low Pressure Wash
The roof is washed from the top down. The
work is never rushed. Once the roof is free of
moss it is rinsed.
Happing Up
The property is happed up to protect the
customer garden and catch the moss. Down
pipe filters are also fitted. It may necessary to
hap your neighbours garden depending on
the proximity to your property. Roof cleaning
can be a messy job so all garden furniture
plant pots etc. should be moved away from
the house. It is advisable to move any cars
from the driveway (neighbours may need to
move their cars) It is always wise to advise
neighbours of the proposed works.
The Clean Up
Gutters are cleaned out and filters removed.
The moss is collected into bins for removal
off site. The building is rinsed down from the
top facia soffits wall windows doors removing
any overspill. The ground area is also rinsed
leaving the area clean and tidy
Moss Inhibitor
The final stage of the works is to apply a
premium moss inhibitor which will kill off any
remaining spores and prevent regrowth for
up to 36 months.

Softwash Roof Cleaning
Softwash Roof Cleaning
This system can take up to 1 year to fully clean the roof but results should be seen within a few months. We use a professional concentrated cleaner for
removing natural growths such as moss spores algae or mould from roof tile surfaces.
Benefits:
Does not require rinsing.
Treats roof tile surface with no risk of staining and damage
Contains no acids or bleach
Can also have some residual benefits.
The moss is normally always cleaned from the gutter level with telescopic tools unless scaffold is erected. The downpipes are protected against blockage beforehand. Tarpaulin is laid to receive the falling debris and gutters are cleaned out before the biocide is
applied.
The roof is scraped from the gutter level using special tools. The bulk of the moss is removed from the roof but small moss particles and white lichen will still be obvious at the end of the cleaning process. However, the biocide treatment will do the work killing
the biofilm over time. The roof will self-cleanse but this varies with numerous environmental factors.
Roof Cleaning Tool
The roof 8 months after the initial Softwash treatments.
The bulk of the moss is scrapped from the roof before
the Softwash solution is applied by spray or brush
The roof before the Softwash works
Fully biodegradable
Does not bio-accumulate
Ph neutral, so safe for materials and gentle on people
Controls algae, lichen, fungi, moss and mould
Non-bleaching (contain no bleach or acids)
Not affected by hard or mineralised water
Harmless to all known building materials
System 1) A hypochlorite based softwash biocide which at 5:1-10:1 dilution is classed by the EU, PCD and HSE as non corrosive or
hazardous to people or the environment. This solution contains no acids or solvents does not bio-accumulate and the surfactant is fully
biodegradable and after use it quickly breaks down into tiny amounts of ordinary salt and water

I have used Cotec twice now over the past 6 years and cannot recommend them highly
enough. They undertake the work to a very high standard and the clean up operation
was exceptional. Sam even came back at a later date with a replacement tile that he
had discovered to repair a slightly cracked one in my roof. There are a number of
companies advertising similar services but I would be surprised if anyone can match
this standard. All work completed as per the Statement of Work, on time and at the
agreed price. I will certainly be using them again in two years time when the roof needs
cleaning.

The roof should be treated with inhibitor at least every 3 years in order for
the roof to remain biofilm free. The failure to maintain the roof will result
in the return of moss and lichen

Delivering the finish that customers expect is our number one goal. Why? it leads to future busines and satisfaction for us on a job

We have been cleaning roofs for well over 10 years from bungalows to mansions so have gain a wealth of experience of the
different stituations that can arise and how to overcome any issues. Our pricing sturture is fair and based on the roof size,
complexity of the roof and tile type.
The cost of roof cleaning is determined by the size of the roof tile type and the complexity of the works and whether it is a Low Pressure Roof Clean or a Softwash Roof Clean

This up and over roof is the simplest roof to clean. The factors that would contribute to the cost here are the size and volume of moss. The general cost for Terrace and semi-detached are £550-£7500 This would also include the cost of
a premium inhibitor treatment.

The cost of roof cleaning can be between a few hundred pounds to a few thousand pounds.
Customers can choose between Low Pressure Wash and Softwashing but it sometimes depends on the
roof contamination and property position as to which is the most suitable cleaning system. Low Pressure
Wash roof cleaning costs are slightly less than Softwash cost but not by much
What is the Cost of Roof Cleaning?
Why Does the Volume of Moss Change the Cost?
When the moss is taken off site we need to tip the moss at a Waste Disposal Centre. The council for the
region set a charge by weight tipped. We are a registered waste carrier.
