ROOF CLEANING ABERDEEN
Clean & Maintain
The roof must be maintained in order for the roof to stay looking clean a moss inhibitor treatment must be applied every 18-36 months where the surrounding area has trees in close
proximity every 12 months. The moss inhibitor is also a hard surface cleaner so you not only get the retardation of moss but it will also clean the roof tiles over time.
THE IMPORTANCE of QUALITY PRODUCTS
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

Roof Cleaning Aberdeen
Roof Cleaning removes moss, lichen and moulds form the roof tiles. This is achieved by either a Low Pressure Wash or Softwash roof clean.
What Is Low Pressure Wash Roof Cleaning?
Roof Cleaning using a pressure washer that has a variable control allowing the operative to reduce the pressure as required for the task. The results for pressure cleaning the roof can be
seen the same day as the cleaning.
What is Softwash Roof Cleaning?
This is where the roof is scraped with special tools removing the bulk of the moss before being treated with a premium biocide.
Low Pressure Roof Cleaning:
There are certain roof tiles 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.
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
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.

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
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.
A Few Myths about roof cleaning
There are always a few myths about roof cleaning using pressure washing. 1) It will move the tiles- not correct Interlocking Concrete Tiles weigh between 40-60kg per square metre
natural slate around 30-40kg. 2) It damages the tiles-there is a extremely small loss of tiles surface which is less than 1mm the wind rain snow etc. over time will have removed more than
Is roof cleaning Necessary?
The function of the roof is to protect the property below from the elements. Think of it as an umbrella shedding the rain, snow into the rain water gutters.
The problem with moss is it retains large volumes of water which can over a long period of time degrade the tile below, but it also hampers the direct flow of water off the roof again
keeping the roof wetter for longer exacerbating the issues.
Moss can also block gutter valleys drains which can be costly to resolve and it also falls to ground level with help from the birds or heavy rain which requires continual sweeping up.
Softwash Roof Cleaning
Softwash Roof Cleaning is an alternative to pressure washing your roof.
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.
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
Softwash Roof Cleaning can be time a consuming process depending on the roof thus the roof may require scaffolding which requires a qualified scaffolding company to install. Cost for
scaffolding vary from region to region but you can expect to pay from around £400 a side of the property but this will depend on the complexity of the scaffolding.
The importance of a quality moss inhibitor treatment equates to the longevity of the roof clean. The Moss Inhibitor treatment Cotec use is a high quality, professional-grade product that can
be used in conjunction with power washing as a post-treatment or as a standalone softwash.
