Before during and after shot of a treated roof in Athgarvan Co.Kildare. The old slates were so badly contaminated with moss and algae that their true colour was completely hidden.

As roofers we know, and have seen first hand the damage caused by high pressure roof cleaning and inexperienced people on roofs.
 


Our low pressure cleaning techniques have been developed over the last 30 years and are intended for the use of experienced roofers to treat roofs and other external surfaces effected by moss, lichen and algae, safely and in a non-aggressive manner to prolong the life span of materials and ensuring their optimal performance.

The First Rule of Roof Maintenance:
Keep the roof clean so water can drain quickly and surfaces dry faster.
 
Eco-friendly and 100% effective every time.

Step one: The entire roof surface is checked for damage and any necessary repairs made.
 
Step two: All, or up to 90% of moss and other growths are removed by hand to prevent guttering and down pipes from blockages.

Step three: The roof surface is treated using our specially developed surface biocide to ensure any remaining spores die off and their reproductive cycle broken to ensure longevity of results.

Step four: All guttering, soffit and fascia are cleaned and a full site clean up takes place.

F.A.Q.
Why is there noticeably more moss growth on roofs nowadays than in the past?

The answer to this is simple- cleaner air!
Over the past number of years governments have worked hard to reduce their carbon foot prints and in doing so have made the air we breathe cleaner. The evidence of this can be seen on roofs throughout the country by the increasing moss and algae growth.  In the past the pollutants present in the air acted as a killer to these organisms and prevented their growth in many areas.

Will my guttering and down pipes become blocked after treatment?

No. We remove all or up to 90% of the growths by hand first. Any remaining growths that later die and fall away are so small that they will wash safely through any guttering and down pipe system. In fact, gutter cleaning will become a task you needn't worry about for a long time after!

How much does it cost?

There is no set price for our roof cleaning service. Every roof we clean differs in some way, the labour involved in moss removal, accessibility  amount of product needed to name a few. 
We do though offer a free consultation and pricing with absolutely no obligation or hard selling. So why not drop us line.  

What strength pressure washer do you use? 

We do not use any type of pressure washing equipment when cleaning roofs.
A typical medium sized electric pressure washer delivers around 1500-2000 psi, your more powerful petrol or diesel washers can range to anything from 2000-10,000 psi for an average sized machine.
Our spray box works at a max pressure of 50 psi, that's less than a typical garden hose.

How long will it last?

Again this differs from building to building. The product we use will continue to clean the roof surface for a period of up to two years, after which contamination will return but at a rate that depends on a number of factors. Surrounding area, weather conditions, type of roof surface etc... 
A general rule of thumb we would use for a building built in last 20 years would be to take the age of a building, estimate the number of years the moss growth has been an issue and subtract.
Example. A 10 yr old house with moss issue for 4 yrs.
10 - 4 =6 plus 2 yrs cleansing period = 8 (estimated time it would take for moss to become an issue again is 8 years.)
