Why Is My Roof So Dirty?

London’s weather and climate creates textbook conditions for moss, algae and lichen growth on the roofs of properties across London. This organic growth causes a number of problems that is very costly to fix. If you’ve notices moss, dirt, grime build up on the roof of your London property you’ll likely want a  quote on roof cleaning. We know London like the back of our hand, having had bases in West London, South London and now Greater London.

Will Moss & Algae Build Up Actually Cause A Problem?

No only does moss growth on a roof can look unappealing but it can also lead to other complications if left unchecked. Gutters and downpipes can become clogged. The added heaviness of wet moss can cause stresses on a roof structure. The repeated freeze-thaw process in winter may cause roof tiles to break which leads to premature degradation of the roof. If left to worsen it could cost a considerable amount of money for roof repairs.  We provide safe, effective roof cleaning and roof moss removal services for homes and business in London.

What Is Your Moss & Algae Removal Technique?

Once the roof has been cleaned the roof tiles will then be treated using a biocide designed to impregnate the roof tiles, stop germination of any moss spores and stop any regrowth. The non-pressure roof cleaning and roof moss removal service we deliver efficiently and successfully removes dirt, grime and algae from your roof. Many roofs can now be cleaned safely from the ground or at the gutter level eliminating the need to walk on the roof, reducing the need for costly scaffolding.

From colleges to office blocks, warehouses to shopping centres, hotels to galleries we deliver commercial roof cleaning and roof moss and algae removal in London and the Greater London area.

Risk assessment and method statements are available upon request.

How will you actually get my blocked gutters clear?

We clean from ground level using high power, high reach gutter cleaning systems.

Although for gutters higher than 40 foot we are trained to use mobile elevated platforms.

Your gutters will be inspected using our live camera system. Then your gutters will be cleaned using one of our super power, high level gutter-cleaning systems. It really is as simple as that.

Our range of high reach vacuuming systems are suitable for industrial, commercial and domestic properties which means we can clean the gutters at homes, apartments, commercial and retail units.

Will you pressure wash the roof?

No! Softwashing is a the new and vastly superior method of cleaning surfaces such as roof tiles. With pressure washing there is a very real danger of damaging the roof tiles beause of the intense impat and high high pressure. Soft washing gently cleans the moss and dirt off the surface of the tile by using a special blend of  ingredients which are sprayed by low pressure onto the affected area, and washed off after the chemicals have killed the moss, dirt and algae

Restore roofs, walls and any other surface where algae or moss has damaged the aesthetics
