Roof cleaning - the detail

Moss and lichen growing on roofs and on old buildings is sometimes seen as conservation but the problem is that in harsh weather these plant forms retain water that freezes and can cause cracking in your roof tiles. So these growths or "biofilms" should be cleaned off. In addition moss and lichens can grow into the drainage channels between the roof tiles, stopping them from freely draining water towards the gutters with the result of quite small leaks, most of them undetectable on your plaster ceiling. However, over a long period of persistent leaking some of this water seepage and moisture will rot your roof timbers causing additional expense in the long term. We regularly see slipped and cracked clay tiles caused by the freezing/thawing process.
Because the root systems of these plant forms are so invasive they can cause damage to the structure of your home, so eliminating them will save you thousands in repair bills in the future.
We can do roof cleaning Birmingham by removing roof moss and lichen without walking on your roof. Roof walking is a serious hazard and we take the worry of accidents away from the situation by not walking on your roof. This way there is no risk of cracking tiles and no risk to us as workers so you can have peace of mind.
For a two storey home we work from a ladder correctly secured to the wall using safety bolts, so in this way everyone is safe. For a single storey home we work directly from the ground.
Our cleaning products are applied using long carbon fibre liquid fed poles and a fine soft wash spray so no damage will be caused to your roof.
This roof cleaning process does not use harsh chemicals that are corrosive to any metal flashings and will not stain the exterior paintwork of your home.
Our application is low pressure therefore cleans and restores old clay, concrete, or slate tiled roofs without causing any physical damage.
If your roof is covered in grime, moss and lichen it can ruin the street appeal of your property.
Roof cleaning must be one of the smartest things you as a homeowner can do to protect your investment. So in the end your roof looks great and a well maintained home reflects well on you the owner.

Damage to tiled roofs from High Pressure Cleaning

Clay tiles can be very brittle and slate even more so. Its dangerous up there.
We have systems that can spray your roof with a low pressure spray without necessarily walking on the roof.
Being careless about walking on a terra cotta roof will result in cracked tiles just like the picture below

Roof Cleaning - Soft wash system

Roofs come in different forms and understanding the structure of your roof is the crucial first step to determining how to use soft washing to clean it. The basic roof styles are tiles, slate and metal in various forms. Out of all of these roof finishes the one that has pores or an open structure that’s highly convenient for dirt and grime to collect and for organic life forms to inhabit, are concrete tiles

These roof tiles can be deeply porous, hard or soft tiles and with a surface that can be soft to the point of being powdery where even a light hosing will leave marks, so high pressure cleaning can leave permanent scars.

If a film of moss, lichen and algae has developed and weakened the surface, then its even more susceptible to permanent marks if pressure cleaned.

Every day of the week your roof is subjected to a wide range of hostile weather systems, from freezing temperatures to rain and wind promoting erosion of the surface, with rain in some instances keeping the roof wet for extended periods of time, especially on surfaces with minimal sun exposure.

Care is always needed when soft washing and in this assessment phase, as consideration needs to be given to the composition of the roof tile, and try to establish if the roof has been pressure cleaned before.

Cleaning with a biocide can expose previously pressure cleaned roofs with ugly marks across it that is not due to the biocide cleaning, and sometimes a homeowner can be completely unaware of this previous damage.

Biofilm are what we are trying to eliminate when soft washing, they are an organic mix of algae, lichens, moulds, fungi and mosses. Their make up on any roof surface is as varied as the number of surfaces out there. Around our built environment, they live on sandstones, brickwork, roofs of all types, walls, driveways and paths, fences and decking and can make our lives hazardous.

Some individual species in the biofilms could be lichens that are in fact classed as endangered species. This has been the case with the high amount of pollution in the environment causing the acid rain that destroys these plant forms.

However, things are changing with cleaner vehicle emissions, generally cleaner air, and bans on certain pollutants means that some lichens are making a comeback. So an unexpected result in some ways has resulted in much more aggressive biofilms on roofs sometimes when and where we least expect it and usually where it is inconvenient, causes damage, downright dangerous or just spoils the roof.

We don’t do soft washing on monuments. By definition they are usually in an area of historical or archaeological importance and is not our area of soft washing expertise, and biofilms on ancient monuments or gravestones may contain endangered species of lichens. There is an opinion out there that biofilms including lichens and moss are an attempt at conservation or preservation, even to the point where the biofilm can damage the roof of a building, causing leaks, there is a resolute stubbornness to accept the plain truth that biofilms in forests, ancient monuments or ancient woodlands where nature intended them to be are just great.

However pro green you may be, you may live in a home that might be manufactured from unsustainable sources, there is overwhelming evidence acknowledging that biofilms can have an adverse affect on our homes and health. Moulds are part of this ecosystem and have been shown to give great discomfort to sufferers with bronchial problems and asthma.

Control of biofilms in the built environment, inside and outside our homes, should be done sensibly to enhance our lives but giving thought to the natural environment around us.

Biofilm Development
Lets specifically talk about roofs.

The first phase of biofilm development is the accumulation of grime, simple dirt. If the surface of the roof was a tight packed very dense polished surface then pollens, spores and other forms would not settle so easily. However, roofs are very open and roof tiles are porous and provides the perfect haven for the accumulation of mould and algae.

Even so the filaments of aggressive fungal form may only penetrate to 0.5mm depth into the roof tile , however if not remove intelligently, they marking they leave behind can be very noticeable. The overlaps between roof tiles are a great place for algae and moss to hang out. In the shade, very damp and a great breeding ground for all types of algae, moss and fungi.

High pressure cleaning just cannot remove this growth whereas a eco biocide spray will kill it off and the weather will wash it away.

Soft washing the roof will in time result in all the Biofilm being treated even in between the gaps in the tiles and other hard to get to spots.

Roof cleaning and removal of Biofilms - what we do
Roof biofilms are a complex mix of dirt, lichens, algae and fungi. Its invariably difficult to establish what the main colony is composed of so its often the best procedure to treat for the worst case scenario. This is usually the most difficult biofilm inhabitant to remove being lichen.

A thorough soaking is usually required. Enough biocide is applied to soak the roof ensuring that the overlaps between the tiles is flooded.

Most roofs are a black colour comprised of grime, black lichen and metabolites. Metabolites are a by-product of fungi that grow on roof tiles. The fungi feed on the minerals (bio mineralisation) in the roof tiles and secrete a substance like a sunscreen to protect them from the sun and to help them colonise even more territory.

Metabolites are really tough to deal with. The fungi is killed off easily, but the metabolites may require a second treatment of an alkaline gel or spray. In about 6 months they will fade away as the natural action of the weather will wash dead bits away.

Self cleansing is important to the overall process of biofilm removal. In other words it gets better with time.
