Professional property and facilities support across Glasgow and surrounding areas.
Safety-focused exterior cleaning for homeowners, landlords, property managers and suitable commercial premises. We clean roofs, gutters, driveways, patios, solar panels and uPVC exterior surfaces using a method matched to the material, level of growth and access conditions.
Moss, algae, lichen, traffic film, leaf debris and weather staining can gradually change the appearance of a property. Glasgow's relatively wet climate means many exterior surfaces stay damp for long periods, especially shaded or north-facing areas. Those conditions can favour moss and biological growth on roofs, paving and other exterior surfaces.
Cleaning is not about making every surface look brand new. It is about removing avoidable build-up, improving drainage and presentation, and using a method that does not cause more damage than the dirt itself. Roof tiles, solar panels, uPVC, block paving and stone all need different treatment.
A roof is particularly important because the cleaning method must protect both the surface and the people carrying out the work. Heavy moss can hold moisture, collect in valleys and gutters and interfere with the way rainwater leaves the roof. But aggressive cleaning can also damage tiles, force water where it should not go or create unnecessary risk at height. The right answer is controlled cleaning, not maximum pressure.
To complete the property's exterior presentation, our window cleaning services can cover suitable glazing, while grass and garden maintenance focuses on lawns, borders and planted areas. Each service is assessed on its own requirements.
Not every moss-covered roof is failing, and cleaning should never be sold with scare tactics. The real concern is when growth becomes heavy enough to affect drainage, hide defects, create slippery surfaces or make a property look poorly maintained.
Heavy organic growth can hold moisture against the roof surface and interfere with drainage. Older or already damaged tiles may be more vulnerable to cracking, surface wear or water ingress. Cleaning should therefore be based on condition rather than assuming every roof needs the same treatment.
Algae, moss and organic film on patios, paths and driveways can become slippery when wet. Cleaning can improve grip by removing surface growth, although worn or damaged paving may still need repair.
Moss, leaves and roof debris can accumulate in gutters and outlets. When water cannot move freely, it can overflow down walls, onto entrances or around fascia and soffit areas.
Dark staining, moss and weathered exterior surfaces can make a home or commercial property appear older and less cared for. Cleaning can improve presentation before letting, sale, inspection or general upkeep.
Thick growth can conceal cracked tiles, loose fittings, blocked drainage points and damaged sealant. Once the surface is cleaned, those problems may become easier to identify.
Exterior areas that are repeatedly allowed to become heavily overgrown usually require more time and effort than surfaces that are inspected and maintained before growth becomes severe.
Each service has a different cleaning problem, surface risk and expected result. The guides below explain the method, what customers gain and what property owners should know before arranging the work.
Falls from height and fragile roof surfaces are serious hazards. The correct access method depends on the property, roof construction, height, slope, ground conditions and whether the work can be completed from a safer position.
We plan access rather than assuming every roof should be walked on. Where practical, work can be carried out using extendable equipment or other methods that reduce the need to stand directly on the roof. If access at height is required, the equipment and controls must suit the task.
Tiles, slates, rooflights and sheeted roofs can be fragile. A surface that looks strong from the ground should not automatically be treated as safe to stand on. Falling moss, debris, tools and cleaning solution also create risk below, so the area around the property may need to be controlled during work.
Choose an access method suitable for the height, roof and duration of the task.
Treat roof coverings and rooflights carefully until their condition and load-bearing suitability are understood.
Keep people away from areas where water, moss, debris or equipment could fall.
Wind, rain, frost and slippery surfaces can change whether work can be carried out safely.
Biocides are selected and used according to authorised uses, label directions and environmental precautions.
Mechanical cleaning removes the bulk of visible moss and debris, but microscopic biological material and staining can remain on the surface. A suitable post-clean biocide treatment is used to act on remaining biological growth and help delay early regrowth.
We do not treat biocide as a magic chemical or a substitute for physical moss removal. It is part of the maintenance process after the roof has been cleaned.
Biocidal products have authorised uses, application rates, contact times and safety information. They must be used according to the product label. Weather, drainage, nearby plants, pets, people and adjoining property all need to be considered before treatment is applied.
Because roof material and product conditions matter, the treatment used must be suitable for the surface. Our standard roof-cleaning process includes post-clean biocide treatment where those requirements can be met safely and lawfully.
Remove the bulk moss and loose debris before relying on chemical treatment.
Use a biocidal product authorised for the intended use and compatible with the surface.
Follow the product label rather than guessing a stronger concentration.
Consider gutters, plants, pets, people, adjoining property and run-off before application.
Wase Support Services provides roof and exterior cleaning as part of a wider property-maintenance service. The work is planned around the material, access, condition and real purpose of the clean rather than applying one machine or one chemical to every property.
Our approach separates roof cleaning from hard-surface pressure washing, solar-panel cleaning from roof-tile cleaning, and cosmetic staining from physical damage. That matters because the method that works well on a concrete driveway may be completely unsuitable for a roof tile, solar panel or delicate exterior finish.
We also recognise the limits of cleaning. Broken tiles need roofing repair. Failed gutter joints need repair. Electrical solar faults need the right solar or electrical professional. Cleaning should improve the condition and presentation of a surface without pretending to solve problems outside the service.

Roof tiles, paving, uPVC and solar panels are cleaned differently because they are different materials.
A suitable biocide treatment forms part of our roof-cleaning process where product and surface conditions allow.
Wase Support Services carries £5 million insurance cover for the services it provides.
We support homeowners, landlords, property managers and suitable business premises.
A professional exterior-cleaning service should know when to use pressure, when to reduce it, when to use chemistry and when cleaning should stop because repair or specialist advice is needed.
Roof access, fragile surfaces, weather, falling debris and the area below the work are considered before cleaning starts.
We do not use aggressive high-pressure washing as the default solution for roof tiles. The cleaning method is matched to the roof surface and condition.
Our roof-cleaning process includes a suitable post-clean biocide treatment where the roof, weather and authorised product conditions allow safe application.
Roof tiles, driveways, patios, solar panels and uPVC are not cleaned as if they were the same material.
Wase Support Services carries £5 million insurance cover for the services it provides.
We distinguish dirt from damage and cleaning from repair so customers know what the service can realistically achieve.

Straight answers about soft washing, roof moss, biocide treatment, work at height, gutters, driveways, patios, solar panels and uPVC.
No. Light moss or lichen can be a normal part of roof weathering. Cleaning becomes more relevant when growth is heavy, affects drainage or gutters, significantly changes the property appearance or the roof needs maintenance before sale, letting or inspection.
High-pressure washing is not suitable as a default method for many roof tiles because it can damage surfaces, disturb weak mortar or fixings and force water and debris into the roof structure. The roof material and condition should determine the cleaning method.
Soft washing uses lower mechanical force than aggressive pressure washing and combines controlled physical cleaning with suitable treatment where appropriate. The exact method still depends on the roof covering, condition, level of moss and safe access.
Our roof-cleaning process includes a suitable post-clean biocide treatment where the roof surface, weather and authorised product conditions allow safe use. The product is used according to its label, including dilution, contact time and environmental precautions.
Physical cleaning removes the bulk of visible moss and debris. A suitable biocide acts on remaining biological growth and can help slow early regrowth. Some residual staining or dead growth may weather away gradually after treatment rather than disappearing immediately.
Biocides must be used according to their authorised label instructions. The surrounding area, drainage, plants, animals and people need to be considered before application. Some products require specific precautions or exclusion periods, so the product instructions control how the treatment is used.
Poor methods can damage tiles, which is why roof type, condition and access should be assessed first. Aggressive pressure, unnecessary foot traffic and unsuitable chemicals can create problems. If tiles are already cracked, loose or fragile, roofing repair may be needed before cleaning.
Not automatically. Roof access is planned around the property and risk. Where practical, work can be carried out from safer positions or with equipment that reduces direct roof traffic. Roof coverings and rooflights should be treated carefully because some surfaces can be fragile.
No single access method is right for every property. The correct arrangement depends on height, slope, roof type, ground conditions, duration and the work required. Suitable ladders, platforms, mobile access equipment or other controls may be needed depending on the risk assessment.
Falls from height are a major source of serious injury, and roof-cleaning work can involve fragile surfaces, wet tiles and falling debris. The work must be properly planned, carried out by competent people and use access equipment suitable for the task.
Yes. Moss and loose roof debris can detach and collect in gutters and outlets. Clearing gutters can therefore be useful alongside roof cleaning, particularly where heavy growth has been removed.
Common signs include overflow during rain, water running down walls, plants or moss growing from the gutter, or visible standing debris. Overflow can also be caused by damaged or incorrectly installed gutters, so cleaning does not solve every drainage problem.
Yes. We clean suitable driveways, patios and hard surfaces. The method is matched to the material because block paving, concrete, natural stone, resin-bound surfaces and tarmac can respond differently to pressure and chemicals.
Pressure cleaning can remove some jointing sand between blocks. Once the paving has dried, suitable re-sanding may be needed to help restore the joints and support the finished surface.
Oil staining can often be improved with suitable degreasing, but older oil can penetrate porous materials and leave a permanent shadow. We distinguish stain improvement from a guarantee that every mark will disappear.
Yes. Suitable solar panels can be cleaned gently to remove dirt, dust, bird droppings and other deposits. We do not treat solar panels like paving or roof tiles, and manufacturer or installer guidance should be followed where it specifies the cleaning method.
If dirt is blocking light from reaching the panel, cleaning may improve performance. However, low output can also be caused by shading, electrical faults, inverter issues or system condition, which cleaning will not correct.
Not necessarily. Rain removes some ordinary dust, and many systems need only occasional cleaning. Cleaning is more useful where visible contamination remains, such as bird droppings, heavy dust, pollen or persistent dirt.
Yes. Suitable uPVC fascia, soffit, cladding and other exterior surfaces can be cleaned to remove general dirt, algae and weather staining. Permanent ageing, fading or physical damage may remain after cleaning.
Yes. Removing heavy moss, staining and exterior dirt can make a home or commercial property look better maintained. Cleaning is particularly useful before sale, letting or general exterior improvement, but it does not repair damaged materials.
There is no fixed interval for every roof. Roof orientation, shade, nearby trees, surface material, local exposure and how quickly moss returns all influence when cleaning may be useful again.
Roof and exterior cleaning may need to be rearranged when wind, heavy rain, frost or unsafe surface conditions make the work unsuitable. Biocide application also depends on the product instructions and weather conditions required for effective and safe use.
Yes. Wase Support Services carries £5 million insurance cover for the services it provides.
