Why is moss removal necessary?
Growth is more common in damp, shaded areas. It can accumulate around roof joints, gutters and drainage points. Regular inspection and gentle cleaning help identify damage early and keep the roof looking good. The need for cleaning and its frequency depend on the covering’s type and age, the amount of growth and the surrounding conditions.
Removing moss from a bitumen shingle roof
Bitumen shingles have a protective granule surface, so the cleaning method must be chosen with particular care. We take a gentle approach, using suitable tools without aggressive mechanical scrubbing. Before starting, we assess the roof’s condition, safe access and the areas with the heaviest moss growth.
After removing the moss, we can offer treatment with an anti-moss product suitable for the covering, where needed. Treatment does not repair damaged roofing and is not a substitute for fixing leaks.
Why do we advise against aggressive pressure washing of bitumen shingles?
A powerful water jet or intensive scrubbing can dislodge protective granules, lift shingle edges or damage roof details. We therefore use a gentler approach on shingle roofs, taking account of the manufacturer’s instructions and the roof’s actual condition. Without specific measurements, we cannot promise a precise service life or percentage of granule loss.
How is the roof cleaned?
- Inspection. We assess the covering’s condition, growth, access and work safety;
- Gentle cleaning. We remove moss and other growth using tools suited to the roof covering;
- Gutter check. We check that loosened growth has not blocked the gutters and clean them by agreement;
- Additional treatment. If necessary and suitable for the roof, we apply an anti-moss product according to its instructions;
- Ongoing care advice. We report any damage noticed and recommend when to inspect the roof again.
Anti-moss roof spray treatment
Spray treatment can help limit new growth, but the outcome depends on roof condition, climate, shading and the product used. If the roof has a thick layer of moss, spraying alone may not be enough: the need for physical removal must be assessed first.
We use anti-moss products in accordance with their labelling, safety requirements and applicable regulations. Surrounding plants, drainage systems and the environment must be protected during the work.
Anti-moss roof spray treatmentCleaning tile and metal roofs
We also clean tile and metal roofs. The most suitable method for these coverings may differ from shingle cleaning: the surface coating, age, manufacturer’s instructions and risk of damage must be considered. Pressure washing is not suitable for every tile or metal roof.
Gutter cleaning and minor roof repairs
During cleaning, we may notice blocked gutters, loose fixings, damaged flashings or other problems. We inform the customer of our findings and, by agreement, offer gutter cleaning or appropriate repairs.
Regular roof care
Inspection frequency depends on the roof’s condition and surroundings. Particular attention is worthwhile after strong winds, prolonged rain or winter. Timely moss removal, gutter cleaning and minor repairs can help avoid larger repairs, but we cannot guarantee a specific number of additional service years without assessing the roof.
If a bitumen shingle roof is technically suitable, a separate Shingle Rejuvenator service may also be considered. This does not replace leak repairs; suitability and warranty conditions must be assessed separately.

Gutter guards — clean gutters all year round
Gutter guards prevent gutters filling with leaves, eliminating the need for annual cleaning, and protect downpipes from blockage. Once guards are installed, maintenance is needed only every four to five years, and they can last up to 15 years. Guards can also be installed only in sections where leaves accumulate.
Roof safety
Roof work is carried out using standard industrial rope-access safety equipment and a vehicle-mounted access platform.
Frequently asked questions
Can moss removal damage bitumen shingles?
An unsuitable method can damage the covering. We therefore assess the roof first and use a gentle approach. Even gentle cleaning can pose a risk to a very worn covering; we explain this before starting.
Is roof spray treatment alone enough?
Where growth is light, chemical treatment may be suitable in some cases. For thick moss, the need for physical removal generally needs to be assessed first.
Is the anti-moss product safe for plants?
Safety depends on the particular product and conditions of use. We follow the labelling and necessary precautions, including protection of surrounding plants.
Can you check the gutters while cleaning the roof?
Yes. By agreement, we inspect and clean gutters and report visible damage.
What do I need to provide?
For roof washing, you need to provide access to running water. We bring our own ladders and other tools, although we sometimes accept the use of a customer’s ladder.
Is an access platform needed to wash a roof or façade?
We almost always use an access platform for roof washing. For moss removal from a shingle roof, we use rope-access equipment, so it is important to be able to establish safe anchor points on the roof and on the ground. We arrange delivery of the access platform to the site.
