„Společnost NANO FUSION jsme si vybrali na čištění a impregnaci střešní krytiny, přičemž celková plocha činila 350 metrů čtverečních. Výsledek práce je naprosto ohromující a překročil všechna moje očekávání. Zvláště bych chtěl vyzdvihnout zaměstnance této firmy, kteří prokázali, že jsou skutečnými profesionály ve všem, co dělají a práci měli hotovou za 2 dny! Komunikace s firmou byla rovněž bez jediné vady na kráse. Společnost NANO FUSION mohu bez jakýchkoli výhrad doporučit! “

„Rozhodli jsme se svěřit naši dvacet let starou střešní krytinu Bramac do rukou odborníků z firmy Nano Fusion. Po vyčištění vypadala střecha jako nová, ale její původní barva se nám nehodila k fasádě. Proto jsme se rozhodli pro nový nátěr a výsledek je prostě fantastický! Střecha září jako nová a vypadá úžasně. Pan Nytra, majitel firmy, nás hned na úvod informoval, že používají dvousložkové syntetické barvy místo těch na vodní bázi, což zaručuje maximální kvalitu. Také nám nabídl širokou škálu odstínů na výběr. Jsme nadšeni z našeho rozhodnutí a firmu Nano Fusion vřele doporučujeme!“

More about the service

Why it matters

Moss, lichens, atmospheric deposits – all of these gradually destroy the roof. The longer it is left unattended, the more expensive the consequences.

We use a combination of special chemicals and high-pressure water (up to 350 bar, or hot water up to 80 °C), which allows us to remove even the most stubborn dirt – including their spores. After cleaning, we apply an impregnation that protects the roof for many years.

FAQ

What you ask us most often

Didn't find your answer? Give us a call – we're happy to help.

The roof cleaning process involves using hot high-pressure water, which effectively removes moss, lichens, and other dirt down to the roots, without the use of aggressive chemicals. A cleaned and degreased roof is then prepared for impregnation. We carry out impregnation on a dry roofing material.
Regular roof cleaning not only improves its appearance but also extends its lifespan. Accumulated dirt, moss, and lichens can damage the roof, cause moisture retention, and reduce its protective function. A clean roof means a lower risk of expensive repairs in the future. Regular cleaning combined with impregnation against moss and algae helps to prolong the lifespan of the roofing material.

After cleaning, it is essential to impregnate the roof! Impregnation not only extends the roof's lifespan but also reduces future maintenance costs. It protects the surface from moisture, UV radiation, and the re-accumulation of dirt, as well as the growth of moss and lichens. Thanks to impregnation, your roof will stay clean and durable for longer. However, beware! Not all impregnations are created equal! If someone offers you impregnation for €2 per m2, be sure that it won't be of any quality! A reputable company should inform you right from the start about the type of impregnation they use. Presenting a technical data sheet is a given.

The effect of cleaning and impregnation can last several years, depending on the surrounding conditions (e.g., proximity to trees, dust in the area, etc.).

However, thanks to impregnation, the roof is protected in the long term and is easier to maintain. We have completed projects in Jesenicko and Valašsko, and roofs are still clean after 6 years!

Definitely. We use gentle cleaning methods and professional equipment that will not damage the surface of your roof. Moreover, our experts have many years of experience and always choose the most suitable method according to the type of roof and its condition.

We won't lie to you and will say right away that some risks do exist! During cleaning, it may happen that due to poor flashing of roof windows, water may leak into the room. (Nothing dramatic, but a few drops and streaks may appear.)

If you do not have a protective vapour-permeable membrane under the roofing, expect that some amount of water may seep through. Usually, this concerns older buildings where there is an attic under the roofing, and a few drops of water are not a problem. It certainly won't be as much water as would flow from the attic to the lower floors.

The duration of the process depends on the size of the roof, the degree of contamination, and the weather conditions. We can clean a roof of 300m2 in one day! (10 hours) The following day, the impregnation takes place, which under ideal conditions takes 2 - 4 hours.

Yes, cleaning always includes the clearing of gutters and downpipes. After all, we can't leave the mess that will fall from the roof in the gutters and downpipes :-) During the cleaning, we constantly check the downpipes and regularly empty the catch baskets.

Please always inform us of this fact! In this case, we can choose between two types of procedures:

1. Disconnecting the downpipes and connecting flexible pipes, which we will lead to a predetermined location. We will clear away the resulting pile of moss and debris. Subsequently, we will impregnate the roof after it has dried.

2. We opt for hot water cleaning without the use of cleaning chemicals! We will then treat the roof with a product that will eliminate any spores and seeds of moss and lichen. The sanitisation is carried out with a controlled spray, so it does not run off. After drying, it does not need rinsing and is compatible with subsequent impregnation!

In 99% of cases, we use climbing techniques. We are trained to work at heights and over open depths. Therefore, we carry out the work from a rope. In other cases, such as work on churches and other hard-to-reach roofs, we use a work platform.

You can easily arrange an order through our web form, by phone, or via email. We will be happy to discuss everything with you, answer your questions, and agree on a date that suits you.
