Frequently asked questions
The work and your roof
Will the drone damage my roof?
The drone never touches the roof. Pressure and nozzle are matched to the material — low pressure on fibre-cement and older coverings. Most roof damage during cleaning comes from someone walking on it, and we do not do that.
Which roofs can be cleaned this way?
Sheet metal, tile and fibre-cement roofs. The pressure and the nozzle are chosen to suit the material, not the other way round. If the material will not take pressure washing, we say so before the work starts, not after.
In what weather can you not work?
We do not fly in strong wind, rain or sub-zero temperatures. The season runs April–October. If the weather postpones a job, we reschedule at no extra cost.
How often should a roof be cleaned?
That depends on the house, not on the calendar. Moss comes back faster on roofs that sit in shade, have trees close by, or have north-facing pitches. The roofing material matters too. The surest sign is the roof itself: once you can see moss, it is time.
Will the garden be damaged?
No scaffolding and no lift means nothing heavy comes into the garden. Light equipment and the crew stay on the ground. We look the surroundings over before the work and agree where the equipment will stand.
What cleaning product do you use?
We name the product we will use on your property in the quote, together with the Estonian biocide authorisation it is permitted under. We do not name a product before that.
Do you need water and power on site?
The quote says whether we need anything from your property, and what. We agree it before the work starts, not on the day.
How long does the work take?
We give the duration in the quote, for your property specifically. We do not publish a general figure: it depends on the property, and we have no measurements of our own to stand on yet.
Price and booking
How is the price worked out?
Roof and facade cleaning are priced by the square metre, from the published price. Windows, solar panels and guttering are priced per property. All prices exclude VAT, and the exact price is set out in the written quote.
Is there a minimum charge for a small job?
Yes. The smallest job we take is €450. Below that the trip and the setup do not pay for themselves. The price excludes VAT.
Where do you work?
We are based in Tallinn and Harju county and work across Estonia. Give us the address when you ask for a quote and we will tell you when we can come.
Authorisations and documents
Are you allowed to fly over houses?
Yes. We hold an operational authorisation from Transpordiamet covering flights over houses and built-up areas. We send a copy of it on request.
Is the work insured?
Yes. We carry third-party liability insurance for the work. We send proof of it on request, including before you book.
What do you supply to a housing association or a commercial client?
A copy of the operational authorisation, proof of liability insurance and a site-specific risk assessment. Ask for them with the quote and they arrive in the same email as the price.
