In case of "house" scrubbing

As long as you do not feel dizzy, if your roof is flat and low, you can perform the defoaming yourself with a stiff brush and water. To complete the operation, spray the roof clean with algaecide and water repellent.

Remember to empty the gutters of everything that is likely to clog. Be careful not to clog it with the lichen you have just pulled off. And if branches encroach on your roof, consider pruning them.

To know:

  • Do not go up never on the roof alonebut work instead at two or three, a person staying on the ground in case of trouble. Do not forget to bring a laptop
  • Above all, equip yourself with a ladder specially designed for mounting on roofs. Plan a height above the top of the roof of 4 to 5 rungs, which you will never climb for stability issues.
  • The safest is contact a professional.
