Work Method

How do we clean your roof?

We work systematically and safely using modern gear and harness fall-protection.

1. Inspection

We check the roof condition, identify cracked tiles, and make sure battens and sub-roofing felt are intact before starting.

2. Pressure Washing

We clean the roof tiles from top to bottom with custom water pressure, removing all moss, dirt, and lichen without damaging the glaze.

3. Anti-Algae Spray

We spray a biodegradable anti-algae solution. It penetrates deep into the tile pores to kill microscopic roots and spores.

4. Cleaning Up

We clean gutters from washed debris and pick up all fallen waste around the house, leaving your property in pristine condition.

FAQ

Frequently Asked Questions

Moss acts like a sponge, retaining water against the roof tiles. During winter, this water freezes, leading to frost cracks. Frost damage breaks tiles and allows moisture to reach the wood framing, causing rot and leak damage.
A roof that is mechanically cleaned and treated with algicide stays free of moss and algae for about 4 to 6 years, depending on nearby shade and trees. We recommend preventive treatment every 5 years.
No, when executed correctly by professionals. We calibrate water pressure according to the tile age and type (concrete or clay), and we always wash downward to prevent water from pushing beneath the tiles.
Yes, absolutely. During washing, moss drops into the gutters. We clean all gutters and check that downspouts are clear before finishing the work.
