Coating a Corrugated Roof
A corrugated roof covered in moss and lichen was cleaned and coated in a silvery-white finish that protects it from the weather.
Step by step
1. The roof before
The sheets had darkened and were covered in moss and lichen, which hold moisture on the surface.
2. Up close
On the ridges of the corrugations the dirt had built up into a thick layer.
3. Cleaning
The roof is washed until the dirt and lichen are gone. The coating only bonds to a clean surface.
4. First coat
The coating goes on the ridges and the joints between sheets first, then over the whole surface.
5. The difference
The difference is easy to see here: the finished part at the top and right, the old surface at the bottom left.
6. Right to the edges
The coating goes right up to the wall and around every obstacle, so no spot is left bare.
7. The result
One even, bright surface that reflects the sun and protects the sheets from the rain.
