This is why we do not stain cedar roofs.
This roof was pressure washed and a wood preservative was applied with a stain added giving it this homeowner a semi-permanent pink roof. OOPS!
This is not the natural color of a cedar roof....
This homeowner will have to let the roof age and then have it pressure washed to get the stain off. It may take (10) ten years to return to a normal healthy looking shake.
Notice they stained everything. The valley’s, Vents, and the metal flashing around the skylight.
