Slate roof cleaning in Garden City
Garden City's Tudors often carry thick, textured or multicolor slate. Both of these jobs had heavy lichen. Both came back to their original color without anyone stepping on the roof.
We soft-wash slate from ladders and never walk on it. No pressure washing, no scraping. Most roofs look 80 to 90% better the day we finish.
