Slate roof cleaning in Port Washington
Port Washington and Sands Point have plenty of slate, much of it with snow guards that need working around with care.
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.

How we clean slate
We explain the process
Before any work starts, you know exactly what we'll do and what to expect.
We protect the property
Plants, gutters and copper get noted and protected. Landscaping is rinsed the whole time.
We soft wash from ladders
Low-pressure treatment applied from ladders. No one steps on the slate.
Weather finishes the job
The slate is not rinsed. Rain clears the dead growth over the next 6 to 8 weeks.
