Roof Cleaning Nyack Area — Remove Black Streaks Without Damage

Signs your roof needs cleaning: black streaks running down the shingles, green moss along the edges, white or gray lichen spots, and leaves and debris piled in the valleys.

In Rockland County and Bergen County, shade from tall trees and damp air from the Hudson River keep roofs wet. Algae spreads fast in those conditions. Spring pollen and fall leaves add even more.

Do not wait. Moss holds water against your roof and can lift shingles over time. That can lead to leaks. Algae can also make your home look older than it is, which matters if you plan to sell. Cleaning now is much easier than fixing damage later.

Many homeowners in Upper Nyack, Valley Cottage, and Palisades see the first black streaks on the north side of the roof.

We never pressure wash a roof. High pressure can strip the granules off shingles and shorten their life. Instead, we soft wash.

First, we look at your roof, then cover your plants and wet them down. Next, we apply a cleaner at low pressure. It kills the algae, moss, and lichen at the roots. Then we let it work. Some growth rinses off right away. Thicker moss may keep fading over the next few weeks as rain washes it away.

We rinse your gutters, walls, and plants when we finish. Our team uses safe equipment and works with care. Most roofs are done in one visit.

We do not walk on your shingles more than we need to. When we can, we work from a ladder or the edge of the roof.

Roof cleaning cost depends on the size of your roof, how steep it is, and how much growth there is. Thick moss takes more time than light streaks. Two-story homes and steep roofs need extra safety steps.

We look at your roof and give you a quote before any work starts. There is no trip fee. The price we agree on is what you pay. No hidden fees, and no surprise charges.

Regular cleanings every few years can keep the cost down, since less growth builds up.
