Those dark streaks and green patches on your roof are not just dirt. They are living growth, mostly algae, and sometimes moss or lichen. It spreads, it holds moisture against your shingles, and it makes the whole house look tired. Gold Star Pressure Wash cleans roofs in Roslyn, Westbury, and the towns around them with a soft wash. That means low pressure and a cleaning solution matched to your roof. Gold Star is licensed and insured, and we clean all types of roofs.

We look at the roof material, how heavy the growth is, how steep the slopes are, and what sits below, like plants, windows, and outdoor units.
We work carefully around plants and landscaping near the roof.
A cleaning solution goes on at low pressure and does the work of breaking down algae, mildew, and stains.
We look over the whole roof for missed spots before we pack up.

High pressure can knock the granules off asphalt shingles and force water under them. That shortens the life of a roof you paid a lot to install. Soft washing avoids that. The cleaning solution does the work and kills the growth, so nothing gets blasted off your roof. The result looks cleaner and the roof is treated gently.

We clean all types of roofs, including asphalt shingle, cedar, slate, tile, and metal. Each material needs its own care, so we plan the soft wash around yours.


Our climate is perfect for roof algae. Humid summers, damp springs, and shade from mature trees keep roofs wet for long stretches, and algae loves that. North facing slopes, roofs under oaks and maples, and homes close to the water tend to stain first. In the neighborhoods around Roslyn and Westbury, with older wooded lots in Old Westbury, Brookville, and Muttontown, we see it often.
On larger North Shore homes, the roof is one of the biggest things you see from the street. Dark streaks make a good house look neglected. More important, the growth holds moisture against the shingles over time. Cleaning the roof on a regular schedule is a lot easier than replacing it early.
Roof washing and gutter cleaning go well together. Leaves and debris on the roof end up in the gutters, so many homeowners book both. Solar panel cleaning is a separate service that you can book on its own.

We look at your roof, the amount of growth, and access, then give you a free estimate. Before we start, we look over the roof and the areas around it, and plan the job with care around plants and landscaping.
We apply the soft wash solution evenly across the roof. The solution needs time to break down the growth. Heavy moss gets a second pass, and we will tell you up front if yours needs one.
We check the roof and the ground around the house before we wrap up.
Those streaks are usually algae. It grows in damp, shaded spots and spreads down the roof with rain. Moss and lichen show up as green or gray patches, and heavy moss gets a second pass. All of them hold moisture against the shingles, which is why they are worth removing.
Done right, yes. We use a soft wash with low pressure instead of blasting the roof, because high pressure can strip granules and damage shingles. Always make sure whoever cleans your roof uses a low pressure method.
It depends on shade, moisture, the roof material, and how fast growth returns. Shaded roofs under trees usually need attention sooner than sunny ones. If you can see streaks from the street, it is time to call. We can look at your roof during the estimate and tell you what makes sense.
Yes. Gold Star is licensed and insured, and we clean all types of roofs. We also work carefully around plants and landscaping, so tell us about anything delicate, like a garden bed or a pond, when we meet.
Spring through early fall is usually best, because mild temperatures help the roof and the surrounding areas dry properly. Many homeowners wash in spring to clear away winter buildup, and others wash in early fall before cold weather.
The price depends on roof size, slope, access, and how muc
