Trusted Roof Cleaning That Protects Your Home and Enhances Curb Appeal

Roof Cleaning Long Island & Suffolk County NY

Algae and moss can look unsightly, actively damage your roof, and rob years from its lifespan. That’s where Platinum Power Washing comes in. Since 2017, we’ve delivered trusted roof cleaning services in Long Island and Suffolk County, using a gentle soft wash method that works well for shingles, cedar shakes, and slate.

We follow ARMA- and manufacturer-approved asphalt roof cleaning methods, never using high pressure that voids warranties. This approach effectively kills algae, moss, and lichen without structural harm. Services include debris removal before treatment to ensure optimal application and results. 

Full visual improvement typically takes one to three months, depending on factors such as sun exposure, rainfall, and roof conditions. If moss persists after 60 to 90 days, we provide free follow-up treatments. Bank on us to protect all plantings, siding, windows, and outdoor features. We also pre-and post-rinse landscaping to eliminate overspray risk.

Roof Types and Materials
We Clean Safely in Suffolk County

Our roof cleaning services in Suffolk County cover: 

Asphalt Shingles

Asphalt Shingles

We apply a soft wash solution containing 3–6% sodium hypochlorite and professional surfactants for guaranteed moss and algae removal from shingles. The solution is never rinsed to kill algae and moss naturally over time. Algae and streaks typically fade within 30 to 90 days. This method causes zero damage to shingles and poses no risk to your warranty.

Cedar Shake Roofs

Cedar Shake Roofs

For cedar, we apply a soft wash solution followed by thorough rinsing. Our professional cedar and slate roof restoration process includes a wood brightener after cleaning to restore color and nourish wood fibers. Extra care prevents drying or discoloration. This process requires more labor and, therefore, costs more.

Slate Roofs

Slate Roofs

We use a higher concentration sodium hypochlorite solution with tight overspray control and refined application techniques for slate. Applications occur from ladders or rooflines using refined techniques, never from ground level. We use only soft wash methods to ensure structural safety.

Frequently Asked Questions

Yes, roof cleaning is often a smart first step before considering a costly roof replacement. If your roof has black streaks, moss, or algae, a professional soft wash may fully restore its appearance and function. If we determine the roof is beyond cleaning, we’ll let you know before proceeding.

If your roof is structurally sound but looks dirty or streaked, roof cleaning is usually the right choice. We assess the condition during your free estimate and will honestly tell you if cleaning won’t help. Many roofs that appear aged just need professional treatment to look new again.

Our roof cleaning service targets organic growth such as algae, moss, and lichen—not rust or inorganic stains. Rust removal requires a different chemical process, which is not part of the standard roof cleaning treatment. We’re happy to evaluate specific stains during your estimate.

Just make sure all windows are closed, pets are inside, and valuables are moved away from the exterior of the home. We’ll handle all on-site prep, including taping outlets, pre-wetting plants, and covering sensitive areas. You do not need to be home during the service.

Avoid disturbing the roof surface or trying to rinse it yourself—let the soft wash work over time. Don’t walk on the roof or clean the gutters until at least a few weeks have passed. If moss remains after 60–90 days, we’ll schedule a free retreatment.

We don’t perform roof cleaning in the rain or if rain is imminent. For best results, the roof needs time to absorb the cleaning solution without immediate wash-off. If weather becomes an issue, we’ll reschedule your appointment at no extra cost.

No, gutter cleaning is not required beforehand. We bag or block downspouts during service to prevent runoff into your drainage system, whether the gutters are clean or not. If your gutters are significantly clogged, we may recommend cleaning them afterward.

Spring through early fall is ideal for roof cleaning in Long Island. Warmer temperatures and more sunlight help activate the soft wash treatment and speed up the results. Avoid late fall and winter, when colder weather can limit effectiveness.
