Remove Streaks and Protect Your Roof

Roof Top Cleaning in Grand Rapids

Dark streaks running down your shingles are not just cosmetic. That discoloration comes from algae and moss feeding on the limestone filler in asphalt shingles, and it spreads faster in shaded areas where moisture lingers. Homes in Grand Rapids with tree cover or north-facing rooflines see this growth more often, especially after wet springs and humid summers.

New Wave Property Services LLC gently removes algae, streaks, and organic growth from your roof using soft washing methods designed for asphalt and shingle surfaces. This approach uses low-pressure water and cleaning agents that kill growth at the root without damaging granules or shortening your roof's lifespan. Moss removal and algae treatment are included, and the process improves both appearance and durability. In Grand Rapids, where moisture and shade exposure are common, routine roof cleaning helps you avoid premature replacement and keeps your home looking well-maintained.

If your roof has visible streaks or feels rough to the touch, contact New Wave Property Services LLC to schedule a cleaning in Grand Rapids.

How Soft Washing Protects Your Shingles

Your roof is cleaned with a blend of water and biodegradable treatment applied at low pressure, followed by a rinse that carries away dead algae and loosened debris. The work is done from a ladder or the roof edge, depending on pitch and access. Most homes in Grand Rapids take two to three hours to complete, including prep and cleanup.

After the cleaning, your shingles will look lighter and more uniform in color. The black streaks disappear, and the surface feels smoother when you run your hand across it. You will also notice that water sheets off more evenly during the next rain, which means the algae is no longer holding moisture against the material.

This service is safe for standard asphalt roofs and architectural shingles. It does not include repairs, flashing work, or gutter replacement. Moss that has grown deep into seams may require a follow-up treatment if the root system is established. Roof top cleaning is frequently bundled with gutter cleaning to address both drainage and surface protection in one visit.

What Homeowners Usually Want to Know

People often ask whether cleaning will damage their roof, how long results last, and whether the treatment affects plants below. These answers cover the details that matter most before scheduling.

What causes the black streaks on my roof?
The streaks are caused by gloeocapsa magma, a type of algae that feeds on the limestone in asphalt shingles. It thrives in humid conditions and spreads through airborne spores.
Will pressure washing damage my shingles?
Yes, high-pressure washing can strip granules and shorten your roof's lifespan. New Wave Property Services LLC uses soft washing, which cleans effectively without that risk.
How long will my roof stay clean after treatment?
Most roofs stay clear for two to three years, depending on shade and moisture exposure. Homes with heavy tree cover may see regrowth sooner.
Will the cleaning solution harm my landscaping?
No, the treatment is rinsed thoroughly and diluted during application. Shrubs and grass around your home are not affected when standard precautions are followed.
When is the best time to clean a roof in Grand Rapids?
Late spring through early fall works best because temperatures are mild and the roof dries quickly. Avoid scheduling during freezing weather or heavy rain.
