The Roof Shampoo® Difference

Common roof-cleaning methods like using chlorine beach and high-pressure power washing can damage your shingles, flashing and underlayment. To protect your roof, our technicians choose Roof Shampoo® to effectively remove algae, moss and lichens. This eco-friendly solution is suitable for asphalt and fiberglass shingles and doesn’t contain harmful bleach or phosphates. It also doesn’t require high-pressure power washing, scrubbing or brushing. Best of all, this solution won’t hurt your plants or vegetation. This makes Roof Shampoo® a safer, smarter cleaning method.

What Causes Roof Stains?

Green or dark stains or streaks on your roof can be caused by algae, moss or lichens. While algae might look bad, it doesn’t typically cause damage to shingles; however, moss and lichens can penetrate shingles and potentially cause structural damage.

Sometimes a roof may have stains only on one side. These organisms thrive in moisture and tend to grow on roof slopes that don’t get a lot of sunlight, such as the north-facing or shaded areas.

Fuzzy, green moss growing on your roof can lead to ugly, green stains. Algae can cause ugly, black stains and lichens can leave an ugly, white film. That’s a lot of ugliness on your rooftop. Roofs in regions with humid summers are even more susceptible to these organisms, and growth is more common on roof slopes that don’t get much sunlight. Algae usually won’t damage your roof, but moss and lichens can damage shingles and lead to wood rot and leaks when left untreated. This can severely shorten the lifespan of your roof.

Fixing an ugly roof and extending its life might be as easy as cleaning it. Unfortunately, many traditional roof-cleaning methods also potentially cause roof damage. Adam Quenneville Roofing & Siding in South Hadley, Massachusetts, recommends Roof Shampoo®, a safe, effective roof-cleaning alternative.

THE ENEMY! Moss can damage your shingles if left untreated, leading to wood rot and leaks.


The organic materials in your shingles act as a food source for organisms like algae, lichens and moss. By cleaning your roof with Roof Shampoo®, we can put an end to roof stains and prevent damage.

  1. Moss and lichens can penetrate your shingles and roof deck, causing wood rot. Moisture can penetrate cracks in the wood and create an environment friendly to mold growth. Roof Shampoo® can help prevent permanent damage to your roof deck and help you avoid having to make any costly roof repairs. If damage has already been done, Adam Quenneville Roofing & Siding provides professional roof repair and maintenance services to Massachusetts and Connecticut homeowners.
  2. A stained roof can lead to cancellation of your homeowners’ insurance policy. Untreated roof stains are seen as a risk to insurance companies, because they can negatively impact the integrity of your roof and eventually lead to mold growth inside of your home. By calling on the professionals at Adam Quenneville Roofing & Siding to clean your roof, you can protect your roof and your own peace of mind.
  3. If your roof is covered in algae or moss, sunlight will not be properly reflected. Your shingles will absorb heat from the sun’s rays, therefore heating your attic and increasing your cooling costs. Roof Shampoo® can safely and gently remove staining and restore your roof’s health and efficiency.
  4. A professional roof cleaning done the right way can help you avoid a re-roof when it’s not really necessary. Roof replacement is a costly job, but Roof Shampoo® can improve the look of your roof, as well as remove organisms that can deteriorate your shingles and roof deck, therefore prolonging the life of your roof.
  5. A stained roof is ugly. Whether you are trying to sell your home or just trying to maintain curb appeal, Roof Shampoo® is an effective solution to clean your roof and improve your home’s exterior.
  6. Algae, lichens and moss can penetrate shingles, allowing in moisture and potentially causing wood rot. The smell of rotting wood attracts unwanted critters. These critters can eventually make their way into your attic. According to the President of Tennessee Wildlife Management, Inc., animals are attracted to the smell of rotting wood, mold and mildew, because they associate this smell with food and shelter. Roof Shampoo® can help prevent an animal invasion!
  7. Consumer Reports praises Roof Shampoo® as a smart alternative to roof cleaning with bleach.
