Roof Shampoo® is a safe, effective roof cleaning alternative

What Causes
Roof Stains?

Do you have green or dark stains or streaks on the shingles of your roof? These stains are likely 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.

How is Roof Shampoo® Different from Common Roof Cleaning Methods?

Common roof cleaning methods like chlorine bleach, the “splash and dash” method, and high-pressure power washing can cause damage to shingles, flashing, and underlayment.

Adam Quenneville Roofing & Siding uses a roof cleaning product called Roof Shampoo®, an eco-friendly solution for asphalt and fiberglass shingles. Roof Shampoo® is a smarter cleaning method that does not use harmful bleach or phosphates and does not require the use of high pressure or scrubbing or brushing. Roof Shampoo® will effectively remove algae, moss and lichens without damaging your shingles or the plants and vegetation around your home.

Ugly but harmless. Black stains on a roof (like in the above photo) are actually from algae. Mostly found in regions with humid summers, algae doesn’t damage the roof, but it will make your roof ugly.

Reasons Why Customers Choose Roof Shampoo® Roof Cleaning

There are many reasons why we trust Roof Shampoo® to provide our customers with a clean roof and superior results.

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.
