Is Roof Washing Safe For My Shingles?

roof cleaning service

At TLC Exterior Cleaning Services, Inc. we only use the methods approved by the Asphalt Roofing Manufacturer’s Association (ARMA) and the leading shingle manufacturers.

Roofs must be cleaned with a gentle, soft wash. Our ARMA approved, non-damaging technique along with our unique cleaning formula ensures that your roof is clean and algae free for YEARS! Don’t risk your expensive roof by using the wrong cleaning methods!

TLC Exterior Cleaning Services, Inc. also takes great care in protecting the landscaping around your home while cleaning your roof. We bag all downspouts and we cover all bushes. We either cover or thoroughly rinse all plants and trees keeping them properly protected throughout the cleaning process.

Some companies and individuals think it’s ok to simply clean roofs with direct pressure washing. WE SAY NO! Direct pressure washing leads to:

  • non-uniform color
  • damaged shingles
  • does not prevent algae, moss or lichen from growing back
  • promoting growth of damaging organisms

Remember, DO NOT ALLOW ANYONE to use high pressure on your roof. Use of high pressure is extremely damaging and voids manufacturers warranties.

Should I Wait To Have My Roof Cleaned?

If you have black streaks (black algae), moss, or lichen growing on your roof. It’s not just an eye sore…


The organisms are feeding off the materials in your shingles and wearing away at the integrity of your shingles and roof. We promise to completely ELIMINATE these problems from your roof and keep your roof healthy for years to come.

How We Clean Your Roof? The Roof Cleaning Process Explained… Step-By-Step

First, our Lead Tech will  introduce himself to you, the customer and then clearly state what we will be doing.

  1. Then we properly prepare the landscaping surrounding your home. We generously water then cover your plants before cleaning the roof.
  2. All gutter drains are bagged to catch any runoff that may occur.
  3. Although it is not required, our preparation assures that your plants and lawn will be unharmed throughout the cleaning process. We take every precaution we can to protect your landscaping around the home.
  4. The tech will then place our ladders up on the gutter line of the roof using a ladder standoff. This helps protect the gutters from being damaged.
  5. Some roofs may have debris such as pine needles, sticks, and loose leaves. Before we begin to apply our soap, we safely sweep and/or blow off the roof when necessary.
  6. After we are sure that your landscaping is protected, we start the TLC Exterior Cleaning Services, Inc. roof cleaning process by gently soaking your roof in our unique cleaning formula from our custom-made spray applicator. What sets TLC Exterior Cleaning Services, Inc.’ formula apart from other roof cleaners products is our formula contains foaming sticking agents that vastly decreases run-off from the spraying process. This helps keep the product off of your lawn, plants, patios, and decks.
  7. We spend the next few hours applying multiple coats of cleaning product to your roof to make 100% certain that we have covered every spot that needs cleaning. Results start to appear right away. You will see the black algae stains starting to disappear immediately and all of the moss and lichen will be turning white in color as it dies. At this point we recommend waiting for the rain and sun to cycle several times for the cleaning to be complete.
  8. You will find that the dead moss and lichen dries in the sun and then washes away in the rain, leaving your roof COMPLETELY CLEAN!

How Long Do I Have To Wait To See Results?

When TLC Exterior Cleaning Services, Inc. cleans your roof, you will start to see results the same day. Most of the black algae will be gone right away. However, the moss, lichen, and problem spots may take a few rain and sun cycles to completely wash off.

Here Is An Example Of A Roof Replacement Cost

A 3,200 square foot roof with an addition on the back. Total cost to replace: $8,400 -$9,600! Wow, that’s expensive! This is an actual estimate that the homeowner received. We can clean a roof for less than 10% of the cost of a new roof! And in this case, it was not needed after visual inspection. There was no damage and no leaks just a mildew infested roof, which is now clean as new.

Reasons Why You Should Have Your Roof Cleaned

Roofs are meant to reflect the sun and keep the attic cool through the use of ridge vents and fans. Black Roofs cost money by absorbing the heat from the sun. This black mold can and will get into your attic and cause a mold problem inside your home, causing other health related problems. Roof cleaning provides:

Avoids Premature Shingle Failure
Allows for Proper Home Maintenance
Energy Savings
Helps the Environment
Increases Home Value

You will also save money on electric bills because the roof can do its job and reflect heat instead of absorbing heat. Retain the life span of the roof with a professional clean.

What your neighbors are saying…
