Roof Cleaning in The Woodlands and The Woodlands area

Our roof cleaning uses a soft wash method: low pressure and a cleaning solution that kills the algae, mildew and lichen staining your roof. We never put high pressure on shingles. Sebastian's Washing Services is insured, based in Spring, and serves homes across The Woodlands area.

What roof cleaning covers and how we do it

Roof cleaning removes the dark streaks, green moss, lichen spots and mildew that build up on a roof over time. We treat the whole roof surface, not only the worst patches, so it dries to an even color. Gutter faces and nearby siding get rinsed as part of the job.

Roofs are always soft washed. That means low pressure and a cleaning solution that kills the growth. High pressure can strip granules and push water where it should not go, so we never use it on a roof. Heavy lichen may not rinse away the same day. It is dead after treatment and will loosen and wash off with rain over the next few weeks.

  • Black algae streaks
  • Moss and lichen
  • Mildew and organic staining
  • Gutter faces and nearby siding rinsed

What to expect on the day and when to book

We start by protecting your yard, then apply the solution and rinse. You do not need to be home if there is an outdoor faucet we can use. Keep pets inside and close windows near the roofline. Most homeowners see the roof turn lighter while we work, with the full result showing after it dries.

Book a roof cleaning when you first notice streaks or green spots, not years later. Growth spreads fastest on shaded, damp sections of a roof, and early treatment is easier on the shingles. Many homeowners pair it with house washing so the roof and siding look clean together.

Why roof cleaning from Sebastian's Washing

  1. Streaks gone, not just faded

    The cleaning solution kills the algae that causes dark streaks, so the stain lifts out instead of being blasted at the surface.

  2. No high pressure on your roof

    Soft washing uses low pressure, so we clean the roof without forcing water under shingles or knocking loose granules.

  3. Moss and lichen treated at the root

    Growth is killed where it sits. What remains loosens and rinses away over the following weeks.

  4. Plants and property protected

    We pre-wet, cover and rinse landscaping around the house before, during and after the wash.

How it works

  1. 1

    Look over the roof

    We walk the property, note the type of staining and growth, and check gutters, downspouts and the plants below.

  2. 2

    Protect the yard

    We pre-wet shrubs, flower beds and grass near the drip line and cover sensitive plants where needed.

  3. 3

    Apply the soft wash solution

    We apply the cleaning solution at low pressure across the roof and give it time to break down algae, mildew and lichen.

  4. 4

    Rinse and final check

    We rinse the roof edges, gutters, siding and landscaping, then walk the property again to make sure everything is clean.

“We are extremely pleased with our service! The communication from Sebastian is excellent. He is very professional, and also very friendly. I felt he went above and beyond. We had our huge driveway cleaned plus both the front and back porch, the siding + garages, and beams of our house cleaned. Algae, mold, pollen, water staining - all gone. I have major allergies and feel like I can enjoy my porches again. Windows and screens was a small add on and I’m glad we included, you can’t even see the screens anymore! He spent all day here but no detail was overlooked and it looks as good as the day we moved in! Worth every penny and then some. Would totally recommend.”

“Courteous young man. His company is insured also. Did an amazing job on my patio. Fair price and He also helped me with my hose that was stuck on the outdoor tap in the back. I will use him again. The patio is still a bit wet in picture and he dealt with new and old cement. 5 stars ⭐️⭐️⭐️⭐️⭐️”

Roof Cleaning questions

Will roof cleaning damage my shingles?

Not with a soft wash. We use low pressure and a cleaning solution, never a high-pressure wand on your roof. The solution does the work, so shingles are not scoured.

What are the black streaks on my roof?

Those streaks are usually algae growing on the shingles. It spreads slowly and holds moisture. A soft wash kills it so the streaks can be removed.

Do I need to be home during the cleaning?

Usually not. If we have access to an outdoor water spigot, we can do the job while you are at work. We will let you know when we are done.

Is the cleaning solution safe for my plants?

We pre-wet and protect your landscaping before we start and rinse it well afterward. That keeps the solution diluted and away from roots and leaves.

How much does roof cleaning cost?

Every roof is different in size, pitch and how much growth is on it, so we give free quotes after looking at your home. Call or email and we will set a time.
