Asphalt Shingle
Asphalt shingle is the roof we see most on homes in this area, and it leads our work. On shingle, the algaecide and soap mix goes on from the ladder and does its work right where it sits.
Roof Cleaning in Essex and Middlesex County, MA
Soft Washing Moss, Algae, and Lichen
Off Essex and Middlesex Roofs
Moss, algae, and lichen can grow on roofs throughout Essex and Middlesex Counties, leaving shingles with green or black staining. Sean’s Property Services soft washes roofs with a mix of algaecide and soap to treat the organic growth at its source. If you’ve noticed staining or growth on your roof, call us at 978-995-3110 to schedule an estimate.
Roof Types We Soft Wash,
From Asphalt Shingle to Cedar
Every roof below gets the same soft wash, never pressure. The method stays gentle on the surface while the treatment does the work.
Slate
Slate gets the same soft wash and the same care, with no pressure on the surface. You still see it on some of the older Victorians around here.
Metal
Metal roofs are soft washed the same way. The treatment kills the growth without anything abrasive touching the finish.
Tile
Tile is cleaned with the same soft wash approach, never a pressure washer.
Cedar
Cedar is a wood roof, and it takes a different process than the others. If you have a cedar roof, we will walk through it with you at the estimate.
We Never Pressure Wash
a Roof or Rinse Your Shingles
We never pressure wash a roof. Our treatment kills the moss and algae at the root; the dead growth turns white and the rain takes it off over the following weeks. That's the safe way. Rinsing a roof strips the granules off your shingles. We have seen what the other approach does. One roof we looked at had been pressure washed a couple of years earlier. By the time we got there, the moss was already back and the shingles were ruined. The whole roof was due for replacement, which costs far more than any cleaning.
Why Homeowners Choose Us
for Straight Talk on Roof Cleaning
Homeowners call us back because we tell them the truth about their roof, even when the truth costs us the job.
Straight Answers, Even When Your Roof Doesn't Need Cleaning
We don't mince words. You'll get exactly what we tell you you're going to get. And if we can't do something, or your roof doesn't actually need cleaning, we'll tell you that too. We would rather lose a job than sell you one you don't need.
Property Protection Comes First
Property protection is the number one priority on every job, and on a roof it matters more than most. The treatment kills whatever organic material it touches, so we protect what should stay untouched. We cover exposed outlets and painted doors before we start, and we keep a close watch on your landscaping the whole time. You should never pay for a clean roof with a damaged home.

How Roof Cleaning Works,
From Address Lookup to Invoice
A Free Estimate From Your Address
Call, text, or fill out the form, and our office assistant usually picks up. For most roofs we look up your property and price the job from the square footage, with a couple of photos if we need them. Complex roofs get an in-person look. The estimate is free either way.
Accepting Your Estimate and Getting an Arrival Window
Accept your estimate online and we schedule you right away. You get a text and email with your date and a one-hour arrival window, a reminder the day before, and another the day of. When the crew is on the way, you get a message with an ETA, and they knock when they arrive.
Checking Where the Runoff Will Go
The first job on site is working out where the runoff will land, whether that is a gutter, a bush, or the lawn. Because the treatment kills any organic material it reaches, we redirect the water or cover the plants before anything goes on the roof.
Brushing Off Heavy Moss and Lichen
Heavy moss and lichen get brushed off gently with a firm-bristle brush. We clear the loosened debris out of the gutters or rake it up so it is gone before the treatment goes down.
Soft Washing From the Ladder
We apply the algaecide and soap mix to the shingles from ladders, and it kills the growth down to the root. The roof is left to weather rather than rinsed. Two technicians work the job, one applying and one keeping your plants and shrubs rinsed with plain water the entire time.
Wrap-Up and Invoice
The crew marks the job finished and lets you know, then rolls the hoses and packs up. Your invoice follows. If anything about the work isn't right, we want to hear about it, and we will make it right.
What Roof Cleaning Costs, Priced
by Your Roof's Square Footage
Roof cleaning is priced from the square footage of your roof, so the exact figure comes with your free estimate.
$800–$2,000
$800–$2,000 for most roofs. That range covers most homes. The low end is for smaller, simpler roofs. The high end is for large roofs with dormers, steep pitches, or heavy growth. Cedar roofs are priced differently because they are wood.
Bundle & Save
Three-service bundle. Roof cleaning counts toward a bundle, so you get 10% off when you book three or more services. It pairs naturally with a house wash, gutter cleaning, or exterior windows.
Our Make-It-Right Promise
on Every Roof Cleaning
We stand by our work. If something isn't right because of something we did, we'll come back and make it right, no runaround. Call us, send a photo, and we will come look if we need to. We will figure out whether the issue is our work or a condition that was already there, and we tell you straight either way. Normal wear over the years is a different thing, and we are honest about that too.
Frequently Asked Questions
How long does a roof cleaning take?
Most roofs take about four hours. Two technicians are on site the whole time, one applying the treatment and one protecting your landscaping.
Will you clean a roof that has missing shingles?
No. We don't clean a roof that is missing shingles, because the surface needs to be sound before any treatment goes on it. Shingle repair isn't something we offer, so that work would need to come first.
