Why Lacey roofs go green
Lacey was called Woodland until 1891. The post office turned the name down because Washington already had a Woodland, so the town picked a new one. The trees stayed.
They're the reason. Lacey kept a lot of its Douglas firs, around Long Lake and Hicks Lake most of all, and a roof under a fir never gets a full day of sun. Needles land in the valleys. They hold water against the shingles for days.
The newer neighborhoods aren't safe either. Hawks Prairie has fewer old trees, but every roof there has a north slope. That's where the moss starts.
Leave it and the moss works its way under the shingle edges and lifts them. Then you're paying a roofer.
Why we won't pressure wash it
Asphalt shingles are coated in granules. The granules protect the shingle from sun and rain, and a pressure washer blasts them into your gutters. The roof looks clean for a season and wears out years early.
Soft washing leaves the granules alone. It's slower to show results on thick moss, and we're fine with that.
What happens on the day
- 1
Inspection
We walk the roof and find the problem areas before anything gets sprayed.
- 2
Plants rinsed
Shrubs and beds near the house get a rinse before we start, and another when we finish.
- 3
Treatment
A cleaning solution goes on the shingles and kills moss and algae at the root.
- 4
Gentle rinse
Low pressure takes the debris off. The roof stays intact.
When to book it
- Late spring to early fall
- The easy window. The roof is dry, the days are long and the solution gets its full time on the shingles.
- Fall
- Rain is back and fir needles pile up in the roof valleys. Good time to clear debris and look at the gutters.
- Winter
- Peak growing season for moss. We still clean on dry days above freezing.
One thing people don't expect. In August moss dries out, turns brown and looks dead. It isn't. The first good rain in fall and it's green again, a little bigger than last year.
Don't wait for summer if
- The moss is thick enough to lift the edges of the shingles
- Clumps of it keep landing in your gutters or on the driveway
- You're planning to sell
- A home inspection is coming
After we leave
Thin growth is gone the same day. Heavy moss is dead but can keep letting go of the shingles for a while, and the rain carries it off. Expect 12 to 24 months before you see green again. Under big firs, plan on the short end of that.
Roofs we clean
Asphalt shingles mostly, because that's most of Lacey. Tile, metal and slate too. Soft washing is safe on all four.
While we're in Lacey
What comes off a roof ends up in the gutters, so they're the obvious next job. Here's the rest.
- House Washing
Soft wash for the siding under that roof.
- Gutter Cleaning
Debris out, downspouts flushed. Worth doing after any roof cleaning.
- Pressure Washing
Concrete, brick and stone.
- Patio and Driveway Cleaning
Driveways, patios and walkways that went dark over winter.
- Deck and Fence
Wood and composite, cleaned at the right pressure.
- Window Cleaning
Inside and out, all year.
Roof cleaning in Lacey: questions
Every two to three years for most roofs. Under big firs, sooner. If you can see green from the street, it's time.
One to three hours for a typical house. Heavy moss can keep releasing from the shingles for a while after we treat it. That's normal.
Yes. It's safe for asphalt shingles, tile, metal and slate. We clean at low pressure, so shingles, flashing and granules stay put.
We rinse nearby plants before and after the job to keep them safe.
Clear loose items off the roof if there are any, and make sure we can walk the perimeter of the house. Tell us about any spots you're worried about.
Typically 12 to 24 months before moss shows again. It depends on tree cover and weather. Some Lacey homes need a visit every year and others go a couple of years.
No. As long as we can get to the roof, we can do the job without you there.
Yes, on dry days above freezing. Ice on a roof is where we draw the line.
