Squatch Roofing applied a Roof Maxx treatment and a SasWash to a laminate shingle roof in Bothell, WA 98021 on July 29, 2026. The house sits under tall trees, and the July 20 inspection found conifer needles piled against the two skylights. On the low roof sections, dark and green growth had spread across the shingles along the eaves. The same visit included a blow-off of the debris and sealant on exposed nails, per the job’s line items.

What Squatch Found on the Inspection
The inspection on July 20, 2026 spent most of its time in the attic, then went up on the roof.
- Attic: the roof deck is spaced board sheathing, painted white on the underside, with roofing nail tips coming through between the boards. At the gable vent, the paint on the louvers was peeling.
- Skylights: two skylights side by side on the main roof, with conifer needles piled against the curbs.
- Chimney: a brick chimney with flaking brick faces and debris caught in the flashing where it meets the roof.
- Shingles: gray laminate shingles on the main roof, photographed up close for the surface.
The chimney brick and the gable vent paint were documented and left out of scope. Neither is on this job’s invoice.


Why We Recommended Roof Maxx With a SasWash
The problems the photos record on this roof are on the surface: tree debris at the skylights and growth on the low roof sections. The photo set does not record missing or broken shingles on the main roof. That made it a candidate for maintenance rather than replacement, so Squatch quoted four pieces of work for one visit: blow the debris off, SasWash the roof for the growth, seal exposed nails, and apply Roof Maxx to the shingles. The homeowner approved all four.
Roof Maxx describes its product as a plant-based treatment that soaks into asphalt shingles. On this job it went on the same day as the wash.
How the Project Was Completed
July 29: the crew set ladders at the low roofs and the main roof. The crew first photographed every slope, including the low roof sections where dark and green growth ran along the eaves and up the shingles. The treatment photos that follow show the main roof slopes coated and reading light gray, around the skylights, box vents, and the black pipe vent near the ridge. The last set shows the low roof sections with an even, dark surface and the growth gone.
The photo log does not separate the wash, the blow-off, and the nail sealant into their own steps, so this post does not describe them one by one. They are on the invoice.


The Finished Result
By the end of the visit the main roof was coated with Roof Maxx and the low roof sections were clear of the growth photographed at the start of the visit. There is no dry, days-later photo on file, so the after image shows the coat while it was still fresh. The treatment carries the Roof Maxx 5-year transferable warranty.
What This Roof Maxx Treatment Cost
Project investment range: $3,300 to $5,100. This range reflects the scope of this completed project and is not a current quote. It is anchored on the final invoice total, which includes Washington sales tax.
The price covers four line items in one visit: the SasWash, the Roof Maxx treatment, the debris blow-off, and nail sealant. A roof with less tree debris or no growth to wash would need fewer of them.
What Homeowners With Similar Roofs Should Know
Low roofs collect growth first. On this house the low roof sections along the walls carried most of the visible growth, more than the main roof. Check the lower roofs, not just the slopes you see from the street.
Skylights hold debris. Under tall conifers, needles stacked up against both skylight curbs. A blow-off before any treatment clears them.
An inspection finds more than the roof needs. The chimney brick and the gable vent paint were photographed and reported, but were not part of this job. You decide what to act on.
Related questions
How much did this Roof Maxx treatment in Bothell cost?
The project investment range was $3,300 to $5,100 for a Roof Maxx treatment, a SasWash, a debris blow-off, and nail sealant in one visit. The range reflects this project’s scope and is not a current quote.
What did the inspection find?
Conifer needles piled against the two skylights, flaking brick faces on the chimney, and peeling paint on the gable vent louvers seen from the attic. The chimney and the gable vent were out of scope for this job.
Why was Roof Maxx recommended instead of a new roof?
The problems the photos record were on the surface, debris and growth, and the photo set does not record missing or broken shingles on the main roof. That pointed to cleaning and treating the roof rather than replacing it.
Why does the roof look white in the after photo?
Freshly applied Roof Maxx reads light on the shingles until it soaks in. The after photo was taken the same day, on July 29, while the coat was still fresh.
How long did the job take?
One visit on July 29, 2026, nine days after the July 20 inspection.
