Why Customers Choose Aloha for Roof Surface Cleaning:

Roof cleaning for Seattle and Eastside homes — a careful approach that respects what the shingles and surrounding landscaping can handle.

Careful Method for Exposed Roof Surfaces

Roofs respond poorly to high-pressure water — it can dislodge surface material, lift edges, and force water under the underlayment. We use a careful, low-pressure method designed for residential roof surfaces, with a controlled rinse afterwards.

The roof comes out cleaner with a method chosen for the surface, instead of being blasted with high-pressure water.

Moss, Lichen & Dark Staining Removal

Seattle’s moisture and tree cover give roofs a tough environment. Moss patches, lichen spots, and dark vertical streaks are the most common things we remove, and they’re not just cosmetic — they hold moisture against the roof surface.

A clean roof looks better from the curb and from above, and the surface dries more evenly between rains.

Rinse Control Around Landscaping & Exterior Areas

Roof cleaning rinse can run straight into garden beds, lawns, and walkways below. Before we start, we pre-rinse plants, route runoff away from sensitive areas, and follow up with a clean-water rinse on the landscaping.

Your garden looks the same when we’re done — and your roof looks much better.

We bought a fixer-upper in West Seattle and the previous owners clearly hadn't cleaned the outside in years. Siding, windows, walkways, the whole thing looked tired.

Aloha bundled soft wash, exterior windows and pressure washing into one package and the price was way more reasonable than I expected. The transformation was huge. Two neighbors literally walked over to ask who did the work.

Family-run business that actually cares. So rare these days.

Had our solar panels cleaned for the first time in three years. Visible difference in our power output the next sunny day, my husband actually pulled up the app and showed me.

Proper soft-bristle equipment, pure water, no streaks or scratches. They also noticed one mounting bracket needed tightening, which we never would have caught ourselves.

Great value, great people. Booked them again for the fall already.

I run a small retail shop on the Eastside and the front glass and sidewalk take a beating in the winter. Aloha now comes by every six weeks. Windows cleaned, sidewalk pressure washed, entry door spotless.

They come before we open, never disturb a single customer, and the invoices are clean and easy to track. Same crew every time, which is huge for me.

If you run a business in Seattle or Bellevue and need a reliable exterior partner, these are your people.

I manage a small office building in downtown Bellevue and we've gone through three different window cleaning companies in two years. Aloha is the first one I actually plan to keep.

Quick, reliable, communicate clearly, and the work is consistent every visit. Tenants have noticed and commented on how much brighter the lobby looks. Already moved them onto a quarterly contract.

Quick response, came out the same week, did a great job on the windows before our daughter's wedding. Couldn't be happier. Thank you guys!

FAQ

Roof Surface Cleaning

What does roof surface cleaning include?

Roof surface cleaning focuses on visible roof areas affected by moss, lichen, dark staining, debris, and seasonal buildup. The goal is to improve appearance and cleanliness using a careful method suited to the roof surface.

Is moss on a Seattle roof actually a problem?

Moss is common in the Pacific Northwest because of rain, shade, and long damp seasons. Over time, heavy moss can make a roof look neglected and may hold moisture on the surface. Cleaning helps improve appearance and supports regular exterior maintenance.

How often should roof surface cleaning be done in the Pacific Northwest?

The timing depends on shade, nearby trees, moisture, roof material, and visible buildup. Some Seattle and Eastside homes may need roof surface cleaning every one to two years, while others may need it less often.

How long do results last after roof cleaning in the Pacific Northwest?

Results depend on the roof’s exposure to shade, moisture, trees, and seasonal weather. Cleaning removes visible buildup, but moss and organic growth can return over time. Regular maintenance is the best way to keep roof surfaces looking cared for.

What precautions do you take for plants and runoff during roof cleaning?

We review the areas below the roofline before starting and work carefully around landscaping, walkways, and exterior surfaces. Access, rinse control, and nearby sensitive areas are considered as part of the cleaning plan.

Do you use high pressure on roof surfaces?

High pressure is not appropriate for many roof materials. We choose the method based on roof surface, condition, access, and safety. The goal is to clean carefully without using unnecessary force.

Seattle’s wet climate and tree cover create perfect conditions for moss, dark streaks, and organic buildup on roofs. Left untreated, this affects both how the home looks and how the roof handles moisture over time.

Our roof surface cleaning service uses careful, low-pressure methods designed for shingles and exposed roof areas. The goal is a cleaner, more even roof surface and a property that looks well maintained — without aggressive cleaning that could harm the materials.
