Alliance uses professional cleaning solution and tools.

Siding Wash:

We either pressure wash the siding, or scrub and rinse with a hose and water depending on what kind of siding you have.

Alliance knows that moss in the Pacific Northwest can take over your roof quickly, and we know just how to treat it for you. Our treatments will not only rid your roof of moss, our maintenance program can keep it from coming back.

Maintenance Recommendations:

Once we've done an initial roof moss treatment, we recommend that you call us every 1 to 2 years for a roof inspection.

We pressure wash wood or concrete decks, walkways and driveways. Pressure washing is great for removing mold, mildew and green slime.
