Roof Softwash & House Washing in the Greater Seattle Area

High Point Gutter softwashing a home exterior

In the Pacific Northwest, your roof is fighting moss, algae, and mildew every season. Left alone, that growth holds moisture, lifts shingles, and shortens the life of your roof. Softwashing clears it the right way. High Point Gutter uses a gentle, low-pressure wash that lifts dirt and kills growth at the root, on roofs and siding alike, across Snohomish County, King County, and the greater Seattle area. Your home comes out clean without the damage a pressure washer can cause.

What Is Softwashing?

Softwashing uses low pressure and a cleaning solution to do the work, instead of blasting the surface with force. The solution breaks down moss, algae, and mildew at the root, then rinses away clean. It is the method roofing manufacturers recommend, and it is safe for shingles, siding, and the landscaping around your home.

Why Low Pressure Beats Pressure Washing

High pressure can strip the protective granules off your shingles, force water under siding, and void some roofing warranties. On a Pacific Northwest roof, that does more harm than good.

Softwashing gets the same clean result without the risk. It is gentler on your home and the results last longer because the growth is killed, not just knocked loose.
