Roof Cleaning and Moss Removal in Grants Pass, OR
River town humidity and heavy canopy make this moss country. We use a low pressure soft wash that removes moss, lichen, and black algae streaking without damaging your shingles, and every roof cleaning is backed by our 18 month moss free warranty.
Roof cleaning built for Grants Pass conditions
Grants Pass gets noticeably more rain than Medford does, and it sits right on the Rogue River. That combination of higher rainfall and constant river humidity makes it some of the worst moss territory in Southern Oregon. Roofs here often need cleaning every two years, and homes tucked into the trees sometimes sooner.
We work throughout Grants Pass and out toward Merlin, Hugo, and Redwood. The properties along the river and up in the shaded draws are the ones we see with the thickest growth, often a full mat of moss lifting shingles along the ridge and in the valleys.
Cleaning a roof before that mat gets established is one of the cheapest things a homeowner here can do. Once moss has lifted enough shingles for water to get underneath, you are looking at deck repairs instead of a wash.
Book a Roof AssessmentWhy Grants Pass roofs take the worst of it
Higher annual rainfall
Josephine County sees more rain than the Medford side of the valley, and the wet season runs longer, which gives growth more time to establish.
River humidity
Properties near the Rogue and its tributaries hold moisture in the air year round, so roofs never fully dry out the way they do further inland.
Dense forest cover
Fir and pine over many Grants Pass lots means constant needle drop and very little direct sun on the north facing slopes.
Older roofs across the city
A lot of housing stock here is on its second or third decade of shingle, and aged shingles hold moss far more readily than new ones.

How we clean a roof in Grants Pass
The same four steps on every job, whether it is a single story home in town or a steep roof up in the trees.
Inspect
We walk the roof and check pitch, shingle condition, flashing, and problem slopes, then tell you honestly whether cleaning is the right call.
Protect
Landscaping, gutters, downspouts, and any sensitive surfaces get covered and pre rinsed before a drop of solution goes down.
Soft wash
A low pressure treatment kills moss, lichen, and algae at the root instead of scraping the surface and taking granules with it.
Clear and rinse
Loose growth and debris are removed, valleys and gutters cleared, and the property rinsed down and left clean.

Roof cleaning questions from Grants Pass homeowners
How much does roof cleaning cost in Grants Pass, OR?
Roof cleaning is priced by roof size, pitch, and how heavy the growth is, so a small single story home costs considerably less than a steep two story with years of buildup. Every quote is free, firm, and carries no obligation to book.
Will pressure washing damage my roof?
High pressure absolutely can, which is why we never use it on shingles. Blasting a roof strips the protective granules and can void your manufacturer warranty. We use a low pressure soft wash that kills growth at the root and rinses gently.
How often should a roof be cleaned in Grants Pass?
Most homes here do well on a two to four year cycle. Roofs under heavy tree cover or on shaded north facing slopes usually need attention closer to every two years.
What does the 18 month moss free warranty cover?
If moss regrows in any area we treated within 18 months of the service, we come back and re treat that area at no additional cost. It applies to every roof cleaning we perform, with no separate signup and no extra fee.
Are your cleaning products safe for plants and pets?
Yes. We pre rinse and cover landscaping before we start, apply treatments at safe dilution, and rinse everything down afterward. Pets can be back outside once the area is rinsed and dry.
Do you charge extra to travel to Grants Pass?
No. Grants Pass is a regular part of our route and there is no travel surcharge. We schedule Grants Pass jobs together where we can, so if a neighbor wants their roof done at the same time it is worth mentioning when you call.
