Features And Benefits Of Roof Cleaning
Moss & Algae Removal
In Oregon, moss and algae can start growing on just about any surface, especially your roof. If left unchecked, moss and other organic material can cause real damage to your shingles. Prevent moss roots from causing shingles to lift while avoiding shingle decomposition caused by algae and bacteria. Elongate the life of your roof with a roof cleaning and moss removal service today.
Gutter Cleaning
Clearing downspouts and gutters will prevent the backflow of water onto your roof, which can overflow onto your home's siding and foundation. Roof drain cleaning service will effectively safeguard against roof leaks, soil erosion, and siding damage. Protect your investment with a gutter cleaning from National Roofing.
Increase Curb Appeal
Real estate professionals agree that curb appeal is a major factor when selling a home. Having a show-worthy roof gives potential home buyers confidence in the durability of your home. Elevate your home's curb appeal with a roof cleaning by National Roofing.
Before-and-After Photos
Most homeowners can't see the top of their roof, so how do they know that the moss was removed, or that the gutters were cleared? National Roofing solves this problem by providing before-and-after photos with every roof cleaning service. We are always proud to show homeowners our work!

All Roof Types
We Clean Every Type Of Roof
Oregon's wet climate promotes moss and algae growth on every type of roofing material. Our technicians are trained and equipped to safely clean all residential roof types without causing damage to the roofing material or voiding manufacturer warranties.
Composition / Asphalt Shingles
Soft wash treatment removes moss and algae without damaging granules.
Metal Roofing
Safe cleaning methods that won't scratch or damage metal panels or coatings.
Flat / Low-Slope Roofs
Gentle cleaning for TPO and PVC membranes that preserves the waterproof surface.
Cedar & Wood Shake
Specialized treatment that cleans without causing wood damage or splitting.
Why Moss Is A Serious Problem In Oregon
Oregon's wet climate makes moss growth almost inevitable on residential roofs. Left untreated, moss can cause significant and costly damage.
Moisture Retention
Moss holds moisture against your shingles, accelerating deterioration and reducing the lifespan of your roof by years.
Shingle Lifting
Moss roots grow under shingles, lifting them and creating gaps where water can penetrate and cause leaks.
Algae & Bacteria
Algae and bacteria feed on shingle granules, breaking down the protective coating that shields your roof from UV and weather.
Gutter Blockage
Moss debris washes into gutters and downspouts, causing blockages that lead to water overflow and foundation damage.
Curb Appeal
A moss-covered roof significantly reduces your home's curb appeal and can lower its perceived value to buyers.
Costly Repairs
Untreated moss can lead to premature roof replacement — a $10,000–$25,000 expense that regular cleaning can prevent.

"I get annual roof cleanings since National Roofing installed my new roof and gutters several years ago. As usual, the technician texted 30 minutes before arrival so we had a heads up. Roof and gutters were cleaned for a reasonable price. Cleaned up afterward and left everything tidy."
