Spokane Roof Cleaning

The environmentally friendly Roof Shampoo® products are proprietary and only available to authorized Roof Shampoo® Contractors. 

NEVER!  High pressure powerwashing can be very damaging to the shingles. Plus, it’s simply not an effective way to remove algae stains from roofs. All of our roof cleaning equipment is specially calibrated at a very low pressure to ensure a safe and effective washing away of the stains that are released by the Roof Shampoo® products.

Be very, very careful here. Many homeowners and contractors alike have tried to use bleach or pool chlorine to remove the dark roof staining caused by algae. The results can be disastrous. First of all bleach and pool chlorine are dangerous chemicals that can damage vegetation, dry out your shingles, and corrode roof fixtures such as flashing, underlayments, valleys, and boots. Any results that the homeowner sees are often just temporary and the staining is back within a few short months because the bleach merely addresses the surface algae and not the root system underneath the granules. 

These products can cause many problems. Many of them are toxic to the vegetation surrounding your home. Plus, they are largely ineffective in the long term, as well as the short term as far as roof stain removal goes. Also, whenever homeowners climb up on their roof, they put themselves at risk of slipping and falling. Roof cleaning is serious business and it’s always best to rely on the professionals.

Roof Rejuvenate is made with 92% bio based natural food grade oils. It is safe in small quantities, easily washed off with water, but like water in a flood it’s not 100% safe but is safe around pets, plants and people.

Typically shingles that are ten years old start to show signs of aging, granular loss and could use rejuvenation before they start to curl up and become brittle.
