Our Method

Dear Homeowner,

Unfortunately, this information is VERY necessary. For years we have been professionally servicing roofs and trying to help homeowners clean/repair roofs damaged by weather and often worse…roof cleaning “services”. When we inspect roofs we continue to see damage that was completely avoidable. The sad fact is that much of the damage is due to do-it-yourself owners and “professional” cleaners who unwittingly caused this damage to your home by using methods and equipment that removes protective barriers and strips the life out of your roof while spreading treatments that are either damaging to your roof, flashing's, gutters, fasteners or worse, leave your roofing system with no protection against roof-damaging decomposing moss and bacteria. In some cases we could have saved the home owners hundreds, but in many cases we could have saved them thousands of dollars. We can’t tell you how many times we've heard homeowners tell us, “I wish I’d talked to you sooner!”

Please take a few minutes to continue reading, and save yourself trouble, and money!

There are 3 critical factors you need to know when your roof is cleaned, maintained or repaired:

1. How to identify which equipment, method, and treatments your contractor should use on your roof.
2. How to choose a contractor that understands your roof system and how to clean or repair your roof without causing damage.
3. How to be guaranteed your roofing system was serviced properly and with a Warranty you can actually count on.

The Breakdown: 3 Typical Methods and why they don't work

1. Damaging High Pressure (Water) Washing: High-pressure, pressure-washing (2500 to 6000 PSI of raw power) blast away debris, but can remove actual roof material the cleaning process is intended to improve.
   • Beware of "Gentle" pressure washing claims! Some cleaners call their high pressure water systems "Gentle Cleaning". It sounds good, but can blow holes in roofs and flashing's. This causes secondary damage greater than the moss or original problem the service was intended to correct.
2. "High Pressure" Air Cleaning: High pressure air was originally used to blow loose debris off shake roofs too brittle or damaged to be cleaned by pressure washing. It works well for moss removal but must be used properly by trained technicians to prevent damage to your roof and also must be followed by an active moss treatment to prevent the moss from growing back. Most contractors only follow up with very ineffective long-term treatments that leave your roof discolored for months and once the rain has rinsed the treatment away, so does the moss prevention. That is why it has to be done repeatedly.  
3. "Wire Brush & Scrape" Cleaning: This process typically uses aggressive wire brushes to scrape moss off the surface then coarse brooms to sweep away the dislodged moss. Again most contractors apply ineffective passive treatments after the cleaning. The problem for composition scraping embedded moss can de-laminate the composition from the fiberglass backing and cause roof damage and failure. Composition has definition (cracks and crevices) that can be missed by a brush. Moss spores reproduce by the billions. That is why your roof can be cleaned with this method and moss returns within a year. Bacteria and fungus spores re-grow under your shingles where the brushes can't reach. The only way this method can be effective is when it is combined with an active treatment that eliminates the spores down to their roots and prevents future growth. 

The greatest danger with each of these methods is using ineffective treatments or no treatment at all

Passive Treatments

Passive treatments like zinc powder or liquids don't eliminate the fungus or the bacteria that caused the moss and algae in the first place. Once it is washed off from the rain, its ability to halt moss growth is gone.

Cleaning without Treatment

Cleaning without treatment guarantees you'll have moss back almost immediately. Removing moss and algae by simply removing what you can visibly see is like snapping weeds off at the surface. Spores and bacteria reproduce in the millions and travel by rain, wind and growth.
