This is a Roof Stain Removal job we were hired to clean in Birdsboro, Pa located in Berks County that was probably the best example of the results that can be achieved by using our safe non-pressure soft wash on an asphalt roof. This customer had been so pleased with the results, he signed up on Angies List to leave positive feedback about Landis Roof Cleaning. A few of these pictures are currently being used on our website and print advertising.

Rob,

This was done with a 30% mix ratio. We ran short by a few gallons, so I mixed up another batch and gave a real light second coat over the entire roof with the left over from the second batch. It came out great, so now, on the front of the homes I do I spend a few extra minutes spraying a second light coat using a 2520 nozzle. Most of the time it comes out like this with very little if any light brown residue. This is a good practice in key locations(entrances to a busy neighborhood, open corner lots etc.). When I first started roof cleaning I was a little hesitant in leaving a sign in the front yard with light staining left on the roof. We know it will remove itself with the first rain, but would a potential customer?

The second pic was a week later. The fourth pic was the same day.

Here is a pic that was taken before the second light coat.

Thanks a ton for the reply Barry!  I figured it was either time or a second coat... Do you let it shed off to almost dry or anything like that before second coating?  What surfactant or additives are you using? 

We are new to asphalt roof cleaning.  We've been cleaning heavy moss laden cedar roofs for over 15 years and getting big money for them and sealing with F&P sealer.

Always shyed away from asphalt because heavy Sodium Hydroxide cleaners make them bleed and difficult to pressure wash... plus the damage to shingles.  Doing more & more roofs lately with softwash.  Just trying to perfect the mix and process.

Have you tried AC's Green Wash?  or what do you suggest?

 I appreciate your help bro!

Thanks,

Rob
