ROOF CLEANING
TREATING

Safe & Effective

     Roof Cleaning-Treating done properly is a Safe and effective way to extend the life of your roof while helping keeping your house looking in top shape.  We recommend the safest gentlest option to clean-treat your roof based condition of your roof.   Below we give a description of some of the options for different kinds of roofs.

Asphalt, Composite,
Fiberglass,  or 3 Tab

Tile or Terra Cotta

Wood Shake Roof

Because of the fragile nature of the small limestone rocks coating this kind of roof we don't recommend pressure washing, instead we do a light scrape to pop off larger chunks of moss, then blow off the roof, clean the gutters, and apply a Zinc Sulfate treatment to kill moss.  Then each year as you clean your gutters  another zinc treatment can be applied if needed to keep the growth from coming back.  Some houses need to be treated up to 2 times a year (until moss falls off then less often) and some can go a few years without needing to be retreated.  The Average house cost between $150-250 but can be more or less based on your specific situation, with  follow ups less and if done with another service very reasonable.

Our First and favorite choice is to blow the roof & gutters, and apply clear crystalizing treatment that comes with a  5 year guarantee  against regrowth as long as the roof is kept clear of debree, and completely coats the whole roof.  The treatment crystallizes all growth on the roof then in 3-6 months of weather sloffs it all off and leaves a beautiful silver shake roof with no wood loss from pressure washing.  It is also a flame retardant and pest retardant.  Simple Joys doesn't actually service this type of roof but we can refer you to the originators of this process to service your roof, costing between $400-600 for the average roof.  We have worked with them for 9 years with good results.
The last option for those who like a cedar tone roof is to pressure wash, then if wanted apply Shakelast a cedar toned copper napthenate penetrating protectant, costing between $500-750 for the average roof.

Tile & Terra Cotta as the shakes above can either be air blown including gutters and a Pyroshield treatment applied or pressure washed.  The Pyroshield carries a 3 year warranty against regrowth on tile as long as the roof is kept free a debree.  the pricing is also the same as shake at 27-40 cents a square foot based on pitch and difficulty of roof.
