Non-Pressure Roof Cleaning

Why Your Roof Is Turning Black

If your roof appears to be dirty, it’s more than likely roof algae. Roof algae, also known as Gloeocapsa Magma, is a type of algae that thrives in humid and warm climates and usually appears first on the North slope of the roof where shade is prevalent and moisture tends to accumulate. The result is usually a black streaked roof. Roof algae, once attached to a roof, feeds on the dead organic matter used in the manufacturing process. This causes the roof to deteriorate prematurely and diminishes the roof’s abilities to reflect heat rays. If not treated, the roof algae will reduce the life of your roof, diminish your home’s curb appeal and increase your home cooling expenses.

What High Power Pressure Washing Will Do To Your Roof (If You Like Money, Don’t Do This)

If you yourself, or allow another to Pressure Wash your roof, know that you are greatly reducing the life span of perhaps the most expensive portion of your home’s value.  This “money saving” style of cleaning takes roughly 5-10 times longer than a Chemical Cleaning which equates to 5-10 times more walking.   This almost certainly ends in many tiles being cracked and needing repair or replacement.

A good roof design has a decent pitch with roof tiles overlapping starting from the bottom edge all the way up to the top.  This allows water to flow from the top of the roof down without any chance of intrusion into the underlayment and plywood.  Pressure Washing the edges of joining tiles as well as the faces of the tiles will undoubtedly introduce water into the underlayment section of your roof.  There is just too much force and water volume to avoid it.  As an added bonus, when the roof starts leaking and you call your roofer/manufacturer to honor the warranty, they will happily direct you to the clause which states “High Power Pressure Washing Voids This Warranty”.

Effectivenessless In Cleaning – High Pressure 

Pressure Washing your roof will remove surface algae build up and assuming the cleaning did not completely destroy your roof’s ability to preform it should look relatively clean from the ground when all is done.  This should last a good 6-8 months and then you’ll need someone to come back to re-terrorize the roof.  Roof tiles are porous and Pressure Washing them only scrapes away what you can see on the surface.

The Answer – Non-Pressure Roof Cleaning 

Our Safe Low-Pressure Chemical Cleaning application will clean your roof quickly, safely and effectively. This type of cleaning will clean better and last a whole lot longer.  We use cleaning agents which will be gently sprayed onto your tile or shingle roof while protecting vulnerable areas like grass, flowers and bushes.   The cleaner soaks into the substrate and completely kills all living organisms.  Some companies offering similar services would end the job here and be on their way..not us.  Eventually, it will rain and that chemical will re-activate and end up pouring onto your grass and plants.  No one will be there to keep those areas covered and protected and they will likely sustain some degree of damage.  We will completely rinse the roof area down with fresh water while keeping your plants protected as in the chemical application.

  • Entire roof is chemically cleaned with a low-pressure, algae-killing application
  • Roof edges and faces of gutters are cleaned to removed green and black algae
  • All plants, shrubbery and grass beneath the roof cleaning are fully covered and watered to keep your landscaping protected.
  • After the chemical has worked in and fully eliminated the algae, the entire roof is rinsed down with fresh water to prevent plant damage during next rain.
