Do I really need to clean my roof?

Why clean the roof? The roof stains and black streaks aren't hurting anything!

Wrong!! A stained roof costs real money!
Roof Stains cost you real money through:
  • Shortened roof life - Cost $4,000.00
  • Increased energy costs - Hundreds each year
  • Reduced property values - Cost $10,000.00
Those black streaks and roof stains are eating into more than your roof! 

Insurance and Home Owner Associations may also require you to clean your roof.
Increasingly, Insurance companies are requiring roof cleaning to prevent mold infestations, and for several years now HOA have been requiring ugly roofs to be cleaned or replaced.

When it comes to Safety and Health, the stains are a form of mold, and mold that works its way into the home is bad news!
"Sick House syndrome" is real, and can cause you and your family to suffer the ill effects of mold and bacteria.

Do you need to clean your roof? YES.

How to Use a Roof Cleaner

How is Roof Cleaner QSE applied?

Pump Sprayer No special Roof Cleaner Equipment is required. 

You'll just need a pump-up sprayer (commonly called an insecticide sprayer)

Choose a day when the temperature is not freezing (roof shingles need be above freezing (at least 35 degrees) for at least four hours before using roof cleaning chemicals for best results.
For more information: Roof Cleaning and Cold Weather )

Add the contents of a pre-measured EZ-Pouch to water, mix and spray!
Soak a section of roof shingles to the point of saturation
Wait 25 minutes before rinsing
(you can be spraying / rising other sections during this time)
Rinse Away Stains within a few inches with a tight jet spray from a garden hose, or for faster results use a Pressure Washer with a fan tip.

Can I use my Hose End sprayer?

ApplicatorTypically, NO.
Let us explain:
Some customers already have a sprayer that attaches to the end of the hose.
Most hose-end sprayers or "miracle grow" sprayers have the correct WRONG dilution ratio.

A typical hose end sprayer is 1:128 or 1oz of cleaner for every gallon of water.
In other words most Hose End sprayers will add TOO MUCH water, that wastes cleaner and makes it ineffective.

How do I know if it is compatible?
Roof OX and Roof QSE require a 1:10 ratio (12 oz cleaner for every gallon).
Roof Armor (Stain Prevention) requires 1:40 ratio (3oz cleaner for every gallon water).

If your hose end sprayer is not compatible,
Use a pump-up insecticide sprayer
Choose a Cleaner Today Hose End sprayer. (see below)

Help me choose between your Roof Cleaners

All about CHOICE. 

Help me compare Roof QSE and Roof OX.

What is the same with both Roof QSE and Roof OX (used as directed):

  • Safe for roofs, gutters and downspouts
  • Cleans Roof Stains from Algae, leave tannins, mold, mildew
  • Convenient EZ Pouch package (no-measure, concentrated powder)
  • Works in Hard and Soft water
  • NO FILLERS, 100% active cleaners
  • Bio-degradable
  • Cleans without Scrubing
  • Restores roofs appearance
  • NO Chlorine BLEACH, No Acids, No Solvents
  • Will not harm pets, plants, trees, shrubs, garden
What is the Different between Roof QSE and Roof OX:

Roof OX is:
  • The Safest Cleaner for the Environment

  • Better suited for a homeowner who may be uncomfortable handling a professional strength cleaner.

  • Water activated releases oxygen which makes the stain invisible, then continues cleaning to remove the stain.

  • Chemically based composed of Sodium Percarbonate and Phosphate free TSP
    Think OXYCLEAN on steriods, over 85% sodium percarbonate but with our signature detergents and surfactants added.
    An enviromentally friendly version of the Bleach and TSP approach

  • Environmentally safe, Non-toxic, Contains no Hydroxides, Chlorine Bleach or Acids

  • Breaks down into Water, Oxygen and harmless Washing Soda

  • Can be used on painted surfaces.

  • Works 88% of the time on the first pass, sometimes a second pass is needed

  • Draws power from Oxygen, staying active 4 hours once mixed.
    This is fine for a home owner, but contractor prefer QSE because it can be premixed

  • Roof OX Costs a little more, because 1 EZ pouch makes 2 gallons of Cleaner.
    For a homeowner, its like buying a hybrid car, you expect to pay a little more.
    For a Contractor, margins are important, so QSE is the best price choice.

Roof QSE is:
  • Industrial strength formula designed for professionals

  • Works 98% of the time on the first pass

  • Remains Effective in solution for 5 days once mixed, allowing contractors to mix a tank on monday and use it all week

  • Highly concentrated requiring professional safety precautions

  • Fastest cleaner because it can be mixed in advance and pumped from a large tank.

  • most economical cleaner
    1 EZ pouch makes 4 gallons of Cleaner Solution

Can I use Roof Armor to clean a roof?

How much do I need? What is your coverage?

What does Full Coverage mean?

Full Coverage is our term for honest pricing and estimating
Many competitors quote a Range of Square Feet their product will cover. For example "1000 - 1500 sq ft"
What exactly does that mean? It is a variance of 50%.
Assume that 100% strength is the low number, in our example 1500sq ft would be half strength.

Our Approach
The number on the product represents FULL STRENGTH COVERAGE, 100% strength, no ranges, no guessing.
That means our Roof QSE 3000 covers 3000 sq ft, Roof OX 4500 covers 4500 sq ft. (and so on. The numbers on our cleaners are square feet of coverage).
Sure, you could stretch the QSE 3000 to cover more square footage, but then you reduce its strength.

How Much Roof Cleaner do I need?

Our estimates are simple.
1 gallon of cleaner should cover 187.5 sq feet of roof. Roughly 12ft x 16ft.

Yes, we know other companies claim 1 gallon can cover 500 sq ft, we just don't believe it.
Call us conservative, but we actually got on the roof a sprayed 1 gallon of water, and 187.5 sq ft was how far a gallon went.

So let's say you have 1500 sq feet of roof, (see the link below if you aren't sure),
then to clean your roof would require 1500sq feet / 187.5 feet per gallon = 8 gallons of cleaner.

We've saved you the guess work, our Roof Cleaner QSE and OX come in sizes that indicate the square footage they cover 1500, 3000 or 4500. Roof QSE 1500 covers 1500 sq ft, Roof OX 4500 covers 4500 sq ft.

If your roof is 2250, then choose the next higher number for example 1500 is too small, so choose Roof QSE 3000.
Each Product comes in EZ pouches, so if you don't need all the product, you can save the unused pouches for the future, or share them with a neighbor.

For QSE an EZ pouch makes 4 gallons, (750 square feet), For OX an EZ pouch makes 2 gallons (325 square feet).
