Identify the Problem Areas

There are a number of different factors that lead to a dirty roof. Depending not your climate, tree situation, and sun exposure, you may face one or more of these problems. Below we will look at common culprits.

Fire Moss

Fire moss is a regular roof malady. It looks like green grass growing around the shingles. If you let it get out of hand, it will grow up under the shingles and damage your roof.

Gloeocapsa Magma

This is the most common roof issue. Gloeocapsa magma is what creates the unsightly black streaks on top of houses. These algae will break down the limestone in your shingles.

Overhanging Branches

Tall trees that drop leaves on the roof will collect water. If not cleaned, this moisture will develop into rot.

Collect the Tools

For a good roof cleaning, you’ll need the right tools. The following is a list of what you will need for the job:

  • Ladder
  • Garden hose
  • Chemical sprayer attachment
  • Bleach
  • Leaf blower

Yet, before you climb up on the roof, you’ll want to choose the right day for the task.

Check the Weather

There are a few things to consider for the day you plan roof washing.

On sunny days, the heat will evaporate the chemical solution too quickly. It will also be very hot on the roof.

Make sure the forecast is not predicting rain or wind. Safety is the most important factor when working at elevation.

A calm, overcast, and cool day is your best bet.

How to Clean Your Roof

In the sprayer, mix equal parts water and chlorinated bleach. Attach the hopper to the hose. Carefully use the ladder to climb up on the roof.

Spray the solution over the entirety of the roof. Even if you don’t see algae in some areas, the bleach will offer preventative measures.

For the most effective results, give the solution about 20 minutes to soak in. After that, rinse the roof off with clean water.

The first half of the job is complete.

Wait to Remove the Debris

Don’t expect immediate results. The bleach solution will take some time to kill the algae. Keep an eye on how it looks. After a few days, most of the growth should come loose.

At this point, you can clean off the leaves, moss, and algae with the leaf blower.

This process can be repeated any time the growth returns.

Enjoy Your Restored Roof
