Is Your Roof Turning Green? How to Get it Clean

Alpharetta GA Spray Nozzle on a Pressure Washer

A green roof is usually caused by the growth of moss or algae. It often happens on homes that are built under the shade of tall trees or other buildings that prevent sunlight from reaching the roof to dry it out.

What can you do to get rid of that ugly green scum on your roof?

Clear away the shade.
Get rid of the foliage and branches that are preventing your roof from drying and catching the sun rays.

Rent or purchase a pressure washer.
Choose a machine that offers an angled tip and very low power setting since roofs need to be cleaned gently.

Clean the gutters.
Remove debris from the gutters around your roof so that the water and soap runoff will have somewhere to go.

Find a secure ladder.
Your life depends on having a very safe ladder while you clean your roof! Find someone to act as your spotter, too.

Choose an eco-friendly detergent.
Bleach is effective, but it will kill plants around your home and can discolor the walls.

Put on sturdy shoes.
Don’t take an unnecessary risk by wearing flip flops!

Work your way from the farthest corner back towards the ladder.
Avoid having to walk on a slippery, soapy, wet roof. Start at the farthest point away from the ladder and work your way back so that you’re always standing on dry shingles.

Yes, it is possible to clean your green roof on your own. But as you might imagine, it’s a time-consuming and risky project. Additionally, you can permanently damage your roof if you don’t know what you’re doing.

For the best results, call in an Alpharetta professional pressure washing company to get rid of your green roof!

Wow! I didn't know my driveway was white. Alpharetta Pressure Washing did the best job I have ever seen on cleaning our driveway. Two of my neighbors came over while he was pressure washing the drive and contracted them to do their driveways too.


Excellent service, I highly recommend Alpharetta Pressure Washing. The work they did on my vinyl siding was first-rate quality.


Alpharetta Pressure Washing did an amazing job on my home's brick driveway. Years of build up have been removed and the brick is beautiful. Nice job.


We recently re-painted our house and spilled paint all over the driveway and our deck. Alpharetta Pressure Washing was able to clean up our mess without damaging the paint on our house or deck.


What a remarkable service, Alpharetta Pressure Washing cleaned my house siding, concrete drive, and sidewalk. The quality of the work is first class.


Great value and quality work. My driveway and the vinyl siding on the house had years of mold. Alpharetta Pressure Washing was able to remove the mold and now our house sparkles. Will use again for all of our tough cleaning projects.
