Washington D.C. Roof Washing

You might think that washing your roof isn’t necessary. Why would someone spend time washing their roof? It’s not like it’s a room in your house!

Unfortunately, a few problems can arise when your roof doesn’t get the proper cleaning it needs.
When your roof doesn’t get the cleaning it needs, algae, lichens and moss will start to grow on it.
This causes your roof shingles to start wearing away and wood rot on your roof deck.  These can be very expensive to repair.

Roof shingles cause water to move rather than remain on your roof. Once they’ve completely worn away, there’s nothing that will hold back water from coming through.

You certainly don’t want that to happen!
Now when you think of doing it yourself, you know you put yourself at risk.
There’s a greater risk of injuring yourself.

We don’t want that to happen to you.

Roof Cleaning Tips and Tricks

The good news is that there are some things you can do yourself to take care of your roof. We’ll be referring to algae/lichens/moss as just algae for now.

  • Buy your cleaning chemicals from reputable suppliers. If you don’t feel that you can trust a supplier 100%, do not buy from them. Reputable suppliers will have a range of different formulas in stock because they know not every roof is the same.


  • There are two ways of cleaning your roof. One is power washing, which is the use of pressurized water to force algae off your roof. The second is just using chemicals. For power washing, click here to see our guide


  • If you’re going to do do it yourself, set aside a whole afternoon because there’s going to be a LOT of work. Or you could just call us!

A Little More About Algae...

​If you were wondering what algae exactly does to your roof, here’s a quick explanation.

Algae is a living thing and grows on your roof because it feeds on limestone filler commonly found in roof shingles. This wears away your roof’s shingles and takes years off your roof’s lifespan.

Replacing a roof can cost $10,000+, so it’s quite expensive!
