Roof Cleaning Fairfax, Fairfax County Va.

Welcome to the blog of American-ProTech, TheRoofCleaningCompnay.Com.   Here we’ll document a day’s events often with pictures.  For those researching or considering roof cleaning for your home or business, feel free to look over our website or better yet, give us a call for a no obligation consultation.  We’ll answer and and all questions that you may have as well as provide you with a quote to rid your home of those embarassing streaks and stains.

We were eradicating moss on a roof cleaning project in the heart of Fairfax when a very kind couple paused from their walk to have a look.  We ended up chit chatting a bit.  They had a few questions about our process and then gave us their address from right down the street and asked for a quote as well.

Fast forward about 45 minutes, and we were prepping their home for roof cleaning too.  The man of the house was a retired Navy veteran, and being a vet myself, well lets just say we look after one another  😉   Have a a look at the before and after pictures of their home below:

It’s still wet in the after photo, yet the results are quite dramatic – they always are. And aside from removing those unsightly roof stains caused by a form of algae, we also eradicated a rather substantial moss AND lichen colony growing on the right side of his roof.    The latter two biological organisms are quite damaging to shingles, so the homeowner got two very important things accomplished for one reasonable cost:  the curb appeal of this home was improved instantly by eliminating those ugly stains and streaks, and the damage being caused by the lichen and moss was stopped instantly.  The latter will literally  add years of life to that roof.

If your Fairfax home is need of a professional roof cleaning, give us a call.  There’s never any sales pressure.  We’ll simply answer any and all of your questions and present you with facts.  And then if you hire us, we’ll make your roof and your home look great again!

Thanks for visiting our blog.  We hope to hear from you.  Call 571 250 9650 or complete a roof cleaning quote request form.

Roof Stains?

Those dark streaks and stains are quite unsightly, but just what exactly causes them?   We’ve heard many theories from home owners and business owners throughout Maryland and Northern Virginia. 

‘I think it’s residue from jet fuel’ said one homeowner who happened to live near the approach at Dulles Airport.

Another thought it was where the ‘tar’ was leaching through the shingles.

Is it mold?  Absolutely not.  Yet you’ll see where some unscrupulous folks would like you to believe that it is though, through misleading marketing material.  Shame on them.  

Frankly speaking, most folks don’t know what it is unless they’ve done some research and even then, one has to wade the the misnomers out there, as there are lots of them.   It’s nothing more than an algae, generically a blue-green algae.  Now to be more specific, this blue-green algae has a scientific name, gloecapsa magma.  Furthermore, it’s technically a cyanobacteria.   That sounds a bit scary, doesn’t it?  

The roofing manufacturers state clearly that stains from this algae are predominately aesthetic.   They are indeed quite unsightly.  Yet there is no need to prematurely replace an otherwise perfectly good roof due solely to roof stains.  The can be safely and properly removed for a small fraction of what a new roof would cost.  A very small fraction.

The important take away here is that pressure washers of any sort should NEVER be used to clean asphalt (aka fiberglass) shingles, never!  Don’t take our word for it, that’s straight from the likes of GAF Elk, CertainTeed and Tamco to name a few.

Instead, those same major shingle manufacturers have mandated a pressure-free, chemical process to rid the shingles of those embarrassing stains and streaks.  And that’s exactly what we at American-ProTech specialize in.  Give us a call and we’ll gladly answer any additional questions you may have as we provide no obligation consultations.  

In our next article, we’ll explain why those ugly roof stains only started to be a nuisance around here in the last decade or two.
