What is Roof Cleaning?

Our roof cleaning service removes/kills the living organisms on your roof. The results are seen the same day. It is good to keep your roof clean. Proper maintenance of your roof, like other things around your home will save you money in the long run. How much would it cost to replace your roof? Our pricing to clean it and make it look brand new is about 10% of the cost to replace it.  Other companies/services/products  offer results that take much longer. Sometimes it takes 6 months to a few years to begin to see the results. Yea, Really! I don’t know about you, but I would like to see what I paid for the same day. Some products, like zinc strips, do work. Zinc strips take a few years, and only work a foot or 2 below the strip. Can you imagine a roof full of zinc strips? Some other roof cleaning methods require pressure. Using pressure to clean a roof obviously sounds like not the best idea. These companies/methods will hide pressure washing by calling it a low pressure rinse or wash. Pressure washing a roof can and will void your warranty. If the shingle companies know this, you should too!

Our proven method to clean roofs provides affordable same day results. Before we leave you have a new roof, at a fraction of the cost to replace it! Our roof cleaning method is a non pressure method that has cleaned hundreds of roofs in Southern Maryland before yours. We do not void warranties.

Even low pressure could cause damage.

Roof Cleaning is more than just curb appeal or the appearance of the roof. The stains on your roof are living organisms that are breaking down your roof.  Some companies try to fool you and call it “rinsing” or low pressure, its still pressure washing. Any pressure at all on the shingles can damage and remove the granules in the shingle.

Gloeocapsamagma, “GCM”, the black stain, is an airborne bacterial spore, that travels from roof to roof. It is clear, when it first lands on your roof. Over time the “GCM” grows and builds a UV protection barrier. That is the black color you see.

Here is a before picture of an infected roof, that may look just like yours?

Non-Pressure Roof Cleaning In Maryland

Roof cleaning is an absolute must not only for curb appeal but for extending the life of the roof. Algae, lichens, and moss are not only unsightly but they also cause roof damage over time as the microorganisms feed on the roofing material. If you are planning on selling your home then consider cleaning your roof to recover a few more dollars in the sale price. Many homeowners lose thousands of dollars in a sale because homebuyers misinterpret a dirty roof to mean a roof that needs repairs. For the price it takes to get the roof cleaned, the return on investment is very significant. Without a doubt, it is well worth the investment.
There are several roof cleaning methods but not all of them might be safe for your roof. For this reason, you need the services of an insured roofing expert to ensure that only non-pressure cleaning is performed. Also, the quality of the cleaning products is equally as important as the cleaning method used.
That is why more and more customers in Maryland rely on the trusted services of GutterDogs. utilizes only those roof cleaning methods that are proven to be safe for all roofing materials. Our methods are approved by ARMA, Owens Corning, and GAF.
Also, provides a 5-year No Stain Guarantee for all whole  roof cleaning services. We are confident in our workmanship and professional delivery and customers appreciate the fact that we not only stand by our work but guarantee it.

Roof cleaning Howell Michigan 48843, Got Ugly Shingles???

Got ugly shingles and thinking about roof cleaning as an option, vs replacing the roof?

Got the black stains on your roof and wondering if it can be cleaned safely? There are some things to think about, with what is out there for roof cleaning, in Howell Michigan.

As with all the exterior cleaning services Gutterdogs provides. The first thing is to understand what needs to be removed, especially roof cleaning. Not just go at everything with high pressure. Consider the granuels on the shingle. Just over time they fall out with age. Now consider putting a pressure washer on those shingles. We have seen many roofs that have been abused by this method. They look fine right after, but only a few months later…

Watch this video:


The black staining, making your shingles ugly, is a bacteria called Goleo capsa magma.

GCM for short, has a rooting structure in the shingles. Even low pressure will cause granule loss. That shortens the life of the shingles, and can void any warranty on that roof.  The next thing to understand is how did my shingles get ugly, why should you clean them? The organisms living on the roof, Yea! living organisms, are eating your roof! Shortening the life of it. Insurance companies are finding this out too! We will get to that in a moment.

What we have seen is that once the GCM has taken a good hold on your roof. The next thing that shows up on the roof is moss and lichens. NOW time is really running out, to save the roof.
