Why the difference in roof cleaning pricing?


Why Is there such a big price difference in Roof Cleaning Companies?

We get asked this question all the time; especially when the homeowner is new to Florida and having to clean their tile roof.  It really comes down to level of professionalism, method, supply/demand and experience.  Over the next couple of weeks, I’ll address each facet so that the answer might be more clear.

Level of Professionalism

Pressure washing is one of those businesses where there really isn’t a barrier to entry.  All you need to do is get a business license, a truck, trailer (with a water tank and pressure washer) and a ladder and you’re in business.  In Lee County alone they probably issue 50-100 business licenses a year for people getting into this business.  Unfortunately, the majority aren’t in business 1 year later.  Most can’t make it through the summer down lull or run into issues when they damage customer’s homes and just close their doors.  Just go on Craig’s list during the summer and you’ll see people trying to unload their rig or equipment. 

Low Pressure Chemical Treatment /Soft Wash


At Allied Roof Cleaning we use low pressure (i.e. about 100 to 110 psi)  to apply our chemical treatment to clean roofs.  Our solution is made up of highly diluted chlorine and an eco-friendly soap.  The solution is applied by our technicians via lifts and ladders and instantly cleans the roof tiles. 

As previously mentioned in our blog on high pressure cleaning of roof tiles, the tile manufacturers recommend low pressure and a chlorine wash to clean the roof tiles.  Depending on how dirty the roof is we may have to put a couple of coats on to clean the roof completely.  We can normally clean a 4,000 sq ft roof in about 3-4 hours depending on the severity of the mold and mildew. 

We continually look for the best way to clean roofs and believe our method is the best.  Using a chemical wash that include a highly diluted chlorine does have it challenges.  You must protect plants and ensure you rinse any surface that comes in contact with the solution.  We have one person dedicated to watering before, during and after cleaning the roof and both crew members work to funnel any chemical away from delicate areas.  We also tarp sensitive plants to minimum exposure to the chemical as well. 

Bio-Friendly/Rain Activated Cleaners


This is hard to talk about without naming the actual product but I’ll do my best to describe this solution in broad terms.  Several companies use a product that is promoted as completely bio-friendly and is activated by the rain.  Once it’s applied it will slowly work over a period of time and will eventually clean your roof.  The benefit from this rain activated process is that it has no negative impact on plants that is sometime associated with those who use a chlorine based process.  The details of what’s in the product is normally hidden under the banner of a trade mark name but you can tell they are using it if they say “it’s activated by the rain and works over time”. 

How Do I Clean My Tile Roof? (Pressure Washing Recap)




This is the question that everyone asks when they either get a notice from their Home Owner’s Association or see that their roof is dirty and want to have it cleaned.  In an attempt not to confuse the heck out of you I’m going to simplify the different processes out there into 3 different categories.  Soft wash or low pressure, high pressure washing and delayed rain activated cleaning. 

Why Do We Clean Our Roofs In SW Florida?


Over the next coming months, I am going to attempt to answer many of the common questions people have about roof cleaning in Florida.  Today we are going to attempt to answer a question many people, especially those who are from states that didn’t have to deal with the thought of roof cleaning, have about why we even clean the roofs.

Here in Florida with the heat, humidity and rain that is a part of our daily existence, we are a perfect “petri dish” for mold and mildew to grow.  We have all the essential ingredients and as a result any shaded surface that retains water and dirt will become black with mold and mildew in a very short amount of time.  The more porous the surface, such as concrete, the faster the growth.  That is why on north facing sides of buildings and roofs you will find to be the most dirty.
