Trip to Bolivia

In Jun/Jul we had the great opportunity to go down to Santa Cruz, Bolivia to spend time at the Haven of Hope orphanage.  Haven of Hope International help run an orphanage that is the home to 42 kids.  Our goal is to rescue, love, restore and equip the children in our care.  At Haven of Hope International, we believe that every child has a destiny to fulfill.  Without family support, that is nearly impossible. We believe that our model has established a true “Haven of Hope” that will provide children the opportunity that every child deserves.  Haven of Hope International is committed to supporting the staff on the ground so they can provide the best possible experience for the children; a family atmosphere that fosters true restoration and growth, physically, spiritually and emotionally.

Why the difference in roof cleaning pricing?

Fort Myers Roof Cleaning, Naples Roof Cleaning, Paver Sealing


When getting Naples or Fort Myers roof cleaning quotes, why Is there such a big difference in roof cleaning company prices?

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

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. 

Insurance companies dropping people for dirty roofs

We find there are a lot of homeowners with shingled roofs shortening the lifespan of their roof by not cleaning it. Research shows that the bacteria within the mold and algae on your roof actually feeds off the limestone and other materials within the shingles on your roof. By not cleaning your shingle roof you allow that bacteria to grow and grow continuing to eat away at your roof which will shorten the lifespan dramatically. Insurance companies have caught wind of this and are now dropping homeowners from coverage who have dirty roofs. Check out this video:

Clean your roof so your roof will last longer is the bottom line. A roof cleaning is a great investment as premature roof repairs and roof replacements are extremely costly.


Living Smart: Roof Cleaning

by Angie Hicks, Founder of Angie’s List

You may have the most attractive landscaping, beautiful windows and charming mailbox, but black streaks running down your roof can ruin your home’s curb appeal.

What causes those dark marks, and what can be done to eradicate them?

Roof experts who are highly rated by members of Angie’s List say the source is an algae called Gloeocapsa magma. And depending on the age and condition of your roof, cleaning may be the most cost-effective solution, since it’s about 5 to 10 percent of the price of a roof replacement, which can be as much as $10,000.

Algae-caused marking isn’t preventable but can be removed, though not always permanently. The algae survive through photosynthesis and by feeding on limestone filler used in asphalt shingles.

Black marks became a problem about 20 years ago, when manufacturers began adding limestone granules to add weight to material used to coat shingles.

Roof experts tell our researchers that though other components are being added to shingles to hinder algae growth, they still get calls to deal with black marks on relatively new roofs. They say that while shingle manufacturers offer products treated with copper or zinc to inhibit algae growth, their effect wears down over time.

The Value of Curb Appeal

Creating curb appeal is a wise investment that often requires brains and brawn, but not necessarily a big budget, says Jeffrey Fick, winner of the National Association of the Remodeling Industry's 2014 Contractor of the Year award for residential exteriors.

He goes on to say, "It doesn't matter if your home's worth is $50,000 or $500,000, how it looks from the street certainly affects the property's value:'

How much more would you pay for the house on the right?


The only difference between the two pictures is the one on the right is after the homeowner had their house, walkways and roof cleaned.

In a recent article titled "12 Upkeep Ideas to Add Curb Appeal" Alexandra Bandon from This Old House Online listed the following as the top seven:

1. Clean your windows

2. Fix up your front door

3. Get rid of rotten wood

4. Repair/Clean your roof

5. Polish up paths and patios

6. Spruce up your exteriors

7. Renew porches and decks

Can hiring a roof cleaning company impact the warranty on your tile roof? Absolutely.

As a homeowner, it's critical you understand the most important warranty you've got on your home - your roof.

Most reputable builders offer a 20-year to lifetime warranty on their tile products, protecting you from leak-related damage due to manufacturing defects. Among other things, these warranties do not typically cover damage to the tiles resulting from traffic on the roof.

In a recent review of the most prevalent builders in the Southwest Florida region, their roofing contractors/suppliers (Eagle Roofing, Hanson, and Boral Roofing) provided clear guidance for proper protection of their roofs.

In a letter to new owners, they present virtually the same clear direction:

"To assure maximum benefits from your tile roof, minimize walking on the roof to avoid damaging tiles.'

Only one company in Southwest Florida has a proven technology and process to provide a superior cleaning without anyone stepping foot on your roof. Allied Roof Cleaning uses low pressure cleaning and does NOT walk on the surface of your roof. Most pressure washers use systems that generate 3,500 psi. They typically walk on the roof keeping the tip inches from the surface of the tile.
